I chose to use CFL bulbs in my house for a number of reasons. Bulbs with excellent wavelengths for plant growth can easily found hardware stores so finding a specialty shop or ordering online is not necessary in most areas.
The light fixtures are either fairly cheap or the bulbs can be used in house hold fixtures. The fixtures for CFL are often long tubes allowing you to easily fit more plants under them. Having individual light gives me the flexibility to us what I need when I need it optimizing power consumption
They also don’t put off a tone of heat allowing you to operate more lights if you desire without having to worry about heat issues.
The initial investment is lower than the other lighting technologies for instance both of these combine cost me just over 50$. Because these set ups hold fewer watts of bulbs their power consumption is much lower. Even though some of the other technologies are more power efficient they typically come in single units that consume larger volumes of power. The lower energy output makes it much easier to start your seedlings and tender plants inside. Some of the larger systems can cause issues with your seedlings most often related to heat output.
One of the downfalls of using these CFL bulbs is you generally cant produce full size things like tomatoes and peppers. They will still fruit if you chose medium and small bodied fruit but not to the same density as the same plants outside or under the more costly systems.
If your looking for light systems for starting seedlings and lower energy plant growth inside during the winter I recommend simple CFL systems. With higher energy systems you can get closer to producing your favorite Tomato or Citrus tree inside during the LONG COLD WINTER
On the next episode in this series we are going to go through the basics of growing inside. Click here to go to the Indoor Growing Playlist.

I love how he gets the inflection in his voice when he gives the light specs . He loves his job . It's cool. Thanks for a great , informative video . Well done .
Love the way you broke all that down! I've been wanting to know about everything you mentioned here. Thanks for your time bud!
+Keith Collar my pleasure! I am glad you enjoyed it!
+Keith Collura Likewise, I learned heaps from this video!
Man, thank you for explaining this so thoroughly! I've been wondering which is better. I was using regular incandescent bulbs for awhile the switched to cfl's out of trying to lower my electric bill but wasn't sure if it was ok. Very informative! Great job!!
Stephen, I looked a few videos that was just too technical for what I was looking for to give my indoor plants the light they need. This video was very informative and very easy to understand. I now know a few of my light are good and a few are not doing anything but using electricity. Now I know what to look for the next time I purchase a grow light or just the CFL bulbs. Great job!
Great Video Ive Been Using CFL And LED Both With A Great Grow Rate I Used CFL Only For Years Then I Purched A LED Light Set Of 250 LEDS At 45 Wats From EBAY Works Great
Fabulous! Spent 2 hours surfing the web until I found your information :-)
Tulasi Devi I did the same thing one day which is why I did this video! I am glad you liked it! There are more links on the blog post I put on my website if your looking for more information.
Same lmao
This guy is so clear and concise. Really well done.
I have a windowless room but I love indoor plants very much so I've been supplementing mine with a 6500K cool white 8W CFL and 12W warm white cheap grow light both about 3 feet away from my plants. I've been so worried about their health but it's been 3 months and they're still thriving with no issues at all. This has been very helpful! Now I know that all I need to do is find the highest watt CFL available at the hardware. Thank you so much!
Thanks for your clear and thorough explanation. Your advice has led me to understand that the more expensive LED lighting is not necessary for my needs and I will save money and get excellent results with CFL bulbs.
+Rachael Welt I am truly glad I could help my friend!
His voice is so soothing.... Very informative vid! Thank you so much
Y Nunez I am glad you enjoyed it!
Thanks a lot Stephen! Fluorescent for me then, I am about to start seedlings for the first time for next year and I found your research very interesting!
Probably one of the best "explainer" videos on TH-cam.
Thats a fancy set up for just growing “tomatoes” lol
Thank goodness he has a filter, wouldn't want to smell up the house like tomatoes! 🤣
@@LuisCasstle ngl tomatoes do smell like garbage
@@movingname3585 I really love the tomato plant smell, but yeah, they do actually have a strong scent. I've never been around a cannabis plant in full bloom to compare, yet, but I''ll bet they are MUCH stronger. The real difference is that neighbors aren't going to complain about tomato stink being blasted out a vent. With legal cannabis cultivation around the corner here in NY, I'm pretty darn interested in legitimately setting up a way overbuilt indoor veggie grow to learn the ins and outs, gardening takes time and patience to learn. Leaning towards LED, mostly for the energy savings, paying to power a sodium lamp for veggies is pure madness.
@@All4Grogg go with a kingbrite qb they are absolutely amazing and if you dont add the fancy diodes are even cheaper but as power goes just remember a watt is a watt (some people don't understand that sometimes) if you want to add any different spectrums to supplement the main lights use separate boards and if you want to add uv flourecent is still the best technology mainly cause uv destroys everything
I like the way you explain things. Great teacher!
+Lindy Thank you Linda! I hope I can help people grow food at home!
Thank you for explaining how different 💡 lightbulb work now it’s so much easier make my plants grow
I have spent months trying to find a video that explains lighting in layman's terms. Thank you. I gotta sub
In fact, there is no best plant light, only the plant light that is most suitable for your plant.
So very helpful. I've been trying to find info on grow lights all day and this has been the most informative video. Thank you!!
I'll help you shop for a grow light any time 😍😂
Great information on grow lights, Stephen!
Thank you my friend!
thankyou so much! I've spent weeks reading about bulbs, and driving myself crazy. I'd decided on daylight led, and was gonna order, but thought I'd have one last search, and try some vids instead of reading. Now I'm getting cfl. Thankyou again, from rainy England, and from my bff in snowy Vermont.
Thank you for sharing all that information. I'm setting up an indoor grow room for the first time,and this was perfect for showing me my options.
Fantastic ! In an upcoming episode I hope to show how I set mine up and some things to think of when doing your own.
Great video! Super informative!
Thank you my friend ! Glad you enjoyed it!
Hey look who it is
wdym to grow at your house to grow what?
And then you choose the worst possible grow lamp😂😂
The comments are gold just like this video
Thanks for that. I actually understood it! I’m not a technical type at all so it’s good to find a video that’s not over my head...
Greetings from England xxx
Starting at 6:22 exactly what I was looking for, thanks!
u have no idea how much that video helped me bro, i took notes. very very very good! thanks, u saved me hours of research so thanks!
I am so wry glad I could help my friend ! Let me know if you have any questions !
Thank you for this! I finally feel like I understand this topic.
Finally an in-depth explanation! Great video
I watched three videos on grow lights but yours really clicked. Thank you for the break down!
Brother, you have to know that led grow light is the future of growth light.
tnx very informative.
yes I turn them on that long .
+Valerie Andawey I am glad I could help!
My tomatoes are growing under 150W HPS. And they smells amazing! ;P
I bet they do!
Buy a CMH. You will thank me. HPS is old school.
SK Live buy LED quantum board lights . everything else is old news
Buy not yet invented bulbs. They put the current ones to shame. You'll thank me later.
Lol.
How wonderfully informative! Your personality is sincere and the video was a pleasure too watch. Thankyou!!!
My friend did 3 autoflower in a white closet with like 15 of those swirly Walmart lights. We thought he was crazy but he pulled over a pound of those 3 plants! It was some good smoke too!!! Tasted great and was really strong! It was his 1st grow ever and was hydroponic.
"If you want to grow one and a half pound of your favorite... " *My brain: Weed* ".. tomatoes!"
Lmmfaoooooo exactly!
I like to grow canna.. *euhm euhm*.. sorry. Vegetables.
s70rk that cheeky grin as he said it to hahhaa
he was thinking of the lovely carrots he grows when he was smiling
holy moly i laughed.
Nice info mate well explained I did well with the cfls last winter and I made a bank with shop lights and 2 aquarium plant lights worked well too I am looking forward to getting started with the indoor herbs and veg this year be a month or two though.
Cheers Dave
Ill be starting mine any day now between brewing and year clean up for the year ;)
Great information, and as usual I learned something new! I am still a CFL seedling greens grower, but I'll admit the LEDs have caught my eye, but not the current prices. Definitely liked your light spectrum description for comparisons, as it puts everything in perspective.
Sheri I am really glad this was able to help you! I learnt a lot putting this one together!
I am kind of falling in love with the LED grow bar that was in the video. its smaller and would probably do what I want it to!! but your right CFL is my main system for now!
Ohhhhh thank you. Others make lighting so intimidating.
We all know he isn't growing tomatoes.
how?
A nice stinky pound of tomato
Joshua Long I am
How does the "tomato" smoke???
@@whelkshuffler carbon scrubber
Thank you! I have been looking for the non confusing reasoning.
I hope you better understand now :)
You delivered like a real expert Steve, Now I know something about lighting and especially about the CFL bulbs. Great Job Buddy Ken From Houston Texas .
Great video overview about grow light technology and the pros and cons of each. CFL has worked fine for me. It seems like the cold weather varieties prefer the blue spectrum or cool lights while the warm weather varieties such as tomatoes seem to respond better to the red spectrum or warm bulbs. Thanks for sharing!
Your likely right about the blue crops vs red crops. I could not find enough to really mention it.
I am really glad you enjoyed the video !
Another well thought out and presented video. I'm sold. I subscribed...
Thank you my friend! I am really glad you enjoyed the video!
According to TH-cam Analytics this video had the most single day views from Canada in the last 6 months! Thank you Canadians! I really do appreciate your fantastic support and great conversations we have!

It is great to run into other canadians :) I am glad I could help!
+Alberta Urban Garden Simple Organic and Sustainable It's because it's an awesome video! Thanks for doing all the research and sharing!
Just came from home depot, they hardly have anymore CFL bulbs, mostly LED. highest lumens on the LED was 1325 are they different for led as opposed to cfl?
I don't know why but your video really satisfying. Thanks this really help me a lot.
Very helpful. I have always wondered if LED for plants were safe for our eyes and now I know. Thanks for answering.
In fact, the impact of led lighting on the human body is basically negligible.
I'd like to update this four year old video with my experiences. To start with unless you go to the dollar store most stores that sell lights no longer carry cfl's in my area so they may not be worth the trouble to make a set up now unless you find and store enough for future use. Plus they along with standard florescents contain mercury which means you should dispose of them properly. Both types of florescents have a major drawback in that the wavelengths the lamps produce change over time and the light output slowly reduces so that they should be changed from six months to a year to get the best results from the output. High output florescents produce much more light but cost much more and produce a lot of heat. The Hps and metal halide are better suited for placing high above the plants to protect them from the heat. They also need to be replace at least once a year if not more often and the bulbs alone are fairly expensive. I've gone to the led's that are built for aquariums. They may have additional light wavelengths that aren't available in standard led grow lights but also are readily available. They do put out some heat but usually not enough to create a problem. The lights can have a useful life of years without any change in light color or output. As a simple gauge I have a 2x4x5 foot tall grow tent. Hanging inside are two 600watt led lights. Each light has controls for intensity and an individual on off switch. I've found that if you want thick low growing plants such as lettuce using the blue alone creates a dense leafy growth. The red light encourage taller plants and blooming. If you control the day length to the type of plants you grow and want blooming then it can happen in a week or two. All in all I've tried many different types of lights and for now I believe the led's are the best option for the money, especially if you intend to use the lights a lot. In the long run you'll likely find they are also the cheapest lights to own since you won't likely have to replace a single bulb for the life of the light. Of course there's no guarantee that the lights weren't built by someone trying to finish up the day and go home but that's the case with most things nowdays. I've got led's that have been of aquariums for years without an issue and they're exposed to high humidy and still working.
CMH is the way. Or LEC, same thing. Cheaper and better than LED's.
@@BenDover-mn5db You missed my point. Apples and oranges. I said the hps and mh were suited to being high area lighting such as lighting a large amount of plants. For raising a plant or several smaller plants the led's are far cheaper and better suited. However I also believe that as more powerful led's are produced they will eventually replace high output lights in most uses simply because they use less energy, run cooler, last longer, and most of all are readily available in select wavelengths, something that's not true of high output. True mh and hps produce a lot of lumens for the wattage but the real question is how much of that output is in wavelengths that plants can use and how much is wasted? How often do you want to change lamps and a good lamp in blue wavelengths is generally an easy hundred dollars. Replacing them twice a year can run the cost up way over led's that are for now the cheapest lumens for the dollar. And you still have to get rid of the heat from mh and hps while the led's produce only a fraction of the heat other light sources provide. At one time mh was the way most aquarium hobbyists went to raise corals that require very high lumens. Hardly anyone uses them today as it's simpler to run led's over the tanks for a lot less money and heat while the corals all seems to do better and also show better. And there's still a few who hold on to the old ways simply because they work but for now most have converted over to what they consider to be a better lighting method. If you intend to us mh or hps in growing plants then I would suggest getting complete workup on the lamps you intend to use to see how much of each wavelength they produce and how much of the lamp output is going into wavelengths the plants can't us. Figure the cost of the lamps vs the acceptable running hours before the out put changes, normally around every six months, cost of electricity for the lights, cost of running fans plus amount of fans and don't forget replacement ballasts as they normally have a useful life of around two years before they also can no longer drive the lamps at the expected wavelengths and output. Unless you have a good light meter you may be running lights that aren't producing anywhere near what you think they are so it's quiet common for people to run lamps for a couple of years until they fail not realizing that they're wasting a lot of energy on a probable output.
@@BenDover-mn5db In the end it all breaks down to what's successful for you. As far as soil goes I use a commercial mix with added perlite. After each use I add a little fresh mix to the old mix and a small amount of additional nutrients and simply water until harvest. The commercial mix is pricey but by using it over and over the cost is very reasonable and I've yet to see any problems from reusing it. Most of us don't grow plants over the long term but only over several months so the soil is renewed frequently as new plants replace old. Now the hydro beds in my greenhouse are just the opposite often holding peppers and eggplants for more than a year at a time but they get fertilized twice daily with fish tank water from my aquaculture tank. Good luck.
Wow I thought that grow light was a special light that you use for plants. Since it's in my balcony, I put the led light around 5 or 5:30 pm while outside while it's still daytime because I notice that it does bother your eyes. I don't know to much about lighting since I live in the Caribbeans. Thanks you answered my questions
I am glad I could help!
It's a video from 6 years ago at any time, but you can still learn a lot.
Thanks I am glad it’s still helpful !
Great job explaining!
Compare to all the video I watched this has the most easy to understand explaining the light difference.
I am glad I could help!
Use Blue lights if you want to grow greens (wheatgrass, lettuce, seedlings etc.).
Use Red/Blue if you want to grow fruits (i.e. tomato).
:)
I was going to mention that but I could not find any peer reviewed papers on the subject. That said I have my own experiences that are similar! Great comment thank you!
***** Unfortunately I can't cite the source where I read this. About 5 years ago I dived deeper in this subject and bought 8 units of LED panel, 90W (180x0.5W diodes) each. I chosen the blue only version as I wanted to grow wheatgrass for juicing.
The panel with 90 blue and 90 red diodes was more recommended for plants at the stage of blooming/fruit setting/ripening.
The blue/red combo isn't as effective than the 180 blue diodes version to grow green vegetation. (According that source.)
I'll have to do some digging see if I can find a source ! It seems reasonable to think it would be true !
What about weed
Yes now I can start growing "tomatoes" too!
wow,learned more in 11 minutes than---well you know thank you ,peace out and god bless
As a newbie this was Very helpful! Thank you.
Great job on video...very informative. I have a 60w CFL (4200K) full spectrum light and a 12w LED grow light (blue/red). I just planted my herbal seeds in a 18" x 30" planter. Should I light them now or wait to they pop up?
Generally people recommend putting the light on helps germination. What I say generally is I have not seen any support but i follow the practice.
I am glad you enjoyed my video. We just harvested basil from my system for tonight's supper and thyme for last nights :)
Thanks!
my pleasure! I hope you have a great indoor growing year!
+Alberta Urban Garden Simple Organic and Sustainable You are a smart guy, Very diplomatic !! rare, Congratulations, & God Bless !!
Thank you tulalevu that is very nice of you to say.
250 HPS from Lowe's. Grows good "tomatoes "
Thanks. Very informative
Nice comprehensive video! I've been using CFL's for two years in a row for winter indoor growing. Most years I have peppers and tomatoes on some of my plants within 6-8 weeks from seed! It's fairly cheap in initial costs and works great. I did an experiment using a couple LED's for young seedlings last year and I'm not sure that they hit the right spectrum for the plant based on the results. The plants just didn't start out as good as they should've.
Led need to be turned down for seedlings. They get overwhelmed and should be mostly on blue light. Is what the research I found said !
I love CFL they work for me too !
Glad you enjoyed the video !
He had me at "One and a half pounds"...until he said "tomatoes". Great video though! I'm using CFL on my "Green Tomatoes" ;)
Tomatoes, gonna love em. 😂
yes...tomatoes...
This would be a good video to revisit/update based on new technology.
I like how u talk about hps and show metal hailed
appreciate your input. I am using led lighting, is that OK? I hope. thank you. Rick!!
+Rick Schultz LED are great you will just want to make sure that they are the right spectrum!
Yes, thank you, now I can grow some "tomatoes" indoors.
Yes the high quality indoor some top shelf tomatoes
So i recently bought a white LED bulb from lowes. And added it to my blurple set up. I noticed a difference of growth rate within 3 days. It massively improved my yield
That is good to hear!
Thanks a bunch for this video. I just want to do leafy greens. I have tomatoes outside that took over my small outdoor garden
What about normal LED destined for homes
Ive used ones specified as "daylight" if i get the ones rated for 900+lumens i get ok results with lettuces and greens from about 12-18 inches above the substrate.
So when are LED lights for plants in aquariums, terrariums, and garden going to become affordable?
I just bought a submersible blue and white led for my 10 gallon for under 20 bucks. It attached wherever I put it. They even had purple ones.
Look on wish
I have been through so many readings and videos, but your video is simple and to the point, plus the feeling that you love what you do from the heart. Glad to see 1M views for a meaningful purposive content. Greeetings and respect from Egypt.
my um.... tomatoes are growing very well thanks!
I'm getting a raging clue right now.
mine keeps pointing to the left
Nate Haselton I'm gonna shoot clue glue
"tomatoes"
FUCK YEA!! that shit made me laugh so hard hahaha
fuck i lol'd
MMMM i love me some tomatos
jcast1976 They are great ;)
Thank god finally i got what i was looking for
I enjoyed watching this video.. now I have better understanding about light spectrum..
I am glad I could help! I have a video on how I grow using fluorescent lights and another on how I purchase them. I find it has helped a lot in my understanding !
Hi, that is a metal halide bulb, not a high pressure sodium bulb 3:18 But nice video!
Yofatboy124 I knew I would get caught eventually ;) I did kind of lump Metal halide together with HPS and that was more out of convenience then anything the video was getting too long adding in things like MH, Plasma ext...
Hope its alright ;)
call it HID (high intensity discharge) if you want to lump hps and mh together. =]
I heard it being advised that you shouldn't handle hps bulbs with your bare hands. The reasoning behind this is that the oils from your hand transfer to the bulb and can increase the chance of the bulb cracking due to the oil increasing the temperature of the glass.
I’ve never seen someone use a filter with tomatoes 🤔
Stinky stinky tomatoes
Thanks for the video, great explanation of light technology for growing plants inside..
I am really glad you enjoyed it !
Thankyou for these extremely informative videos! Really enjoying them.
The few who thumbs downed this vid are living in the dark.
your Punny ;) Thank you my friend! I am glad you enjoyed the video!
trainofthaughtify 😁
actualy thumb down cause some of us know this is full of crap. led suck. guys an ifiot to say hid lights arent for indoor grow caus you need venting.you need venting for fresh o2 anyways kids. back to your tiny closet grows hiding from mom,
alot use them cause they either get free gear from the company to push a product, or they sucked with big lights and think less output is better., most are conned y the color of them when theirs alot more to lighting than colour, like their lacking penetrating output, like candle power. without that your colour isnt worth anything
their well documented by salesmen idiot. and i was one. paid to lie to you kids. and i gave away free gear all the time to promote our nutes and products., your obviously new
talk about dumbass,. im not new enough to fall for weights. go grow real smoke and not the kiddy white strains for weight and is bunk smoke kids. gram a watt isnt anything to brag abut either lol
my electic bill is cheep kid. watt is a watt and is how cost is reflected. so of course you run less watt it costs less. also less return. i have no heat issues. proper chiller to cool the room. no cost son. water is free here.
|sory kiddy, your the dumbass. everyone knw it, yet most you bu my nu
tes...lol idiot chiden. been at this longer than you been alive probably little mouthy fuck stick kid
Spectrum = singular
Spectra = plural
Thanks for making this so clear!
your welcome
Great video! Thanks for being so informative and clear off all the cobweb Hehehehe . I am using CFL in my home so it is perfect for my indoor plant. I am all about leaving a smaller carbon footprint ❤️😜👍
That is great to hear!
"tomato"
A pound 🤣
we all know why we are watching this(and it's not tomatoes) weed-weed-weed bro
Stephen, excellent and informative comparison video!
Jeff I am glad you enjoyed it! Im sure in Texas you don't have much use for them but its neat information to have anyways!
I learned so much about indoor growing, maybe this will help with winter gardening here as well when I want to do something more than leafy greens.
+Alexander Legaree I find my leafy greens do much better inside :)
Apparantley I can grow them outside all year round here - I might try next winter! But I guess I'd still have to cover them as it does get to +1 or +2 here at the coldest.
The really cold hardy stuff is fine to -10 C. When you want to I can help !
Next winter we'll give it a shot!
the lights are simple to buy set up and use! I even got carrots to grow under mine this year ;)
LEDs are overhyped shit.
Yeah....that's brilliant.
you're wrong. the newer technology is amazing. they have really improved the performance over the last 5 years. imo
Mel obrien owns a flourescent bulb company.
That's why CMH's are called LED killers.
I'm here since I live in Massachusetts!
I just kicked up my system too :)
Thank YOU so much for the info, newbie here and been so confused! xoxoxo From WA State.
I took notes and have learned so much! Thank you!
I am really glad you enjoyed the video ! I should be putting out one on just CFL and Florescent tubes growing on the weekend :)
Thanks man I've just started growing "tomato's" indoors and found this vid really helpful....cheers
Did it work
Thank you so very much! I was wondering the difference between the lights. You explained to basically that even I understood lol Now I know what I would like to do. Cheers!
Glad I could help my friend!
I bought a full spectrum led from Amazon for 24.99 ...it works great im using it to grow my kratom plants in the winter ...so u can find them for decent prices ...hands down there are better ones than the one i bought but if u are balling on a budget its great.
Super informative. Thank you!
Thank you for this video. Very informative for the newbie home grower of... tomatoes.
Glad I could help.
Thank you very much, Stephen. Great information.
Wonderfully thorough, thank you!

very informative thank you for sharing your knowledge
Thank u so much for the knowledge that you're sharing. Greetings from cancun
I found some led full spectrum bulbs for my container garden that have so far been working great! The sprouts that have came up are growing very quickly, I've already have some excellent habanero seedlings I've used cfls in the past and I got all my ballasts for free since I'm an electrician and good discounts on bulbs but these purple lights are where its at! I'm definitely going to buy a few more today, the leds I'm using only draw 8 watts and output 100 watts, where when I was using my ballasts theyd draw 40+ watts per bulb or driver I forget which but the bulbs are under 10 bucks a piece, not to take away from the video I enjoyed it and it was really informative I didn't know that tge purple light could ve harmful to my eyes thanks for the heads up brother I'm definitely going to be cutting the lights while I'm working
Why do you need a purple light after you have a light that supports the full spectrum? ?
