"I'm not sure" and "I don't know" are the 2 most under-used phrases on the internet. When I hear that, I have confidence that I'm listening to an honest person. These videos are great. VERY underrated...
Wonderful concise explanations of Grow Light LED technology and parameters useful for making educated decisions on purchasing the appropriate product for any gardeners specific requirements.
Thanks 👏🏻👏🏻👏🏻
Very good work.
1)Objection on your statement at time line 14:40. using aluminum back plat is natural cooling systim, reduce power consumption,( required fan unit cost and power consumption)inctease efficiency and life of LED lamp.
2) LED light Having very good life span , typically 40,000 to 50,000 hrs. Light unit life depend up on power supply (PSU) which deive LED'S.normaly PSU die depending on quantity and way the wiring done.
Very clear now what I need to look for when purchasing a grow light. Thank you for the concise information.
Thank you so much for explaining about the lights im deciding what light to use for bat plants which i will be growing by seeds.
Thank you so much for explaining
Thank you so much. Very interesting and interesting information
Very useful information, thank you💚🙃
Great information. Thanks for honest explanation 👍👍
Thank you! Highly educational
Love your work 👍
Great info thanks!
You shouldn't knock the dimmable lights until you try one. I used to not care about the feature until two of my lights came with them. Now they're my go to for their versatility. Something to keep in mind is that raising your light doesn't reduce it's heat output.
I’ll share this with my Grow group
SUPERB!!!!!!
thaaaaaaaaaaaaaaank u !
Please add to this video an opinion on light movers. They do have some disadvantages, but also great benefits.
I Use The Bestva D.C Series The 4000w Version LoL The 2 Lm301B Models I have uses 450w And the Classic Bestva D.C 4000 uses 615 Watts and I also have a WILLS Full Spectrum 2000w CREE COB. It uses 450 Watts
Mate u've nailed em all! Thanks a lot!
Best regards. Thanks for your information. Any thoughts on using a combination of LED light s pectrum with a 450 Watt Metal Halide for Veg. Then HPS for Bloom.? Transformer has dimmer capacity. Or would you think a full out LED set up would bring better results? Once again best regards and appreciate your thoughts on this combination?
Great info! Where is the link you referred to?
It would be interesting to make a comparison between the led cree cxb 3590 vs quantum board.
So far I can't find a video on this topic and it seems to me that he believes cxb is superior. Thanks.
Dang some of the commenters here are mean, what the heck? Thanks for the video, and sorry people didn’t have the decency to voice their disagreements more politely.
To correct his highness here on a few point here, I would say that it is correct to measure a PAR value in ppfd. The amount of photosynthetically-active radiation is expressed in the number of usable photons falling in a given unit of time on a unit of area. Also, white light is a combination of red, green, and blue, therefore contains all of them. If you look at the bottom of a leaf that grows under white light you will still see that the leaf looks green. That means that you see the green light penetrating the leaf cells. White light can be supplemented by blue or red diodes and is no less efficient than the ugly blurple monster. BTW, looks like the PAR spectrum must be broadened to reach both the UVA and the far red parts of EM spectrum. Those waves are responsible for plans morphology and production of such metabolites as carotenoids, tepenes, and cannabinoids.
Any thoughts or comments on the grow light bulbs that can just go into a lamp? Obviously only used for a small space- but I grabbed one from the dollar store for my grapefruit tree which stays indoor during cooler weather (which is the majority of our year in Northern Ontario). Total waste of time?
mostly useless.
Great information and thank you for explaining what plants need so well. I still struggle and feel like I go round in circles on Amazon with all the grow lights available. Cost is a consideration. I do look for LED’s, the PPFD and spectra. Usually most don’t provide what is needed. I just start in March my flowering annual, tomatoes and peppers. What still confuses me is do I need the higher PPFD since by end of May all my plants will go outside?
If plants go outside for the summer, the PPFD value is less important. In winter you are mostly trying to coast them along until they get outside.
I took tomato plants out of my grow room a few months ago(actually they were clips) to give to a friend. It took at least a week before they wouldn't wilt in direct sunlight. Evidently, ambient light is a lot more powerful than my grow lights.
So when they say you need to condition your indoor seedlings, you know what to expect.
Hello there,
I am confused a little. I said not to buy any LED Grow light without the green spectrum but the future you recommended from Amazon does not have any green spectrum (or any mentions of it). Can you, please, explain that discrepancy?
Thank you. Happy Holidays.
I don't follow what you are saying. I said an LED light should have some green, and I thick all of the ones from Amazon have some green. Green is not needed but it does help with plant growth.
@Garden Fundamentals have you personally used many led grow lights or other "older" lighting technologies for comparison?
I have used light for 40 years: all kinds. But that does not matter - the info in this video is based on scientific knowledge - not my experiences.
@@Gardenfundamentals1 You should at some point do a follow up and dive into "Beyond PAR". Kinda interesting how the research keeps trickling out that plants do benefit in many ways by light outside of "PAR". It's like our smartest NASA types are letting the Chinese spoon feed us 1 nm at a time. Great way to pick growers pockets I guess selling them something "new" over and over
you are a genius
You must mention in the video AND the content box below, any time you are getting a commission or benefit from a link you share. If amazon find out you don't do it in both, they can withdraw your affiliation status.
I live in California where it is quite hot and to place seedlings under a T8 florescent lamp has just proven too hot in any season. Soil temp rises and germination rates fall. I have opted to try an LED lamps with the expectation that I will be able to get equal light and greater distance from the plants thus not heating the soil quite as bad. May I ask your thoughts on this?
A fan on a T8 - and you won't increase temperature at the seedlings above the room temperature. LED lights will give off less heat, but they still give off heat.
@@Gardenfundamentals1 in the retro t8's (florescent replacements), it's the ballasts that get the hottest. I've been running 23) 4' lamps divided by 4 ballasts. Anyone interested in using shop lights retro to LED, you must have an electronic ballast. Try to mount the ballast outside the grow room.
Good stuff, but the research ive seen all put white light as superior in yield
What research are you referring to? The light absorbed by plants is well understood - I doubt white light is better than the light they need.
@@Gardenfundamentals1 most research done by Dr Bruce Bugbee state White as superior, sure blue chips might be more effective on paper but overall White is better, ex th-cam.com/video/dXkYPN3HD6A/w-d-xo.html
How far apart should the LED shop lights be from the seed trays?
Do you mean how high? As close as possible.
Not completely accurate around white light (300-800) and purple lights. It might 'seem' less efficient because PAR is 400-700 BUT this is based on OLD science we now know that when used used in combination with other spectrums 300-400 and 700-800 contributes to photosynthesis. So the PPE might be lower, but the actual photosynthesis conversion is still happening. th-cam.com/video/UZO8Fb0ryW8/w-d-xo.html
Glad i watched this video, the market and videos are flooded with 99.99999% of info about weed and its really annoying. I dont care about how many “flowers” i can get into a space.. i dont want a veg and a flower mode.. im growing lemons and oranges and grapefruits.. i dont care about dAnK nUg BrUv
just put some cheap white lights in with your blurple....lol....blurple?
U r making us confused too 😂 by talking slooowwlyy 😂
Fans are something to break=junk. The daisy chain you showed is for dimming only. Do a little research before you do how to videos LoL 😂
Daisy chaining can also be used to provide electricity - ever heard of a power bar?
Even more confused !!!
The whole review is a joke blurple lights suck
Strange - they have been used for quite some time - and very successfully.
@@Gardenfundamentals1 global lights use too much electricity they run hot and are very inefficient why would you ever use purple lights in 2022 it's a joke
@@Gardenfundamentals1 purple light = red light district , lol
There is too much on Growers mind already . Who cares for all of those college degree words. Hydro Farm Radiant 8 is the way to go. By all parameters it is the closest thing to sunlight light . Get 450 to 1050 true watts out of the same light. Either vented or not vented, Dimmable or 4 position power selector models are available. LED lighting has very limited light spectrum, and plants are very sensitive to color of light while HPS lighting provides full spectrum and 2 x 2 ft light reflectors of Radiant 8 cover area of 4 by 4 ft ( or even more) of growth area. Contact me and I will tell how to get pre-owned sets.
Those are just the normal vocabulary. Don't make it sound like video is hard to understand, when in reality it's your inability to understand the meaning of the terms used. Stop doing that. It makes you look judgemental and blaming instead of learning.
