UV and IR certainly make a difference in phenotypical expression. I have been using both on and off for roughly 5 years now. Also Guru is incorrect. IR makes MORE biomass via leaf surface area. It's not desirable biomass but it still produces more biomass. Your only supposed to use them the last 2-3 weeks of flowering during the last 2 hours of the light cycle before lights off, IF your trying to mimic nature. I have used them both for the whole grow, UV the whole grow, IR the whole grow, the last month, the last 2 weeks and so on. Using both the whole flowering period makes your plants express more like a tropical environment. Makes your buds more greasy too. Not the best idea for hash washers.
So, would you reckon to use IR in veg then & the UV like you said at end of your last script then buddy 🤔
How did you find results with IR ? Do you have some science to back this up ? The IR I mean, I know about the UV . " Your only supposed to use them the last 2-3 weeks of flowering during the last 2 hours of the light cycle before lights off, IF your trying to mimic nature" how are you mimicing nature by adding IR two hours prior to night ? This doesn't happen in nature, you don't get more IR at the end of the day in nature..
If you use it throughout veg, your plant will become lanky and tall with HORRIBLE internodal spacing. @@terrybeechlarry798
I don't know for sure, but certain areas of earth have different levels of UV, and I think max UV is typically mid day ish because as the angle changes it has to pass through more atmosphere with straight above being the most UV penetration and sunset and sunrise being the least, that's my understanding anyway which is why people in northern latitudes especially in winter have more trouble getting sufficient vitiman D from sunlight could be way off though
If true, if I was trying to mimic nature i guess I might consider where my plant originates or which part of the earth i'd like to attempt to recreate and this would also potentially change the time of light cycle i'd want to introduce UV
I think the IR diodes are basically to give off a little bit of heat and let the plants transpire more. So yeah a more tropical environment.
I don't know what u mean with greasy tho. There's noting greasy about the buds once they are dried an cured properly.
Been using Migro UVA/B fixture for 2/3 runs ..... a definite improvement in taste expression ... love it. only an 18w unit in my tent ..... highly recommended! last 3/4 weeks of flowering 2 hours 'mid' light cycle.
Your technically supposed to use the last 2 hours before lights off to mimic nature. That's what DR Bugbee says anyways. I just turn on my UV and IR on the last 15-17 days of flower and let it ride. That off and on shit is for the birds lol
did you notice smaller buds / yeild?
May have been a marginal yield reduction .... hard to quantify tbo .... but the benefits made it well worthwhile!@@j1mmyvfx
@@FunnyBonesGaming Growing for 22 years but don't know that UV is highest at noon and not at the end of the light cycle. That's why I do not listen to any so-called experienced growers because their experience is just anecdotal and they're not used to reading papers and thinking scientifically. "Simply stupid" if I may paraphrase Skoda Auto's slogan.
Idk how most uv works but the light manufacture recommends that i switch their uv diodes on for something like 4 *minutes* a day in flower, the problem is sometimes i forget to turn it off for a couple days, and you can see it takes a few days after that for the plants to bounce back and grow quickly again, however they come back with more stink and grease, I put my plants back in veg a few weeks before harvest so that helps my plants finish bulking while under the stress of uv, they are still nice and green come harvest as the lowers of the buds are already revegging. I think people worrry that switching the lights to veg at the end of flower would make the plants stop producing cannabinoids, or change their terpene profile, but i notice it only makes them more stinky, potent and massiv. Phenos that didnt smell before start smelling, especially after the reveg when you run the plant a second time, like it has reached full genetic maturity. Be careful though, some strains reveg really quickly, like within a few days, in these cases this stratedgy wont work well or will need much better timing so I wouldnt recommend this for landrace plants on the first run but it will usually work with most of the popular polyhybrids about at the moment.

I use the same pot holders with drains on my grow which is elevated and I have a drain system underneath and used robust silicone hose that allows for movement of the pots still but with a drain. they are AWESOME. I also found out that adding truck bed liner to them is smart - the salts in feed will eventually compromise the paint and cause rusting. The pumice or some soil gets between the pot and plant and just the pot shrinking and swelling from wetting and drying will wear out the paint. Truck Bed liner just makes it more awesome. I have a new AC Infinity 4x8 raised up 2 feet off the floor. I am using the brand new 8-Port controller that arrived 2 days ago. My 15L AC Infinity UIS humidifier is pre-ordered and already shipped. Got Acapulco Gold, Green Crack, Dee-Lite and OG Kush going. Photonek and Phantom lights with the AC Infinity 4x16 augmented lights and 4x11 UV augmented lights.
Much love Scotty, Grambo, and Dude(love your sweater). Thank you for the shout out.
You bet! Ty!! 🤘😁👍
Merry Christmas DGC, keep it lit for the holidays yall
The grow room is looking great
This year grow was the best for my terpenes the 3 strains came out 20% THC with a terpenes 4% and 5% and Definitely happy with the test results that I received back
I have grown cherry pie under a mars hydro light and outdoors from the same mother plant and the characteristic terpenes and potency was completely different! Indoor has a nice cherry flavor but out door was super gas with a pinch of cherry.. much stronger too 😅 both tested over 30% tho😊
Absolutely a friend and I did the same thing with blueberry pancakes last summer
Loved this episode! Talked about UV, auto watering with living soil, cloning! What a great episode keep up the good work guys
I've been running the uv and far red infrared I believe there the same the light figures from Mars hydro they clip right on the Existing grow light in between the led bars. I'm only on my 4th indoor grow I've been using it since the second grow I also gre outdoors over the summer for the first time and I have to say compared to the first grow my last 3 harvests the plants were just as if not more than my outdoor yeld also the thc content has to be hire because compared to my first indoor grow with out the uv and ir I definitely noticed the difference in the high and amount of terps. Also like I said when compared to the outdoor they were definitely on pint if not more like I said. In my opinion I won't be ever growing without them.
Great show guys! I enjoyed My evening watching 👍👍👍👍👍
A Churchwarden pipe for the Dude.. Merry Christmas guy's...
I got some hydrolocks no longer pump water through me but I like to place them on top of my pots and slows the dehydration of water tremendously adds another day between watering Scotty
Here's the picture for the 24 hr light debate. Light on vascular system is in uptake mode full on can't reverse flow.. 24 hr the leafs build and build plant energy and they will need more storage. So they need to absorb prior building blocks to do so or they don't have a choice but will gladly trade overstocks for smaller more powerful energy cells. Microorganism centipede.. Night cycle that building finally can stop and the massive need for space to store the energy can bleed out to the roots as the vascular system isn't restricting the flow. And now the leafs absorb any shape that is the right size. Once they get clogged it reverses vascular flow to take care of the business. These are my own words and the plant might have made me do it to confuse us all idk.
We are too few man ;-)
Love that LOTR Gandalf style pipe!
Im using the 4ft Fluorescent AgroMax t5 pure uv %25a/75%b supplemental lights, and I've noticed a difference.
I have a 4ft one, also. Like using 2 of the MIGRO UV 2ft fixtures, but cost less than the price of one MIGRO UV 2ft fixture. Same exact lamp, just the longer version.👍💯✌️
The heater at night is worth it in my opinion. Less chance for PM for temps to not fluxuate i believe.
Sweet set up Dude.
I definitely want the day night controller.. I just use two ink bird controllers. It's a pain.
Great show. Hitting on some very pertinent topics.
Theese are many of the pro nuences.
I had to travel several times this last year for 10 days at a time. What I found that worked best was a blended live top feeding dry food blended into the soil then just feed then on a schedule with clean water. I had amazing results. The one thing that is critical is make sure all controllers are battery backed up. Power dips and brownouts in Texas would kill my devices so I had to use a UPS.
Thanks for your amazing Show. I've found it by chance when i was looking for strains and breeders on YT ( the solfire Interview). Thanks to you i,m now mad about some ( many,many🤤)US strains and my Hobby will get much more expensive If we have legalisation this year😁
Greetings from germany
Dude best pipe and Christmas sweater ever. Send a link so I can check one out🤟🏻😂
Been running 24" T5-HO Agromax UV-A 75% / UV-B 25% bulbs for years. Burned my first crop. Now I run it in 10 minute increments 3-4 times mid-day during flower. Way more cost effective than LEDs. Still running the same bulbs 3 years later.
CMH for the win 🏆🌟🔥
closest spectrum to sunlight ☀️
Merry Christmas fellas ! DGS is the best . God bless , and a peace be with y'all !
One of my best plants ever I grew in a 2x4 in my kitchen. Make sure to open a window when you cook if you don’t have a vented oven hood though
Merry Christmas from Freedom Mountain Homestead, Elk Creek Missouri
I supervise a 25 acre floriculture farm producing around 4 million plants a year. Handwatering hanging baskets is still my favorite thing to do :)
Not a shameless plug and not affiliated with the company I am about to mention in NO WAY, SHAPE or FORM! SolaCure has a UVA/B T8 that is AMAZING! Takes your end results to the next level fo sho. JS! My hidden gem for a few years now! 💯💪🏼💪🏼🔥🔥🔥✌🏼
I grew same cuts with and without uv. It completely changed the terp profile, for the better!
Short lead me here. Good job! And just my Thang UV!
Happy holidays.
I have been using the migro uvb for 3yrs and it deffo makes it more sticky
Wheels are clutch!
Mars hydro has an excellent 3 light combo ad on for uva deep red and more normal red spectrum which increases your size and terpene production.
migro homepage: Set timer to switch the UV light on for about 2 hours in the middle of each ‘lights on’ cycle. Hang 45cm to 60cm above the grow canopy.Use only for the last 3 weeks of flowering
In addition, according to studies, there should be even better results if you activate it every other day.
You can use it for the whole flowering cycle, wont hurt the plants, 1 do 4 times 15 minutes a day, frozen
In a studio they found out that the plant has two ways to protect itself from UVB. She can adapt her leaves so that they protect themselves from UVB (only if contact with UVB has already occurred in the vegetative state). Or it produces certain cannabinoids (THVC) to protect the leaves. It therefore plays an important role that she deals with it at the end of flowering. Because if the leaves addapt which it always does in Nature there will be no difference compared to indoor with no UVB.
In addition, greenhouses can also benefit from UVB lamps because the glass absorbs UVB.

Horizonal living soil system..can heavy water and good for a week as there's a sand aquafillter in the bottom of the pots
54:45 nice caddyshack reference Scotty
I’ve never charged my biochar and it’s been 20% of my potting mix for years.
Listen guys here's the new grow room for myself as well I have a 5x5 infinity set up and I have 4x8 and 3x4 in my garage and I have a upstairs master bedroom with a walk in closet that leads out over hanging above our kitchen and it's a shell that I'm going to build a veg room that's hidden from everyone so this is my new project for this year
Merry Christmas , love the show ! God bless !
I believe that because uv is closer to blue than red, so when you add the uv it throws off the balance of red to blue ( k) color temp..
So yes more blue prevents cell elongation. This is how i understand this
Oof. I see this purpose. Uvc was mentioned recently...
Chuck Norris for sure
Hand watering for the win!!!!!!!!
I got some UVA & UVB. I see great results in veg with the UVA and ive definitely noticed stronger terps when using rhe UVB. This run ill do a side by side comparison. My 5x5 has been getting UVA from the beginning and the plants In the 4x8 for it for the first month. But I want to do UVB for 2 hrs per light cycle for the 4x8 and get some solid test results! Running 5 tents right now and Yeah it can be a lot!
I’ve got a set of uva bars on my mars fce6500, no noticeable difference in frostiness, uvb for sure does something ain’t had nothing match what I grew under cmh, gonna try some reptisun bulbs see how that works.
Mu 25w reptisun uva uvb do for sure froze the buds
@@surronzak8154 how long you run them? I know migro and solacure recommend max 4hrs
Dude showing me some leg made my holidays. Make sure to cover those nips in the grow when youre using that UV light.
Great information I’m just getting started
I've got IR leds in the security cams in my tents and no ill-effects thus far, and that's all night long through flower.
SpiderFamer's got UV on Christmas deal so one got tossed in the cart. Not much of a baseline to go by so far, but we'll see
Nice sweater and growroom Brett. Is that all Orangegasm🤔
Dam nice grow room dude.only think is the heater.metal?I've seen melted ones when it's fan burned out..I have a portable base board style no fan .convection only ...solid state as you like to say
Hey bro, he wasnt saying uv brings up terps and thc by 30% he meant it brings up terps by 30%. So if you have 3% terps and add uv lights it will bring it up 30% which is like 3.8%
Dude, how do we really know the sun is the best light? Just because it is what plants evovled under, doesnt automatically make it better.
Sun isn't actually the best light, like outside nature aren't the perfect growing condition
Yep years ago I got a batch if GG4 from a shop and out of habit looked at the numbers and the guy knew I was going to pass because it said 16% THC but 6+% terps and I was going to pass but guy stopped me and forced some terp talk on me best weed I've ever smoked opened my eyes to terps baby.
I bought the first 650rs that came out and I bought the UVA bars as soon as they were available I did notice quite a big difference on a few strains just for knowledge though I have upgraded to optic LED bar style lights which are way better I get way better yields and they also offer UV bars which I will be picking up here very soon
UV leds aren't efficient enough go with neon tubes
i just got roots in 6 days with my turbo klone. not huge roots, i wouldn’t transplant them to coco yet, but most def roots. 9 days in all 40 clones have 4-9 in roots ant a lot of roots on each clone
18 v 24 hours? What's the DLI? I think you should let them sleep. You can give the same photons per day with 18 as 24. You'll get to a point where you're burning them before that's not true.
Great point
my growers choice light has uv bars can buy 120$us
I’m a fan of all them FANS doodle!
🎉DGC!
The studies I've read show an increase of SOME terpines with the addition of UV light, but it always seems to be a trade off with decreased levels of other terpines.
Once again sunlight shines supreme
Hand watering is such a pain in the ass when you like variety. I’m finally gonna be automated once I get these seedlings established, no more sacrificing sleep to stay up chasing a bunch of 1 gallon pots with water come mid flower. 😂 Swtg it’s a good thing I’m a disabled vet with no responsibilities or id have needed to figure out auto watering a long time ago.
Ac infinity has a 4 bar uv light system for a pretty reasonable price. Not sponsored but i want one from Santa
Hellos. Managed to pick one of them sets up before realizing they’re UV-A pretty which helps with stretch only and not the terpene increase necessarily like the UV-B do.
@@alexaliwarlock i didn't realize that Thanks for the info. Have you ran it yet? I was wondering if you think it would help with getting more dense buds under my canopy?
@@Kolten82217 you’re welcome. Running them now since week 3 of flower and in week 7 at the moment and buds seem to be starting to bulk up but things still seem on par with my previous run of this cultivar. Will be able to see if it stops the stretch more next run because I didn’t have them during the stretch.
@@alexaliwarlock one more question do they put off much heat? It would also be helpful in my situation to heat up my 4x4 a little. ( would much rather have it for terps) but dang thats a bummer i really wanted one to mess around with uv and terps lol
Excellent question, according to my stats, during the time they’re on currently (4hrs), they slowly increase temps 1.5 degrees •Canadian (•C lol)
+1 on the advice guys.
Scotty says he would choose uvb over uva? Thing is even like ppfd and spectrum the pheno and selection of strain using higher ppfd or uv def is pheno selected and many this add on wouldn’t be helpful.
I was growing indoor .and my wife and daughter complain about smell . so i move my stuff out side . and the terps change on the flower out side it was more sweet out side for some reason . all my friends agree the out door product tasted more sweet just bag appeal was not as good as indoor . I grow in Hawaii
Grambo!!!😂 Overgrow😂🤣
I have 2 UV lights. One is mars hydro UR45 & hlg 30w uva. I don't use them much but I do some.
Looks like my buddy Marvin from the Philippines
I hate hand watering. I have switched to wicking systems. I only have 2-5 max growing so I can still give each plant the time and care it needs
Love dude's new pipe👍
The best!🤣💯
I just added some uv b
Exacto knife.. especially for fimmimg
Gd’afternoon, what are your CO2 PPm levels…?
DGC always bringing the knowledge 🤘
Fact check cause too much I see major issues and the hosts not knowing the most common info. It’s not like this is live.. come on
Cringe
Thx for the content guys...cheers, thx for sharing.,,☮
Has anyone else notice that addition of uv light adds color to plants?
I have seen it. Just dont push too much. A little bit seems to add some color to some cultivars. However trying to add too much can burn. and when we are seeing this color change, we are most likely already walking the fine line between stress and burn as it is.
I never noticed that. Been using for years too. I think its more the strains your working with.
Idk could’ve been stress or a dry back or something idk but looked cool grown this strain 4 times now, not sure?
@@johnboykin3128I believe the higher Kelvin Temperature Diodes 5K/6K, which have more Blue light, and less Red, also have some UV output, just below 400nm. This could help with Fall colors. I think just having more Blue light, during the last weeks of flowering, can also promote this, as well as extra Trichomes..?!
Some grow lights have this option(and many other options), and some people used to use MH's for the last 2-3 wks, after using HPS for most of flowering. There are definite advantages for "Cool" colors.
If I wasn't so "foggy headed", right now, I'd have a clearer answer, or a specific product to point to..🤔👍💯✌️
I've been growing for 29 years and my clones will always pop roots in about 5 to 7 days.Yet will any lemon cuts I have waited up to 21 days for roots before they grew out.
I really want to try to recharge and grow a dot. I am disabled because of a brain tumor. Is it easy like you say.
Migrow guy says white led have enough uv and red and green and blue thus not needing extra uv or ir fixtures. Just wondering
I heard Alex hardy was saying blue lights to keep canopy height down a bit more I’m going to give it a try some time probably with the next run
Don't forget to like and subscribe guys
Thank god Ricky Bobby showed up and elevated the show
Wow! Look at Ricky BOBBY!!!! We need a raffle prize to meet him! Great looking dog - HAHA! :D
Have none of the hosts read about LED lights??? They do produce IR light... just look at the chart that comes with your light that shows how much wavelength you get. It would be nice if these guys learned about stuff before talking.
Pretty easy to do. Makes me wonder sometimes.
I run the infrared for ten minutes to fifteen minutes before lights on in the morning and ten to fifteen minutes Every morning before lights on all through cflower and veg
Tekno Viking just wants to dance, Dark Santa ain't got no time for that, Chuck by default.
As it should be.
😅💯💯
you don’t use uvc for growing 😂, come on how many times does hlg and google gotta tell ya uva and ir are in led’s but if you want uvb it’s a fluorescent . hlg recommends to use their uva once you see buds forming aka 2nd weekish of bloom running it full bloom on/off vs uvb is last 2-3 weeks before Chop at .5hr-2hrs
Uvb would be a better choice for thc...not sure about uva
I have a 5x5 gorilla tent I rip the tent by falling in. I call gorilla and they have no replacement for it. Is there no name piece for gorilla tent. The middle part of the skirt. We're all the zip
My clones get 24 hour light
Yup, uv basically a 30% increase of total cannabinoids over all i thing guys, keep rocking it 👍 😊
Yeh but if you only turn uv on for 1 maybe 2hours before lights out it really helps with trichomes & terps buddy
& that's from week 5 to end m8
4 tents is perfect for 12 plants perpetual harvests, 2 - 5x5 and 2 - 3x3 wish we had room for a 10x10 lol
Yo I tried signing up for a new account on the website and it's demanding an invite code. Wth
Tons of knowledge dropped
There is IR in led
What’s up Scotty
Chuck
Spiderfarmer had a sale on their uva bars... $40 all in ... for that much why not
😂😂😂great episode guys🤘✌️
