Double Your Harvests By Doing THIS with Your Grow Lights 

so as someone who went to college for agriculture when you start to dial up the lights around 1000 or more ppfd the only way it will harm the plants is if they are too close to the lights you always wanna stay 11 in. or more away to be safe. the big issue people have is that when you have higher intensity light the plant is breathing and uptaking more nutrients so you can get fertilizer burn. you have to keep that vpd at those precise numbers as well. you typically dont need to add much c02 till around 800 ppfd. they have done studies where they have gotten the plant at 60 DLI.

Scott your the best love ya man great info tonite I'm 70 years old and learn from you everytime Been growing since 1979

Scotty really is the Billy Mays of the grow world.

I know the show is geared more towards beginner growers, but youre enjoyment talking about growing helps me do max reps in the trim gym

Scotty brings a very good point about progressive lighting schedules. New growers think more is always better when in reality less is more

I really appreciate those who share their hard-earned, valuable, interesting knowledge with others. Thanx!

Love these little vids, great job Scotty and Hi-C.

they key and ive tried everything is to let your plants grow up into the light vs dimming.. get your plants as far away as possible from the light without them stretching , "but leave some room to move up the lights for stretch" and as they get older/taller they need more light which is perfect bcuz as it gets taller it gets closer to the light so its a ying and yang scenario.. just before flowering move lights up 5-10 inches and they will stretch into the lights perfectly!

If you keep your leaf temps below 86°f , you can hammer them with light without the need of c02. I can push my plants with close to 60dli from flip to harvest as long as the leaf temps stay close to 80°(78° being ideal) but your VPD has to be spot on. There's a study that was published by the NIH a few years back where they could run 2000+ ppfd with no need for c02 due to keeping leaf temps ideal. I've been doing that since and my yields ,bud density , and trich coverage went through the roof. Lol.

JFTR: I started my plants at 350ppfd, at day 5-7 I went up to 500ppfd, from day 12-14 I went to 650ppfd. Planing to go up to 1.100 from week 3 flower. Till now, they look fantastic and grow amazingly fast, compared to many RU-vidrs. I'd say, all good so far 😎

I have a mars hydro fc-e4800 480w bar style led. I keep it at the top of the tent at 100% all the time. During the last weeks of flower, I turn it down to 75%. My seedlings stay short and robust. When they flower, they can stretch up to 18" away from the light without burn. I have also started keeping them at 80-87F 60-80% RH during the first 3 weeks of flower.

before maxing out my light in bloom i wait till they harden they seem to be able to handle the max power at that point before that when there in early bloom still growing etc the plants are the same as veg till they harden 20% when babies,then i go to 30 early veg to 60% end of veg then 70% at start of bloom then around a week n half into bloom straight from 70% to 100% using the AC infinity 400w light and the uv lights and the rest of there gear lol for abit of context

Ive got a new AC Infinity Evo 8 which has the new samsung evo diodes . Its 720 watts & i use it in my 5x5 & im still yet to turn it up past 7 which is about 600w as its too bright . the new evo diodes are super efficient which is great as it is saving us bucks on our electric bill & the light is not being used at full power so that has got to b a good thing . biggest harvests & best best buds ive had but with less power 😎

Same here 200 to 400 PPFD for clones. 600 to 800 veg. Higher in flower usually 900 to 1000.

Scotty cool, knowledgeable and on the pulse of everything growing!

Some seasons ive grow with led some ive grow with DEHPS For me DEHPS is still KING 🤴

I havs been having really good success with my hlg 350r's above and 100 watt lead bars on the sides. When looking at the bud you can tell what side the side lighting was on. The buds bulk out more on the sides with ligjts

Ive been growing in aeroponics for about 7 years and growing for 23 years in some sort of hydro . I've had a few strains stretch to the lights and taken 1700 1800 ppfd. Gg4 is one that loves lights . Then there are some that can't take it chem 91 likes less light. It's strain and pheno dependant really. I have a handful of sp6500s I use for flower and a few fc6500s for veg. I love the sp serries lights. I used 1000w double ended mg / hps before that and still do in the dead of winter for veg. The best thing to do is turn your plant into a bush an use all your space . Snip them young . I use lst clips personally and have the plants grow out rather than up this way most the plant gets all the light I dislike trimming 70% of my plant worrying about larf.

LEDs are very different to HID lamps.The stretch is down to the spectrum more than anything. Iv been using LEDs for a few yrs now but I still have my bulbs from my HID lamp. Metal Halide for veg as blue stops the stretching and sodium for flower as the reds in the spectrum induces stretching. The reason why my Optic 8+ has dials for warm white/veg and the flower dial has more reds in.It also has a resin boost dial that turns on the UV.

Big tip for going up on your light if you can and alot of lights are 25% incerments turn up 15 20 mins at a time and see how they react leaves will fold down and try to hide from the light if to intense just have to slowly work them into the next lv of intensity

The law of minimum states that growth is dictated NOT by the total available resources but by the most scarce recourse, better or more lights alone won't make a difference unless everything is dialed in

scotty!! I got 2 hlg 650r in a 5x5 crushing it with autos!! 1400 ppm co2 and 1400 ppfd ! you have to feed heavy also with this intense set up ! thanks for your videos ! keep crushing it blueberry bill from PA

im doing incredibly well with 8 household leds 14 w each and 6 of them are 4000-4500k and 2 of them 6500k total of 112w for a 2x2

You said to let you know in the comments well I just went into flower 4 days ago. I'm growing critical runtz which is pretty Mediterranean oriented loves full sun and high heat. I'm pushing 1500 ppfd right now having some really nice results at 14 in away from my canopy. Oh! Dude thanks for letting me know about the photon app. Its pretty good like you said

Just got a new light today now l feel good l don’t have that crappy light anymore as weeks go by in different stages l increase it 25 percent at a time l believe that will be the key as Scotty says l will find out after this grow

I have the HLG 320 r and gave my plants heat stroke it was only at 50%. Leaves curled, but was able to pull off the harvest. Light is your best friend or worse enemy. Get your lights dialed in

Lol I did the same thing got an HLG scorpion diablo went fine through seedling and veg stage but I cranked it up as it started flowering and poof crunchy crumbly leaves but its a learning curve for me Ive never grown inside or an autoflower plant and still havent blahaha live and learn and I damn sure wont make THAT mistake again probly others but not that. Love the show thanks for the insight and tips. May you and yours be blessed.

Just my personal preference, I use a mars hydro product. Barely go above 50%/75%. Most of the hybrids can’t take the higher light intensity and if they do, they’re far and few in between and you can’t sacrifice the whole tent for one or two plants. Genetics plays a huge role in anything you grow, if you do a mixed/grow like I do, multiple strains. it’s really tough to nail it down 💯 %

Scotty, I’d love to see a video of you explaining staking a plant.

Your a CHAMP Scotty as always son keep em coming.

I use chilled 330 and have never gone past 75% 🤘✌️THANKS SCOTTY…Most will only need 800 to 900 par as we arent running co2🤘🤘✌️✌️

Just started watching your videos....,! I've learned more in the 3 that I've watched than a large number of the other 😉🤙and I didn't have to go to another site pay money, thanks dude ! Recommending to all my friends. 😂😊

wow I bruned the hell out of plants with HEAT from HPS back in the day. So you saying LEd can burn with light. WOW. Its so advanced now. Ive been under a rock for 20 years

Face-8000 in a 4x4 6.6’ tall 15” pots light at the very top.starting flower I’m at 75% about 3.5’ away from the canopy for the 1st and 2nd week I will actually slowly turn it down as the plants grow to maintain ppfd .then slowly ramp it back to about 80% week 3-8

loving theses real growers shorts thanks skotty and hiC

Viparspectra pro series are next level 👌 💯 🔥

Good stuff!!!

Very simple with lights 200 watts or less power keep 12 inch's to 20 inch to the tops no closer and anything over 200 watts be very very carful ;)

Accidentally hit thumb down but I love yall and respect.

Amazing video and knowledge. I've burnt a few with too much light not everyone talking about this

Just started a run with my brand new hlg 350 Diablo. I had 2 hlg 100’s but this 350 is insanely powerful. I had to bite the bullet and buy some method seven glasses too bright for my lookers.

I’m using the same lights and I keep mine at about 33-35 inches above canopy. Light intensity drops off hard on the edges of the lights but it allows you to turn up the light for slightly larger coverage. If running only a few plants I’d go from 25-30 inches and dial back quite a bit on the knob.

I’m rocking 1100 par in flower at the finish. Somewhere around 2-3lbs of finished per light. I’m using fluence spyders for one room and Phillips LEDs in the other. Phillips spectrum seems to pop those colors out a bit better than the fluence.

Bro I'm buying a par meter too man I'm in the same boat I have tacoed some leaves this round because my plants got too close to the powerful light. I dimmed them back and raised the lights as high as I can get them . Lmfao powerful lights are a trip . I've had mine for a few years now and I'm still trying to master them. Like you said tho when you've got different cultivars in the same space and same canopy height you really notice the plants that love tons of light and one that could have done with much less light. Happy growing!

I’m glad Alex Jones finally found something constructive to talk about. If you have worries, get a 1000 watt HID and wait a few more years for diodes to catch up.

Just bought Viparspectra P2500 , learning as well 👍✌️💨

I’m on my first grow ever. Running dwc. Learning dwc has been a crazy adventure so far because I’ve been cramming as much knowledge as my brain can handle on a daily basis to keep my plants happy. I started with a clone and germinated 2 seeds, 1 being an auto flower. I also ended up taking 2 clones off my first clone just to practice and now I have 5 plants in flower on my first grow and they’re praying all day everyday. Very happy plants so far, but they each have their own scars from the learning process. But anyways my oldest plant, the first clone I got, is on day 39 of flower and I’ve been pushing 1,200-1,400 ppfd (measured with Photone app) across the canopy the whole time and have had no issues. I’ve also ended up pushing the ec up to 2.6 without getting burnt tips. Running gh trio off de chlorinated tap water. I’m not running co2 but want to. Based on my readings (water ph, ec, ppm and intake. Also watching leaves for indications) the plant kept asking for more and more and I kept giving it until everything leveled out and she’s been incredibly happy with very high ppfd and ec.

Simple measure my ppf at different levels as the plant grow and I raise the lights. keeping them in the correct ppf

And Ty again, guys you are great!🎉

I'm using spider farmer SE 7000 in my 4x4 in 5 gallons it's 2024 model just got the light im in week 5 veg 23 inches away

Plants don't consume plant nutrients...plants consume the waste products created by all the micro organisms that live in the soil or medium, and in return the plant itself produces a type of sugar based attractant that keeps the micro organisms in the root ball area to keep on providing the actual food that ALL PLANTS actually consume ( and always have) . This symbiotic relationship has always existed since our creator put all plants and trees onto our Earth. Way back when there were NO NUTRIENTS available anywhere because there were no shops that existed. All plants and trees have always survived with no help from mankind . Plant nutrients are made for people who don't understand what a plant needs to grow so they go to the local plant store to pay large amounts of money to buy products that no plant has ever required. People have a range of foods at home to feed plants but the plants cannot consume it until it is the correct form to be digested by any plant through its roots. Anything that can be eaten by any plant must first be consumed by micro organisms in the soil or medium. The waste that is excreted from the micro organism is the PLANT AVAILABLE product for consumption by the plant. Simplicity itself for anyone to make using food from home instead of using Salt laden chemical based foods that always cause plant issues if to much or too little is used. The reason shop bought foods always cause issues is because the grower never knows for certain when a plant has fully consumed the LAST feed it was given before the next one comes along...and when salt laden chemical based foods sit around uneaten in the root ball they always cause issues the next time you feed your plant because often you may be adding food to a plant that does not need it at that time and this situation creates a toxic chemical imbalance around the root ball. You have all seen this happening , be it a leaf deficiency or and excess issue , you always get them. Making your own natural organic veg or bloom feeds is a better way to go and cheaper too , plus you just don't get those deficiency issues using all the natural items available to you. Natural home made foods are for the micro organisms to digest first , and you will rarely have left overs in the root ball because a healthy root ball runs millions of these unseen critters who just eat ,shit ,and multiply every 20 mins every day , and when the food supply is exhausted the micro organisms will become dormant until the next feed for them arrives . Natural home made plant foods do not burn roots or rot them. Those who know this usually never go back to the shop bought expensive crap. Of course , if you are a lazy person you won't want to make your own foods, after all YOU don't have to eat them. Good returns come naturally for those who put the effort in and seek a better return by giving the plants what it craves.

Man I'm Still rocking those blurple lights buddy they work pretty good but I definitely need to get me an upgrade sometime what I really need to do is win some😂

I'm running 2 HLG 350r Diablo in a 4x4 area. In seedling and early stages I run about 50% with them raised as high as they'll go, about 5.5ft. Then in veg I crank them fully up 100%. I'm doing dwc, and I create the most awesome short stocky plants. I start topping when the are very small, no training or tied over, they have the shortest stoutest branches, totally amazing. No light burn, huge thick dense bud formation!

Set led high percentage, than led height to be 600 at plant canopy and flip to flower. Adjust after stretch to 1000-1200

Lol its my first time growing rocking a 2x2x4 with a 100 watt things are going well one auto in flower one norm in veg

Im still using Lec but i start with 145w for grow, next i put it on 215w for pre flower and advance flower i finish with 315w and i add a Led

I have a cheap unit ~t from ebay. Its just a light intensity meter, very cheap but just keeps up from going overboard with the light.

I run my lights for veg at 25-30%, then for flower the maximum I go is about 60% which works out give or take 1200 PPFD

my ppfd is always over 1200 i grow in living soil and my room is always hot, and my pants dont get fried. they take it, and make huge nugs. also i have a fritter little taking 2200 ppfd and pretty uch cruising along likr normal. leaves do look a little wonkey but not much at all. i was amazing when i took the reading... so high and she is taking it in pre flower even.

Loving the videos I enjoy the show but getting extra Scotty talking is always a plus and u are laying down some good info

Scotty, BLINK man !!

I'm running a Photon Tek X600WPro bar style light, keeping it in a 5 x 5 tent at 7' max interior space. The light is 36" from the canopy and I'm getting minor light burn on leaf tips at 50% power.

been looking at including the migro UVB lights and mars hydro IR and deep red lights, starts making the lighting schedule complicated

Learn and burn. Scotty.Cheers

Love this content.

the par apps work really good..and free

I just got a new light the other day and cooked 2 of my plants. Oh well live and learn

I use the photon app and get to 1000 ppfd but that's middle flower. First week of flower is 650 ppfd. I also use their PPFD calculator and try to stay around there you add about 50 ppfd per week of flower until you're at about 1000 then start dropping it back for the last two weeks.. I calibrated the photon app using the ppfd maps provided by my light company

Super Information danke

cant turn my lights past 75% makes my temps to high in a 2x4 with my fans on full blast ladies didnt like 100% at 85 dagrees in late flower which brings me to a question is 85 dagrees to hi in flower is that strain dapendent

what up Scotty, much love gro bro......sub

I make sure my light stresses them a touch so i know they are maxed out

Some great info here, thanks for the tips

I’ve gone as far as 1500ppfd with 2k co2, and following vpd around 80 degrees.

In my 4x4 i have 1 electric sky es300 and a mars hydro sp3000. I noticed the MH does better in veg and the ES does better in flower for light spectrums. The ES i can have 100% in mid flower with little to no issue but the MH i cant turn passed 80% before i start burning. Unfortunately added co2 isnt an option yet, tho my house has 3 people, 2 dogs and 4 cats. Nominal co2 in my basement should be around 500 ppms but never actually measured it

Good on ya Scotty. i wonder how often people think about the damage theyre doing to their eyes with LEDs all over the home/ work/ shops/ grows...

Hps grows the diggity dank

Almost burned my food watching and learning 😂

I just have a 150 watt LED in a 2*2 tent, can I put the light closer because its not as powerful?

Do you add IR to the light program?

I keep my 380w LED about 18-23 inches away because it gives me the full 4x4 coverage I need and I never move it, plants dont seem to stretch really but sometimes I want the stretch ;p

i run a 2ftx2ft with sf1000 only need to use 40% untill after stretch never above 80%even in full bloom fried way too many in the past too admit first 3 wks 13-19 dli veg 20-33dli flower 38-65 dli

Love your content. Keep up the awesome work.

start crop steering and see the yields go up

Good tips man thanks.👍👍

Right on! 🎉

Happy Thanksgiving Scott

So I have 3 gelato 33 and a chemdawg. They are all 10 (days: edit) out of the cloner. They are in a 2x2x4 tent with a VIVOSUN aerolight 100w the tunable with blue and UV. I introduced them at about 30%. Turning them up 10% per day. 12” from the canopy I can get to 80-85% and the gelatos are still reaching up to the light. The chem is setting nice and level. They are in 100% FF ocean forest and I give them 2 cups of water every other day. Every other watering they get a shot of photo-p and recharge. Yesterday the were showing signs of nitrogen deficiency. This seems crazy to me that they could need that much feeding and light so early. 6” inline fan on level 1 24/7. 75° and not letting humidity climb much above low 70s ever. It’s more often than not in low 60s. Are they really just that hungry for light and nutes.

That photon app is off by 2-300 ppfd compared to Apogee meter which is dead on balls accurate .. so with that kept in mind it could still be beneficial

I use phlizon pro series 2000w led in a 2x4 cant go higher than 20 on the dial as it takes it up over the temps i want but i just presumed it was because i needed a bigger tent maybe im wrong 🤔💚 buds seem to be blooming nicely this will be my first harvest so couldn't comment on final product at the moment few weeks to go 🙏💚

How do you add co2?

Lmao I jammed packed a mars hydro ts3000 bar light into my 27"×27" tent. Let's talk about some intense lighting. Had to get a extra clip on 6 inch fan just to blow on the light when it's running

A lot of good varieties like lower light levels even dialed in and they use it, the finished product seems lower quality with bigger yields

Is there a newer video about the best light set up , or does the technology keep changing too quickly to even know what's available ?

So i got a spyda farm sf1000 had it full max dimmer lux over 18k so is this why i only got ounce on my first grow besides yield i am happy it the potency and quality is top .notch .was my yield small from light is max intensity good for yeild

Vipar spectra xt 1500 , seedlings = 25% , veg = 50% , early flower = 75% , week B4 harvest 95% micro grow 2×2 😘

Great content man

Keep the videos coming

Roger that bud i have gotten 2 Mammoth LED 10 bar units over a 5x8 panda film room in the basement. Ive gotten these lights to push 1200par in this space but the Co2 levels liked to hover around 450-600ppm. Temps 85F, 55-60rh

Ya bro...
