5 MISTAKES New Growers Make with LED Grow Lights 

Mars is awesome, first try growing indoors i got the TSL2000 tent setup this september, im trimming tasty nugs as we speak. common sense and good seeds is the main thing

Better you use DLI to adjust distance. And you are 100% right about mars hydro they a good lights i use viparspectra XS 1500 and thé p1000 and thé results are amazing.

Mars-hydro are very affordable but they are far from being cheap . And they have a good reputation from consumers. I have the Mars-hydro T-2000 and I’m very satisfied with its performance. I’ve noticed there are a few designer lights out there that are way overpriced but I’d rather stay with what is proven to be effective.

You cheapo like this guy said don't buy cheap lights fool 😂

Hey there i also have 2 ts600 from mars hydro what height do you set them at for optimal growth

Snap and Mars hydros customer service Is terrible

I've never had an issue with mars hydro lights even my very first mars light is still going strong no problems just fatty nugs.

Am 6 weeks into veg will it be ok to change form 18 hrs to 24 mid veg ?

​@Blazeproudman I've done it before with no problems but I vegged for 2 weeks after. Maybe it could shock them if you only do a few days then switch to 12.

@@Blazeproudman I always give my kit a couple of hours rest but give the autos 22hrs all the way through.18 to 24 wouldn't be a problem but I'd make it 22hrs.

25% for seedlings ? i am having problems with seedlings stunting or just stopping after the first set of leaves but ive got my xs1000 at 70% ....can they get too much light in the first 2 weeks?

​@@NOT_SURE.. Yes. Seedlings need less light because they're developing roots.

@@HLBNZ could too much led light cause them to go into shock ? IF i do get one to grow its stunted all the way through, Im trying some proper high grade seeds and root juice

Glad it was helpful!

UV light intensity does not get messured with PPFD / PAR Meters. Just a "good to know"

@@anneStrackRheinmetall I only run the uv 1 hour a day in flower

​@@anneStrackRheinmetallIf the meter has an ePAR setting, for "extended PAR", I know they detect IR, and I'm pretty sure any UVA/UVB, that plants can use for photosynthesis. Just learned about this from a very recent MIGRO Channel episode. Shane interviews Bruce Bugbee, creator/owner of Apogee Instruments, who explains his newest Meter, with ePAR and more. Mr Bugbee is popularly known as a scientist, doing space farming with NASA, and at Utah State University, where he's The Director of The Crop Physiology Laboratory. And what crop? Hemp, of course! He's been working with low THC plants for several years, now, and always in a controlled environment. He was getting funding from NASA only, but now it's half NASA, half Cannabis people. It's a really great interview, and within the last week, I believe..?! MIGRO Channel's Home page under "videos", and should show up near the top of the list. Highly recommended when you have the time.👍💯🙏✌️

And yes the autos were finished about 10 days before the photos but they did have about 2 weeks of flowering head start on photos cause they take 14 to show Sex

I grow them together too. But I flip to flower when the autos are done that way they get hours of light, which means bigger yields. And you get a mini harvest to enjoy while you wait for the photos to finish.

I recommend any fixture using only Samsung lm301h EVO diodes 3500°K is the best yielders! 6x6 = 36 x 30w = 1080w...18 x 60w QB's = 1400/1500$ delivery included! Maybe you live in a very cold area that's why you still want to use this old tech who produces more heat than light intensity... I started indoor in 2005 with T5 or T9 can't remember then I tried 250w hps 400w 600w mh fluo almost everything except convection (like a round fluo half white half blue/purple)...and in 2014 I made thanks to the DIY led community on rollitup my first Cree cobs cxb3590 CD @1400mA fixture that still works well I made more for me and some friends then I switched to the first iteration of the QB's then the one with lm301b now I have some lm301h and I plan on building a 10x10 with Samsung lm301h EVO 60w QB's 3500°K nothing else...I keep notes of every run I make since 2007 so I know when I increase my dry weight since everything else is the same when I change 1 thing in my grow I will be able to notice...at the end of my hps period I was able to pull 0,7/0,8gp (no a/c no co2 organic since 2013 and living soil since 2016!)when I switched to led first run quick veg I pulled 1,3gpw and after 1,4gpw on average the next fixture brought me to 1,5gpw next 1,6gpw and actually I pull 1,7/1,8gpw on average...I want to be able to pull 2gpw on average when I will get the new EVO diodes...I heard people are pulling almost 3gpw 2,7 exactly with those diodes a/c co2 the right clones coco coir and heavy feeding...when I started outdoor in 1997 1gpw indoor was an urban legend even early 2000 and now newbies are able to do it first grow with LEDs... And you will have to change bulbs every year or 1.5 year same with the reflector 3 or 4 years max with this heat...when underpowered LEDs last 10+ years...I will use those 60w QB's at 30w...yes I will have 100 panels in the 10x10😊 Have a lifted one and lots of good vibes from France growers family

If i can find the study again ill send it but potency decreases a lot after 48hours of darkness. You are better off with 12/12 or 24hours of light to finish with, and if you want to increase your yield do your first 4 weeks of flower as 14on/10off

@@evzevz06 That makes so much sense , Once they are triggered to flower it's ingrained , so pushing the day length a little can only result in more material , but too much more for too long will 'untrigger ' them and make veg th priority :)

Lol hu? I can't even get past your first line.. 4 quantum board 648 boards. Wtf dude. This isn't as complex as u dorks try to make it

If its just one plant, then a cheap 80-100w LED should work just fine for the first weeks and months. If you Just need an extra light in your Greenhouse as an additional light source to the sun, then a 100w LED will be enough to support larger plants

Or you just research the best light for ur space

i think there is a lot more info about today, when i started not a massive amount of info about & agree do some research ..@@Jaccson121

It is the ThinkGrow Model-H: www.ledgrowlightsdepot.com/products/thinkgrow-led-model-h-grow-light

Leaf surface temperatures is a problem with led lights. How energy efficient are they if you heat your grow space to 85 to get a leaf temp of 75? Most people are not thinking about leaf surface temps and VPD. Black Dog LED and Kind LED recommend ambient room temp of 85 but Spider Farm recommends room temp of 75. I’m not sure how well known this problem is. Hopefully this will be debunked or they’ll start designing led lights that can heat the leaf surface better

Eww

I ordered Aglex k2000 for around 155 dollars still waiting and i m very excited

what's the difference between full spectrum and white?

Just white doesn't have the red and blue that full spectrum has .​@@exshenanigan2333

Full spectrum with alot of red

@@andreabc1469 what's the difference between a white light and a full spectrum light?

Lots of red for flowering

I have an Electric Sky, and I'm using it right now, only on its 5th grow. Did you notice the part on this video where he says too much red and far red in the spectrum can lead to stretching? Right when he says that, an image of the ES 300 spectrum appears! It's the exact image I have of a screen shot I took from the Green Sunshine Company website before they went out of business, and guess what? I've been having issues with stretchy seedlings, even after adjusting the ppfd. Temps, humidity, soil, watering etc. all in proper range, but still some bad leggy stretching. yet not all strains stretched. Looking at Migro lights right now, also ThinkGrow and Grandmaster LEDs.

@@Rohmtschen stretching???? Give me your email I'll send you pics...your doing something terribly wrong...I have the TIGHTEST stacked nodes POSSIBLE..DO NOT USE THE STUPID guide Electric Sky used on the knob...it's a joke...I have ot cranked at 30 inches...and have 9 inch buds ..

@@Rohmtschen migro doesn't compare to ES I have both...your comparing an anus to a vagina..both holes but one stinks

I highly recommend the vipraspecta P2000 for 199.99 you can't go wrong, I've been running it for my last 3 shows and have had amazing results

HLG 325 Max for 3x3x6 amazing results for me. Very Happy.

Wrong. The correct ppfd can be achieved by having the light at the proper distance

@@warriorxtman2 In my grows with limited height a dimmer makes things much easier. In a perfect world a dimmer is not needed but it sure makes things easier. Sometimes you get a stretcher that gets too close to the lights, dim or burn your choice...

@@warriorxtman2 Can be achieved, but not under all circumstances. Even light distribution can be very important.

I am running in $20 Harbor freight grow light with no issues. I have a short posted on youtube feel free to watch.

Yes mate they are a very good brand, possibly the best. Ive got the lumatek zeus pro 600w 2.7, its an animal of a light ! I would be very careful with the intenstity of these lights though. Ive also found that hanging height should be almost double what the manufacturer states. Start it off using only 25% power and hang at about 100 - 120cm from seedlings. As the seedlings get bigger over a week or 2, lower the lights down to about 60 - 50cm still at 25% power. Keep the lights at about 50 - 40cm hanging height at 25% power for atleast another couple of weeks of veg, until they get bigger. Then you can bump the power up to 50% but start hanging the light from about 80cm above canopy and let the vegging plant grow into the lights but just be very careful and watch out for light bleeching and red streaks on stems from too much light. You will never need to go more than 50% power throughout veg and could probably get away with only using 25% throughout veg but you’d have to drop the lights to about 30 - 40cm from canopy. Im not sure the penetration potential would be that good at 25% though so like i said, after a week or 2 into veg, bump up to 50%. My lights are currently at 70cm in veg and are thriving. I started them at 80cm and they have grown 10cm already into the light. Im keeping a close eye on the plants for any bleeching now. When you are ready to flip to flower, id still keep the lights on 50% but lower the lights to the canopy where its comfortable. At this stage you will probably be hanging them around 60 - 50cm, maybe lower if the plants will take it. Then when the buds form after about 3 - 4 weeks of flower, i bump the lights to 75% power and raise the lights about 80cm from top of canopy to start with. If the plants still look good then lower slightly until you feel they are in their prime. You will only then turn the lights to 100% for the last 2 weeks of flower but be extremely careful as these lights at full power can easily burn the plants. Most importantly, keep the humidity levels at 65 - 70% from seed, all the way up until week 2 of flower, then lower it week by week, 65%, 60%, 55%, 50%, 45%, 40% ( final week of flower ) hope this helps 👍🏼

There are too many amps on the circuit. You will need to plug something into another electrical circuit in your home.

@@Ledgrowlightsdepot I think it was a bad circuit/fuse in the appliance. The faulty piece in the fridge was replaced. And no issues as of the moment. Also, the fridge would short without (both) the light OR space heater on.

depends entirely what you are growing.. If you are growing lettuce the shop lights are fine but if you plan to have any fruiting or flowering plants [such as cannabis] the shop light will do fuck all.

that fine for clones and veg, but if you plan to flower anything under 100w you are better of smoking your lawn mate.

@@Mikael-jt1hk haha you must not know shit about growing I got some amazing Frosty dank buds going under my TS600 it's all about skills & Nutrients

Great thought! From what I've heard our eyes can pick up green the easiest allowing us to use a much lower light intensity and still be comfortable. Let us know if there is any research showing where they things would cross over, that would be great! :D

Green is reflected and not absorbed by the plant so it doesn’t matter if it goes deeper .

@@sicuro5050 it actually by some degree Penetrates straight through the leaf structure & out the other side & science has proven plants Do use the green spectrum 🌱👀

@@sicuro5050 this. otherwise, the plants wouldn't look green, but black instead.

do you want it to stretch? If not, I would flower with a veg light for the first week. Also, I've had success with 24 hours of darkness before starting the 12/12 cycle to jumpstart the flowering

@@ModMax69 I'm trying out a MH FC3000 LED. My experience comes from indica, super soils, and uninhibited space going into a tiny tent with sativas; hoping FFOF doesn't burn them up.. My aim is to minimize stretch without the light burning them up, too.

gotta scrog, my dawg!

unless you're growing in a sealed room, co2 "boosts" only "boost" your cost.

@@ModMax69 nah all depends on what you doing, i just top a few times and with the help of a clone tent to get a head start i get just over an oz a week on avg using a 300 watt.there is no right or wrong or gotta anything.

I agree with everything you except cannabis having a roof. I've had different pheno take and use different ppfd . I have pheno that can take all 2200 ppfd. Remember a good de hps can put out 2300 ppfd and I still use those in the winter. There is no one size fits all ppfd.

if you are using led you might be missing out with one giant cola but I feel you. flat canopy has worked for me @@mvsmvs8428

Yes, but you can give them some rest. It might not be beneficial with 24/0. 20/4 is possible too.

@@suki4410 plants are not humans. They dont need ''rest'' 🤣🤡

My plants grow the most during the dark phase. Every morning I check they explode. They don't grow that much during day time

@@Mikael-jt1hk Like any living being, they do need rest.

@@Mikael-jt1hk every living thing benefits from a rest 💚

Same just to insure I don’t have herms going into flower. I’ve done this for 16 years

💯 bro theres so many kooks out there like the guy on this channel talking bs like they know better, look at his vid its all copy paste nothing he's grown himself major red flag 😂

This is wrong. LEDs are duble as efficient as high pressure sodium lights! LED have two times more light with the same wattage, or you can use less watt with the same amount of light.

All you have to do is simple math to prove you wrong 😂

you are very right, the biggest factor missing in LED in my eyes is the infrared heat. If you compare HPS and LED side by side, plants under HPS look slightly bigger and the internodium is slightly longer. I have seen top LED lights in perfect environment not producing more per watt than HPS. Big industrial growers still use HPS why should they if LED is better? For me the only good argument is if you have a heat problem and you're enclosure gets above 28°C (82,4°F).

​@@suki4410leds don't produce as good a bud as Hps and MH and CMH. Leds aren't great atol.

@@eddiehayes5608 in veg I run 24 hours. In Budd 12/12

I used 8 dif brand/model of leds over past 7 yearz and as long as PPFD is on point they do just as good under Chinese LEDs as Samsungs just get a little more light with 301b/h which costs more $. I bought a hundred lights I might care but not just a few also I've had expensive lights break just like cheap ones ironically some of my cheap lights never had problems

@@Mike-ms6he I'll check it out, thank you!

I agree with the altered cycle. 12/12 is speaking in generalities. We will need a whole other video about plant light/dark cycles.

exactly

But like you said you don't need as many watts to achieve same photon output. I unfortunately learned this starting off thinking my LEDs would be cool in the tent lol, but getting a better light with a detached ballast does help

More light = less heat.

You dont know, what efficency is. LEDs are more efficient and have less heat.

@@suki4410 you don't understand what your reading, 1000w of LEDs output same heat as 1000w of metal halide or high pressure sodium. The difference is the light output from said 1000w being greater from an LED so yes more efficient per watt

​@@nordicwarrior9566 This is just wrong dude.. So for example: 1000w (Input) LED produces - 100w of heat - 900w of light While the old 1000w ones would produce - 200w heat - 800w light So yeah. LEDs ARE cooler

I like the new light it's not led not hps its cald sun on demand think it made in Switzerland lol $6000 to much money for this guy. check it out mate

Hadn't heard of that one yet. A few years back I seen a plasma fixture with great claims. They were selling for 1300. Was too high for me also. Hps fixtures for me until I die. Mostly because I've got so many and good supply of bulbs. At 240 volt the power cost is very important to curb cost throughout the grow. Grow on brother.

Yes theres drop off from leds. Not enough to negate the better overwll efficiiency wnd efficacy

no you won't.....and that's fact now.

@@newlife956 how long have you used led to compare to high pressure sodium? I have over 20 years growing experience, even used 1,500 w metal halide.

You're not going to win this argument....as LED is more efficient with a much better spectrum. Those are FACTS, not my opinion. I've been growing cannabis for almost 40 years...and I used to use MH AND HPS....but when I switched to LED my yield and potency went way up. Here's another fact....across the board on all strains, LED increases potency 20% on average. LED has surpassed HPS....and you are behind the times now.@@MissionaryForMexico

Yes i think so

Run side by side 200 watt vipar spectra 1000 watt hos and mh not much different

Don't you like how nobody seems to share your sentiment?

This was a simple was of saying that it is not beneficial, and actually detrimental, to give plants 24 hours of light. They require a dark period. I have a degree in biology with a focus in plant ecology :)

@@Ledgrowlightsdepot then maybe your school should have covered how some plants require a dark period and others don't. Cannabis/marijuana does not. This is one of the most basic things about cannabis cultivation so it's astounding you pretend to be an authority. There is no detriment to using 24 hour light cycles as long you dial in the DLI correctly. Do you even know what things like dli or vpd are?

@@bakedveal2624 except for everyone who has ever grown marijuana or studied it. Most of this channels viewers are probly 12 year olds like you who don't know better yet
