LED lights not doing so good.

LOL user error mate. Your doing something wrong or haven't adjusted your shit, or your trying to veg with too much power and not high enough temps.

You're correct with both those recommendations. He actually had his lights at 18" for one thing, and he's been running cooler temps like you would with HID.

He said he raised them to 24" for now, so that's progress. His setup has serious potential once he dials it in, so I'm rooting for him.

initially i thought 2 600whlg over a potentially 5.9x9.5 canopy would be slim on the sides and be useless to enrich co2. so i thought turn them 90 degrees and add one to the center and that woul reach the sides a little better and provide better overall coverage, would be great to dim them

So other guys have pointed out your running too intense, but thought it was worth asking what power your running in veg, I find around 15w per square foot rocks and plants are happy.
If I go to much more than that and temps arnt like 85 degrees then I get sad light stressed plants.
Also I find if your vegging long hours you can also get the same stress, your going over your DLI and they just don't seem to like it.

You have to remember though MH vegs amazingly its very inefficient and your using a light now that in some cases puts out 3x the amount of photons (depending on the type of MH bulb)

While smashing loads of HID lights over plants works well the same doesn't apply to LED. Increasing the intensity you have to not only increase the co2 but all other parameters , root zone temp, nutrients, air temp.

I think especially in veg you should reduce your intensity, light hours and increase your temps and within a 3-6 days they will perk back up and look more like the plants your used to seeing.

Out of interest what do you pull per 5x9 canopy under your old lights?

Yeah man, im rooting for him too. I get narked sometimes when people just assume they bought shit lights.
But its understandable when someone's sunk 12k that they flip out a bit when shit doesn't look good.

Either people don't know the correct environmental differences or they don't want to believe that running higher temps or less intensity is fundemental

Personally i think "one" of the worst things that can happen to a garden is spider mites. I think it depends. anyone can grow a plant. but if your not careful or get lazy then you end up with Mold,bugs. So it depends, Are they going to, feed it right, dry it right, store it right. I imagine depending on their climate they could end up getting lucky when drying it for their first times. Or, they could ruin a house with mold and water damage, or worse die in an unintentional fire while they are asleep. In hydroponics not only do you have to get the ventilation,a/c, light right but you also have to worry about pH,ORP,EC, Water temps, microbial control. But i guess with enough money you could hire people for all of that

Ive actually built dosing pumps, pH controllers, wireless dimming modules/controller for light drivers. Timer modules that have the utmost control. Everything can be graphed over periods of time and analyzed for problems. i could literally tell when plants are ready for harvest because of the changes in ph and nutrient salt consumption. You can look and say hey they are done eating everything has flat lined for the past week

Glad you got it figured out I too bought an hlg led when they first came out and thru user error ended up hating the thing. Too low of temps and too much light. I know it was my fault but I had cmh dialed In and just went back to that for my tent. I ended up getting rid of the light but I'm thinking of getting some led to supplement my hps now that I have more room and amps.

Just thought of something else though. You should be able to dim your light mine had a screw on the power supply that you could turn to dim it, might wanna check into that. Although by raising them higher than planned you might not have to add additional lights they should have some overlap type effect.

there is a strain "bananna breath" that would show purple late late flower around harvest time. BUT it seems like its showing the purple a lot sooner under the LEDS but i maybe im trippin idk.

Im having the same problem with these HLG 550 v2s 480w in my veg. I got 2 of them to cover a 4x12 area. I hooked them to the top of the ceiling (10ft) with a little more than 30 inches space between them and the canopy.... I maxed out the dimmer to full power on both. Alot of my plants got what I think to be light bleached and some leaves taco'd here and there.

Now idk did the leaves Taco because my temps were high or because at full blast these quantum boards caused light stress? I was going up to 83F with co2 supplementation which is supposed to be more than fine in veg... right? especially since you guys say you need to bump up the temps if running LEDS for the leaves temp to go higher.

Ive since lowered it to 75-80. should i bump the temps back up and just dim these HLG quantums to 50%? theyre definitely some powerful lights that have potential. humidity fluctuates from 50-70

I was also suspected some magnesium defiency early on from these Leds so I gave them some calmag and it seemed to fix the problem. I always thought why would Leds need more calmag than HPS but thats what seemed to happen to me a few weeks ago when I first put these lights up on my babies.

also im in ebb & flow rockwool. idk if u can run temps that high with this medium

This transition from hps to led is more difficult than i anticipated

I'd raise the lights more until they can handle it, or dim it. They also do demand a little more Mg with these lights, but my guess is they can't handle that much light yet.

I must say these QB’s are bright as all outdoors.. I love my 315 and my concern was the lost of UV.. now in my 3x3 it seems like this v1 is brighter and I have to put it up just as high if not higher than the CHM.. I added a far red bulb and that’s it.. As long as I train the plant, my yield and density of the buds are on point..just had to understand that the changing of lights had a different learning curve.. I never used calmag epsom but had to use some for these lights..penetration seems good..larf gets hard too!!

If you want to get really crazy you could run both. I think my favorite setup is led with cmh. Just turn down the LED so it can be at the same height as the cmh. It's overkill for a 3x3, but it would be interesting.
