Glad to hear. I'd raise them even higher, to like 24", like I said before. The plants will probably be even happier. I underestimated the power of these things at first too. Do you have a par meter or someway to measure the intensity?Since those lights were raised they are doing allloooottttt better. They are at 20 inches and still might be doing some bleaching. Either way, the growth has exploded since then. And yes with the leds the ph raises alot faster and I'm assuming they are eating faster
Because the plants eat the acidic nutrients in the water. Similar to when the plants drinking more than eating causes the ph to go down as the nutrient solution becomes more concentrated. I'm just guessing that because the hps are not concentrating ir heat on the leafs it causes the plants to transpire less water and the ratio of nutrient uptake vs water uptake stabilizes a little moreI start out at 53" above the tray with seedlings, or clones (about 40 inches above the soil), and just let them grow to the light. About the time to flip, I'll raise them about 8 more inches, and that's about it. Why would PH rise when they are eating?
12000 I’ll be pissed too maybe to much light? Because plants loves them12 thousand dollars was spent on led lights to replace some hps light. the HLG 600W qbs. and from what i cant tell the plants grow like shit now. they dont perk up anymore. the bud development is soooo slow that u can barley even tell they are growing. ive never used leds before but i can tell the difference. and from what i can tell they are definitely not worth the investment so far. hell if i could id probably return these pos lights
I read this about 12 times, and still don't understand the logic... not being rude or anything. I just try and gather bits and pieces of information here and there.Because the plants eat the acidic nutrients in the water.

I'm wondering as well. I saw your post and was like - whoa - I was looking at pulling the trigger on a couple of these.is there anyone else in here that replaced their 1000wse hps lights with qb600 hlg lights? do you agree?
I can only say that we have 18 HLG's and love them. We've had our fair share of problems, but none light related. They are very forgiving, use alot less energy, and produce very little heat compared to HPS/MH. Results?.. See at my grow link below.I'm wondering as well.

Any current users out there???
I cant give you all the scientific facts but if your using nitrates or other chemical plants foods and they become too concentrated usually the ph will be lower. if your plants get too hot they will drink more water but they wont eat more food. if they drink all the water and dont eat the food your EC will usually go up and the ph will go down.I read this about 12 times, and still don't understand the logic... not being rude or anything.

From what I have experienced.. yes, your nutes will drop your PH in your wet mix. What your soil does with that mix, as far as buffering, is totally up to what your medium is made up of. I don't understand your logic of drinking, and eating. If your soil buffers your nute mix at the correct range, it will eat/drink. Your environment is what allows the stoma to open up and transpire, not nutes.I cant give you all the scientific facts but if your using nitrates or other chemical plants foods and they become too concentrated usually the ph will be lower. if your plants get too hot they will drink more water but they wont eat more food. if they drink all the water and dont eat the food your EC will usually go up and the ph will go down.
yes but excessive heat will cause the plants to absorb water faster than normal. this will not typically mean the drawn more nutrients from the solution. if anything it will stunt their growth and result in even less nutrient uptake when there isnt excessive heat. you have to create the buffer in your soil and you can fuck it up too, mineral salt buildup/lockout/death. i never said the nutrients open the stoma. I said excessive heat can cause your plant to drink water faster than normal and that CAN cause ur pH to go down. If you play around with the ppms your feeding at and you find that sweet spot your strains like and what they can tolerate then you can maximize everything. all that changes when your temps suddenly go up and you are feeding around max ppm for the plants and they start sucking up all the water and leaving the nutes behind. in soil nutes just lock up when it dries and causes salt buildup quick.. in hydro you have real time metering of the EC pH.From what I have experienced.. yes, your nutes will drop your PH in your wet mix.

I suppose that could be true, but there are a lot of people using a lot of different mediums, and they do react differently. IDK, I've never had a heat spike, so I can't really say I've experimented with that. We just don't run during June, July, or August,.. it's just too hot for our AC to keep up with the fresh air intake. Im going to have some mothers in there through summer tho.. but we will only be running 3-4 lights, so heat won't ...or shouldn't be a problem... I guess we'll see.yes but excessive heat will cause the plants to absorb water faster than normal. this will not typically mean the drawn more nutrients from the solution. if anything it will stunt their growth and result in even less nutrient uptake when there isnt excessive heat. you have to create the buffer in your soil and you can fuck it up too, mineral salt buildup/lockout/death. i never said the nutrients open the stoma.

The HLG 550v2, or their new R spec is rated for a 6x6 veg, 4.5x4.5 flower.what would you guys recommend for a 5x5 veg area as far as HLG i was thinking 2 320XL dimmed about halfway.
As band-aid you could have a water emitter on your outdoor ac condenser. when the compressor is running have some water carry some of the heat away from the coil. idk if that an option for you but it can really bring down the temps from the evaporator. assuming you cant just upgrade your acI suppose that could be true, but there are a lot of people using a lot of different mediums, and they do react differently.

it should have been mentioned that there is only about 1-2ft max between the light and the canopyThe HLG 550v2, or their new R spec is rated for a 6x6 veg, 4.5x4.5 flower.
