Was just thinking of supplementing with t5ho. Whats the theory on the UV towards the end of flowering?

Not sure if its because of the scrog but the buds on my 315w cmh are bigger than the ones under the QB. Was wondering if UV had anything to do with it.

Im not too experienced with scrog. Only ran it once before on a different strain.

Same area? What temps are you running at? How much bigger are give cmh buds?

Same room. Temps about 72F lights on 66F off. 4 qb304 at 1050ma.

The CMH are a couple weeks behind at 28days vs 42, but the buds are bigger than the QBs at that period in time. Only by about 10-20% id say. I just got 1 plant under the 315w its about 30"×30" canopy. The qb setup,is over a 4 plant 54"x54" scrog.

Not complaining. Im very happy with my QB. Im also very happy with my CMH. The CMH is 4200k bulbs. QB is 3000k.

In a couple months ill have better data as ill be running 2 315w cmh over a 4x6 scrog and 6 qb304 over a 4x6 scrog and will compare #s

That's kinda what I thought. Light's in temps way too low for the less. You need to be at 82+. The leds don't have infrared heat warming the plants surface li Ljubljanaje the cmh does. Seperate them and get the led temps up.

I always thought 72F wasnt bad. Ill try. Its nearing winter here and would hate to have to run a heater just to warm my room up.

Guess ill just buy a couple CMH setups and run those in the winter and run LEDs when its warmer out.

Kind of depressing. I do have a baseboard heater in the room, but the way my,room is setup,now the res is right next to it so I have it off now. Once i harvest ill move my rdwc around so the res is outside the room so im not battling an 80F room trying to keep my water at 66F

Man I was kind of hoping it was just due to one being scrogged and the other not.

But,im glad I brought this up. Why is hotter leaf surface better for bigger buds?

72 is even pretty low for cmh. 78 would work better for both honestly.
