New Grower Hydro ...during flush questions

[gmgeoff]

Ok, I started my flush yesterday and I have three questions.

1. Do I need to continue cooling my water? ( temp. may rise to 78 +or- DF)

2. Hmmm..I forgot #2 :smoke:

3. Due to high temps..up to 90 degrees at the canopy top, I have cut my lighting in half (from 700 output watts to 300).
So i will have better temps. (10 degrees less) ,but less light, as the buds appear to be still bulking out some.
I'm thinking the cooler temps. would be more beneficial than full lighting.

Advice please

1) yes, cooler temps in hydro for sure!
2)cant help ya, except pass you this:Sharing One:

3) You will want the lumens the last few weeks of the cleanse, due to them giving a big push and nulk up real well, final yields will suffer a bit and in my opinion, it can be substantial!

Thanks briman,
but unfortunately I can't do lower temps without cutting some lighting. 720 watts of LEDs are just as hot as a 720 watt MH. And at least with that it is probably easier to remove heat with a cooling tube.

So you you think lumen s over temp. is more important at this stage?
