Getting too crowded

[GigaGrew]

90f tops in my humble opinion with a RH of maybe 30-40%

FYI MH makes more heat =(

yeah u can get away with slightly higher temps with co2 but 90f is still pushing it. trust me, if its an option switch to 2 hps or go back to 1 bulb. i all for more light but not if environment cant handle it.

I'd just go with the HPS ..... that's what I use to veg and they still grow like crazy.
