Okay then, the girls have been in flower for 4 full days now and growth is going well. They are still running on veg nutes at the moment, but I will switch to flower nutes in the next day or so. With the addition of the cooltube I am able to keep the 400w light about an inch or two from the top of the plant which is great. And the ambient temps are running in at about mid 70's (farenheit). I LOVE COOLTUBES! :jointsmile:
