Plants are looking good bro. I wish i could see how ur RF 66 is setup on the inside. Im sure it has misters.
hotness...im guessing your basement does not get very hot. Those roots look very healthy and alive.
I have a rainforest and use it for cloning/mothers sometimes. Screen is a perfect application for these things. Show us some buds pictures already.
Did you use blue light at all or just the hps?
also I think you could stand to put your light a bit closer to your plants. Especially since you took the time to cool the light so well.
also your initial round of pictures had your plants looking very healthy enjoying their environment.
Now you have a lot of leaf drooping going on in the 2nd round of pictures. How about an updates?
I'm just srarting a big Bud . NL grow and am really pumped up . they are looking good and haven'd strtched much so far.
