Yes I have a fan directly on the light... here I'll find a pic of the whole setup... I have the plants about 3 feet away from the light. (I just tested my pH.) Wow... it was incredibly high around 8 if not higher... I added pH Down and got it around 6-6.5. I don't know my ppm, what do I need to find that out. I'll take more pics in the morning... but I also noticed that the tips are browning... what's that mean? {{Pic is not up to date setup, but shows how the light and fan are setup}} Thanks for all the help!
