[quote=papapayne]that also is common sense to think about. Leaves are solar panels basically...the more light they get the more energy the get thus the more energy they have to function. QUOTE]

That's the part I don't get....if the Leaf gets more light, it gets more energy. If it get's more energy, there should be less drain. If their is less drain, the Leaf should stay green longer.
(in my mind anyway). So if I have 372 watts of T5, and 150 watts of HPS, the HPS by reason should Yellow first.
Damn my questioning mind.......are they done yet? :jointsmile:
