Good stuff chromophore, very useful info. PAR's are a little out of my league at this point. Lol....I do keep the T5's within 6"s of the plant tops, and I think another big factor is the LST I do when they are only about a week into flower. It works with my stumpy strain, but I suspect I would not be so lucky with a "leggier" strain.
Talk about luck...bringing those seeds back from Maui...Germinating them 2 years later....having the lone survivor of the original 8 seedlings be 5 feet tall, and then having all clones be short and stumpy.
Damn....even a blind squirrel finds a nut now and then! Thank goodness plants are resilient, even I can't seem to screw 'em up too bad.
