Wait what?? T5 bulbs in what ?? not that HID..
i did not know u were using a T5 y did u say so, i my self am using a t5
but in ur picture that a hps so what are u using the t5 for?
VV i was talking to someone i know the other day and he told me that the T'5 only has good light penetration about 6 to 10 inch's from the light is this true?
if so i got alot of triming to do!
gotta open up those bud sites.
Rain water?? hmmm i dont know about that to tell u the truth, but it maybe better but it might be worse too. alot of polution goes into the air and create acid rain but don't quote me on that.
When i top my plants i top the very new growth so there is nothing realy to make a clone of.
But if u cut lower i guess it could work its a growth tip.
