what's "PH"?
I once read a book where an author called himself severely funny...I think the 2 of u may have something in common.
very fun grow style too, i am definitely excited to try something tiered like this, and let the plants get all da light, with no need for reflecting walls, though with 1 400 MH and 1 400 HPS (both are in reflectors, though) i'm not sure how big i can go, probably like 15 plants - 2 rows of 3 bottom and 2 rows of four 1 on top/both sides of the bottom rows- does that sound reasonable, with tall 2 gallon small tree pots? Nomination for run-on of the year? LOL
Thanks for the free education +REP
