Most definitely recommend starting out with an introduction. ;-) Much growers love everyone.Best advice to begin with would be to create a thread in "New Growers" or "Hydro" sub-forums so your question
will get some traffic rather than posting up here in this sticky...this is more of a read-only thread for info.
Welcome, BTW! Oh...that reminds me. Everybody gets more traffic for their questions if they head over to "Introductions"
and say high to everyone as well (Create an introduction thread)
Cheers!
