hi Bush Dr can i ask how long you would veg chemdawg for ?...
Assuming we're talking about a well rooted clone, about 3-4 weeks or until it's 15-18" tall
Marlo is spot on about using any media......his grows are very good and you should check them out......soil is probably a simpler bet for your first grow
Most of us learned our trade as rednecks working good old dirt
