So there is a closet leading into a crawlspace underneith my basement stairs. There's just a 2' x 4' hole in the back closet wall that leads underneath the stairs. The closet currently has one of those cheap old sliding-curtain doors.... I Put a plywood door w/ a deadbolt at the back of the closet where the crawlspace starts...

The flourescent fixture is on an angle that runs parallel to the stairs, and in line under them are shelves w/ growing trays to house 6 seedlings each. An opaque vinyl curtain separates that half of the crawl with the other half (for flowering).

Each side of the curtain has one air purifier/ionizer, and there is one small fan for circulation.

Doing 4 strains: Mandala White Satin, White Widow, Northern Lights, and some Diesel from my last bag.
