Here are some shots of the second stage of my very first DIY grow. I vegged in a PVC/Panda Film set up under 16 large mixed spectrum CFL bulbs. Am now flowering under a 1000w air cooled HPS in a 4x4x7 air conditioned, climate controlled plywood chamber lined with RMax. Two 6" Vortex fans (1 intake, 1 outtake). 4" carbon filter for the stank. Pulling cool air into bottom of chamber from a window unit ac, venting hot clean air out window. Temps stay as cool or warm as I like. Setting window unit to 72 gives me a temp of approximately 70 degrees directly under light/near canopy. I augment humidity when necessary with a cheap cool mist humidifier. Strains: Quantum Kush, Dr.Who and Critical Sensi Star.
Question for OP, does that box count as a locked facility? Im in Michigan and was thinking of making somthing similar...Anyways let me know if you have a some time.
