First outdoor grow yeilded an oz from a total of 4 plants. Building a 4x8 at 5' tall. Space divided with 4x6 for flowering and the remaining 4x2 for clones and a mother. Have a 6" in-line fan at 160 cfm = 1 air change per minute, ( 4x8= 32 x 5= 160 cf) intake vent ~= 0.5 sf. Insulated with recycled styrofoam on the walls then covered with "Space Blanket" aluminized mylar 4 ceiling and walls. Mother and clones will be hydroponic under 6500k CFL lighting @ sides and overhead until I transplant into good organic soil for flowering in 3 gallon "Smart Pots" and 150 watt 2700k cfl. I'll post some pics at a later date. Any suggestions would be appreciated - Thanks
