Read up on Lumens and PAR recommendations for your size grow area and that will help you determine optimal or atleast minimal lighting needed. Optimal Lighting for MMJ is around 3000-6000 lumens per square foot and that account for about 5 feet of light loss. 2 600 watt hps will be about the minmum lighting needed for a 8x8 area with 4 600w hps being optimal.
1.2m tents fits 50 girls perfectly under 2 x 600w HPS in cool tubes, no heat issues and hope to pull 1oz per .. it can be done, SOG with 10days of veg, harvest 1st Jan
