Smoke68 said:No problem BenSittin! 50 is ok. MJ will thrive at 35 wpsf with many people cloning on a 1foot area with only a single 13w CFL. 40-60wpsf is optimal, pushing 80-100wpsf requires CO2 injection. BTW since you have T5's you can sit that last 210 watts about 2 (maybe 3 to account for growth) inches from the growing tips
