Anyone know the ballpark range I can expect to get using 3 CFLs 15 watt 900 lumens each = 2,700 lumens (they are daylight 6500 K) and a 70 watt hps 6,300 lumens 2700 K) 2 Plants in a rubbermaid growbox 2 20 gallon rubbermaids put together with the lights arranged inside around the top above the canopy of the plants but only about 4 to 6 inches above the canopy for the HPS and as close as I can get the CFLs to the plants without the leaves touching the bulb.
