GrowinGreen23 Reviewed by GrowinGreen23 on . HOW DO YOU GUYS FEEL ABOUT... 1) Using miracle grow potting mix with continuous realease plant food? 2) Using a 2,700 lumen (42 watt) CFL-like bulb (does not label itself as CFL on package but is similar to other CFL's) for 1 sq.ft. of coverage? I have checked the FAQ's for answers to these questions. Rating: 5
