I use a 250w cfl to start off my girls atm, nothing stopping you using a smaller wattage if your only starting a few beans at a time. In my old cab i use 4ft tubes x 4, lower wattage but better coverage i can sit plenty of young seedlings under them.Thanks for that. I'll look into that as well. How many watts are you using on cfl's? (effective watts that is).
