just got 3 100W and 1 150W lights, the eco friendly kind that only use 23 w for 100 w. just wanted to see if that would be sufficient lighting for 8 plants (4 by 2) (almost 8 square feet) thanks
just to add on to that whats the difference? because i got those eco friendly 3 100w bulbs.. it says 27w=100w... are they less powerful? will 3 of them work for a small space 2-3 plant grow?
Equivalent ratings on CFL's are to be ignored. If you have 3 27W=100W bulbs... you should only count them as 81W total.
