I have just purchased some lights and would like to know about how many nice plants i could grow under them. In total i now have :
VEG
2 x 16w fluro tubes 900lumens 6400k
2 x 17w fluro tubes 860lumens 6400k
2 x 23w compact fluros 1450lumens 6400k
1 x 23w compact fluro 1550lumens 2600k
FLOWER
Same as above but using only 2400 and 2600k warm white bulbs which have a slightly higher lumen rating than the daylight bulbs, so there will be a few bonus lumens thrown in.

Peace
