Got a coupe 40 watt, 2800 lumens energy saver bulbs and a 2150 lumens one all daylight light, not soft white. How many lumens do you need per plant? is there a standard of somekind?
I dont know... I have just over 3k(usually around 2k) lumens for veg on 5-6 plants at a time In a 12 x 18"ish space and I've been worried my plants aren't stretching enough. After about a month they are only 2 1/2 - 3 inches high. I do keep the lights very close though and with more lumens you could cover more space.
The point is that I think you can get away with what you got, with minimum stretch. at least for veg.
