How many lumens......?

I have a 2'x4'x5' Grow Hut, 40cuft. How many lumens would I need to be optimal for flower? I have currently a 90w TriBand UFO, a 2tube Shoplight w/Nat.Sunshine Bulbs and a 68w CFL(2700k;10,000 Lumens). Curious to have this 1 answered. Thanks in advance :thumbsup: :thumbsup:

3,000 lumens per square foot is minimum with adequate growth, 5,000 is better.
I'll let you do the math

the problem with this question is that LEDs lumens don't add up like fluros or HID etc.

i've seen some impressive plants just under the 90W UFOs. you might want to supplement with that CFL and use the tube light to start clones or something?
