i got a 3 foot long by 3 foot high and 9 inches deep cab to grow in. Ive got four 27 watt day light CFL's which have 1400 lumens each. and 2 30 watt bright white bulbs. once they go to flower ill replace the four day light with 4 soft whites for flowering. I plan to have 4 plants maximum in the cab. Enough lighting or should i rig up more?
