Originally the cfl's i bought were not strong enough to help the plants, since i was the one to buy all the bulbs last, my partner in crime had to buy the next ones, we went and purchased flourescent lighting. we got two GE residential light 48" F40T12 light output: 3150 lumens energy used: 40watts color temp: 4100K Cri: 72 I was wondering if this would be the suitable enough through flowering? or should i get a bulb with a lumens of over 2000 but a higher color temp?
