I just switched to compact 42 watt "twisty" floros, at 2700 lumins each. and i pay $8 each for them. the package says they last 13000 hours. personally i think they have the most bang for the buck. i have a limited grow space, currently 2 square feet, 10 cubic feet. grow is going great, as good as the hps i was using. also, when i was using hps, i had one bulb. now that i am using floro, i have six to get the same lumins, with about 100 more watts. the advanage is he expense should one burn out. also if one burns out, i still have 83% of my light. |
