HPS?

[whitestalkslongwalks]

i dont understand how can people flower with cfl....it would take 6, 1k lumas (spelling?) to equal one hps.....n i see people flower 4-5 plant with though.....soo shouldnt i be able to flower 4-5 with a 70wat hps?

that's really anemic. i was only going to flower two under a 250w hps, maybe three

250w hps gives 29000 lumens
