minimum 3k per sq foot???...thats good lighting not min. a 10k lumen light is week. even a 400 mh has about 30k. how does a cfl grow them if we need min 3k. thsoe dont come anywhere enar that but yet they grow. so like i said, that isnt a min number, thats the average to good lumen level we use. what light you sue that can get a foot print of 10k per sq foot
