Hi everyone I am currently doing a 14 auto plant grow useing a 600w cool tube in a grow tent that is 5' 8" by 5'8" and I have done a lot of reading up but I was under the impression that a 600w mh and hps would be enough for this size tent I however am really worried that I am way under the recommended lumens per sq ft that everyone is saying online the hps is 90,000 lumens that's only around 2500 per sq ft. Is this going to not be enough to have a good yield? I am hoping for 6 to 7 zips. Thanks everyone any options would be great!
