Lumens question

Any idea on how many lumens I would need for a 3'L x 2'D x 5'H for 2 plants that are going to be lst and scroged in 14" 5 gallon dwc buckets?

*14" H by 12" around

aim for minimum 5000 lumens p,sq,ft u got 6 sq,ft 30000

thanks man.. how much heat do you think that would produce using cfls?

couldn't say for sure dude im hps i would say would be similar to hps should be fine as long as u have good airvlow in nd out

you think i could get away with a 250w hps with just a exhaust and intake? and if i use 250 what cfm u think i need?
