questions on ebb and flow setup

This the setup im planining using.each table is 28x20x6 and 11 6 in pots fits in each side, my main question what size light do yall think will be adequate to,i was thinking a 400w hps because i will have it in my closet in apt.(ive been growing for 3 years here)also first time to do ebb and flow setup, i would be starting 11 plants and then waiting two weeks than starting other tray.planning taking off this batch

get a six hundred watt probly do more 4 you in the long run (but thts just me)

I would also say a 600 but if you're growing in a closet I would go with T-5's or something that produces less heat. Just my .02

im sticking with hps, a 600w will be to much to add on electricty bill

...actually, a 600HPS w/ digital ballest only cost me about 30 bucks a month to run. What kind of fertz ya using with your ebb'n flow? I switched a few months back from soil to hydro (ebb'n flow) ...and I'll never grow in soil again. I'm using the Lucas formula.

im using dyno grow nutes,im more worried bout heat than what it adds on to my bill, im willing to get 600 if the heat sig is not that much bigger

I am using a 600W light and my electric bill went up $20 a month. Also, I am doing a Ebb and Flow on a 2x4 table and in a 4x4 closet. My table is very crowded with 6 plants in it. Buds look excelent but it is crowded. Using 6x6 Rockwool blocks from start to finish.
