50 watts a square foot minimum, so thats 16 square feet, or 4 foot by 4 foot.

you have 70 sq ft . 1 plant/2 sq ft = 35 plants

Id go under the max amount for footage to make sure you get even light coverage.If you go side by side with a small overlap Id say you can do a good 24 under the 2 lights with good air flow room and controlability.I do 32 under 3 400 watt lights or 32 under 2 600 watt lights and find thats about max as the outter edge plants dont get as much light and suffer from it.

kinda lost on this site how do create a post i have many questions thanks

14 ft by 5 ft.. you could use 2 6 foot light movers and cover more plants.
