Enough lumens for 56 sq ft?

[xcrispi]

Are you talking cubic feet , or square feet ?

length x width = square feet .
length x width x height = cubic feet .

56 square feet of floorspace = 56 ft x 50 w. per square foot = 2800 watts .

How big is your space length and width ?

A guy I know is selling a 150W & 400W HPS light. The 150W comes with a bulb for $75, the 400W has no bulb for $150. Here's my question..should I buy the 150 or 400W light? Would a 150W HPS & 250W MH throw off enough lumens for 3-4 plants in my 56 sq ft closet? Thanks to all who answer! Rating: 5
