ok os its very easy for VEG stage you need at least 3000 lumes per SqF
for flowering you need 5000 to 6000 (6 its the best or more )
you got 3 SqF so thats 9000 lumes for vegin and 18000 for flowering
if I would you i just go to homedepo get to 100watt Fluorex flood lights and you good on is little over 10000 lumes use one for veg and add one for flower
