dont worry about leccy mate
a 600w hps in a perfect enviroment should return 300-600g off top quality sensi buds every 12-14 weeks
10-20oz @ £100-£160 per oz
= no problem finding 50p for the meter

crack on mate

BuddyLove Reviewed by BuddyLove on . Unsure about 400 VS 600 HPS I plan on having a 16 plant sea of green in a 4X4 (one plant per square foot), using some kind of hydro (flood and drain) in some kind of medium. Now my question is, even though all the books say 400 watt HPS is OK for a 4X4, will it be enough for 16 plants? Would it be OK to suppliment it with some CFLS or do you think it's neccessary I get a 600w? Rating: 5
