Latewood's 'little guide' to Lighting...No theory, just info!

[latewood]

thanks for the info lakewood. one question my grow room is 4x6 , can I use a 1000 watt hps. thats 840 sq ft

.thus getting the benefits of extra light coverage, all around...(I tend to want "bunch" mine close and rotate them 2-3 times daily for good light coverage with only one light) I have 6' light rail now and it allows me more plants and better overall yield per plant.
my flower room is 4x7 and I use 1000w hortilux...
