hey all, ive got a 90 X 60 X 60 growbox and am going to use cfls for my first grow and i was wondering how many watts i will need to do the whole proccess including flowering if possible and how many lumens? thanks heaps
Depends on how many plants you will grow. You can grow with 35 watts per square foot and be just fine but, 50 watts per square foot is even better. The more light you can get the better.
