A 150 HPS with in a 4x4x4 space just does not quite cut it using the SCROG technique. How large could I go? I was thinking at least 250 HPS. Do you think 400 HPS would run to HOT?

Thank You
 
is a cool tube an option money wise? if so go 400w for sure, a 400 in a small space like that if vented should produce some good shit
