figuring a 400 is ideal for 8 square feet, I suggest you will need a 250-watt to adequately penetrate your space ... (50-watt per sq.ft. rule of thumb) ... :smokin:

As long as you can keep the temps down .
This might mean a cooltube or aircooled hood and blower but It might be worth it w/ your yields .
