Hey guys, let's get back on track to help this guy out. 150 wioth CFL's is ok, but more light is recommended. 400W would be great, and more than sufficient. 2 150's, if possible would be great to as the coverage would be more evenly distributed.
It is recommended that for flowering 3000 L per square foot be used, ideally 5000. so we are working with 9 square feet, so minimally during flowering, you will have a need for 27000 lumens, to a recommended 45000 limens. 150 W HPS puts out around 15000 lumens, not really close to it. A 400 W will put out a beautiful 50000, perfect! 2 150's you are at about 30000+ a tiny bit.
I highly recommend getting either a 400, or anothjer 150 with a few small cfl's spread around!
