150w issn't sufficient for your current 100 gal tank for green water usage, you might want to consider a 300w MH lamp. at least a 250w

thanks CyberET! i was even thinking of the 400w. i just checked again and nobody makes the 250w and 400w mh hqi double ended bulbs in anything less than a 10,000k temp. so would i be ok in using a 10,000k bulb?

how about using 2 150w instead? i wouldn't recommend 10,000k though.. maybe matrix who uses MH can advise better.. i've been using only all natural products so far
