Agreed. If I had a grow ROOM instead of a grow CLOSET, I'd defo go w/a 400W HPS. But instead I have ~250W of CFT flouro for about 18000L covering about 2 ft². Total cost for my closet to date has been $5 for mylar gift wrap & $7 on my first CFT way back when. (new bulbs are "donations" [I have a stoner buddy at Home Depot that I try not to abuse], fixtures are salvage) But at cost, bulbs woulda been ~$90.- + tax. It's $12.95 for either a single 42W 2700K or a 2-pack of 27W 6500K. About the same as a 90W HPS security light. (at Home Depot)
