Cheap MH/HPS Lighting...
I just bought some 400w MH warehouse lights for $25 off of Craigslist to turn into grow lights using the method in the linked video. Has anyone tried this before? I'll let you know how it works out when I try using them over winter. (I know that's a long time away)
Also if anyone needs information on grow lights, I found this video very helpful. (I don't know how accurate it is about 24hr lighting)
