I'm suplementing a light with a pair of similar cobs. Made a big difference! I've got some of the nicest looking seed plants I've grown yet! They usually look like they'd say: GET these things outta me..............lol! I'll get a pic
I'm thinking about getting 2 COB's to use combined with a ViparSpectra 1000, in a 4 x 4 tent. I may just get them from the site here if I don't feel comfortable building it myself.
