Twin arc metal halides ??????
Has anyone used these bulbs on their system
http://www.ebay.com/itm/250W-14K-20K...ht_1977wt_1396 I think that being able to change light spectrum would be amazingly beneficial for growth and color.

I order one of the 400watt 14/20k bulbs the other day. Im thinking of interrupting the cycle mid burn so I can get 14k and 20k in the same day. Hope to get good results will let u know in a month or so.
