My friend bought one of those kits on ebay. He said the veg state went wonderfully but flowering was slow and he ended up with very low yield.

Nice for these little guys.. orchids don't need nearly the amount of light that cannabis does. Look how happy they are!!!
(not my orchids btw; these were at the Mass Hort Society flower show in Boston last month)

10 watts wont work as well as 150 watt hps. You might need 30+ watts to get something useful.
