OTT-LITE good for marijuana plants?

Got this light today at home depot and it says its good for growing plants indoors, only 17 watts tho. are these any good? anybody ever used one of these before?

OTT-LITE

not a good idea. invest in a metal halide light you will get much better results!

works good for vegging your plant. I use it along with some cfl lights from sprout to 4 weeks old (veg time) then switch to 400 watt hps for flower time. Never had any problems with results from the ott-lite.

ok nice im planning on putting these outside once they get a little bigger. these lights dont get hot either so you can put them real close
