starting first grow, enough light??

my two lights just came

a fluorecsent 6 lamp t5ho fixture
(http://www.htgsupply.com/Product-GrowBright-2-Foot-6-Lamp-High-Output-T5-With-Choice-of-Bulbs.asp)

and a 150 watt hps light

do you think this is enough light for a 3' x 3' space - 4 plants

if so, what kind of outcome should i expect from this basic set up?
trying to gain as much knowlege as i can before i start sprouting my seeds,

thanks!

Yes, that will be enough for a small yeild as long as you control temps....I start all mine under T5....then move to hps about 3-4 weeks in.....

thanks,

seeds are germinating, ill update

My question is why buy that t-5 and a small hps when the 400watt hps from htg is $119, and the 400w MH/HPS conversion lamp is $169 it has to be cheaper to just pic one of those.

do you think a 400 watt hps throughout the whole veg/flowering will produce better product than the t-5 and small hps together?
