grow lights?

Ok, I've always been an outdoor grower, but am trying my hand at growing hydro and in soil indoors. here's what I've got going.... 6'w X 8'L X 6.5' H fully covered with mylar included ceiling. exhaust fan and fan for cooling. my shed is fully insulated for the hard upcoming winter and heated. currently I have 4 nice ppp about 12'' tall in continuous drip system and very bushy, and 4 great white shark in soil. I am using (3) stealth hydro system's 45watts (veg) at 2300 lumens per light. now I know this isn't enough light to get them to grow a little faster, so I need some output and where I can get better light system preferable high intensity so one light will cover all. any help will greatly appreciated. plants are about 1 month old now. they look good, but just seem to grow a little slow, I think. I may be a just neverous nellie. thanks!!!

I would try craigslist, you can find lights pretty cheep, also talk them down a bit. Hope it helps.

Be careful buying off craigslist as the light may look bright, but it won't output the requried lumens because it's too used up.

Got any local hydroponic stores?

Try High Tech Garden Supply they kick ass

Even if the bulbs are at the end of usefull light, If you buy the light cheep enough a replacement bulb is prob. worth it. I got a 58x58x78.5 tent, 400w hps, with mh conversion bulb and a shit ton of stuff from some guy for 275usd. It was well over a grand new. Htg light, and tent has built in vent for light heat to be extracted with small fan, keeps tent temp down. But this is my .02
