I'm real excited about growing indoors for the first time. I just bought an all-in-one setup from EBAY that includes a switchable 400 Watt HPS/MH lamp w/reflector & the bulbs for only $255. I'd highly recommend you look on ebay first before going to some of these other merchants online (highway robbery!). I got the idea to grow after wondering what the hell to do with this huge box my treadmill was delivered in. Eureka! I'll make it into a grow box. It's 35"x 21"x 48". A perfect 15 sq. ft grow area. I also purchased seeds from worldwideseeds.com (Marley's Collie, an Indica). Can anyone advise about the fan? Those things are expensive. There's a squirrel cage CFM465 now on ebay that's up to $36. I don't think I'm going to get a break on that cost (their $89 at Grainger!). Well hopefully this indoor setup will work as well as the plants I grew on my fire escape years ago
