a little info for those who haven't seen my prior grows ... I grow indoors in a cabinet I built ... 2' x 4' x 7' ... I use a 400-watt high-pressure sodium lamp, fan-cooled hood, and a couple of additional fans for exhaust and air movement on the plants ... a 24-hour oscillating fan makes for strong stems, and less risk of mildew or molds forming ... I still don't have the temps down where I would like, I'm running around 85 degrees, but am shooting for 75 ... I may build another new cabinet soon, with much more ventilation ... I am playing with the idea of building an 'open-top' design, with the warm air blowing though a cabinet roof-mounted activated charcoal screen, much like a furnace filter ... I use a couple of odor-neutralizing ionizing bulbs http://www.1000bulbs.com/product.php?product=9135 (they work great), so odor has been insignificant, so far ... I use #5 pots, my water is purified reverse-osmosis, and my nutes are 'Earth Juice' varieties ... I have switched to Fox Farms Ocean Forest soil, but, as mentioned earlier, I found this soil was burning up my young seedlings ... I will use the soil when I transplant into my #5 pots, however ... hope some of this helps ... :smokin:
