hey, i know there are some low tech ops, but when i start as a newbie i want a decent system, so i'm outdoors to rake in a few bucks to go indoor with the op. I'm thinking greenhouse though.. maybe something like a downhill water system with nutrients in the water and coconut poit in the pots...... i've seen one like that with tomatoes. very simple ,very clean, very sustainable, very cool, and uses the SUN. neat. another cool idea i heard and drew up plans for is having a cheapo above ground pool installed and then building a small deck and pump housing shed around it (heated small pools are totally in) and using the pool as the resevoir and cooling system, the deck takes exhaust into it and vents through the boards, along with housing your co2 tanks. you'd have perfect pest control, as any vents would have a carbon lining (you can buy cheapies for the intake, since there's no smell there) and it's be expected to be loud, as it's a pump shed. and you can even swim a limited amount in the pool, as the nutrients would be added within the hydro tubes, but i haven't worked out all the kinks. just heard about it and ran away with it , but still neat, i think!
