c02

looks good simple and effective

you might want to put your cup of water above the plant on a shelf or something since co2 is heaver than air it will fall down on top of the whole plant

yeah i might do that if i heave enuff space to build a shelf
cheers all :)

i drilled a hole alittle smaller than my tube in the lid of a jar and stuffed the tubeing thru the hole in the center down into the water then i drilled alot of little holes in the top of the lid then i hung the jar from the wall above the plants by the hose then when you need more water in the jar just unscrew it and take the jar off

this is the system that i have been useing it seems to work better than nothing maybe this will give you a few ideas
good luck

Hope your neighbor isn't schrodinger, bet he'd have something to say.
