someone asked a question about breeding fish as a source of income, but what about plants? I know that you can sell the clippings off your plants and whatnot, but I was thinking more along the lines of having a plants-only tank, purely to grow them to sell. I've been browing aquabid and some other auctions, and it's almost horrifying how much some people charge for things like java moss, which I inadverdently brought home from the lfs with my cories and soon had at least a couple pints of. if it was a small tank, maybe the cost wouldn't be so high to set up lighting, and I think plant tanks are just as pretty...any thoughts?
