Considering on making DWC Bubblers and selling on Internet for supplemental income

dbkick.. nice looking system in your pics. Very clean. I'm a DWC guy myself, but I think your setup has potential. As far as selling it, I don't think you would have much success in any market but mj growing. If your resivoir was someting other than a cooler, I think it would be able to sell to a wider audience.

And remember, when dealing with trolls... they hate fire.
