Thanks a lot for the reply. Don't know if you have looked into custom tanks to bring the cost down potentially but I have a roto molding facility up here that I found that does custom work and prototyping. They do insulated tanks, etc. Pretty awesome, PM me and I'll send you a link :)[/quo
I have my place but thanks. My tanks have a lot of plastic in them. Between the thickness of the tank and what I add to the insides,there is a lot of petroleum in there. The 265 gal tanks I use for my vegging must weigh 80 lbs. JK
