did you see the bottom of page 2? i will eventually rebuild but this system is going to be what i use . I will possibly put something hardier in there such as an aerocloned mint,basil, or parsley plant. Once i fill that one ill build another and make a common reservoir , and from there ill have the whole box filled up, and it should be summer! all's it is is a 2x4 framed box that sits in the window and is 4 feet high (length of window/windowfarm) it's insulated to keep heat in and ill eventually design it so i put the res next to the cold window and use a heater or something.
