Doug, It took maybe $10 to fix this thing, and it will hold 100 or more 1g plants, help keep them warm, and allow a high humidity environment. My big greenhouse (8' x 8") will hold a lot more, but was about $800 to build, and took a couple days. The was $69 and took maybe an hour and a half, even with the mods. If It allows me to produce 5-6 more plants, it pays for itself.
