Okay I am getting ready to build my Coolidor. I am going out to Wal-Mart to buy the cooler, I hope to only pay about 30 - 40 dollars. The cedar I can get for 5 dollars for a foot of 1/2 inch thick. as for the damn Propelyne Glycol, well that is a bit elusive to get, still looking. Next comes the florist sponge, got that for about 6 dollars. I also picked up an additional hygrometer for free from a friend. I think the last thing I need, I stole from the kitchen was a tupper container. I hope to get this all put together by this Saturday. I will post a PIC of the finished product soon. If anybody else has built one(coolidor) any advice on avoiding mistakes or just some advice on how to put it together let me know.
