Absolutely amazing. I found a small block, 3.23 lbs at Safeway, a chain of grocery stores in the western United States, at $1.19 per lb. Called the local ice specialists in Prescott, AZ (2 of them), and they both refered me to the grocery store. Picked up a very small foam cooler from the store at the same time, and am expecting the poor insulation value of the thin foam to provide a moderate boil-off rate. Will know how well this works when I see how long the block lasts. Have just ordered a replacement fan motor for the burnt out fan that will be blowing directly into the area where the cooler sits, just to make sure the gas gets into the air and doesn't accumulate on the greenhouse floor.
