Wow, 4 or five bucks. Here the cheapest you can get them is $8 and they're usually more like $12. I guess it reflects our very long drought and the relatively higher price of fuel.
Great idea though. I used one to grow some lettuces and cucumbers last year and it worked very well. I watered it a couple of times with some seaweed extract and fish emulsion in the beginning just to give it a kick start but didn't do anything more after that.
