Recycle and Reuse
I agree the cardboard box is not user friendly. They go away from the plastic for "environmental reasons". I, however, liked to reuse the plastic pails in my garden. I would drill holes along the bottom and bury the pails between my tomato plants. Then I could fill the pails with water, fertalizer, etc and it would slowly feed the plants as the day went along.
No more wet plants, no more wilting in the middle of the day, and I was able to re-use. The pails would last about two seasons in the sun before they would crack and have to be replaced.
