Wally Bags are back!
After several weeks being out-of-stock, the local Wally has them for sale. I bought 2 to compare to the other two essentially identical bags purchased at the library. (50 cents more, but you can feel good about where the $ is going.) The things are huge (perhaps a hair too big?), sturdy enough, and - best of all - they breathe, offering the plants some much needed evaporative cooling. This will be critical to by table-top garden growing here in southern Arizona. We're entering a bit of a cool spell (only low 90s today!), but I plan to take soil temperature measurements next week when it gets back near 100. I suspect the bags will drop soil temps significantly, at the cost of more frequent watering and possible (?) salt build up.
