I just noticed that the wholesale company I Christmas shop from has bags for ten cents: http://www.dpciwholesale.com/Reusabl...#product_tabs1

I read the link about lead. There are two green ones like the Barnes and Noble bag. One tested 298 ppm and the other 235 ppm.

I was reading about lead here:
http://www.extension.umn.edu/garden/...n-home-garden/

In general, plants do not absorb or accumulate lead. However, in soils testing high in lead, it is possible for some lead to be taken up. Studies have shown that lead does not readily accumulate in the fruiting parts of vegetable and fruit crops (e.g., corn, beans, squash, tomatoes, strawberries, apples). Higher concentrations are more likely to be found in leafy vegetables (e.g., lettuce) and on the surface of root crops (e.g., carrots).
Since plants do not take up large quantities of soil lead, the lead levels in soil considered safe for plants will be much higher than soil lead levels where eating of soil is a concern (pica). Generally, it has been considered safe to use garden produce grown in soils with total lead levels less than 300 ppm. The risk of lead poisoning through the food chain increases as the soil lead level rises above this concentration. Even at soil levels above 300 ppm, most of the risk is from lead contaminated soil or dust deposits on the plants rather than from uptake of lead by the plant.

The bag dimensions are 12" x 8" x 13" which is 1,248 cubic inches....5.4 Gallons.

5-gallon air pots are about $3 each on Amazon. Getting the equivalent of one for ten cents looks like a really good deal.


By the way, DPCI has a $100 minimum order, but they sell a lot of other stuff.
