Smart Pots Dollar Store Bags?

I'm looking at doing some in smart pots. I thought about these reuseable bags seem a lot like those and I googled it...seems like other people thought of the same. Almost all the stores around here have those type of bags that are mesh like the smart pots they sell at the grow store. I found some that are green and one store even has black ones.....Any thoughts on trying these? Im thinking trans plant into for flowering I dont know about reuseing like the smart pots...plus there only 25 cents

yup......fill it with water. if it runs through, you're good.

a lot of people use them and from the results they sound like they work the exact same way. they let oxygen in through the walls allowing the roots to easily get oxygen and they stop roots from getting root bound
