Drainage when using cloth bags.

[Sun Ra]

Just wondering if other growers also put scoria or clay balls, etc at the bottom of cloth bags - ie. under the soil, to assist with run off.
I also sit the bags on a plastic grill type thing to allow air underneath and run off and so they don't sit in run off. Am I doing this right ? Talking indoor, but I'd do the same outdoor if using cloth pots and not growing in the ground.

@itchybro had an interesting insight into that subject HERE
