Fabric containers air prune the roots and make it very hard to overwater a CBD plant, which is why so many growers switched to them. The trade off is that they dry out fast in a hot tent or on a sunny patio, sometimes needing water daily by midsummer.

For anyone who travels or forgets to water, plastic remains more forgiving.
