Although cannabis is my primary interest, I also work part time with local organic farms.
I have used a lot of different containers and seen thousands of the same type of plant grow side-by-side.... and for large-scale production where a controlled media environment is desired, and a container of volume of over 25 gallons is required.... it's either burlap, or wooden-crates. But if you're going to use burlap and the plant is going to be cultivated indoors you might as well throw it on a plastic pallet base…
If you're having any trouble with the burlap container holding too much or too little water, all you have do is add or subtract layers to achieve the desired moisture level.
It cost pennies, and is very easy to install and manipulate.
It is what commercial farmers use when working with thousands of plants,fluctuating market values,shitty margins and high labor cost....Plus it's completely natural and you're not contributing to The gigantic carbon footprint of The plastics industry.
