Also, I plan on building a raised platform that is level as my best spot for sun is on a hillside. Will be quite the chore to bring soil up there! Lol my concern is drainage...I fear water will evaporate quickly if I use fabric liner as it will get plenty of air and the fact that it is raised off the ground. Now that I saw the thread on the 400 gallon grow. I am thinking of pretty much doing what Ganga girl did but line it with felt not screening. Any thoughts...
If you do make your own and you're in a financial pinch, you can construct decent size "containers" by recycling pallets, and building a corral out of them and lining them with noncolored cardboard.
Some people have sourced old cardboard gaylords and used those as the liner. Rope, wire or nails can hold it all together. Your plants don't care what the container looks like, they do care what their roots are in though..
They end up being about 4' x 4' x 4' . If that's too voluminous, simply cut them down to the size you want. They don't move very well, but neither do fabric pots over 100 gallons.
Pallets if you're industrious can be sourced free or cheaply. They also make good firewood or compost eventually when they're done as grow pots. Get two birds stoned at once, etc. Good luck.
