Hello daytonajim00,
You could use the container in a couple of ways. The first as two 46 gallon reservoirs. Or as the growing chamber for some plants and have the reservoir separate. It looks big and bulky, as well as heavy, so either way you may some things to consider. For the best use I think I would probably use it as the reservoir/s. You still need to make sure you can drain and clean it out easily, and that it's good and close to the ground. But You could use the large reservoir for things like rows of buckets used as a
drip system with large plants like tomato's, peppers, melons etc.. You could use the small one for another smaller system with herbs etc..
P.S.
But if it's not waterproof, you'll likely have nothing but problems. Wood and water don't play nice together.
