You would be using potting soil - these pots have no dirt as they get their nutrients from fertilizer in the water. The medium in the pots is packed coconut fiber that holds the water/nutrients and holds the plants in place. There are special instructions for locating tomatoes. There is a pdr file about putting this thing together with instructions how to place the plants based on what they are.

The two ground pots are larger pots for larger veggies.

I'll look around that site more.

I use a what is called a soiless mix for my indoor plants. It’s just peat moss, compost and vermiculite, about equal proportions. Then each year just refurbish with my own compost from kitchen scraps and leaves and shredded papers.

It works for where we are and what we have to deal with. Hydroponics though may be good for you. The dvd I was thinking of is called Food Inc. I think. I watched it on netflix.

The brief part on hydroponics and the fish tank which provides nutrients for the plants etc was interesting to see.

Let me know what you find out. I have to go pressure cook some chicken for storage.
