Peg - it IS sand - literally pure sand at least 9 feet down that we know of. Like living on the beach really, but all we add is: composted manure, soil sulphur and some Osmocote (hate using the chemicals but til we get enough natural compost I had no choice). Stuff grows like crazy, with lots of water of course!
I use the cattle panel for trellis's and have made an arbor and a cold frame from them, too. Is your hoop house sized so that you didn't have to cut the panels?
I use the plastic cups like you. It took a while to learn that seedling root systems grow very quickly and do better in the garden if they are not root bound. The plastic cups allow for transplanting seedlings from trays or peat pots to a larger container before the garden is ready.
