I chose to fill pots with Hydroton instead of just dumping the Hydroton into the grow bed and planting directly in that. Because this system is indoors, I want to be able to easily pull the plants out so I can wipe down the grow bed if it starts to get slimy (and smelly).
You can see that I've been dealing with slugs. One of the great perks of growing indoors will be the absence of those pests. We have free-range hens so I can't put out poison. Instead, I just go out at dusk and hunt for them. The extra bok choi plants are sharing other containers that also contain garlic, Walla Walla onions, and arugula.
We had originally built it at our farm in Sandy, Oregon. When we moved to Kitsap County four years ago, we disassembled the hoop house and tossed it into the moving truck.
It has fared very nicely. We do pressure wash it each year to remove the build-up of green gunk that coats most garden sheds in the Pacific Northwest. Next year, I expect I'll have to replace the plastic as it's becoming brittle.
There are a lot of baby plants coming up from seed in the pots right now. I've also got some plants that stick around year to year: blueberries, strawberries, sage, lavender, chives, and strawberries.
