For my county fair project this year, I want to try a different concept - something akin to square inch gardening. A couple of years ago, I ran across one of those deals too good to pass up - a couple hundred nursery pots (5" wide at the top, 6" deep) and the nursery trays to hold them. Eight pots to a tray that is the same size as a 1020.
My idea is to grow pole beans, cucumbers, lettuce (Romaine), Acorn Squash, Basil and anything else that may work in the flats - eight of each plant. I've had good success with the soil mix I make (silty dirt, compost, aged horse manure) and have the nuits I need to make sure each plant is well fed.
The trays will fit snugly into a heavy duty recycling bin that has handles. I'll be able to construct a trellis using PVC pipe and securing it to the sides with U-bolts, and using either string or bean netting for the the plants that need it to climb or be tied to. I would have fifty-six plants that take up 1400 square inches.
I would like to grow more plants but am limited by the size of the container, the plants needing to be close to ready to harvest in 90 days, plus they need to be able to withstand the summer heat. Any suggestions?
