another dispatch from our guerilla gardener
I mentioned last week that I would go over seeding trays. I may have to make a video some time to explain the equipment. The basic gist is you have a tray of styrofoam squares about 1cmx1cm each packed with a loose potting soil. These trays have tiny holes in the bottom for draining. There is a metal piece that fits perfectly over the styrofoam trays with a tiny hole for each individual square. The metal piece is attached to a hard plastic fitting that is vacuum sealable, apart from the tiny holes. You use a vacuum cleaner to create the suction in these tiny holes where you get at least one seed to stick in every hole, pending on the size of the seeds. You place the metal piece onto the styrofoam tray and release the suction. This drops a seed in each individual 1cmx1cm square. Then you place the tray into the water bath in the greenhouse where water is allowed to soak in the bottom.
