Building their own self watering tray is not that hard. Here I describe how I do a self watering tray of a flat washer, plastic disc and a plastic tube. You need a disk with at least 4 cm deep, a plastic sheet of any material about. 5 – 8 mm thick as well as a plastic tube and montagelim + a kapillärmatta/irrigation mat.
Place the tray with the bottom down to the plastic disc and draw of, draw a small square on the short side of the plastic disc, where should the hole be for water filling. Now it's just sawing or cutting out plastic disc after lines.
Now put the disc in the tray and check to match. On the short side, where kapillärmatta will be down, it should be a gap of about 1 – 2 cm.
Cut to 4 – 8 St. haul of plastic tube in this case is related to the pieces 4 cm long, then plastic disc should lie flush with the upper edge of the tray when you put down the plastic disc in the tray. The 4 – 8 distances of plastic tubing place reasonably evenly over the surface of the disc, plastic and glue them with montagelim.
When everything dried, just turn on the plastic disc and put it in the washer and clips to kapillärmattan to match, CA 1 DM to knit down into the slot on the short side.
Now it's just to wet carpet (is done easiest in the shower) and put it on the plastic disc and stick down one end of the tray, fill with water and place it on your pots with holes in the bottom. Keep in mind that the pots must be genomvattnade when they are put on to be able to suck up water, pressure to them some easy.
Now you have your own self watering tray.
In this example, I have a large flat washer “Grow Bag Tray” size 100 CMX 40 cm. Height 4 cm but it is of course to use other sizes just the depth is at least 4 cm.
