If you want a small self watering tray this tray which is made of a “Collect” IKEA box an option that you can build yourself. What you need is a plastic box “Collect” dimensions 39 x 28 x 14 cm and a piece of plastic sheet and a piece of kapillärmatta.
Here's how to:
Put the box up and down on the plastic disc and draw of. Then cut or cut out about 1 cm inside line.
Delete a bit extra ca 1 cm on one long side where kapillärmattan to be knit into the box.
Delete a bit in one of the corners to get a hole to where you can refill water.
Fit the plastic piece in the box, It should rest on the two lugs that are on the short sides and on one long side of the box. Make sure that there will be a gap at one long side where kapillärmattan sticks down.
Clips to kapillärmattan (I took two pieces when I had a spill) Wet carpet and put it in place, Dip the ends of the box and make up.
Set on genomvattnade small pots with holes or a salad with holes in the bottom.
I have used a translucent box then I had one at förådet but it is probably better off with a black then will not light for water and then there will be no any algae formation in water box.
Yes harder than it was to get your own little self watering tray
