The watering system
For the watering system I needed to obviously keep the soil moist and also not soak the floor of the shed.
I decided on a water recycling system, this way what ever passed through the soil would return to the water storage container for use again.
hopefully meaning I would be able to fill up a container only now and again.
To achieve this watering system I need to lift the trays I was going to use off the floor.
I found some cheap blocks at a local hardware store and I also had a few house bricks hanging around.
I bought some guttering an end stop and a corner piece to complete the trough to send any lost water back to the water container.
The trough was slightly higher than the blocks so I had to add a few bits of wood cutoff I had hanging around to level things up.
I drilled some holes in the trays to line up with the trough below.
This way any water then passed through the soil would drain into the trough then return to the water storage container.
As the trays are black and will absorb heat I decided to cover them in multi layer insulation.
The water itself is supplied by a 12V pump in a container in the corner of the shed, I fitted a clear hose pipe to the pump so I can see the water flow and then fitted garden sprinklers in the hose pipe.
I also fitted a non return valve which should stop the bubbles forming in the tubes and the heads from spitting.
