An automatic watering system for the greenhouse doesn't need to cost a fortune. In fact, they are very simple to make, and once set up, will allow you to get on with other things, or even go https://www.youtube.com/watch?v=Ox7DicTda0I on vacation, knowing that your plants will not shrivel up and die through lack of water while you are away.
Greenhouse plants, as we all know, need regular and frequent waterings especially during the hotter days of spring and summer.
When http://www.diynetwork.com/how-to/outdoors/landscaping/the-essential-steps-to-landscape-design-pictures you think of irrigation systems, especially automated ones, you think of lengths of tubing and expensive timers, all connected to the water supply that you may or may not have in your greenhouse.
With the system outlined in the video above, you can carry the water into the greenhouse from elsewhere, as once it is in the container you choose to use as a reservoir, it will only need the occasional topping up.
The bigger the reservoir, the less often you will need to replenish the water.
On top of the bench place a double layer of black polythene, making sure it reaches all the sides. This is to stop water from draining away naturally.
Place the capillary matting on top of this.
Attach the hose to the pump, and place in reservoir.
Fill the reservoir with water until it is around three quarters full.
Plug the pump into your timer switch, and set it to https://www.youtube.com/watch?v=Ox7DicTda0I come on for a minute or two, twice day, or more often if you live in an area of extreme heat.
Each time the pump runs, water from the reservoir will wash over all the capillary matting area, then return to the water container it came from, minus, of course, what your plants have drank and a little bit more that is absorbed by the matting.
It takes typically less than a minute to thoroughly wet the whole area, in what could be called a flood wash watering.
You can even add liquid fertilizer to the water, to make sure your plants have all the nutrients they need.
This automatic irrigation system is simple to set up, inexpensive to prepare and run, and absolutely anybody could put it together, no matter how untechnically minded you are.
Go ahead and fit one up - your plants will love you for it!
