Autowatering in the greenhouse

Autowatering systems for greenhouses can be invaluable to gardeners with busy lives, as they ensure consistent and efficient watering of plants, carefree of having to manually turn on the taps. This automated system incorporates a convenient timer and a reliable soil moisture sensor for optimal watering, all setup with nearly zero effort. Not only that, it also enables gardeners to save up to 40% of water used for irrigation due to its effective regulation. With added advantages, such as resistance to temperature-variations, autowatering systems are gaining a lot of traction as the ideal irrigation solution for greenhouses.

The garden takes away all your free time and energy, and with a long separation, you worry about the health of green spaces? It’s time to get an assistant, at least for watering the greenhouse, having arranged for yourself a real summer vacation. Hiring someone is expensive … How about investing time and money once, giving the task of irrigation to automation?

DIY automatic watering system

Automatic watering implies minimal human involvement or its complete absence during process automation. You can build such an automatic watering with your own hands. The event is painstaking and costly, but subsequently pays for itself due to saving time on manual watering and increasing productivity – the risks of farming in hot, dry weather are reduced.

Homemade irrigation system in the greenhouse

If you set a timer with a valve mechanism and take care of uninterrupted water supply to the site, then you can carry out forced irrigation in the greenhouse for a given time. It’s possible to control autowatering in a greenhouse using a GSM-controller completely remotely from any location on the globe that is part of the coverage network of mobile operators.

As sources of water for automatic irrigation, summer, central water supply, a well or a well with a pump, a barrel are used. A very simple way with zero price is to water from old plastic bottles that allow plants to stretch out in the greenhouse without your participation for up to 3-4 days. According to the type of supply of moisture to greenhouse crops, there are several types of automatic irrigation.

DIY drip irrigation in the greenhouse

With drip irrigation, moisture flows slowly and purposefully – right to the root of the plant. Thus, evaporation of water from the soil surface is reduced, weeds are deprived of water supply, and the root of a crop fed in this way grows deeper into the earth, which gives the ability to find moisture under extreme conditions. Sunburn on leaves is excluded. Plants need to be located in close proximity to moisture supply points.

Automatic drip irrigation for barrel greenhouse

Such a system of automatic irrigation in a greenhouse in the presence of a water supply can be connected directly to it through a tap, but it is preferable to do this through a drive – a tank or a barrel. You need to place them in a greenhouse or a place well warmed by the sun. The capacity should be at an elevation of a meter from ground level to create gravity flow. For automatic water intake into the barrel, you can install a mechanism widely used in plumbing – a valve with a float.

In the bottom of the barrel, you need to make a hole, install a plug, attach the central line – a hose or a finished drip tape. It is advisable to use a filter between the plug and the trunk – so autowatering in the greenhouse will last longer. A plastic pipe is also suitable, but it is inconvenient due to the low maneuverability on the bed.

You will have to tinker with a hose or pipe for autowatering. If you just make holes for irrigation in them, then the water will not drip, but pour. To avoid this, you will have to buy external droppers according to the number of plants watered. They are devices that regulate the speed of irrigation. They are cut with the help of a punch of the corresponding diameter, for operation they are stacked with the side not down to the ground, but on the side or top of the hose.

It will be quite inexpensive to pull small diameter tubes through the highway (as in medical droppers) with a small hole in the center that goes into the hose. In this case, the diameter of the punched hole in the hose should be slightly smaller than that of the dropper supplied to the plants. It is threaded through from both sides into a hose heated with hot water – with a screw screwed into the end of the tube – like a needle with a thread.

If you have no time to work with a hole punch and install droppers, then it makes sense to take a drip tape. This is a hose with ready-made holes in increments of 10-50 cm. Inside there is an element in the form of a capillary maze, passing through which, water slows down and flows out drop by drop. The service life of the tape is from 1-5 years, and for a home-made system with droppers up to 10. In addition, the automatic drip irrigation system using tape requires cleaning for storage in the winter.

Do-it-yourself automatic watering system from a plastic bottle

This method of drip irrigation for the greenhouse is suitable for saving capricious pets from drought. A 2-liter plastic bottle may last 1-2 days for automatic watering. How to make bottle watering in a greenhouse:

  1. Cut the bottom of the bottle to the end to form something like a hinged lid.
  2. Firmly fix it to the peg in an inverted form, which is stuck as close as possible to the plant, and serves as a support for the bottle.
  3. To prevent water from spreading, form a small hole under the neck in the ground.
  4. Fill the bottle with water by folding the home-made lid, slightly unscrew the stopper, adjusting the rate of droplet separation.
  5. If desired, hang such bottles on a support for gartering plants.

Rain automatic irrigation in the greenhouse

With this method of autowatering, moisture is absorbed by plants both through the soil and the surface of the leaves. The microclimate in the greenhouse saturated with moisture is loved by people from moist subtropics – for example, cucumbers. Water flows through sprinklers. Again, a plastic bottle with holes made to fulfill the function of a sprinkler helps the craftsmen to reduce the price of rain watering.

Ground sprinkling

This design of an automatic irrigation in a greenhouse for installation is similar to a drip. Differences – pipes are embedded in the soil, and instead of droppers, irrigation is carried out by spray nozzles – sprinklers. A mandatory requirement for automatic irrigation by the method of soil irrigation is the presence of a pressure in the system of at least 2 atmospheres. Cons – in case of malfunctions, it is necessary to open the entire system hidden in the ground to detect them.

Greenhouse aerial watering

Easy-to-maintain and install auto-irrigation method similar to above-ground irrigation. The difference is in the place where the pipes are laid – here they are located on top, under the ceiling of the greenhouse. A filter is required, which prevents clogging of the mouths of nozzles that turn water into tiny droplets of moisture. The pressure requirements in the automatic irrigation system are the same – from 2 atmospheres, therefore, an additional pump may be required.

Greenhouse Intra Soil Irrigation System

An economical way to autowire in terms of water consumption. Pipes, hoses, humidifiers made of porous material are located below the arable horizon. Moisture is absorbed due to the absorbing properties of the soil and quickly enters the root systems of plants. Intra-soil autowatering is not demanding on pressure, water can flow by gravity. The price of such an autowatering is higher compared to the rest. Advantages – keeping the fertile soil layer moist, no damage to the soil structure.

Bottle method for surface subsoil irrigation:

  1. Cut off the bottom of the bottle if you dig it in with the neck.
  2. Make holes to be dug in the ground..
  3. Dig the resulting structure close to where the plant will be or between two.
  4. Fill the container with water.

Ready-made automatic irrigation system in the greenhouse

Now autowatering is available not only to large agricultural enterprises, but also to mere mortals – summer residents. It can be ordered from the catalog and bought in an online store, or an ordinary horticultural. The final cost reflects the delivery price from the store and components for self-assembly, the type of system chosen, the size of the greenhouse, the number of plants.

How to choose autowatering

  1. Decide which autowatering you need – drip, rain or subsoil. In mixed plantings of crops that love dry and humid air, drip irrigation systems for a greenhouse or subsoil are better. If weed control is not to your liking, then give preference to the drip.
  2. Make a plan for the greenhouse – measure the size of the beds, develop a planting plan, then calculate the necessary amount of material to create automatic irrigation, if you will do it yourself, or devote the installation organization to your plans.
  3. Decide whether you need to fully automate irrigation in the greenhouse or whether it will be manually controlled at the starting point of the water supply. The final price of autowatering, as well as the amount of time that can be devoted to other, no less useful things, depends on this..
