Want to go on vacation without neglecting your cannabis crops? Automatic irrigation is what you need

Summer is a time when many of us enjoy well-deserved vacations away from home. However, for cannabis growers this can be a challenge, as watering plants during this period can become a real headache.

Fortunately, there is an incredible solution: automatic watering. In this post, we’ll tell you about the various automatic watering options that exist so that you can keep your cannabis crops hydrated while you’re on vacation.

Types of automatic irrigation

There are a wide variety of automatic irrigations, with each type being better or worse for the type of cannabis you’re growing. These are the main ones:

Automatic sprinkler irrigation

Automatic sprinkler or drip irrigation is an excellent choice for keeping your plants watered efficiently. You can buy commercial models or even set up your own system with a faucet, a water timer, drippers or sprinklers, and tubing.

The best thing about this option is that you can fully automate watering by pre-testing to determine the proper duration and intervals of watering. This way, you can ensure that your cannabis crops receive the right amount of water daily without the risk of waterlogging or underwatering.

Automatic gravity irrigation

Another alternative is automatic gravity irrigation. You can combine it with a water timer and a float system to ensure that the water tank never runs empty.

If you choose this option, be sure to control the amount of water reaching your cannabis, making sure to avoid excessive continuous dripping. Also, by storing the water beforehand, you will allow the chlorine to degrade, thus benefiting the micro-life of the soil.

Capillary irrigation

This is a technique that allows you to supply water slowly to the plants, avoiding water stress during your absence.

A common method is to use clay cones buried in the substrate, which will gradually supply water from a bottle, carafe or canister. These cones act as a sort of drip mechanism, providing the plants with the amount of water necessary for their survival.

Absorbent polymers

Polymers or hydrogels are capable of absorbing water and releasing it slowly when plants need it. These materials are widely used in agriculture and are an interesting option to keep your plants hydrated during short vacations.

Watering with bottles or inverted carafes

If you are looking for an economical, but less efficient option, you can resort to watering with inverted bottles or carafes. Simply make a small hole in the cap of the bottle or carafe by heating a needle. Then, fill the container with water, place the stopper and turn the bottle upside down.

Gravity will cause the water to fall through the hole, and the size of the hole will determine the watering rate. You can adjust the water flow by placing a cotton ball inside the stopper or by using several bottles per plant.

Pre-test to find the right setting to ensure prolonged watering, but without over-watering.

What are the benefits of automatic irrigation?

Automatic watering offers numerous benefits and is especially useful if you need to go on vacation without worrying about your cannabis crops.

Here are some of its most relevant benefits:

You save time and effort

By automating the watering of your plants, you can enjoy your vacation without worrying about manually watering your crops every day.

Increased watering efficiency

Automatic irrigation allows you to provide your plants with the right amount of water constantly, avoiding both waterlogging and lack of irrigation.

Optimizes yields

By ensuring a constant supply of water, automatic watering helps to maximize the yields of your cannabis crops.


Automatic watering is an efficient solution for keeping your cannabis crops hydrated while you’re away from home. Whether you opt for drip irrigation, gravity irrigation, capillary irrigation, absorbent polymers or inverted bottle irrigation, be sure to adjust the system according to the specific needs of your plants.

Remember to pre-test and find the right balance between prolonged watering and the right amount of water to avoid problems with waterlogging or dehydration.
