Automatic and manual cannabis watering: our professional equipment

We all know the importance of watering plants, as it is essential for their growth and survival, particularly because water plays a role in photosynthesis and is how many nutrients are delivered. Here you’ll find everything you need for watering cannabis, with equipment that has been selected for its quality and is offered on our website at discount prices so everyone has the chance to give the best care to their cannabis plants. Beginners or professionals, whether you prefer manual or automatic watering, you’ll find excellent tools here to successfully water your cannabis.

Manual watering: get everything you need to cherish your plants

If you enjoy taking the time to water your plants yourself (ever heard of plant therapy?), you’ll find all the equipment you need on our site to take care of your cannabis. During the early stages of cannabis growth, it’s best to avoid overly powerful watering, which could hinder proper plant development. Later, you can opt for instinctive watering for more flexibility or measure each liter for more control.

Plant watering: A wide range of accessories for the grower

At GB The Green Brand, we don't skimp on variety; that’s why we offer a well-stocked selection of watering equipment for weed, so you can get everything you need or complete your irrigation system. Remember, if you have any doubts or questions, you can contact our customer service, who will guide you as best as possible.

Flexible Hose - 16 mm

This polyethylene hose measures 16 mm in diameter and is available in 8 m or 25 m lengths. It is suitable for many irrigation systems and does not require additional equipment for installation.

Telescopic Watering Lance

To water with precision and reach all areas that need watering, consider this telescopic lance, which is easy to use and available at a competitive price. You won’t overlook any of your plants!

Measuring Cup - 1 L

Here’s the grower’s must-have: the measuring cup. This plastic measuring cup has a 1-liter capacity and allows you to measure and gauge the amounts of nutrients and water to provide your plants, ensuring the best possible growing conditions.

Foliar spraying to prevent deficiencies and diseases

To prevent deficiencies and diseases that could harm cannabis plants, you can use the foliar spraying method. Instead of watering the roots directly, you’ll apply water to the leaves, so they receive the necessary nutrients, particularly in cases of deficiency. This method also helps to grow denser plants.

PumPro 2 L Pressure Sprayer

This pressure sprayer from PumPro has a 2-liter capacity and can regulate the water flow. It features a 360º rotating jet, allowing you to reach all areas needing watering, and is easy to handle and use.

The importance of using quality water for cannabis irrigation

It’s crucial to use water that’s free of bacteria, fungi, chlorine, and limescale, which could damage or even kill cannabis plants. For this reason, it’s best to avoid using tap water and instead opt for pure water, like reverse osmosis water, which is ideal. This way, you’ll ensure you don’t infect, infest, or harm your plants.

5-Stage Reverse Osmosis Filter

Use this 5-stage reverse osmosis filter with filters that remove all elements that could be harmful to cannabis and are often found in water. You can also choose the model with a tank to always have water available.

Automatic watering: precise nutrition for a prolific harvest

Choosing automatic cannabis watering helps you avoid excessive worry about water supply in your grow, while saving time, especially if you have large crops where individual watering is not feasible. This way, you ensure your plants receive the regular hydration and water supply they need. You can schedule and adjust the watering frequency to suit your crops, along with the amount of water delivered.

Explore our range of drippers for automatic watering

We offer drippers, perfect for automatic weed watering. They provide a drip irrigation system for cannabis, which is especially useful for aeroponic watering. Drip irrigation helps save on water bills while delivering abundant harvests.

Medusa Dripper 12 Outlets 16 mm

The Medusa Dripper connects to 16 mm diameter tubes. It has 12 outlets, which you can place at 12 different pots to ensure they get regulated water supply. You can also install a timer to schedule cannabis watering.

Hydroponic Watering: get our professional tools for your drip system

In soil, cannabis requires a pH between 6 and 7. However, with hydroponic or coco watering, the pH will be slightly lower, between 5.5 and 6.5. Make sure to provide cannabis with drip irrigation at the appropriate pH for the soil, which can be easily done using the professional equipment we offer on our site:

GSE Watering Timer

To regulate, control, and schedule cannabis drip irrigation, consider getting a timer! This will ensure your plants get the necessary water even in your absence or while you sleep. You’ll soon appreciate the quality of your harvests.

Flexible Reservoirs

To ensure you never run out of water, you can get a reservoir for storage. These flexible reservoirs come in different sizes, namely 100, 250, 500, and 1000 liters. Completely sealed, they help prevent algae growth.

Water Master Pump

The Water Master Pump is available in different water pump capacities, measured in liters per hour (L/h). These range from 800 to 11,000 L/h, making it perfect for professional growers who need large amounts of water, especially since it is particularly durable.

Drip irrigation for cannabis: all the benefits

Drip irrigation allows you to provide cannabis with water regularly, while avoiding overwatering. It is also an excellent option if you need to be away from home for a few days and can’t ask someone to take care of your cannabis plants, while saving water thanks to greater control and precision.

How to avoid overwatering cannabis plants?

Overwatering cannabis can lead to nutrient deficiencies and diseases that may be fatal for the plants. To avoid overwatering, first observe the appearance of your plants, which you should regularly monitor (they shouldn’t appear droopy), as well as the soil or fertilizer, which should be dry after several days without watering. Also, consider using containers with drainage holes at the bottom or applying draining materials like perlite or vermiculite.
