Manual irrigation techniques for indoor cultivation

## Introduction

Hand watering cannabis plants in indoor cultivation requires precise techniques to ensure the growth and health of the plants. In this guide, you will learn how to determine water requirements, apply the correct watering technique and control the moisture in the substrate.

## Determine water requirements

The water requirements of cannabis plants vary depending on the growth phase, temperature and humidity. Observe the weight of the pots to determine when to water. A light pot indicates a lack of water, while a heavy pot contains sufficient water.

### Correct watering technique

- **Slow watering**: Pour the water slowly onto the surface to ensure even distribution and avoid waterlogging.

- **Aim at the roots**: Avoid watering directly on the plant. Concentrate on the area around the base where the roots are located.

## Control moisture

- **Finger test**: Stick a finger about 2-3 cm deep into the substrate. If it feels dry, it's time to water.

- Moisture meter**: Use a moisture meter to accurately monitor soil moisture.

### Ensure drainage

Good drainage is crucial to prevent root rot. Use pots with drainage holes and ensure that water can drain away freely. Make sure that water does not accumulate in saucers.

## Avoid common mistakes

- Overwatering**: One of the most common mistakes is overwatering. Look out for signs such as drooping leaves and limp roots.

- Underwatering**: Yellow or wilted leaves can indicate a lack of water. Check the weight of the pots regularly to avoid this.

## Pro Tips

- Water in the morning to prevent mold growth.

- Use rainwater to keep the pH stable.

- Maintain a constant room temperature to regulate the water requirement.

- Use clean, stale water to remove chlorine.

- Note casting times and quantities to recognize patterns.
