Light cycle optimization for coco cultivation

## Introduction

Coco cultivation of cannabis requires special attention to the light cycles, as coco is a fast reacting medium. This enables precise control of plant growth through targeted light adjustments.

## Light cycles for coco cultivation

### Vegetation phase

- Light cycle**: In the vegetation phase, a light cycle of 18 hours of light and 6 hours of darkness (18/6) is recommended. This supports healthy, stable growth and promotes dense leaf development.

- **PPFD values**: The photosynthetic photon flux density (PPFD) should be between 400 and 600 µmol/m²/s to maximize photosynthesis without light stress.

- **Light spectrum**: A higher proportion of blue light (6500K) is ideal for the vegetative phase as it promotes compact growth and root development.

### Flowering phase

- **Light cycle**: During the flowering phase, the light cycle should be switched to 12 hours of light and 12 hours of darkness (12/12) to induce flower formation.

- **PPFD values**: Increase PPFD levels to 600-1000 µmol/m²/s to maximize flower production and promote bud density.

- **Light spectrum**: A more reddish spectrum (3000K) is beneficial at this stage as it supports flower formation and resin production.

## Optimization of the light distance

- Vegetative phase**: The distance between the LED lights and the plant tips should be around 30 to 45 cm, depending on the power of the lights and the PPFD value.

- Flowering phase**: During the flowering phase, the distance can be increased to 45 to 60 cm to prevent light burn and ensure even light distribution.

## Summary

The targeted adjustment of light cycles and intensities in coco cultivation is crucial for achieving maximum yield and healthy plants. By taking into account the specific requirements of the vegetation and flowering phases, growers can significantly improve their harvest results.

## Pro Tips

- Use timers for precise light cycles.

- Check the PPFD values regularly.

- Adjust the light distance in the event of changes in growth.

- Ensure uniform light distribution.

- Monitor the plant reaction to light adjustments.
