Hydroponic cannabis harvesting: specific techniques and tips

Introduction

Harvesting hydroponically grown cannabis requires special attention to maximize the quality and potency of the buds. This guide presents specific techniques and tips for harvesting in a hydroponic system.

Determine harvest time

The optimal harvest time is crucial to the quality of the final product. In hydroponic systems, plants often mature faster than in soil, so close observation is important.

Examine trichomes

• Clear: Immature, low THC content.
• Milky**: Highest THC content, ideal harvest time.
• Amber**: THC begins to break down, sedative effect.

Use a microscope or magnifying glass with at least 60x magnification to check the trichomes.

Pruning and trimming plants

Preparation

• Tools: Sharp, clean shears or trimmers.
• Hygiene: Wear gloves to avoid contamination.

Cutting techniques

• Wet trimming: Trim directly after cutting. Advantage: Faster drying.
• Dry trimming**: Trim after drying. Advantage: Better preservation of terpenes.

Drying the flowers

Conditions

• Temperature**: 18-22°C.
• Humidity: 45-55%.
• Air circulation: Gentle, without direct airflow on the flowers.

Method

• Hanging: Hang whole plants or branches upside down.
• Duration: 7-14 days, until the stems crack slightly when bent.

Carry out the curing process

Procedure

• Containers**: Use airtight jars.
• Humidity: 55-65% relative humidity in the jar.
• Aerate: Open daily for 15 minutes for the first week, then weekly.
• Duration**: At least 2 weeks, optimally 4-8 weeks.

Conclusion

Harvesting hydroponically grown cannabis requires precise techniques and careful follow-up. The quality of the flowers can be maximized by determining the exact time of harvest, correct cutting and trimming as well as controlled drying and curing.

Pro Tips

• Use a hygrometer to monitor the humidity during drying.
• Make sure the drying environment is dark to prevent the breakdown of cannabinoids.
• Avoid direct air currents on the flowers to prevent uneven drying.
• Use Boveda packs to keep the humidity constant during curling.
• Note the harvest time and conditions to optimize future harvests.
