Mulching with organic materials like straw or wood chips reduces evaporation and helps maintain soil moisture levels. Watering plants during cooler parts of the day, such as early morning or late evening, further minimizes water loss.

Integrated Pest Management (IPM)

What Is IPM?

Integrated Pest Management (IPM) is a strategic approach that combines biological, cultural, physical, and minimal chemical tools to manage pests in an environmentally sensitive manner.

Benefits

This approach significantly reduces pesticide use, lowering chemical exposure for both plants and farmworkers. It also promotes sustainable, long-term pest control, minimizing the risk of pests developing resistance.

Techniques

Introducing beneficial insects like ladybugs and predatory mites helps control pest populations naturally. Physical barriers such as row covers protect crops without chemicals. Organic pesticides, derived from natural sources, are used sparingly and only as a last resort.

Energy Efficiency

Importance

Indoor cannabis cultivation can be energy-intensive, primarily due to lighting, climate control, and ventilation needs. Improving energy efficiency reduces operational costs and the carbon footprint of production.
