Growing Weed in a Closet: A Quick Guide

Growing weed in a closet presents an opportunity for enthusiasts to cultivate high-quality plants discreetly and efficiently. In this comprehensive guide, we will delve into the intricacies of closet cultivation, providing detailed insights and practical tips to ensure successful outcomes.

Advantages of Growing Weed In Closet

Growing cannabis in a closet offers several distinct advantages:

  1. Cost-Effectiveness: Unlike outdoor or tent cultivation, a closet setup requires minimal investment in specialized equipment. This makes it a budget-friendly option for novice growers.
  2. Discreetness: Concealed within a closet, cannabis plants remain hidden from view, offering privacy and security, especially in regions where cultivation is restricted.
  3. Controlled Environment: Closet cultivation enables precise control over environmental factors such as temperature, humidity, and light exposure, facilitating optimal growth conditions.

Factors to Consider

Closet Space

Effective lighting is paramount for successful closet cultivation. LED lights are recommended for their energy efficiency, customizable spectrum, and minimal heat emission. Proper light spectrum adjustment throughout the plant’s growth stages is crucial for maximizing yield.

Grow Medium

Growers can choose between hydroponic and soil-based mediums, each with its own advantages and considerations. Hydroponic systems offer faster growth and nutrient precision but require meticulous maintenance to prevent mold and fungus. Soil-based setups provide a more natural environment and require less technical expertise.

Ventilation and Airflow

Proper ventilation is critical to maintain optimal air quality and prevent issues such as mold and stagnant air pockets. Utilizing small fans strategically placed within the closet promotes airflow and ensures consistent temperature and humidity levels.

How To Grow Weed In Your Closet

Step 1: Closet Preparation

  • Clean and sanitize the closet space to eliminate any potential contaminants.
  • Apply reflective material such as mylar film or white paint to enhance light distribution within the closet.

Step 2: Lighting Setup

  • Install LED lights with customizable spectrum options to accommodate different growth stages.
  • Ensure proper spacing and positioning of lights to provide uniform coverage across all plants.

Step 3: Ventilation Installation

  • Install small fans to promote airflow and prevent stagnant air pockets.
  • Incorporate carbon scrubbers to mitigate odors and maintain discretion.

Step 4: Grow Medium Selection

  • Choose between hydroponic or soil-based mediums based on personal preference and experience level.
  • Ensure adequate drainage and aeration to prevent waterlogging and root rot.

Step 5: Planting and Maintenance

  • Select suitable cannabis strains that fit within the available closet space and growth constraints.
  • Monitor and adjust environmental variables such as temperature, humidity, and watering frequency regularly.
  • Implement training techniques such as low-stress training (LST) to optimize plant growth and maximize yield potential.

Germination Stage

  • Maintain darkness, warmth, and moisture to facilitate seed germination.
  • Keep soil consistently damp during this initial growth phase.

Vegetative Stage

  • Maintain temperatures between 75°F to 80°F (24°C to 29°C) with humidity levels between 60% to 70%.
  • Provide ample airflow and light exposure to encourage healthy vegetative growth.

Flowering Stage

  • Maintain temperatures between 72°F to 78°F (22°C to 25.5°C) with lower humidity levels between 45% to 55%.
  • Minimize light exposure during the dark period to promote bud development.

Harvesting and Curing

  • Harvest cannabis buds when trichomes are fully developed and milky in appearance.
  • Cure harvested buds in a controlled environment with proper ventilation and humidity levels to preserve flavor and potency.


In conclusion, cultivating cannabis in a closet offers a viable and rewarding option for enthusiasts seeking discretion and control over their growing environment. By adhering to best practices and implementing the guidelines outlined in this comprehensive guide, growers can achieve optimal results and enjoy a bountiful harvest of high-quality cannabis buds.


Q: Can I use regular household lights to grow cannabis in a closet?
A: No, regular household lights are not suitable for cannabis growth as they lack the specific spectrum needed for plant photosynthesis.

Q: How often should I water my cannabis plants in a closet?
A: Water your cannabis plants when the top inch of the soil feels dry to the touch, typically every few days depending on environmental conditions.

Q: Do I need a carbon dioxide supply for my closet-grown cannabis plants?
A: While carbon dioxide supplementation can enhance growth, it’s not necessary for successful closet cultivation. Proper ventilation and airflow are more crucial for healthy plant development.

Q: Can I grow cannabis in a small closet with limited space?
A: Yes, you can grow cannabis in a small closet, but you’ll need to choose compact strains and implement training techniques to control plant size and optimize space utilization.

Q: How long does it take to harvest cannabis grown in a closet?
A: The time to harvest cannabis grown in a closet varies depending on the strain and environmental conditions, but it typically ranges from 8 to 14 weeks from seedling to harvest.
