Indoor Growing Basics: Equipment and Environment

This guide provides educational information about indoor cannabis cultivation techniques. Growing cannabis may be illegal in your jurisdiction. Always verify local laws and regulations before acquiring equipment or seeds for cultivation purposes.

Indoor cultivation allows precise control over the growing environment. This guide covers the fundamentals of equipment selection and environmental management.

Essential Equipment

Lighting: - LED grow lights are the current standard (efficient, lower heat output, long lifespan) - 100W suitable for 1-2 plants, 200-400W for 4-6 plants - Light distance varies by manufacturer — follow specific recommendations

Enclosure: - Grow tents provide a contained, reflective environment - 60x60cm for 1-2 plants, 120x120cm for 4-6 plants - Reflective interior surfaces maximize light efficiency

Ventilation: - Inline fan for air exchange (prevents heat buildup, supplies fresh CO2) - Carbon filter for odor management - Oscillating fan for air circulation (strengthens stems, reduces mold risk)

Containers: - 11-20 liter fabric pots are widely recommended - Fabric pots improve root aeration compared to plastic

Measurement tools: - pH meter (maintaining correct pH is critical for nutrient uptake) - Thermometer and hygrometer (temperature and humidity monitoring) - Timer for light schedule automation

Light Schedules

Vegetative stage: 18 hours light / 6 hours dark (18/6) Flowering stage: 12 hours light / 12 hours dark (12/12) Autoflowering varieties: 18/6 or 20/4 throughout — no schedule change required

The transition to 12/12 triggers flowering in photoperiod plants. Plants typically increase 50-100% in height during the first weeks of flowering (the "stretch").

Growing Media

Soil: - Pre-fertilized soil provides nutrients for the first 3-4 weeks - More buffering capacity — forgiving of small errors - Water when the top 2-3cm feels dry - Target pH: 6.0-7.0

Coco coir: - Inert medium requiring nutrient supplementation - Faster growth rates than soil - Requires more frequent watering - Target pH: 5.5-6.5 - Typically requires calcium-magnesium supplementation

Plant Nutrition

Cannabis requires three primary macronutrients (N-P-K): - Nitrogen (N): Higher demand during vegetative growth - Phosphorus (P): Higher demand during flowering - Potassium (K): Consistent demand, increases during flowering

A two-part or three-part nutrient system covers these needs. Most manufacturers provide feeding schedules. Starting at 50-75% of recommended concentration reduces the risk of nutrient burn.

The Growth Cycle

  1. Germination (1-5 days) — seed sprouts
  2. Seedling (1-2 weeks) — first true leaves develop, maintain 65-70% humidity
  3. Vegetative (3-8 weeks) — structural growth, 18/6 light
  4. Flowering (7-12 weeks) — flower development, 12/12 light (photoperiod)
  5. Harvest — timing determined by trichome maturity (examined with magnification)
  6. Drying (7-10 days) — controlled environment: 18-22C, 55-60% humidity
  7. Curing (2+ weeks) — storage in sealed containers with periodic air exchange

Common Issues

  • Overwatering: The most frequent mistake. Allow the medium to partially dry between waterings.
  • pH imbalance: Outside the correct range, plants cannot absorb nutrients regardless of concentration.
  • Nutrient excess: More is not better. Yellowing leaf tips indicate overfeeding.
  • Light stress: Excessive light intensity causes bleaching. Maintain manufacturer-recommended distances.
  • Premature harvest: Patience yields better results. Most beginners harvest too early.
