Maintaining the right temperature and humidity levels is crucial for optimal growth and health of your indoor cannabis plants. Here’s a quick guide on the ideal conditions you should aim for:

Optimal Temperature For Growing Cannabis Indoors

For indoor cannabis cultivation, the ideal temperature range during the day (light hours) is between 68°F and 77°F (20°C to 25°C). During the night (dark hours), temperatures can be slightly cooler but should not drop below 64°F (18°C). It’s important to avoid drastic temperature changes, as this can stress the plants and lead to various growth issues.

Optimal Humidity For Indoor Cannabis Growing

Humidity levels should vary depending on the stage of growth:

  • Seedling Stage: Maintain humidity around 65-70%. High humidity is essential during this early stage to support the development of healthy roots.
  • Vegetative Stage: Gradually reduce humidity to about 40-60%. This range encourages strong vegetative growth without fostering mold or mildew.
  • Flowering Stage: Lower humidity further to between 40-50%. During the last 1-2 weeks before harvest, aim for 30-40% humidity to help prevent mold and increase resin production.

Proper management of temperature and humidity not only supports robust growth but also enhances the quality and potency of your cannabis.
