Winter (December – February): The Indoor Season
Outdoor growing is impossible, making this the prime season for indoor cultivators.
- Indoor Growers: The main challenge in winter is low humidity and cold temperatures. You may need to use a humidifier to keep your RH in the optimal range (40-60%) and a small heater (used safely outside the tent and connected to a thermostat) to keep the root zone from getting too cold at night when the lights are off.
- Outdoor Growers: This is harvest time! Keep a close eye on the weather. An early frost can ruin a crop. Be prepared to harvest quickly if temperatures are predicted to drop below freezing. Also, watch for morning dew, which can contribute to bud rot. Gently shaking plants in the morning can help.Indoor Growers: Enjoy the naturally cooler and less humid air. Your environmental controls won’t have to work as hard. This is an excellent time to start a new indoor cycle, as it’s easier to maintain ideal conditions.

- Outdoor Growers: Ensure your plants get plenty of water, especially during heatwaves. Water deeply in the early morning to reduce evaporation. Watch for signs of pests like spider mites and caterpillars, which are most active in summer.Indoor Growers: This is the most challenging time for indoor climate control. Your air conditioner and dehumidifier will be working overtime. Ensure excellent air circulation to prevent mold and bud rot, especially during the flowering stage when humidity needs to be below 50% RH. Consider running your lights at night to reduce heat during the day.
Fall (September – November): Harvest Time & Cooler Temps
The days get shorter and cooler, signaling the end of the outdoor season and a more manageable indoor environment.

- Outdoor Growers: Start hardening off your clones in late spring. Gradually expose them to outdoor sunlight and temperatures over 7-10 days, bringing them in at night until the risk of frost has completely passed (typically late May in Michigan).Indoor Growers: Spring often brings moderate humidity. This is a great time to manage your environment with minimal equipment. Ensure your ventilation is good to handle the transition to warmer days, and watch for outdoor pollen and pests that might try to get inside.
Summer (June – August): Heat and Humidity Management
Summer is peak growing season, but it brings challenges with heat and high humidity.
- Outdoor Growers: Ensure your plants get plenty of water, especially during heatwaves. Water deeply in the early morning to reduce evaporation. Watch for signs of pests like spider mites and caterpillars, which are most active in summer.Indoor Growers: This is the most challenging time for indoor climate control.

Adjusting your care routine based on the season is crucial for maintaining a healthy and productive grow, especially in a climate like Michigan’s. Whether you are growing indoors or outdoors, temperature, humidity, and light intensity change throughout the year, and your plants will notice. Here’s how to adapt.
Spring (March – May): The Growing Season Begins
This is the ideal time to start new clones for an outdoor season. For indoor growers, it’s a time of stable conditions.
