Temperature and Microgreens

Temperature plays a very important role in growing healthy microgreens. Getting it right will help your seeds germinate evenly and grow strong.

Ideal Growing Temperature

The best temperature range for most microgreens is:
18°C to 24°C

Keep in mind that this can vary depending on the type of plant, the growth stage, and the season.

• Cooler-loving microgreens: kale, lettuce, peas

• Warmer-loving microgreens: basil, rocket, amaranth

Growing in Hot Weather

During summer, temperatures can easily rise above 30°C, which can stress your microgreens.

To protect them:

• Keep trays in an air-conditioned space when it gets too hot

• You can place them outside in the early morning sun or late afternoon light

• Avoid strong midday heat

As a general rule:
Once temperatures go above 27°C, it’s best to bring them into a cooler space.

Watering in Warm Conditions

Microgreens may need a little more water in warm weather, but be careful:

• Keep the soil moist, not wet

• Avoid overwatering, as this can lead to mould and poor growth

Final Tip

A stable, moderate temperature will always give you better results than extreme heat or cold. Keep your microgreens comfortable, and they will reward you with strong, healthy growth.
