Temperature and humidity are two key characteristics within the environment which will determine your sprouts and plants growth levels and overall health.
They work in tandem, so the higher your temperature is, the higher your humidity needs to be.
The ideal temperature and humidity for germination are:
- Temperature: 70 degrees Fahrenheit range is ideal (with a maximum of 85 degrees Fahrenheit)
- Humidity: 65-75% humidity
Higher or lower ranges can cause delays in germination.
Once your plants are well established:
As the plant continues to grow, the range in temperatures and humidities have a larger range but should be ideally maintained at:
Temperature: 68-82 degrees Fahrenheit range
Humidity: 50-70% humidity
Different varieties, different needs:
Be aware of the specific needs of the species you are growing. For example, leafy greens do best in cooler temperatures, while fruiting crops do better in more temperate environments. You can check the Plant Book in the App for variety-specific information.
Our master grower tip: When your lights go off on the Gardyn, it is important to maintain minimal temperature differences between day and night- ideally no more than 5 degrees Fahrenheit.
Understand more about the impact of temperature and humidity on your plants growth:
Temperature and humidity work together to control water uptake, nutrient assimilation and distribution, and photosynthetic potential.
They can drastically affect a plant’s life cycle, and too below or above the suggested ranges can cause issues in germination, growth and expedite a plants life cycle by triggering bolting (going to seed).
In terms of temperature, the biochemical process for growth depends on it being kept within an ideal range for photosynthesis to occur at optimal rates. If temperatures are above or below this range, the processes will slow down, ultimately slowing down the overall development of the plant.
When conditions are too humid, the plant can’t make water evaporate or draw nutrients eventually promoting the growth of mold and bacteria, conditions like root or crown rot and invite the presence of pests, such as fungus gnats.
While plants can survive in a range of temperatures and humidity levels depending on the specific needs of the species, and the life stage it is in, it is important to have a balance with steady uptake and photosynthesis, in levels that complement each other.
