What are the best conditions to grow Hydroponic Bell Peppers?


Just like tomatoes, the humidity levels required to grow peppers in hydroponics are generally high, i.e., from 55 to 65%. The humidity level should not be higher than this level. You can consider a range of 60 – 80% of humidity, but we won’t recommend it for growing pepper plants. If the humidity level increases than the suggested level then it may lead to the formation of deformed fruits.

pH Value

In Hydroponic Farming pH value plays an important role in determining the health of the plant. The pH value for hydroponic bell peppers should be around 6.0 to 6.5. If it is lower or higher than this level then the plant won’t intake essential minerals from the water solution. Hence leading to unhealthy plants. Make sure pH remains the same and does not fluctuate very often to preserve the plant development at a consistent rate and proper pH.


Bell pepper plant needs a minimum of 14 to 18 hours of light every day for stable development. You can also use artificial lights such as HID or lead grow lamps that can also be used for indoor plant heating. For commercial growers, this type of lighting is best suited.


A specific temperature range needs to be followed for growing peppers. The temperature at night should be 18°C or more than that. The day temperature should be around 30°C. Never let the temperature be more than 34°C to maintain the growth of the plant. Even in a warmer climate, the temperature should be less than 35°C, else the flowers of the plant will fall. 


One should use a nutrient regimen to feed the bell pepper plant that benefits vegetative growth. Mix one-part nutrient solution in water for bell pepper preparation. As the plant reaches the flowering stage, lessen the amount of nitrogen and switch to another one-part nutrient product. Adding potassium and phosphorus will enhance the production of Bell Pepper’s fruits, leaves, and flowers.

Plant Spacing

A bell pepper plant needs proper spacing for its full development. Keep a distance of 18 to 24 inches between the plants for the finest spacing condition. You can also place them closer, but there will be a potential risk of shaded lighting.
