Stunted Growth in Greenhouses - remedies

You cannot leverage the climate outside, but by controlling the climate within a closed environment, you can create and consistently maintain the optimal conditions for growth.

Typically these conditions fall between 20°C / 68°F and 25°C / 75°F and no more than 80% humidity, even in tropical and subtropical areas.

It’s no secret that excess heat in a greenhouse can lead to numerous problems including stunted growth, burnt leaves, damaged fruit and even total crop failures. Lack of humidity is another contributing factor to crop problems. If the humidity is too low, the result is excessive transpiration and crop damage. If it is too high, the plants will be prone to attack by fungi and mold.

The good news is that all of the above have remedies; installation of heaters and circulating fans prevents cold spots and stratification of the greenhouse air, reducing the risk of condensation and the onset of wet-induced botrytis; extra exhaust fans generate additional ventilation to prevent extreme temperatures and ensure adequate CO2 concentrations; while high levels of humidity can be prevented with a combination of recirculation fans, extraction fans and heaters.
