Botrytis is a very common disease in cannabis growing. This fungal pathogen can attack many crops but it is especially dangerous for dense cannabis buds. This destructive mold is called Botrytis cinerea. With cannabis, the risk is much higher. The thick buds hold moisture and create a humid space inside. This trapped vapor builds up […]

Are you noticing a gray mold growing on your strawberries or flowers in your greenhouse or garden? This fungus is a common disease and you can see this infection developing on the plants everywhere. It can quickly ruin the crops if you do not manage it properly. Scientists call this Botrytis. It attacks many crops

Humidity is one of the most important yet tricky factors in greenhouse management. A moderate level of humidity helps plants grow strong, promotes nutrient uptake, and keeps leaves from drying out. But when humidity goes too high for too long, it turns into a silent threat — causing fungal diseases, mold, blossom-end rot, and even

Creating the right environment inside a greenhouse is a delicate balance between temperature, humidity, and airflow. These two factors—temperature and humidity—directly affect plant growth, disease resistance, and yield potential in your greenhouse. Understanding how they work together helps growers maintain optimal conditions year-round, ensuring that crops thrive regardless of outside weather. Ideal Greenhouse Temperature and

Humidity is one of the most critical factors influencing plant growth, health, and yield. In U.S. greenhouses, factors such as dense planting, frequent irrigation, seasonal rainfall, and limited ventilation can push relative humidity (RH) up to 90% or higher.  At first glance, high humidity may seem harmless—after all, plants need moisture to thrive. However, sustained

Maintaining the right humidity in a greenhouse is core to crop health, yield, and post-harvest quality. Too much moisture accelerates fungal and bacterial disease, slows transpiration and nutrient uptake, and degrades structures and equipment. Dehumidifiers are a practical tool in the greenhouse manager’s toolbox — not a cure-all, but an effective mechanical method to remove
