Why Ventilate your Greenhouse?

Greenhouse Cooling and Humidity Control

Controlling greenhouse humidity with some ventilation system is a must in just about any climate.  Even in cooler climates, greenhouse temperatures can reach extreme levels.  Your plants are more likely to die in a greenhouse from excessive heat than cool temperatures.

Pests and Disease Prevention

Proper greenhouse air circulation is also critical for healthy plants. By rolling up your side curtains you allow stale air to get pushed out of your greenhouse leading to healthier plants with fewer disease and pest problems.  Many common greenhouse pests and diseases thrive on stale and humid air.  Rolling up your sidewalls will allow air to circulate, naturally reducing incidences of these common problems.

Better Pollination

Growing in a greenhouse without natural air circulation can cause poor pollination of your plants.  A breeze naturally sends pollen around your greenhouse so you can avoid the hassle of hand-pollinating every plant.  If you are noticing poor pollination or poor fruit setting, this is a sign that you may need to be increasing the airflow into your greenhouse.


Keeping Your Greenhouse Ventilated

During the hot summer months its critical to keep your greenhouse well ventilated.  In our area at the southern coast of North Carolina we get average highs in the lower 90s with high humidity. Without proper greenhouse ventilation temperatures inside can easily exceed 115°.  To keep your plants cool during periods of high heat we simply just roll up our sidewalls and keep both end wall doors open.  This allows air to naturally keep our greenhouse cool and our plants safe from excess heat.

Pollination Information

Pollination of Greenhouse Sidewall Ventilation Crank ():



It is generally recommended to wait to fertilize a bare root plant until it has been established in the ground and is actively growing. This can vary depending on the type of plant and the growing conditions, but it is generally best to wait at least a few weeks to a few months after planting.

During the first year, you should focus on providing the plant with the right amount of water, sunlight and soil to help it become established. Once the plant has become established and is actively growing, you can begin to fertilize it.

You can use a balanced, all-purpose fertilizer or one that is specifically formulated for the type of plant you have. Be sure to follow the instructions on the fertilizer package and apply it at the recommended rate.

It is also important to note that over-fertilizing can be harmful to plants, so it's always best to error on the side of caution and start with a lower amount of fertilizer and increase as needed.
