Polycarbonate greenhouses don’t yellow with age, but they do get dirty and this grime can reduce the light transmission by 10% or more. If you have an 8mm polycarbonate greenhouse, it is usually rated at 80% light transmissivity, and will block UV rays that burn plants. You can also purchase a solar power meter to keep track of this: direct sunlight is 360 BTU per square foot per hour and under 6mm plastic, should be around 327 BTU per square foot per hour.

However, this transmission rate will degrade as your plastic ages and turns yellow. The standard plastic cover is 6mm, which is durable and usually rated with 91% light transmission per layer. Greenhouse coverings come with a light transmission rating. We’ve already talked about limiting light intentionally with shade cloth, but you may not realize that you are accidentally limiting the amount of light your plants are getting without even noticing. If you purchased a humidity monitor, you will be able to see what the humidity is when dew is forming on your plant’s leaves, which is what you want to avoid. In the winter, consider using a low-tech heat sink like barrels of water to stabilize temperature.
DROPOVER GREENHOUSE WINDOWS
Ventilate the greenhouse during the hotter part of the day so it does not have a temperature spike, and make sure cooling fans are turned off and ventilation windows are closed well before night or cloud cover to prevent excessive cooling.

You could purchase a high-tech monitoring system, but for a hobby gardener, the real secret is maintaining stable temperatures. Rapid temperature changes in a greenhouse can seriously damage plants, especially plants like tomatoes and cucumbers, which are common greenhouse fare. It is ideal for anyone with limited space to plant.
DROPOVER GREENHOUSE FULL
This is not a full greenhouse but acts very similar in that it protects plants from weather and pests. The Drop-Over Greenhouse measures 4.5 x 4.5 and has enough space to cover a raised garden bed or quite a few potted plants. However, the air can only hold so much water, and that ability is decreased as the temperature drops. The Greenlife Large Drop Over Greenhouse has been developed to drop-over the Greenlife Large Garden Bed. The Gardenline Drop-Over Greenhouse was available from Aldi last May for 24.99. As plants grow they take in water through their roots, and then transpire that water into the air around them. Humidity is a natural part of the greenhouse water cycle.
