Category: dehumidifier 👁 826 👍 20 ★★★★☆4.4

Proper watering and adequate plant spacing, having well-drained floors, warming plants, moving air and venting moisture are ways to reduce humidity in greenhouses. The least expensive method is to keep the greenhouse dry, especially going into the night, when the temperature drops.

Although, what is the best humidity for a greenhouse?

50-70% relative

No less, what dehumidifier does Consumer Reports recommend? CR's take: The Honeywell TP30WK tops our ratings of small-capacity models, which means it can remove 30 pints of moisture per day and can help dry out small, damp spaces. It earns a Very Good rating in our noise tests and is the only dehumidifier in our current ratings that snags an Excellent in our cool-room tests.

One may also ask, how big of a dehumidifier do I need for my grow room?

As an example, if you have 20 plants in your grow system, you have to feed at least 1 gallon of water to each of them each day. Verdict – you need to have a dehumidifier that is able to remove 160 pints of moisture from the air within a time span of 24 hours.

Why is my greenhouse full of condensation?

Condensation means that there is too much water in the air to remain in the vapor state. So it falls out and forms water droplets on surfaces inside greenhouse that are at or below the dew point. These cold surfaces are aluminum frame, piping, door knobs, roof and plants.
