It is well known that growing plants in indoor systems can often produce plants of better quality and quantity, but many balances need to be made in the process of growing. Maintaining proper relative humidity is one of the important factors.
Indoor growing rooms must not only maintain relative humidity, but also pay attention to maintaining relative dryness. Therefore, the size of the dehumidifier is very important for the growing room. If you have the wrong calculation of the amount of dehumidification required for your growing room, then your growing room environment is either too dry or too humid. This is the basic knowledge of gardening, and none of these extreme scenarios is suitable for growing.
What you need to do is to make clear what size of suitable dehumidifier should be selected for your growing room.
The basic knowledge of the size of the grow room dehumidifier you need to know.
The dehumidification capacity of a dehumidifier is often reflected on the label of the machine, which is usually displayed as the "dehumidification capacity (pint/day)" under a certain working condition. This plays a key role in choosing a dehumidifier suitable for your growing room.
The following are some basic knowledge of growing room dehumidifiers.
Pint is a unit of water immersed from the air. When the dehumidifier works normally, it can remove a certain "pint" amount of water within any set time. Usually, this calculation is shown on the label of the machine in pints/day.
For example, if the dehumidifier has a label of 30 pints per day, it means that it can remove 30 pints of air moisture per day from the designated area.
At the same time, we can also convert the unit of pint/day to pounds/day. 1 pint is equal to 1 pound of water.
Working status of dehumidifier
What is the working condition of the dehumidifier? In short, it is the state of the dehumidifier running at a certain temperature and relative humidity. The dehumidification capacity of the dehumidifier is also different under different working conditions. For compressor dehumidifiers which use refrigerant, the lower the temperature, the lower the dehumidification capacity, the lower the relative humidity, and the lower the dehumidification capacity. The working conditions of common dehumidifiers are mainly divided into two types: Saturated working conditions (90℉/90%RH), AHAM working conditions (80℉/60%RH). The AHAM working condition is also called the 2012 DOE standard working condition, and the latest 2019 DOE standard working condition is 65℉/60%RH. The dehumidification capacity of the dehumidifier under these three working conditions is generally expressed as the maximum dehumidification capacity under the saturated working condition, because the temperature and humidity in the saturated working condition are higher than the other two. At present, the AHAM (80°F/60%RH) is more recognized on the market, so it is often marked in the label and manual.
Dehumidifier body size
In addition to the dehumidification capacity of the dehumidifier, we also need to consider the physical size of the dehumidifier. Because some growing room dehumidifiers are more complicated, heavier, and take up more space. Some small growing room dehumidifiers (portable dehumidifiers) can be placed in the growing room even in a small space.
Taking into account the space usage of the growing room, the dehumidifier also has a cabinet-type portable dehumidifier and a overhead ceiling dehumidifier.
Generally, people tend to use the first model in a growing room with sufficient floor space because it is more cost-effective. However, the second type is more suitable for growing rooms that need to make full use of the ground space and plant some high-value plants, and people have a relatively high acceptance of the price. You can choose to purchase the corresponding type of dehumidifier according to the actual application scenario requirements, and optimize the cost as much as possible on the premise of ensuring the normal growth of plants.(to be continued)
