    Introduction of Guard70 Ceiling Mounted Dehumidifier

    The power supply of the Guard70 dehumidifier is 230V/50Hz, suitable for most countries in Europe, Southeast Asia, and South America. The working temperature range of the machine is 5-38℃, and the controllable humidity range is 30-80% RH. In an environment of 26.7 ℃/60% RH, the dehumidification capacity of the dehumidifier is 70L per day. At 32.2°C/90RH, the dehumidification capacity is 145L/D. At 15℃/60% RH, the capacity is 45L/D. At the beginning of the design, engineers specifically optimized the operation at low temperatures, adjusting the capillary tubes to ensure even cooling of the evaporator, making the machine suitable for the entire cultivation period of cannabis. Its drainage method is direct discharge without a water pump (recommended to install it on the ceiling or put it on an elevated platform). The body design is simple, with an air inlet on the front and an air outlet on the back. The dehumidifier is user-friendly, with clear error codes, interfaces, and warning labels on its body.

    Why Choose the Guard70 Grow Tent Dehumidifier

    Temperature and humidity are one of the most critical environmental factors in cannabis cultivation, which directly affect the growth rate, yield, and flower quality of plants. High temperature can cause plant growth to stagnate, flower buds to loosen, and THC content to decrease. Low temperature can lead to weakened root activity and insufficient nutrient absorption in plants. High humidity can result in frequent diseases and mold growth. Low humidity can bring high transpiration pressure and slow growth of plants. Overall, temperature affects the metabolism and synthesis of active ingredients in cannabis, while humidity affects water balance and disease incidence.

    The Guard70 dehumidifier has the following advantages, which can help growers control indoor humidity to a large extent.

    Designed for Indoor Plant Growth. Ceiling type, saving floor space.
