Maintaining Growroom Yields During Drought: Part II
Regardless of Drought
Dehumidifiers are essential to healthy yields, because they help maintain optimal moisture levels in grow rooms. They can also solve the drought-induced water scarcity so many growers face: Dehumidifiers can provide you with a source of clean, readily accessible water even during drought.
Dehumidifiers can Give you a “Free” Renewable Supply of Water
A dehumidifier is basically a refrigeration system. It has two copper tubing coils; each coil looks similar to an automotive radiator. One of the coils is hot, and the other is cold.
The system works by pulling heat from the cold coil and “exhausting” it through the hot coil. A fan blows air through the system, which removes water from the air and heat from the hot coil. The water condensate forms on the cold coil, like condensate will form on a glass of ice water during a hot day.
The condensate then runs off the cold coil and is collected into a reservoir.
Dehumidifier Water can be Preferable to Reverse-Osmosis Filtered Water, thanks to the “Multiplier Effect”
Even without a drought, it’s preferable to use the perfectly good water that dehumidifiers produce rather than “dump” it – and it can actually be better than reverse osmosis water. Why? Condensate water from dehumidifiers is naturally clean and free of contaminants, while reverse osmosis machines must necessarily waste 1 to 3 gallons of water to produce a single gallon of clean water. Every gallon of dehumidifier condensate saves 2-4 gallons of water drawn out of the tap.
Is the Condensate Water Clean and Free of Contaminants?
Yes. The cold condensate coil is enclosed within the dehumidifier. Because dehumidifier coils are not soldered with lead as is common in other applications, there’s no chance of lead contamination, either. Instead, copper coils are brazed.
