Military-Grade Dehumidifiers that Help to Maintain a Perfect Environment, Accelerating Growth Rates and Eliminating Mildew and Rot

If your plants are suffering from high humidity levels, then running a Quest Dehumidifier is the answer to your problems. High humidity can destroy entire crops by slowing down growth rates and encouraging mould and mildew. Quest dehumidifiers solve this issue by sucking enormous volumes of water from the air reliably and effectively, whenever they're needed. They're built to specifications that make them a favourite across numerous industries and government organisations, including the military. Quest dehumidifiers are even trusted for use onboard naval destroyers! Buy one of these pieces of kit and rest assured that you've chosen wisely.

How the Quest CDG 114 Works:

Getting your environmental parameters within optimal ranges is the key to successful growing. Relative humidity plays a huge role in dictating the growth rates of your plants. When humidity levels are too low, the rate of transpiration increases, causing the plant to lose too much water. Likewise, when humidity levels are too high, growth rates slow down dramatically, and the door is also opened up to an array of moisture-related issues, like powdery mildew and botrytis (rot). As plants reach their later stages, they can put a lot of water vapour into the surrounding atmosphere. Much of this vapour will leave the room via your extraction system, but if humidity levels in the room are still too high, then you're going to need some extra help...

The Quest CDG 114 is capable of removing water from the air at a rate of 55 litres per day. It comes with built-in wheels making it easy to transport, should you want to move it to a different room. 

Quest dehumidifiers are quality products that are built to last. But don't just take our word for it... Take note of the fact that they are used in some of the most testing situations out there: on naval vessels, in laboratories, at swimming pools, and even breweries.

How to Use the Quest CDG 114:

Which size dehumidifier do I need? A good rule of thumb is to make sure that your dehumidifier is able to remove enough water to account for the water that you give to your plants. If you're giving them 50 litres per day, then make sure that your dehumidifier is able to cope with that volume of water.

Set-up for this unit is quick and easy. All you need to do is plug it into a wall socket. Quest dehumidifiers come with power cables fitted with 3-pin plugs, so you're good to go.

The CDG 114 comes with a length of pipe and a connector which needs to be attached to water outlet point located at the side of the unit. Just put the other end of the pipe wherever you want to send the water, whether it be to your tank or down the drain.

The CDG 114 doesn't come with a humidistat, so to get the best out of it, we recommend pairing it up with a separate controller unit that will switch the unit on whenever it's required, according to the conditions in your room. High-end controllers like the Dimlux Maxi Controller and the G.A.S. Enviro Controller are perfect for the job. Both systems are able to detect moisture levels in the air via humidity sensors. If moisture levels go above your ideal daytime or night-time setting then they'll switch on dehumidifying equipment as needed. Don't forget that, if you do decide to use it with a Maxi Controller, you'll also need the separately available humidity probe and Aux Box unit.
