Grow Room Environment Controllers

Set your grow room on autopilot by taking advantage of the ease of growing outside while keeping all the great benefits of indoor gardening. Environmental controllers are a great way to both monitor and control your grow room. It’s easy to feel tied to your indoor garden and makes scheduling more than a couple days away a nightmare. Controllers break that chain giving you a life outside your garden.

At Hydrobuilder, we offer a wide range of controllers, from simple and affordable controllers that will monitor and control one factor to multi-functional controllers that can control lights, CO2, temperatures, and humidity.

When choosing an environmental controller you’ll need to consider your budget, the degree of control, and how your grow room is set up. For example, a basic cycle timer with two outlets can act as a light controller and simple temperature controller, as it will turn your fan(s) off when your lights go off.

Take some time and look over our various top of the line controllers and see how they vary on the factors they control and to what degree. Many of our most popular controllers will have a diagram that shows you how different devices/setups plug in and work with the controller.

Speaking of plugging in, the heavy majority of our controllers easily plug right into a standard 120V house outlet.

Let’s looks at each way controlling these factors will score you brilliant high-quality yields at harvest:

Grow Room Light Schedules

If there is one environmental controller you purchase it should be a light timer, and most gardeners from small home grower to those running commercial operations will agree. The light schedule will determine what stage of life your plant will be in. Photoperiod plants in the flowering stage must have a 12/12 schedule - 12 hours lights on, 12 hours lights off - and if their dark period is interrupted or moved around it can spell disastrous results.

Light/cycle timers allow growers to easily set and customize their preferred light schedules. More advanced versions will even let you set your light schedule ahead of time making the switch from veg to bloom for you.

Grow Room Temperature & Temperature Controllers

If you don’t keep your temperatures within a comfortable range for your plants, you’ll put both yield and its quality in jeopardy. Grow lights create a lot of heat and a ventilation system is always advised. Ventilation systems have to be fairly powerful to remove all the built-up heat, but if left on when the lights are off you may drop your grow room to frigid temps.

Temperature controllers will turn your ventilation system on and off based on your temperature settings. More advanced units will let you set separate day and night temperatures which will replicate outdoor temperature fluctuations. A lower night time temperature creates a natural environment which plants respond well to leading to a better harvest.

Grow Room Humidity & Humidity Controllers

Humidity plays a big role in multiple factors for your plants from how fast they drink from their media to keeping mold off them when they are in flowering, and this just scratches the surface.

Humidity controllers work similar to temperature controllers but monitor the percentage of humidity in the grow room instead. Some allow you to connect multiple units such as humidifiers, dehumidifiers and exhaust fans. Smaller versions will only let you plug in one, but they are more affordable.

Grow Room CO2 & CO2 Controllers

Supplementing extra CO2 into your grow room/tent is a great way to boost plant growth and development. You can boost yields by 20-40%, so if you’re someone that wants the biggest and best plants, you’ll have to give your plants extra CO2.

CO2 controllers will monitor the CO2 levels in the grow room and turn CO2 generators on and off based the ppm (parts per million) settings of your choice.

Grow Room Ventilation & Ventilation Controllers

If you read about the importance of temperature and humidity controllers, you know ventilation is key so let’s jump straight to what these controllers can do for you.

Ventilation controllers can be simple like a fan speed controller that allows you to set your fan’s motor speed - while a simple mechanism it’s a big help when a new season and different outside temperatures roll around. They can also be more complex and monitor temperatures as you see above with the temperature controllers.

Monitoring Your Grow Rooms Environment

Most environmental controllers monitor your environmental factors for you, but unless you go with an all-in-one multi-functional controller, you’ll probably want a separate device that tells you tells you the temperature and humidity in the room.

Like a light timer, a device that tells you the temperature and humidity is essentially a requirement. It’s entirely possible to get lucky and grow without one, but having will make you a better grower and grow you better healthier plants.
