Grow Room Setup 101

When setting up a grow room, there are a few basic factors to take into consideration. The space, the lighting, and the airflow need to be prioritised to ensure your plants have the best possible environment to grow healthy and strong.


Basic Safety in the Grow Room

  • Install a fire extinguisher designed specifically for grow rooms.

  • Make sure that electrical devices and lights don’t come in contact with water.

  • Keep all wiring tidy and out of the way to avoid tripping hazards.

  • Always read product instructions and safety precautions carefully.

  • Ensure reflector cables aren’t coiled up and uncoil extensions, as otherwise they can get hot and cause a fire.


The Perfect Space

Even a small room can easily be transformed into a grow room. You can convert an entire room in your home or use a grow tent. Make sure that the space you choose has the basic necessities, such as a power and a water supply. If you only need to use one or two lights in your setup, double wall sockets should do the trick.

Never use unfiltered rainwater for hydroponics, as you could be seriously hurting your plants. The best water you could provide your plants is pure and filtered water. You can then safely provide balanced nutrients to your plants.

You should also make sure that you don’t set up your grow room on carpeted floors. Carpets will hold any moisture or spillage and grow bacteria and other pathogens and bugs. Take into account how noisy pumps, lights, and fans can be when choosing the perfect space.

The Ideal Lighting

Grow rooms need a light-tight environment. This means that, if there is a natural light source in your space, you need to make sure that it’s blocked off or that you light trap the space. You can use reflective sheeting to stop light from escaping and to keep natural light out of your grow room.

Controlling light in your grow room prevents plants from being exposed to light at inconsistent intervals, which makes them being confused and stressed.  You’ll need a main and a supplement light for the best results. Grow lights are composed of:

  • Ballasts. Regulate and control the energy supply that powers the light.

  • Reflectors. Guide the light produced down towards the plants.

  • Lamps. Generate the light needed for your plants.

Many growers utilise a Dual Spectrum HPS (High Pressure Sodium) light during the entire growth cycle. In addition to HPS lights, there are a few main grow lights you can choose from, which tend to emit within the wavelengths that plants need (400nm-700nm):

  • Sodium. Produces more red light, making it ideal for flowering.

  • Dual Spectrum HPS. Produces blue and red light, which is ideal for both vegetative and flowering growth.

  • Fluorescent Lights. Ideal for propagation.

  • Metal Halide. Produces more blue light, making it ideal for vegetative growth.

  • LEDs. Can be used throughout the entire grow cycle.


The Ideal Airflow System

Perhaps the easiest way of controlling your grow room’s climate, a proper airflow system is essential. Plants consume CO2 and release moisture, alongside lights producing heat - which affect your grow room’s climate.

You’ll need a great airflow system to balance the humidity, heat, time of year, size of the room, and amount of lights. Fan speed controllers speed up or slow down according to the grow room needs and depending on the temperature, ensuring that you provide the ideal airflow.

Keep the location of your grow room in mind; south-facing rooms will be hotter than rooms facing other directions, which may lead to grow rooms needing a bigger extractor fan. If you’re unsure, a fan speed controller is sure to do the trick. Bigger grow rooms will also need an intake fan, which should be approximately 20% less powerful than the extractor fan. Place them in opposite corners for better results.
