How to Set Up a Grow Tent

Grow tents in the UK are extremely popular options to grow plants in. There are a few main supplies you’ll need to set up your grow tent, such as ventilation, lights, carbon filter, and ducting.


Benefits of Grow Tents

  • A perpetual harvest. If you want to grow more than one crop or different crops, grow tents are ideal. You can have separate vegetative and flowering grow tents to ensure a perpetual harvest. Easily manage the self-enclosed environments that grow tents provide. 

  • Inexpensive solution. Grow tents can be purchased from inexpensive prices such as £40, providing you with an inexpensive space with everything you need (air-tight vents, reflective walls, light proof, and much more). 

  • Reduces the risk of pests. Air can pass through the intake holes but most insects can’t. Almost all grow tents have the intake holes covered with mesh, which helps to keep spiders and other insects out.

  • Simple and easy to use. You can assemble a grow tent by yourself without the need for tools. It only takes around an afternoon for everything to be set up, equipment and plants included.


How to Set Up a Grow Tent

  1. Clean up the space in which you want to set up your grow tent in and put it together.

  2. Hand the grow lights; you can use rope ratchets, which will allow you to easily adjust your lights without fear of them falling.

  3. Hang up the exhaust fan inside your tent for efficiency. It will muffle the sound the fan makes and create a straight path for great airflow and circulation, from the lights to the fan.

  4. Connect the carbon filter to remove smells from your grow tent. You can hang it up with rope ratchets, ensuring there’s an air-tight line connecting it to the fan.

  5. Do a safety check. Make sure there are no electrical wires anywhere near water or in reach for them to be a trip hazard. Keep all electric devices above waist level and secure them.


Setting Up the Carbon Filter

Are you using an air-cooled HID light in your grow tent? For this set up, you’ll need to place the carbon filter before you place the reflector hood. There are two different ways you can set up this layout:


Filter - Ducting - Reflector Hood - Ducting - Fan 


Or


Filter - Fan - Ducting - Reflector Hood - Ducting


With an air-cooled HID light such as LED, HID, or CFL, it’s best to connect your carbon filter to the exhaust fan intake inside the grow tent. This will suck air straight through the filter and expel it outside the tent.

Simply make sure to get a grow tent bigger than your plants need so you can properly ventilate it, check your plants, and make other adjustments.


Setting Up Grow Lights

Grow lights should be placed as close as they can be to your plants, however, you need to be careful so they don’t burn or bleach them. The way to know if your lights are too close to your plants will depend on:

  • The coverage area

  • If they are LED grow lights, CFL, or HID

  • How many watts the lights have

  • What brand and model LED lights are

  • How effective the heat venting is with HID

When setting up grow lights, you need to make sure that the full area is covered. The lights need to not only cover the area where you have your plants, but they also need to penetrate the entire canopy - which includes the lower parts of the plants. 

With LED grow lights, it’s important to know the exact model and brand so you can adjust the distance from your plants. Different manufacturers will use different strength diodes and/or reflective lenses. Germination/seedling, vegetative growth, and flowering growth stages all have optimal distances.


For HID lights, you’ll need to know the watts and take into consideration the effectiveness and strength of the heat venting you’re using. If the light is too hot on the back of your hand, it will be too hot for your plants. There’s a general guideline based on watts and distances:

  • 40-60 cm or 16-24 inches: 400W (covers an area of around 8-12 sq ft)

  • 60-80cm or 24-31 inches: 600W (covers an area of around 12-16 sq ft)

  • 80-100cm or 31-39 inches: 1,000W (covers an area of around 16-20 sq ft)
