Systeme für Abluft in Growboxen
What Should Be an Essential Part of Your Grow Box? An Exhaust System.
Plants convert carbon dioxide into oxygen. However, within your indoor grow room, the available CO₂ will eventually be depleted, and your plant will urgently need a fresh supply. What’s the solution? A fan that removes stale air so fresh air can flow in. At Cannvisa, you’ll find everything you need to efficiently guide the exhaust air from your grow box outside.
Removing Exhaust Air from the Grow Box
Besides the fact that your cannabis plants need CO₂-rich air to breathe, a well-designed exhaust system for your grow box provides additional, indispensable benefits. So, if you’re thinking, “I’ll just leave the grow tent door open,” we strongly advise against it. Air exchange is just one reason why proper ventilation is crucial for growing.
Odor Control
Pop open a stash jar and take a deep breath: bliss. The unique aroma, which people either love or hate, doesn’t just develop during the drying process. Your plant will start emitting its characteristic cannabis scent quite early, and during the flowering phase, the smell becomes so intense that hiding your hobby will no longer be an option.
Pest Control
Fungus gnats have never been anyone’s best friends. And yet, they aren’t the worst thing that could plague your cannabis plant, as they’re at least manageable. Thrips? Nearly impossible to eliminate. Spider mites? They can kill your plants. And battling aphid infestations indoors? Spare yourself the stress by equipping your grow box with an exhaust system.
Humidity Management
Life on Earth depends on water – and where there’s life, there’s moisture. Cannabis plants both produce and consume water, sometimes even excessively. Without regulation, humidity levels in your grow box can become too high, especially after watering, increasing the risk of mold growth.
Adding an exhaust system to your grow box is a no-brainer. Not only does it provide your plant with the necessary CO₂, but it also gives you much better control over other environmental factors – as long as you keep the grow tent door closed.
What Types of Exhaust Systems Are Available for Grow Boxes?
Cannvisa offers a range of options to suit different needs. Our compact mini-fans are ideal for smaller grow boxes and are incredibly easy to install. For larger setups, we have mixed inline duct fans that require more space and should be installed outside the tent. These fans are robust, efficient, and come with two speed settings. While your plants are still in their early growth stages, you can save electricity by running the fan at a lower setting.
What to Consider when Buying an Exhaust Fan for Your Grow Box
Installing an exhaust system isn’t rocket science, but there are a few key factors to consider before clicking “order”:
- Know the size of your grow box in cubic meters (m³) and review the technical specifications of the exhaust fan you’re considering. If the system isn’t powerful enough to exchange the air in your grow box quickly, it will weaken your plant. Ideally, the air should be completely exchanged every 1–3 minutes.
- Account for a carbon filter during the flowering phase. You can either DIY a filter using the right material or install a purpose-built carbon filter. Keep in mind that adding a filter will reduce the fan’s performance.
Here’s how to calculate the best exhaust system for your grow box:
- Determine the volume of your grow box (length × width × height).
- Check the fan’s capacity in the product description (e.g., 137 m³/h for a mini-fan).
- Divide the fan’s capacity by your grow box’s volume.
If the fan can fully exchange the air within one minute, it’s ideal. If it takes closer to three minutes or more, consider a fan with 20–30% more capacity to account for the future addition of a carbon filter.
Good to know: You usually don’t need to worry about intake air. Most grow boxes come with adjustable openings. Simply leave a small corner open, and the negative pressure will naturally draw in fresh air.
