Why a tube fan in your grow room?

✔ Ensures constant extraction of warm, moist or contaminated air
✔ Keeps temperature and humidity stable
✔ Prevents CO₂ deficiencies and mould growth
✔ Essential for odour control in combination with carbon filters
✔ Lowers the risk of heat stress and plant diseases

Whether you grow with a LED grow light or a heat-producing HPS lamp, a good extractor with tube fan provides balance and stability in your climate.

How do you determine the right extraction capacity?

The required capacity of a tube fan is expressed in m³ per hour (cubic metres of airflow per hour). A handy guideline is:

Room volume (m³) x 60 = hourly extraction capacity required
Additional factors such as lamps, filter resistance and heat production often require additional margin.

Guideline per lamp type:

• ✅ LED grow lights: add +20% additional extraction due to less heat

• ✅ HPS lamps: add +50% due to high heat output

• ✅ With carbon filter: calculate +25% extra due to back pressure

💡 Sample calculation (120x120x200 cm tent with 1x 600W HPS):

• Room volume = 1.2 x 1.2 x 2 = 2.88 m³

• Basic requirement = 2.88 x 60 = 172.8 m³

• +50% HPS = ~260 m³

• +25% filter = ±325 m³
  ➡ Recommendation: duct fan with ≥350 m³/h capacity

Always use a fan controller to automatically adjust the fan speed to the temperature in your tent.

Importance of a carbon filter

A tube fan alone is not enough for odour control - you need a carbon filter required that connects to the inlet of the extractor. The filter sucks the odour out of the air before it is exhausted through the fan.

At GrowDeal.nl, all our tube fans are can be perfectly combined with matching carbon filters, matched to diameter and air capacity.

Frequently asked questions about tube fans

Can I connect my tube fan directly to the carbon filter?
Yes, just make sure that both diameter and air capacity are well matched.

Does a tube fan make a lot of noise?
It depends on capacity and housing. Can Fan and Centro fans are relatively quiet, especially when combined with a fan controller or muffler.

Is a fan with more m³ always better?
No, too much extraction can lead to negative pressure and excessive drying out of your plants. Use a fan with controller for optimal balance.

How do I know if my fan is strong enough?
Use the calculation tool above or ask our team for personal advice.
