Great Stuff Hydroponics provides industry-leading climate solutions designed for growers of all levels. Our Grow Room Ventilation Kits take the guesswork out of environment control by pairing high-pressure extractor fans with premium carbon filters and durable ducting. Whether you are managing heat from HID lighting or scrubbing odours, our curated kits ensure optimal airflow and plant health for a successful harvest every time.

FAQ's

  • What is included in a grow room ventilation kit?

    A standard ventilation kit includes an extractor fan to move air, a carbon filter to remove odours, and a length of flexible ducting with clips to connect the system. These kits are designed to create "negative pressure," ensuring all air exiting the grow space passes through the filter.

  • How do I choose the right size ventilation kit for my grow tent?

    To calculate the required airflow, multiply the volume of your grow space (Length x Width x Height) by 60 (to exchange air once per minute). This gives you the CFM or m3/h requirement. Ensure your extractor fan rating meets or slightly exceeds this number to account for the resistance caused by the carbon filter.

    See our blog post: Grow Room Ventilation: How To Calculate Airflow Like A Pro for a more in-depth guide.

  • Why do I need a carbon filter in my ventilation setup?

    Carbon filters are essential for odour control. They use activated charcoal to trap organic compounds (smells) before the air is exhausted outside. For maximum efficiency, we recommend the Rhino Pro the or CarboAir carbon filters for long-lasting performance.

  • Should I run my ventilation kit 24 hours a day?

    Yes. Plants need a constant supply of CO2 during light hours, and they continue to respire and produce moisture during the dark cycle. Constant ventilation prevents stale air, reduces the risk of mould/botrytis, and ensures odours are always being neutralised by the carbon filter.

  • What is the difference between an AC fan and an EC fan kit?

    Traditional AC fans are affordable but can be noisy when dimmed. Modern EC (Electronically Commutated) fans are significantly more energy-efficient and can be precisely controlled without humming. Check out our EC Fan Kits if you are looking for silent, high-torque performance.

  • Where should I position my fan and filter?

    For the best results, hang your carbon filter and fan as high as possible inside the grow tent, as heat rises. The air should be sucked through the filter, passed through the fan, and exhausted out of the room. Use acoustic ducting to further reduce the noise of the air movement.
