Grow Room Environment Control

Grow Room Environment Control is the key to unlocking healthy, high-yield plants. Lighting and nutrients only get you so far—without stable temperature, humidity, and airflow, plants can struggle to reach their potential. This collection brings together everything you need to create the perfect climate for your grow tent or grow room.

• Air Circulation: Keep fresh air moving with oscillating fans and circulation kits.
• Carbon Filters & Odour Control: Neutralise smells with activated carbon filters and inline odour solutions.
• CO₂ Enrichment: Boost photosynthesis with CO₂ bags, tanks, and regulators.
• Ducting & Extraction: Connect your system with ducting and extraction kits.
• Fan Speed Controllers: Fine-tune your setup with adjustable fan controllers.
• Full Climate Control: Advanced air-con and climate systems for total environment mastery.
• Heaters & Humidifiers: Maintain ideal VPD with heaters and humidifiers/dehumidifiers.
• Intake & Filtration: Freshen incoming air with intake/outtake fans and intake filters.
• Ozone Generators & Silencers: Add ozone generators for odour control and silencers for quieter airflow.

Why Grow Room Environment Matters

Your grow room climate affects everything—plant health, growth speed, nutrient uptake, and yields. Too hot, and plants wilt. Too cold, and growth slows. Without enough airflow, you risk mould, mildew, and pests. Controlling your environment means giving your plants the perfect conditions to thrive.

Grow Room Environment FAQs

What’s the ideal temperature for a grow room?
Most plants thrive between 22–28°C during the day, with a slight drop at night. LEDs usually run cooler than HPS, so adjust accordingly.

What’s the right humidity for plants?
It depends on the stage. Young plants like 60–70% RH, while flowering plants prefer 40–50% to avoid mould. Use humidifiers or dehumidifiers to keep levels steady.

Do I need CO₂ enrichment?
If your environment is already dialled in and you’re running powerful lights, CO₂ can significantly boost yields. But only once temperature, humidity, and airflow are stable.

How do I reduce noise from fans?
Use acoustic ducting (check out Phonic Trap - the rolls royce of ducting!) and silencers to cut down sound while keeping airflow strong.
