Complete Grow Tent Setup Guide Australia
Complete Grow Tent Setup Guide Australia
A complete grow tent setup requires more than just a tent. To create a controlled, productive indoor growing environment for herbs, leafy greens, chillies, tomatoes, propagation or ornamental plants, you will typically need the following components working together:
- Grow tent — the enclosed, reflective structure that contains your environment
- Grow light — sized to match the tent's floor area and your plants' light requirements
- Inline exhaust fan — to extract hot, humid air and maintain negative pressure
- Carbon filter — where odour filtration is required, matched to the fan's diameter and airflow
- Ducting and clamps — to connect the fan and filter and route exhaust air out of the space
- Circulation fan — to move air across the canopy and strengthen stems
- Temperature and humidity monitor — positioned at canopy height for accurate readings
- Timer or environmental controller — to automate lighting schedules and fan speeds
- Pots or hydroponic system — suited to your chosen growing method
- Growing medium — soil, coco, rockwool, or a hydroponic substrate
- Nutrients — base and supplemental feeds matched to your medium and growth stage
- pH and EC testing equipment — to verify nutrient solution and growing medium conditions

Choose Your Grow Tent Size
Selecting the right tent size before purchasing any other component is the most important decision in planning your setup. Your tent's floor area determines which lights, fans and filters are appropriate. Measure your available space carefully, including ceiling height and room for access around the outside.

Note: Plant numbers are not stated in this guide. Only purchase a tent size you can adequately light and ventilate within your available space and electrical capacity.
Match the Grow Light to the Tent
Fixture wattage alone does not determine whether a light is suitable for your tent. When selecting a grow light, consider the following factors together:
- Fixture dimensions — a large bar-style fixture may not fit or hang correctly in a small tent
- Manufacturer-rated coverage area — use the flowering coverage figure, which is typically smaller than the vegetative coverage area
- PPFD distribution — photosynthetic photon flux density at canopy height; higher is not always better if it creates hot spots
- Efficiency (µmol/J) — higher efficiency means more light output per watt of electricity consumed
- Hanging height — affects coverage area and intensity; check the manufacturer's recommended hanging distance
- Dimming capability — allows you to reduce intensity during propagation or when plants are young
- Heat load — all lights produce heat; LED fixtures produce less than HPS but still contribute to tent temperature
- Canopy shape — bar-style fixtures distribute light differently to square panel fixtures

Size the Inline Fan and Carbon Filter
Calculate Your Tent Volume
Use this formula to calculate the internal air volume of your tent:
Tent volume (m³) = length (m) × width (m) × height (m)
Example: a 1.2 m × 1.2 m × 2.0 m tent has a volume of 2.88 m³.
As a general starting point, aim to exchange the full tent volume of air at least once per minute under load. In practice, your actual fan selection will need to account for additional resistance factors.
Factors That Affect Ventilation Requirements
- Tent volume — larger tents require higher airflow capacity
- Grow light heat output — higher-wattage fixtures add significant heat load
- Brisbane summer conditions — ambient temperatures in Brisbane can exceed 35°C, which increases the difficulty of maintaining target temperatures inside the tent
- Carbon filter resistance — filters restrict airflow; always factor this into fan selection
- Duct length — longer runs reduce effective airflow
- Duct bends — each 90° bend reduces airflow; minimise bends where possible
- Silencers and mufflers — add acoustic insulation but also add resistance
- Intake restrictions — blocked or undersized passive intakes reduce extraction efficiency
- Desired noise level — quieter fans and silenced housings are available if noise is a concern
Fan and Filter Sizing Reference — Based on Current Green Genius Stock
Airflow figures are not reproduced here as they vary by speed setting and installation conditions. Refer to individual product listings for rated m³/h or CFM specifications. Fan and filter diameters must match — do not mix sizes without an appropriate reducer.

Where Each Component Goes
Follow this installation order to avoid having to disassemble and restart:
- Assemble the tent frame and fabric — on a clean, flat surface before moving it into position.
- Install the hanging support bars — check the tent's rated load capacity before hanging equipment.
- Hang the carbon filter (if used) — typically suspended from the top cross-bar inside the tent, near the exhaust port.
- Install the inline fan — connect it directly to the carbon filter outlet using a clamp, or position it outside the tent connected via ducting.
- Connect the ducting — run from the fan outlet to the exhaust port and out of the space. Minimise bends and keep runs as short as practical. Seal all joins with aluminium tape or clamps.
- Hang the grow light — use the tent's hanging bars and appropriate ratchet hangers. Check the total weight against the tent's rated capacity.
- Install circulation fans — clip fans such as the AC Infinity Cloudray S6 or Cloudray S9 can be attached to the tent frame to move air across the canopy.
- Position environmental sensors at canopy height — do not place sensors directly in front of a fan or directly under the light.
- Route cables safely — use the tent's cable ports and keep power cables away from water sources and irrigation lines.
- Add pots, trays or the hydroponic system — ensure runoff trays are in place before adding growing medium or water.
- Test the complete setup before adding plants — run the lights, fans and any timers or controllers for at least 24 hours to confirm temperatures, humidity and equipment function correctly.

Managing Brisbane Heat and Humidity
Brisbane's subtropical climate presents specific challenges for indoor growers, particularly during summer when ambient temperatures regularly exceed 30–35°C. Understanding the limitations of ventilation is important before you invest in equipment.
- Heat from the surrounding room enters the tent — your inline fan draws air from the room into the tent through passive intakes. If the room is already hot, the air entering the tent will be hot.
- Exhaust air must not re-enter through the intake — route exhaust ducting away from the passive intake vents. Short-cycling extracted air back into the tent defeats the purpose of ventilation.
- Increase circulation during hot periods — additional clip fans help move air across the canopy and reduce localised heat build-up, but do not lower the overall temperature.
- Monitor both day and night conditions — temperatures inside the tent can drop significantly at night when lights are off, particularly in winter. Both extremes affect plant health.
- An inline fan cannot cool below the surrounding room temperature — extraction removes heat generated inside the tent, but it cannot refrigerate the incoming air. If your room is 35°C, your tent will be at least 35°C regardless of fan speed.
- Air conditioning or dehumidification may be necessary — in Brisbane summers, growers running high-wattage lights in enclosed spaces often find that ventilation alone is insufficient. Cooling the surrounding room or using a dedicated air conditioning unit is the most reliable solution for temperature control in hot conditions.
- Humidity management — Brisbane's humidity varies significantly by season. High humidity combined with poor airflow can create conditions that affect plant health. Monitor relative humidity at canopy height and adjust ventilation or use a dehumidifier if required.

Common Grow Tent Setup Mistakes
Avoiding these mistakes before you purchase will save time, money and frustration:
- Buying a light before choosing the tent — the tent size determines which light is appropriate, not the other way around. Start with the tent.
- Mismatching fan, filter and duct diameters — all three must share the same diameter. Reducers add resistance and are best avoided where possible.
- Too many duct bends — every bend reduces effective airflow. Plan your duct run before purchasing ducting and aim for the straightest path possible.
- Positioning sensors directly in front of a fan — airflow across a sensor gives artificially low temperature and humidity readings. Mount sensors at canopy height away from direct airflow.
- Blocking passive intakes — the tent needs to draw fresh air in through the lower vents. Blocking these forces the fan to work harder and reduces extraction efficiency.
- Ignoring total electrical load — add up the wattage of your light, fans, pumps and controllers. Ensure your circuit can handle the total load safely.
- Hanging too much weight from the tent frame — check the rated hanging capacity of your tent before suspending lights, filters and fans. Overloading the frame can cause structural failure.
- Failing to use runoff trays — water and nutrient solution will overflow without trays in place. This damages floors and creates hygiene issues.
- Building the setup before checking access and ceiling height — measure your ceiling height and confirm you have enough clearance for the tent, ducting and any overhead equipment before purchasing.
- Assuming ventilation can overcome a hot surrounding room — as noted above, extraction cannot cool below ambient room temperature. Plan your room environment before relying solely on tent ventilation.

Frequently Asked Questions
What equipment do I need for a grow tent?
A complete grow tent setup requires a tent, a grow light sized to the tent's floor area, an inline exhaust fan, a carbon filter (where odour filtration is needed), flexible ducting and clamps, a circulation fan, a temperature and humidity monitor, a timer or environmental controller, pots or a hydroponic system, growing medium, nutrients, and pH and EC testing equipment.
What grow tent size should a beginner choose?
A 100 × 100 cm or 120 × 120 cm tent is a practical starting point for most beginners. These sizes are large enough to grow herbs, chillies, tomatoes or leafy greens productively, while remaining manageable in terms of equipment cost and environmental control. Measure your available space carefully before purchasing.
What size light do I need for a 120 × 120 cm tent?
Based on products currently listed at Green Genius, the AC Infinity Ionframe EVO6 (500 W, rated for 120 × 120 cm flowering coverage), the LFG 600 W LED and the LFG 720 W LED (both rated for 120 × 120 cm to 150 × 150 cm) are suitable options. Always verify coverage specifications on the individual product listing before purchasing.
What size inline fan do I need?
Calculate your tent volume (length × width × height in metres) and select a fan capable of exchanging that volume at least once per minute, accounting for the resistance added by your carbon filter, ducting length and any bends. For a 120 × 120 × 200 cm tent (2.88 m³), a 150 mm fan is a common starting point. Refer to the sizing table above and individual product listings for rated airflow figures.
Does an inline fan need to match the carbon filter diameter?
Yes. The fan and carbon filter must share the same flange diameter to connect directly. Mismatched sizes require a reducer, which adds airflow resistance and potential leak points. Always purchase a fan and filter with matching diameters.
Should the fan go inside or outside the tent?
Either configuration can work. Placing the fan inside the tent (connected directly to the carbon filter) keeps noise inside the tent but adds heat. Placing the fan outside the tent (connected to the filter via ducting) moves heat out of the tent but may increase noise in the surrounding room. Both approaches are used by growers — choose based on your space and noise requirements.
How often should grow tent air be replaced?
A common guideline is to exchange the full tent volume of air at least once per minute under load. In practice, the appropriate exchange rate depends on your light's heat output, ambient room temperature, and the resistance in your duct system. Variable-speed fans and environmental controllers allow you to adjust airflow in response to actual temperature and humidity readings.
Do I need both an exhaust fan and a circulation fan?
Yes. The inline exhaust fan removes hot, humid air from the tent and maintains negative pressure. The circulation fan moves air across the canopy to reduce hot spots, strengthen stems and improve transpiration. They serve different functions and both are recommended for most setups.
Can a grow tent be used in a Brisbane garage?
Yes, but Brisbane garages can reach very high temperatures in summer, which will directly affect the temperature inside the tent. If your garage regularly exceeds 30–35°C during the day, ventilation alone is unlikely to maintain suitable growing conditions without additional cooling. Consider the ambient temperature of your space before purchasing equipment.
