Room first, equipment second
Build around a clear 3 x 3 ft footprint
The 36 x 36 in floor creates a defined indoor growing zone. Plan the front-door clearance, power route and exhaust direction before adding the light, fan and filter.
- 9 sq ft floor
- Front access
- Flexible vent routing
Listed U.S. size
36 x 36 x 70 in
Measure the room, ceiling clearance and service access before ordering equipment for the enclosure.
Why choose this enclosure
A practical shell for a custom indoor setup
The tent gives lighting, airflow and plant care a defined space. Its 600D Oxford exterior, reflective Mylar interior and steel support structure form the base. You decide which equipment completes the system.
- 600D
- Oxford exterior
- Mylar
- Reflective interior
- Steel
- Support frame
Lighting, fan, filter, ducting, controls, containers and plants are not included with the standalone enclosure.
Dense exterior and steel support
The 600D Oxford shell and steel frame create a purpose-built enclosure for an indoor equipment layout.
Vent access for a separate airflow plan
Multiple openings let you route compatible intake, exhaust and ducting around the fan and filter you select.
Quick checks and daily tool storage
The product media shows an observation window and exterior tool pocket for routine access around the tent.
Leave enough height for the complete equipment stack
The listed 70 in enclosure height must hold the plant, container, hanging hardware, light and the safe distance between the fixture and canopy. Filter and duct placement can reduce the usable height.
Confirm the final light distance, ventilation route and room ceiling clearance before assembly.
Choose the tent size that fits the room
Start with floor area and working height, then select lighting and airflow for the enclosure you choose.
Start with the enclosure or choose a complete kit
Buy the standalone tent when you already know the light and airflow you want. Choose a complete kit when the core equipment should arrive in one order.
Standalone enclosure
3x3 Grow Tent
Best when you want the enclosure first and will choose the lighting and airflow separately.
- 36 x 36 x 70 in listed size
- 600D shell and reflective Mylar
- Steel support frame and vent access
Complete system
3x3 Complete Grow Tent Kit with MA200 LED Grow Light
Best when you still need a matched enclosure, grow light and the primary ventilation components.
- 3 x 3 ft grow tent
- LED grow light
- Inline fan, carbon filter and ducting
What this product does not include
The listing is for the standalone enclosure. A grow light, fan, filter, ducting, controller, containers, growing media and plants must be purchased separately unless the final cart contains a complete kit.

Frequently asked questions
Practical answers for sizing, equipment planning and ordering the standalone enclosure.
What does the 3x3 grow tent listing include?
The current U.S. record describes the standalone tent enclosure with a 600D Oxford shell, reflective Mylar lining and steel support frame. Lighting and ventilation equipment are not included.
How much room should I measure before ordering?
The product title lists 36 x 36 x 70 in. Leave extra room for the front door, exhaust route, electrical access and routine maintenance outside the enclosure.
Which grow light should I use in a 3x3 tent?
Choose by measured canopy area, crop stage, hanging clearance, heat and the light manufacturer's coverage data. Do not choose by wattage alone.
Does the tent include a fan or carbon filter?
No. This product is the standalone enclosure. Select a compatible fan, filter and ducting route separately, or compare the complete kit.
Can I check plants without opening the main door?
The current product media shows an observation window for quick visual checks. Open the enclosure when the plants need direct care or closer inspection.
Is the tent easy to assemble?
The current U.S. product record states tool-free setup. Assemble the steel frame first, fit the shell carefully and confirm that every joint is seated before hanging equipment.
Where can I check current U.S. shipping and returns?
Review the current Shipping Policy and Refund Policy before ordering.

FAQ
This 4 inch inline fan carbon filter combo provides the core exhaust and odor-control hardware for compact 2x2 to 4x4 grow tents. The package combines a ten-speed inline fan, refillable activated-carbon filter, 10 feet of aluminum ducting, timer, thermo-hygrometer, clamps, straps, and seals.
Real ventilation performance depends on the whole air path. Tent volume, equipment heat, filter resistance, duct bends, intake area, and room temperature matter more than a fan’s free-air rating by itself.
What is included?
- 4-inch inline fan with ten manual speed settings
- 4-inch refillable activated-carbon filter
- 10-foot aluminum ducting
- Digital timer
- Thermo-hygrometer
- Installation clamps, straps, and seals
Check the current packing list before purchase. A staged product image may include surrounding tent equipment that is not part of this ventilation package.
How the fan and carbon filter work together
The inline fan creates airflow through the filter’s activated-carbon bed. Air then travels through the duct and exits the enclosure. For odor control, every joint should be tight and most exhaust air should pass through the filter instead of leaking around it.
A filter adds resistance. Expect less airflow than the fan produces without ducting or a filter attached, and inspect the carbon media as performance changes over time.
Choose the four-inch size by system load
This kit is positioned for 2x2 through 4x4 tents. The correct fit also depends on light wattage, ambient room temperature, humidity, and duct routing. A compact tent with a hot room or long duct can be harder to control than a larger tent in a cool room.
| Use a four-inch starting point when | Recheck sizing when |
|---|---|
| The enclosure and heat load are compact | The grow uses a high-output fixture |
| The duct route is short and direct | The route has several bends or long runs |
| The intake path is adequate | The room itself stays warm or humid |
Installation order
- Choose an upper exhaust position and a lower intake path.
- Secure the carbon filter and fan with their own supports.
- Connect ducting with the airflow direction aligned.
- Seal and clamp every connection.
- Keep the duct as straight as the room permits.
- Start at a moderate speed and observe tent pressure.
- Record light-on and light-off temperature and humidity.
Manual speed and optional smart control
The fan includes ten manual settings for direct adjustment. It is also designed for compatible smart-system control. Before connecting any controller, verify the current port, cable, firmware, and manual rather than assuming compatibility from the connector shape.
The TheOneGrow smart tent controller is the current system reference for coordinated environmental control.
Four-inch or six-inch ventilation?
The four-inch package prioritizes compact equipment and smaller enclosures. The 6-inch inline fan and carbon filter combo is the comparison for larger 5x5 to 8x4 layouts or a system with a greater airflow requirement.
Do not size up only because a larger number looks safer. Excessive exhaust can make a small tent difficult to balance, while undersizing can leave heat or humidity uncontrolled. Match the system to measured conditions.
Maintenance and operating checks
- Inspect clamps and ducting for leaks, looseness, or crushing.
- Keep the fan intake clear of fabric and loose material.
- Check the refillable filter media according to the current instructions.
- Compare current airflow and odor control with the clean-system baseline.
- Clean monitoring tools and confirm that readings remain plausible.

Frequently asked questions
Does this kit include a grow tent?
No. It is a ventilation package. Tent, grow light, circulation fans, plants, and growing supplies are separate.
Can the carbon filter be refilled?
The current product information describes a refillable activated-carbon filter. Follow the latest instructions for media type, handling, and replacement.
Will it remove all odor?
No ventilation product can guarantee that result in every room. Correct sealing, carbon condition, airflow, humidity, and maintenance all affect performance.
Is this the right fan for every 4x4 tent?
Not automatically. Calculate around the installed light, filter and duct resistance, intake, room climate, and target air exchange.
Build a short, sealed exhaust path
A matched four-inch package simplifies component selection, but installation determines how well it performs. Support each part, minimize resistance, seal the joints, and test the full enclosure before relying on it.
