The Zamnesia Grow Tent Kit 120x120x200 is the largest complete indoor grow kit in our growshop range — a 120×120×200 cm tent paired with a Phytonaut 480 W LED, 150 mm inline fan, 150 mm carbon filter and full climate control gear, ready for 3–5 plants and advanced training. This is the kit we'd set up if we had a spare room and wanted to stop messing about with half-measures.
What's in the Zamnesia Grow Tent Kit 120x120x200
This is the complete 1.44 m² indoor grow setup — tent, light, ventilation, climate control and all the small bits that usually catch you out on a Sunday night when the shops are shut. Total power draw sits in the 400–499 W range, which is exactly where you want a square-metre canopy.

Why the 120x120x200 is the kit to pick for advanced training
If you're planning ScrOG, mainlining, or running 3–5 plants with serious lateral branching, you need the floor space. A 1.2 m × 1.2 m footprint gives every plant roughly 0.3–0.4 m² of canopy — enough to spread out properly instead of fighting for light. The 200 cm height is the other half of the equation: once you've added the LED, ducting and pots, you've still got headroom for plants to actually stretch.
The Phytonaut 480 W LED is the engine here. At 480 W over 1.44 m², you're sitting around 330 W/m² — strong enough for flowering across the full footprint without scorching the canopy. Pair that with the 150 mm inline fan pulling air through the 150 mm carbon filter, and your tent stays at working temperature and your hallway stays odourless. The 152 mm clip fan handles intra-canopy airflow, which is the bit most beginners skip and most experienced growers swear by.
How the Zamnesia Grow Tent Kit 120x120x200 compares to smaller kits
The 120 sits at the top of the Zamnesia kit range. Here's how it stacks up against its closest sibling, the 100x100x200 kit:
| Spec | Kit 100x100x200 | Kit 120x120x200 |
|---|---|---|
| Footprint | 1.0 m² | 1.44 m² |
| LED | Phytonaut (lower wattage) | Phytonaut 480 W |
| Inline fan | 125–150 mm | 150 mm |
| Plants | 2–4 | 3–5 |
| Best for | Standard indoor grow | Advanced training, bigger yields |
If you've got the room and you're past your first or second grow, the 120 is the upgrade that actually pays off. If you're a first-timer in a small flat, the 80x80 or 100x100 kit is a saner starting point.

Complete your setup with quality soil or coco substrate, 11–18 L fabric pots (5 of them for a full canopy), pH and EC meters, and a base nutrient line. A small humidifier is worth its weight during the seedling stage — the 120 is a big volume to keep at 60–70% RH without help.
Why you need a kit this size for serious indoor growing
They start with an 80x80, train three plants properly, and within two grows they're sawing branches off because the canopy hit the LED. Then they buy a 120 anyway, and the 80 ends up in storage.
The other failure mode is buying a tent without proper ventilation. A 150 mm inline fan paired with a 150 mm carbon filter is the minimum for a 1.44 m² space — anything smaller and you're fighting heat, humidity and smell all at once. This kit ships with both, sized correctly, so you skip the "why is my tent 32°C" panic.
One honest limitation: this kit doesn't include pots, substrate or nutrients. Budget for those separately.
How to set up the Zamnesia Grow Tent Kit 120x120x200
- Assemble the steel frame on the floor — corner connectors slot together by hand, no tools needed. Takes about 20 minutes for a 120x120.
- Pull the tent fabric over the frame and zip it shut. Check all light leaks now, not after you've loaded it.
- Hang the Phytonaut 480 W LED from the top crossbar using the rope ratchet hangers. Start it 50–60 cm above where the canopy will sit.
- Mount the 150 mm carbon filter inside the tent at the top corner, connect the 150 mm inline fan to the filter outlet, and run the 2 m ducting through the top exhaust port.
- Clip the 152 mm clip fan to a frame bar, angled to move air across (not directly at) the canopy.
- Plug the LED into the 24h timer, set your light schedule (18/6 for veg, 12/12 for flower), and route the fan through the Grow Environment Controller.
- Tidy every cable with the velcro loop ties before you bring plants in. Future-you will thank present-you.
- Run the tent empty for 24 hours and check temperature and humidity sit in range (22–26°C, 50–65% RH) before introducing plants.
Frequently Asked Questions
How many plants fit in the Zamnesia Grow Tent Kit 120x120x200?
Three to five plants is the sweet spot. Three large plants with advanced training (ScrOG, mainlining) will fill the 1.44 m² canopy beautifully. Five smaller plants in 11 L pots also works for a more traditional indoor grow.
Is the 480 W Phytonaut LED strong enough for a 120x120 footprint?
Yes. At 480 W over 1.44 m² you're hitting roughly 330 W/m² — solid flowering intensity for the full canopy. Hang it 40–60 cm above the canopy during flower and adjust based on plant response.
Does the kit include everything for ventilation and odour control?
Yes — 150 mm inline fan, 150 mm carbon filter, 2 m of 150 mm flexible ducting, and a 152 mm clip fan for intra-canopy airflow. The carbon filter handles smell completely when sized correctly to the fan, as it is here.
What's not included in the kit?
Pots, substrate (soil or coco), nutrients, pH/EC meters, and seeds or clones. The kit covers the tent, light, ventilation, climate control and hanging hardware — the cultivation consumables you buy separately based on your growing style.
Can a beginner use the Zamnesia Grow Tent Kit 120x120x200?
You can, but it's built for growers ready to do advanced training and run 3–5 plants. If it's your first indoor grow, the 80x80 or 100x100 kit is easier to dial in. If you've done one or two grows already, the 120 is the upgrade that genuinely pays off.
How long does the Zamnesia Grow Tent Kit 120x120x200 take to set up?
Around 60–90 minutes from box to ready-to-plant. Frame assembly takes 20 minutes, fabric and ducting another 30, and cable management plus a 24-hour empty test run finishes the job.
