Grow Tent Kit 120 (Pure Factory)

Grow Tent Kit 120 from Pure Factory — Your Complete Indoor Grow Room

The Grow Tent Kit 120 from Pure Factory is a complete indoor growing system that gives you a 120 x 120 x 200 cm tent, a 320W LED grow light, ventilation, carbon filtration, and climate monitoring — everything assembled into one box. No hunting for compatible parts, no guessing whether your fan fits your ducting. You order it, set it up in under an hour, and you're growing. We've sold a lot of grow tent kits over the years, and this 120 x 120 size is the one we'd point you toward if you're running multiple plants and want proper harvests, not just a hobby corner.

What's Included in the Grow Tent Kit 120

Every component in this kit is matched to work together — the ducting fits the fans, the fans fit the tent ports, and the carbon filter handles the airflow volume. Here's the full breakdown of what arrives when you open the box:

That's 7 components, zero compatibility headaches. The reflective interior walls bounce light back onto your canopy instead of absorbing it, and the 125 mm fan ports are sized to match the included fans and ducting — no adapters, no tape bodges.

Why the 120 x 120 Grow Tent Kit Is the Best Size for Serious Indoor Growers

The 120 x 120 cm footprint gives you 1.44 m² of growing space — enough for 4 to 9 plants depending on your pot size and training method. That's a meaningful harvest, not a token effort. If you've been growing in a 60 x 60 or 80 x 80 and felt cramped, this is the jump that actually changes things.

At 200 cm tall, you've got headroom for the LED, the carbon filter hanging inside, and still enough vertical space for plants that stretch during flowering. The PureLED Q320 pulls 320W and covers the full 1.44 m² canopy evenly — that's roughly 222W per square metre, which sits right in the sweet spot for LED growing. Underpowered lights are the number one reason we see growers disappointed with their yield. This one won't leave you short.

The honest limitation? This kit takes up real space. You need a room, garage, or large cupboard that can accommodate 120 x 120 cm on the floor plus a bit of clearance around the sides for airflow and access. If your space is tight, the 80 x 80 kits are a better fit. But if you've got the room, the 120 x 120 produces harvests that actually make the electricity bill worthwhile.

The PureLED Q320 Grow Light — 320W of Proper LED Power

The Luminaria PureLED Q320 is the centrepiece of this kit. At 320W, it draws significantly less power than a comparable 600W HPS setup while delivering light across the spectrum your plants need for both vegetative growth and flowering. You'll notice the difference on your energy bill — and your plants won't notice any downside.

LED grow lights run cooler than HPS, which means less heat buildup inside the tent. That matters in a 120 x 120 space where temperatures can climb fast, especially in summer. The two 125 mm inline fans handle the rest — one pushes fresh air in, the other pulls warm, stale air out through the carbon filter. The result: consistent airflow, stable temperatures, and no telltale smells escaping into the rest of your house.

Ventilation and Odour Control — Carbon Filter Rated at 500 m³

The Carbon Pure Filter 125/300 is rated to process 500 m³ of air. For context, the internal volume of a 120 x 120 x 200 cm tent is 2.88 m³. That means the filter can cycle the entire tent volume roughly 170 times per hour — far more than you need, which keeps the filter working well within its capacity and extends its lifespan.

The 3 metres of 127 mm Alu+ ducting connects the extraction fan to the carbon filter and routes exhaust air out of the tent. The ducting is extra-durable aluminium — it holds its shape when you bend it and doesn't collapse under negative pressure like cheap plastic alternatives. We've seen growers duct-tape flimsy ducting back together mid-grow. This stuff doesn't need that.

The dual-fan setup (one inline, one TT model) creates proper negative pressure inside the tent. That means air only exits through the carbon filter, not through zip seams or port openings. Your neighbours, flatmates, and anyone walking past your door won't smell a thing.

Climate Monitoring — Temperature and Humidity at a Glance

The included Pure Factory Thermometer-Hygrometer tracks both temperature and relative humidity inside your tent. These are the two numbers that determine whether your plants thrive or struggle. Ideal ranges shift depending on growth stage — seedlings want higher humidity (around 65-70% RH), while flowering plants prefer it drier (40-50% RH). Temperature sweet spot sits between 20-28°C for most species.

Having the monitor inside the tent from day one means you can spot problems before they become disasters. A sudden humidity spike to 80%+ during flowering is how you get mould. A temperature drop below 15°C slows growth to a crawl. The analog timer automates your light cycle (18/6 for veg, 12/12 for flower), so the only daily check you need is a glance at the thermometer-hygrometer.

How to Set Up Your Grow Tent Kit 120

1. Unpack all components and lay them out. Check the contents against the list above — 7 items total.
2. Assemble the tent frame by slotting the metal poles together. The 120 x 120 x 200 cm frame goes up in about 10-15 minutes without tools.
3. Pull the tent fabric over the frame and zip it closed. Make sure the reflective interior faces inward and the fan ports are accessible.
4. Hang the PureLED Q320 grow light from the top crossbars using the included hangers. Position it centrally for even light distribution across the 1.44 m² canopy.
5. Mount the Carbon Pure Filter inside the tent near the top (heat and smells rise). Connect one 125 mm fan to the filter using the Alu+ ducting, and route the ducting out through a fan port.
6. Position the second 125 mm fan at a lower port to push fresh air into the tent. This creates the negative pressure that keeps odours contained.
7. Plug the grow light into the Pure Factory Analog Timer. Set your light schedule — 18 hours on / 6 hours off for vegetative growth, 12/12 for flowering.
8. Place the thermometer-hygrometer at canopy height inside the tent. This gives you the most accurate reading of what your plants actually experience.
9. Add your pots, growing medium, and plants. Close the tent, switch everything on, and you're running.

From Our Counter — What We've Learned Selling Grow Tent Kits Since 1999

The single biggest mistake we see with indoor growing? Buying components separately without checking compatibility. A 150 mm fan doesn't fit a 125 mm port. A 200W LED doesn't cover 1.44 m². A cheap carbon filter rated at 200 m³ gets overwhelmed in a tent this size and starts letting smells through within weeks. The Pure Factory kit solves all of this because every part is matched — the 125 mm fans fit the 125 mm ports, the 500 m³ filter handles the extraction volume with headroom to spare, and the 320W LED covers the full canopy.

The second mistake: skipping the thermometer-hygrometer. We get customers coming back frustrated because their plants look unhealthy, and it almost always traces back to temperature or humidity being off. You can't fix what you can't measure. Having the monitor included from the start means you're not guessing — you're growing with data.

Compared to the smaller 80 x 80 grow tent kits, the 120 x 120 gives you roughly double the floor space (1.44 m² vs 0.64 m²). That's the difference between 2-3 plants and 4-9 plants per cycle. If you're growing year-round and want harvests that stack up, the 120 is where the maths starts working in your favour. If space is genuinely limited, the 80 x 80 still does the job — but you'll outgrow it faster than you think.
