Your first grow tent setup decides how the next three months go. Get the layout right on day one and the tent looks after itself - get it wrong and you'll be chasing heat, humidity and smell the whole way through. The good news is the kit list is short and the order is simple. Here's everything that goes in, the order it goes in, and the gear we'd hand a first-time grower across the counter.
The full grow tent kit checklist
Before you hang a single thing, get the whole kit together. Buying it piecemeal is how people end up with a fan that doesn't match the filter or ducting that's three sizes off. The core list:
- The tent - your sealed, light-proof room
- An LED grow light - sized to the tent's footprint
- An inline (extraction) fan - pulls hot, used air out
- A carbon filter - scrubs smell on the way out
- Ducting + clamps - connects fan, filter and exit port
- Clip or oscillating fans - move air across the canopy
- Fabric pots - roots breathe, plants don't sit in wet feet
- A timer - runs your light cycle hands-free
- A thermo-hygrometer (and pH/EC meter) - so you're growing on numbers, not guesses
If you'd rather not piece it together, our grow tent kits and bundles come matched out of the box b tent, light, fan and filter sized to each other so nothing fights.
Step 1: Pick and pitch the tent
The tent is the room everything else lives in. We point most beginners at Secret Jardin tents - the Dark Room and Dark Street lines are tough, properly light-proof, and the poles actually take the weight of a filter and light without sagging.
Build the frame, check every zip runs clean, and leave the bottom intake vents open. Those low mesh vents are not optional - they're how the tent breathes in. Tape them shut for light-proofing and the whole airflow system falls over.
Step 2: Hang the light
Mount the light to the top crossbars on ratchet hangers so you can raise and lower it one-handed. Start it higher than feels right - a plant can double in flower and come up to meet it, and you can always drop a light. Match the light to the tent footprint, not the other way round: our LED grow lights are sorted by coverage area, and the Lumatek range is what most of our growers settle on.
Step 3: Mount the extraction b fan, filter and ducting
This is the part that controls temperature, humidity and smell all at once, so it's worth getting right. The carbon filter and inline fan go at the top of the tent, because warm, smelly air rises - mount the filter low and it scrubs your cleanest air while the rest leaks out the seams.
Connect filter to fan, run the ducting out the nearest top port in the shortest, straightest run you can manage, and clamp every join. Size the filter to the fan - a mismatched pair either roars or fails to scrub. If you're choosing separately, our carbon filters are listed by airflow rating so you can match them up. Done right, the fan pulls air out through the filter, the tent walls suck gently inward (that's negative pressure), and fresh air gets drawn in through those bottom vents.
Step 4: Add circulation
The extraction fan moves air out; you still need air moving around the canopy. A couple of small clip or oscillating fans do it - point them across the canopy, not straight down at it. Leaves should rustle, not flap. One fan below the canopy and one above beats a single big blast every time.
Step 5: Pots, timer and meters
Pots: we'd start a beginner on fabric pots - they air-prune the roots and drain freely, which is far more forgiving than a solid pot when you're still learning to water. Put a saucer under each one and a builder's tray or liner under the lot, because watering to runoff has to go somewhere that isn't the floor.
Timer: keep the timer and power strip outside the tent - tent humidity corrodes and shorts timers, and a dead timer means lights stuck on or off at the worst moment. Give every cable a drip loop: a U-dip below the exit port so water runs off instead of tracking into the electrics.
Meters: a basic thermo-hygrometer tells you your tent's temperature and humidity at a glance, and a pH and EC meter keeps your feed in range. Growing on numbers instead of guesswork is the single biggest jump a beginner can make.
Before the plant goes in
Run the tent empty for a day. Set the light cycle on the timer, get the extraction balanced so the tent draws gently inward without ballooning, and check your temperature and humidity sit where you want them. Sort the layout, airflow and water management before anything's growing, and the rest of the grow is maintenance rather than firefighting.

FAQ
What do I need to set up a grow tent?
At minimum: a tent, an LED grow light sized to the footprint, an inline extraction fan, a carbon filter, ducting and clamps, a couple of circulation fans, fabric pots, a timer, and a thermo-hygrometer. A pH and EC meter is the next thing to add.
What order do I set up a grow tent in?
Pitch the tent, hang the light from the top crossbars, mount the carbon filter and inline fan up top with ducting to the nearest port, add circulation fans across the canopy, then sort pots, timer and meters. Run it empty for a day before planting.
Where does the carbon filter go in a grow tent?
At the top. Warm, smelly air rises, so the filter and inline fan belong up high where they catch it. Mount the filter low and it only scrubs your cleanest air while the rest leaks out.
Should the timer go inside the grow tent?
No. Tent humidity corrodes and shorts timers. Keep the timer and power strip outside the tent and give every cable a drip loop so water runs off rather than into the electrics.
Where can I buy a grow tent kit in Ireland?
DIG (Dublin Indoor Gardening) stocks Secret Jardin tents and full matched kits b tent, light, fan and filter sized to each other b with collection in Dublin and delivery across Ireland.
