The fan lives on the tent roof, the controller sits on the wall, and the power point is always on the wrong side of the room. Cultiv8 extension leads close that gap without a chain of double adaptors and borrowed leads. Each one is a single-socket 240V lead with a standard Australian 3-pin plug, made in five lengths: 3m for inside the tent, 5m from wall to tent, 10m and 15m to cross a room, and 20m for a shed or garage grow space. Every lead is rated to 10A, which is 2400W in total, so it suits fans, timers, heaters, pumps and lighting as long as the combined load stays under that. One socket, no switch, no surge protection: a plain lead that does one job properly.

10A is the limit for everything on the lead. Add up the wattage of whatever runs off it and keep the total under 2400W. Heaters and big lights use that budget fast. And one lead per run: never plug extension leads into each other.
Five lengths, so you never join leads3m, 5m, 10m, 15m or 20m. Buy the run you actually need instead of plugging two short leads together, which is the unsafe way to get there.
Standard Australian plug and socketFlat-earth 3-pin at both ends. Fits every standard power point and every standard appliance plug, with no adaptors in between.
Rated to 10A, 2400WThe full rating of a standard Australian power point, so a fan, a timer and a small heater can share one run if the total stays under 2400W.
White cable you can find in the darkEasy to spot on a grow room floor and easy to trace back to the wall when something trips mid-cycle.
Add it to the order, skip the hardware runPriced like a lead, not a grow gadget. Throw the length you need in with your fan or heater and it turns up in the same box.
Made for the Cultiv8 kitSame brand as the Cultiv8 timers, thermostats, tube heaters and inline fans it ends up powering.

Grower's Tip
  • Uncoil the whole lead before it carries a load. A coiled lead running a heater or a big light builds heat in the coil.
  • Add up the watts from the labels on your gear, not from memory. A 2000W heater plus a fan and a light is already over the limit.
  • Keep the plug and socket join off the floor and well clear of reservoirs, trays and anywhere runoff collects. A cable tie on a tent pole does the job.
  • Pick the shortest length that reaches without pulling tight. Less spare cable means less to trip on and less coiled up behind the tent.
  • Route the lead through a tent cable port, not the door zip. A zip pinches the cable every time it is opened and closed.
  • Look the lead over between grows. Cuts, crushed sections or scorched pins mean it is time for a new one.

How To Set It Up
1Measure the path the cable will actually take from the power point to the gear, up walls and around door frames, then choose the next length up.
2Add up the wattage of everything that will run off the lead and check the total is under 2400W.
3Uncoil the full lead and run it through a cable port in the tent rather than the door zip.
4Secure the lead off the floor with cable ties or hooks, keeping the socket end away from water.
5Plug your gear into the lead first, then plug the lead into the wall and switch on.

Frequently Asked Questions
What can I run on a Cultiv8 extension lead?

Anything with a standard Australian plug, as long as the total load stays under 10A, which is 2400W. Fans, timers, controllers, pumps, heat mats and most grow lights fit easily. Add up the wattage on each label before you plug in.

Can I plug two extension leads together?

No. Daisy-chaining leads is a known overheating risk and is not recommended under Australian electrical guidance. Buy a single lead long enough for the whole run: that is why these come in five lengths.

Will it take my HID reflector or ballast plug?

No, not if that plug has a round earth pin. Some HID reflector and ballast leads use round-earth plugs, which will not fit this flat-earth socket. Standard flat-earth plugs fit fine.

Which length do I need?

Measure the path the cable will actually follow, then go one length up. As a rough guide: 3m inside a tent, 5m from a wall point to a tent, 10m or 15m across a room, and 20m for a shed or garage grow space.

Can I run a heater on it?

Yes, within the 10A rating. A heater is usually the biggest load in the room, so check its wattage, count everything else on the same lead, and uncoil the lead fully before the heater runs.

Can I use it outdoors?

No. Treat these as indoor leads. Cultiv8 does not publish a weatherproof rating for them, so keep them inside, dry and off wet floors.

Does it have a switch or surge protection?

No. It is a plain single-socket lead. Switch your gear at the wall or with a timer or controller on the run.

Do you ship them Australia-wide?

Yes. They ship from our Launceston store to anywhere in Australia, with free shipping over $499*.

Growers First, Retailers Second

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
