A Masterclass In Indoor Cultivation.  

If you’re serious about growing indoors but don’t fancy spending your evenings elbow-deep in ducting, this is the answer. The Mars Hydro FC4000 EVO Smart Grow Tent Kit is a full-spectrum, fully-automated indoor growing setup with a brain as sharp as it looks. Designed for growers who want commercial-level performance in a discreet, energy-efficient package, it combines premium materials, intelligent climate control and cutting-edge LED technology to deliver outrageous results with minimal effort.

From the first unboxing to your first full harvest, this kit is built to make life easier, quieter, cooler and far more productive. It’s automation without aggravation. Intelligence without overkill. And flavour-friendly, without mentioning, well… you know what.

Mars Hydro FC4000 EVO. Big Flowers & Big Flavours.

The Mars Hydro FC4000 EVO LED Grow Light is the centrepiece of this system - and it’s an absolute monster. Featuring the new Samsung LM301H EVO diodes, it packs an efficiency of 2.85 umol/J and runs at a rock-solid 320w. Expect wall-to-canopy uniformity, high PPFD (up to 912 umol/m²/s) and lower running costs than your air fryer.

It’s full spectrum too, so you get explosive veg and bountiful blooms from seedling to harvest. That classic Mars Hydro red peak delivers exactly the kind of energy plants crave in the flowering phase - without frying your room or your electricity bill. And thanks to passive cooling and a removable driver, the unit runs whisper-quiet and ice-cool. No fans. No hum. No headaches.

But what really sets it apart is the Mars Hydro iConnect system. This light isn’t just powerful - it’s smart. You can automate sunrise and sunset cycles, tweak output intensity remotely, and monitor everything from the Mars Hydro app. Whether you’re on your sofa, in your office, or halfway through a pub lunch, your grow light is still working smarter than half the cast of Dragon’s Den.

Mars Hydro Smart Ventilation System - Climate Autopilot.

Anyone who’s ever grown indoors knows that air circulation and odour control are just as important as lighting. That’s where the Mars Hydro iFresh Extraction Kit comes in.

Let’s begin with the EC fan. It’s silent. Whisper-quiet. The 4-inch version runs at 26.8 dB, which is basically the sound of a monk meditating in a soundproof booth. Yet it moves air like a hurricane in a teacup - 205 CFM at just 27 watts. The 6-inch model steps up with 402 CFM at 62 watts and still whispers sweet nothings at 32 dB.

The real magic, however, is the iFresh climate controller. This little box of wizardry allows you to set temperature and humidity levels in the Mars Hydro App, and then the little sensor takes real-time measurements automatically adjusting fan speed to maintain the perfect climate inside your tent. No more constantly tweaking settings or waking up in a cold sweat worrying that your plants are overheating - the system does all the work for you.

And then, of course, we have the Australian RC412 carbon filter. If you’re growing anything that has anything particularly aromatic, this is your best friend. The activated carbon inside this beast doesn’t just mask smells - it completely eliminates them. No leaks, no lingering odours, no awkward conversations with your neighbours about why your flat suddenly smells like a botanical research facility.

Mars Hydro Slim Grow Tent. 

Mars Hydro doesn’t do things by halves, and their grow tent range is no exception. Measuring in at a slim 120cm x 60cm x 180 tall, this little beauty can fit just about anywhere.

The 1680D Oxford fabric is thick, tear-resistant and completely lightproof, so your plants stay in a perfectly controlled environment without interference from outside light.

Inside, the diamond-pattern reflective mylar boosts light intensity by 25%, ensuring that every beam from the FC400 EVO is maximised for growth. Whether you’re growing leafy greens, herbs or resin-producing plants, this tent ensures zero wasted light & maximum efficiency.

The heavy-duty 0.9mm thick poles and reinforced metal corner adapters can support up to 75lbs of hanging weight, so you can load it up with lights, fans, and whatever other high-tech gadgets you fancy without worrying about it collapsing.

Ventilation is sorted with three duct ports for flexible airflow configurations and a mesh viewing window lets you check on your plants without constantly unzipping the tent and disturbing the climate. And yes, the SBS zippers are built to last - so no frustrating jams or breaks.
