Spider Farmer. Smart, Stealthy & Affordable.

There are some things in life that are worth splashing out on. A proper mattress. A reliable car. And, if you're the sort of person who enjoys growing things indoors, a grow tent kit that doesn’t turn your spare room into a sweltering, humming, luminous mess. Enter the Spider Farmer SF4000 EVO Grow Tent Kit – a package so well thought-out that it practically grows the plants for you.

With a market-leading Spider Farmer SF4000 EVO LED Grow Light, an intelligent 4” or 6” extraction system, and a top-tier Bay 6 Grow Tent, this kit takes all the hassle out of indoor growing. It’s stealthy, efficient, and built to last – making it the perfect companion for modern growers who want maximum yields with minimal effort (and minimal running costs).

400w of Raw Samsung EVO Power.

Right, let’s start with the brain of this setup – the Spider Farmer SF4000 EVO LED grow light.

This isn't some cheap LED knockoff that flickers like a 90s nightclub and burns out in a week. No, this is cutting-edge tech wrapped up in a rugged aluminium frame that could probably survive a nuclear blast.

At its heart are Samsung LM301H EVO diodes – widely considered the best in the business. These aren’t just bright, they’re stupidly efficient, pushing out an impressive 3.14 µmol/J PPE per diode. In simple terms, that means more light, less electricity, and better growth without the usual heat issues.

And speaking of efficiency, this light only draws 450w but comfortably replaces a 600W HPS/MH system – all while costing less than £1 per day to run. That means you can complete an entire 8-week grow cycle for about £70. Try doing that with an HPS setup and you’ll need to remortgage your house.

It’s fully dimmable, totally silent and thanks to a new 2025 diode layout, the light distribution is even across your entire grow space. No more burnt tops and stunted sides. Plus, the full spectrum output (3000K, 5000K, 660nm red, and 760nm IR) ensures your plants thrive from seedling to harvest.

This is, without doubt, one of the best LED grow lights on the market today – and it’s the reason this kit is such an absolute steal.

Spider Farmer Intelligent Ventilation - Climate Control for the 21st Century.

Now, let’s talk about airflow. Because without proper ventilation, your plants will cook faster than a Sunday roast in a fan-assisted oven.

Thankfully, Spider Farmer has taken care of that with their Intelligent Extraction Kit – a system that doesn’t just move air but actively manages your grow room climate like some sort of botanical butler.

The star of the show is the intelligent controller. Forget fiddling with fan speeds and constantly checking temperatures – this thing does it all for you. Just set your preferred temp and humidity levels, and the system adjusts automatically, keeping your plants in the perfect growing environment.

The EC fan is whisper-quiet (26.8dB on the 4” version, 32dB on the 6”), yet it shifts an impressive amount of air – 205 CFM for the 4” model, 402 CFM for the 6”. That means no heat buildup, no stale air, and (most importantly) no overpowering plant aromas leaking into the rest of your house.

The RC412 activated carbon filter is top-quality too, scrubbing out odours before they escape. So, unless you’re growing something truly exotic, your neighbours will be none the wiser.

Throw in 7 metres of premium black ducting, easy-install duct clips, and a plug-and-play setup, and you’ve got a ventilation system that takes all the stress out of airflow management.

Premium Quality Grow Tent 

British-designed and built like a tank, this tent is strong, discreet, and made to last. The reinforced metal poles and polypropylene corners give it solid stability, meaning it won’t sag or collapse under the weight of your lights and fans.

Inside, it’s lined with 95% reflective Mylar, which boosts light intensity by 30% compared to standard grow tents. That means bigger yields without needing more wattage.

The light-sealing zippers and drawstring ducting ports keep everything locked down tight, so you won’t get annoying light leaks or unwanted airflow messing up your environment.

Available in three sizes – 1.0m x 1.0m x 1.8m (with 4” extraction), 1.0m x 1.0m x 2.0m (with 4” extraction), and 1.2m x 1.2m x 2.0m (with 6” extraction) – this kit can fit neatly into bedrooms, hallways, basements or even a well-ventilated cupboard.

Easy to assemble, PVC-free, and built with stealth in mind, this tent is everything you need for a successful grow – and nothing you don’t.

A No Brainer for Growers on a Budget. 

If you’re looking for a reliable, high-performance grow tent kit that won’t bankrupt you in running costs, the Spider Farmer SF4000 EVO Grow Tent Kit is as good as it gets.

With one of the best LED grow lights on the market, a state-of-the-art ventilation system, and a tough, stealthy grow tent, this kit is perfect for anyone who wants big yields without the usual headaches.

It’s powerful enough for experienced growers, yet simple enough for total beginners. And at this price, it’s an absolute bargain.

So, whether you’re setting up a covert spare room grow or just want a no-fuss, high-yield setup, this kit is the smart choice. Get it, set it up, and watch your plants thrive – while you sit back and enjoy the savings.
