Automated Heat Management.

There are few things more infuriating in indoor growing than temperature drops. One minute everything’s ticking along nicely, the next your grow room feels like a Victorian conservatory in February. Growth slows, metabolism sulks and suddenly you’re chasing problems that never needed to exist in the first place.

Introducing the Spider Farmer Grow Tent Heater - a purpose-built, grow-safe heating solution designed specifically for controlled indoor environments.

This isn’t a repurposed household heater shoved into a tent and hoped for the best. This is a 540w, smart-controlled, ductable, sensor-driven heat management system built by people who understand that temperature stability is not optional - it’s fundamental. 

Smart Heating That Thinks For You.

The headline feature here is smart control, and Spider Farmer hasn’t half-arsed it. Once paired with the GGS (Genius Grow System) controller or compatible power kits, the heater integrates directly into the Spider Farmer app. That means real-time temperature monitoring, remote control, automated scheduling, and zero guesswork.

You can set target temperatures, program day and night modes, and let the heater make the micro-adjustments automatically. If temperatures drop below your chosen threshold, it switches on. Once stability is restored, it backs off. No overshooting, no constant cycling, no drama.

This is proper closed-loop temperature control - the kind that keeps environments stable instead of swinging wildly between “too cold” and “why is it so warm in here?”.

Heating Done Properly. 

At the heart of the unit sits advanced PTC heating plates, paired with PWM intelligent control. In plain English, this means fast heat-up times, consistent output, and excellent energy efficiency. You get 10 adjustable heat levels, allowing the system to dial in exactly the amount of warmth required rather than blasting full power every time.

With a maximum output of around 540w, the heater delivers more than enough warmth for grow tents and rooms without hammering your electricity bill. It’s powerful when it needs to be, restrained when it doesn’t - which is exactly how heating should behave.

Day & Night Temperature Regulation.

One of the genuinely clever features is the built-in day/night temperature logic. Plants don’t experience the same temperatures around the clock in nature, and this heater understands that.

You can program higher daytime temperatures and cooler nighttime targets, allowing the system to follow natural temperature rhythms automatically. This supports healthier metabolic processes, reduces stress, and keeps growth patterns consistent - especially during demanding flowering periods where temperature swings can cause real problems.

The heater detects day and night cycles via the connected sensor, switching modes automatically without you lifting a finger.

Intelligent Temperature Control.

Instead of dumping hot air straight into the tent like an angry hairdryer, the Spider Farmer Grow Tent Heater uses a 160cm adjustable vent hose to deliver warm air precisely where it’s needed.

This duct-style design allows heat to be dispersed evenly across the canopy area without blowing directly onto plants. It eliminates hot spots, prevents leaf stress, and creates a uniform temperature throughout the space. You can route the hose into the centre of the tent, along a wall, or wherever distribution makes the most sense.

Placement is flexible too. The unit can sit flat inside the tent for rapid heating or stand upright outside the tent to save space and keep things tidy.

Multiple Layer Protection. 

Heating indoors demands proper safety engineering, and this is where Spider Farmer has gone all-in. The heater is built using high-grade flame-retardant materials, exceeding V0 standards and meeting 5VA safety ratings.

It features multiple layers of protection, including hardware-level overheat safeguards and environmental temperature shutdowns. If internal temperatures exceed safe limits, heating shuts off while the fan continues to run. If the external sensor detects excessive ambient heat, the system cuts heating automatically until conditions stabilise.

In short, it’s designed to fail safely - which is exactly what you want from a heater running in an enclosed environment.

Suitable For Drying Rooms.

The Spider Farmer Grow Tent Heater doesn’t clock out once growth is done. It’s equally useful during the drying stage, working alongside dehumidifiers to provide controlled warmth and airflow. This ensures consistent moisture reduction without overdrying or uneven results.

The built-in fan-only mode allows it to function as an air mover when heat isn’t required, adding extra versatility to the setup.

And yes, setup is refreshingly painless. Plug in the RJ12 cable, power it on, pair it through the app, and you’re off. The display is clear, the controls are intuitive, and even the temperature readings line up closely with independent sensors - always a reassuring sign.

Complete Temperature Management.

The Spider Farmer Grow Tent Heater isn’t just a heater. It’s a temperature management system designed specifically for indoor growing environments. Smart app control, precise PTC heating, day/night automation, excellent airflow design, and serious safety credentials make this an essential bit of kit for anyone growing year-round.

If you’re tired of chasing temperatures, battling seasonal drops, or relying on crude household heaters that don’t belong anywhere near your grow space, this is the upgrade that quietly transforms everything.

Set it once. Trust it completely. And let your plants stay warm, calm, and consistently productive - no matter what’s happening outside.
