Quick Answer
Cultiv8 Tube Heater Heat Bars are compact electric tube heaters for sheltered greenhouses, grow tents and propagation areas that need gentle background heat. They suit home growers and controlled-environment gardeners choosing between five live variants—60W 30CM, 80W 61CM, 120W 61CM, 180W 90CM and 240W 120CM. Every listed model operates at 220–240V, 50Hz and uses an IP55-rated housing with a self-resetting thermal cut-out. Select a size for the space, insulation and ambient conditions, then monitor temperature; a separate compatible controller can provide thermostatic switching.
Product Description
The Cultiv8 Tube Heater provides low-level background heat in compact growing spaces without taking up the floor area of a large portable heater. Its slim white tube can be mounted securely on a wall or supported on the supplied-style feet, making it practical for greenhouse edges, grow-tent walls and propagation areas.
This listing covers the five Cultiv8 models currently offered by TG Hydroponics. Output and physical length change by variant, while the supply voltage, frequency, IP55 rating and built-in thermal safety protection remain consistent. The heater becomes very hot in operation, so correct mounting, clearance and supervision are essential.
Key Features
- Five power and length options: 60W to 240W, with Shopify variants from 30CM to 120CM.
- IP55-rated housing: designed with an ingress-protection rating; this does not make the heater suitable for immersion or outdoor use in damp weather.
- Thermal cut-out: the safety device switches the heater off if it overheats and resets after the unit cools.
- Flexible mounting: install securely on a wall or floor using the correct brackets or feet; never place the tube directly on the floor without its feet.
- Optional temperature control: compatible with the Cultiv8 Heat Mat & Tube Heater Controller for thermostat-based switching.
- One-year limited warranty: the Cultiv8 manual states one year from purchase for qualifying defects in materials or workmanship, subject to proof of purchase and the stated exclusions.

Directions for Use
- Inspect the heater and power cord before use. Do not operate the unit if the cord or heater is damaged.
- Keep the heater disconnected from power while installing it.
- Fit the mounting brackets and secure the heater to a suitable wall or stable floor position. Do not energise the heater until it is firmly mounted, and never place it directly on the floor without its feet.
- Keep the power cord away from the hot tube. Do not position the heater directly below a power outlet, and keep it clear of flammable materials.
- If thermostatic control is required, connect the heater to a compatible Cultiv8 controller according to that controller’s instructions.
- Connect power only after installation is complete. The surface becomes very hot: do not touch or cover the heater.
- Switch the heater off when it is not required or will be left unattended.
Care and Maintenance
- Unplug the heater and allow it to cool completely before cleaning or handling.
- Wipe with a damp cloth, then dry with a soft cloth.

- A small amount of vapour during approximately the first five minutes of initial operation can be normal as production lubricant clears.
- If the power cord is damaged, stop using the heater and arrange service through the manufacturer, warranty provider or a qualified person.
- Retain the instruction manual for safety and warranty reference.
Frequently Asked Questions
What is the Cultiv8 Tube Heater used for?
It provides gentle background heat for sheltered greenhouses, grow tents and propagation areas. It is intended for growers who need a compact heater near the perimeter of a controlled growing space.
Which Cultiv8 Tube Heater sizes are available?
This Shopify listing offers 60W 30CM, 80W 61CM, 120W 61CM, 180W 90CM and 240W 120CM variants. Select the option that suits the space, insulation and ambient conditions.
Does the heater include a thermostat?
No integrated thermostat is stated for these heaters. For thermostatic switching, pair the selected model with the compatible Cultiv8 Heat Mat & Tube Heater Controller, sold separately.
Can the Cultiv8 Tube Heater be mounted on a wall or floor?
Yes. The manual permits wall or floor mounting when the heater is secured with the correct brackets or feet. Never operate the tube loose or directly on the floor without its feet.
Is an IP55 heater waterproof or suitable outdoors?
No. The heater has an IP55 rating, but the Cultiv8 manual says not to use it outdoors in damp weather or submerge it. Follow the manual and keep electrical connections dry.
What happens if the heater overheats?
A built-in thermal cut-out switches the heater off if it overheats. The device resets after the heater cools, but the cause of overheating—such as covering or blocked clearance—must be corrected before continued use.
Does the tube become hot to touch?
Yes. The manual warns that the tube becomes very hot during operation. Do not touch or cover it, and allow it to cool fully before cleaning or moving it.
Is a slight vapour normal on first use?
The manual notes that a small amount of vapour can appear for about the first five minutes as production lubricant clears. Stop use if the unit is damaged or shows any other unsafe condition.
How should the Cultiv8 Tube Heater be cleaned?
Disconnect power, allow the heater to cool completely, wipe it with a damp cloth and dry it with a soft cloth. Do not use abrasives or metal polish.
What warranty applies?
The manufacturer manual states a one-year limited warranty from the date of purchase for qualifying defects in materials or workmanship. Proof of purchase and the manual’s warranty conditions and exclusions apply.
