How do I pick the right size?

Our coverage guide assumes your grow space is snug and insulated. If you’re running the bar in a spot that cops the outside chill—think backyard shed or open patio—go the next size (and wattage) up. As a rule of thumb, these bars bump the ambient temp by about 8-10 °C, but how much heat you hang on to comes down to how drafty the space is.

Frequently Asked Questions (FAQ)

What does the Cultiv8 Tube Heater do, and how much heat does it provide?

The Cultiv8 Tube Heater provides gentle background warmth for grow tents, greenhouses, and small rooms. In an insulated setup, it can raise temperatures by around 8–10°C. It’s not a fan heater—it’s best for steady, low-watt heat rather than intense blasts.

How do I choose the right size Cultiv8 Tube Heater for my grow space?

Match the heater’s wattage to your space volume: 60W for ~2m³, 120W for ~3–4m³, etc. For drafty or uninsulated areas like sheds or patios, go one size up. Two smaller bars can sometimes heat more evenly than one large unit.

Is the Cultiv8 Tube Heater safe to run continuously?

Yes—it's designed for 24/7 use and includes built-in thermal protection. The surface gets hot during operation, so avoid touching it while running and keep it away from pets or flammable materials.

Is the Cultiv8 Tube Heater safe for humid environments?

Yes—it’s IP55 rated, meaning it can handle high humidity and light splashes. Just don’t submerge it or let water pool around plugs. Keep connections dry and avoid spraying water directly onto the unit.

Where and how should I install the Cultiv8 Tube Heater?

Mount it horizontally using the included hardware—on a wall or floor is fine. Keep it low in the tent or greenhouse, away from tent fabric, plastic, or pots that could block airflow. Allow clearance around it for safe operation.

Does the Cultiv8 Tube Heater need a thermostat or timer?

It runs continuously, but pairing it with a thermostat gives you better control and efficiency. It works well with controllers like Inkbird or Cultiv8 thermostats. A timer can be used, but thermostats offer smarter temp-based automation.

How much power does the Cultiv8 Tube Heater use, and can I run it on a smart plug?

Power use depends on the model: 60W uses ~1.44kWh per day; 240W uses ~5.76kWh. Multiply that by your electricity rate to estimate cost. You can use a smart plug if it’s properly rated, but a thermostat controller is more precise.

Why isn't the Cultiv8 Tube Heater raising the temperature much?

Common issues include a tent that's too drafty, an overpowered extraction fan, or using an undersized heater. Try insulating the space, reducing fan speed, warming the lung room, or upgrading to a higher wattage model.

Can the 240W Cultiv8 Tube Heater be shipped via Australia Post or qualify for free shipping?

No—the 240W (120cm) heater exceeds Australia Post size limits and is excluded from free shipping promotions. It requires alternate courier delivery.

Where can I use the Cultiv8 Tube Heater?

It’s ideal for tents, greenhouses, drying rooms, small grow rooms, and even sheds. Also suitable near LED setups, CO₂ gear, or reptile/pet areas (with supervision). Just avoid outdoor exposure and always mount securely.

Can the Cultiv8 Tube Heater help prevent plant stress or condensation?

Yes—by providing stable warmth, it helps avoid overnight cold dips, root shock, or humidity spikes that lead to condensation and mould. It’s especially useful during winter or in flower/drying stages.

How do I clean and maintain the Cultiv8 Tube Heater?

Let it cool down, then wipe with a dry or lightly damp cloth. Don’t spray it directly or use cleaners. Occasional dusting and dry plug checks are usually all the maintenance it needs.

What’s the best way to use the Cultiv8 Tube Heater safely and effectively?

Mount it with proper clearance, don’t cover it, and avoid placing items directly on or against it. Use a thermostat for precise control and keep cables off damp floors. Don’t undersize it for your space—it’s designed to maintain warmth, not blast heat.
