Most grow spaces don't need a blast of hot air — they need a few degrees held steady through a cold night. The Horti Air Heat Saber is a slim radiant tube heater that does exactly that. Mount it to the wall, floor or ceiling on the included bracket, plug it into a thermostat, and it quietly keeps the chill off your tent or grow room without fans, noise or floor space lost. Three tube lengths cover spaces from a propagation corner to a full room, and matching clip-on heat shields (sold separately) keep the heat off your canopy.
Specifications
Grower's Tip
- Running a chilly tent at night? Put the 60W Saber on a thermostat set a few degrees above your ambient target. It only draws power when the temperature dips, so you save on running costs while keeping cold stress off your plants.
- Radiant heat warms the surfaces it faces, not just the air. Mount the tube low and let warmth rise through the canopy rather than pointing it at the plants.
- Fit the matching shield whenever the tube sits close to foliage or tent fabric — it directs heat where you want it and keeps leaves from cooking.
- A small circulation fan spreads the warmth evenly and stops a warm ceiling sitting over a cold floor.

Frequently Asked Questions
Will it heat a cold garage or shed?
No — and it isn't meant to. The Heat Saber maintains warmth in a mildly cool space; it won't lift a near-freezing garage to grow temperature. For that job you want a fan-forced unit like the VIVOSUN AeroFlux or AC Infinity Thermoforge T7, or heat the tent rather than the room.
Which size do I need?
Work off the volume you're keeping warm: the 60W (31cm) tube suits compact setups and tents up to about 2m³, the 120W (61cm) suits mid-size tents around 3–4m³, and the 240W (122cm) covers larger spaces around 5–6m³. On a thermostat, going one size up costs nothing in practice — it just reaches the set point faster.
Do I need a heat shield?
If the tube mounts close to plants, tent walls or anything heat-sensitive — yes. The matching shields clip on and deflect radiant heat away from the canopy, so you can run the heater in a tight tent without scorching the leaves nearest to it. In a roomy space with the tube mounted well clear of plants, you can run without one.
Does it hold a set temperature on its own?
No — on its own it runs whenever it's plugged in. The built-in overheat protection is a safety cutoff, not a thermostat. Pair it with a plug-in thermostat controller like the Cultiv8 Thermostat, set your minimum, and it becomes fully automatic.
Is it safe inside a humid grow tent?
Yes — the IP55 rating means it's protected against dust and low-pressure water jets, so tent humidity, misting and the odd splash won't bother it. Mount it on the included bracket with its 89mm standoff, keep it clear of fabric and pooling water, and it's built for exactly this environment.
Where did the tube + shield combinations go?
Shields now live on their own page — Heat Shields by Horti Air — in all three lengths. Pick your tube here, add the matching shield there, and both land in the same cart.
