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.

Know what you're buying. This is a radiant tube heater built to maintain warmth in a mildly cool space — not to fix a freezing shed in a Tassie winter. If your space drops near zero, look at a fan-forced unit like the AeroFlux or Thermoforge T7 instead.
Gentle Background HeatRadiant warmth with no fan and no noise. It lifts and holds the ambient temperature instead of blasting one hot corner and cycling off.
IP55 Sealed For Grow RoomsRated against dust and water jets, so it lives happily in the humid, misty environment inside a tent or greenhouse where ordinary heaters shouldn't go.
Mounts Anywhere, Uses No Floor SpaceThe included bracket fixes it to wall, floor or ceiling with an 89mm standoff that keeps heat off the mounting surface. Your pots keep the floor.
Three Lengths, Sized To Your Space60W (31cm) for spaces up to ~2m³, 120W (61cm) for ~3–4m³, 240W (122cm) for ~5–6m³. Pick the tube that matches the volume you're keeping warm.
Thermostat-ReadyLow draw means a simple plug-in thermostat runs it perfectly. Set your target once and the Saber only draws power when the temperature actually dips.
Shield-CompatibleMatching clip-on shields (sold separately) deflect heat away from leaves — the difference between a warm tent and scorched foliage when space is tight.

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.

How To Set It Up

1Pick your tube by space volume — 60W for up to ~2m³, 120W for ~3–4m³, 240W for ~5–6m³. When in doubt between two sizes with a thermostat in play, go bigger; the thermostat stops it overshooting.
2Fix the bracket to your wall, floor or ceiling. The bracket holds the tube 89mm off the surface — keep that clearance and keep the tube away from fabric and cables.
3Adding a heat shield? Clip it on if the tube sits near plants or tent walls, angled to deflect heat away from the canopy.
4Plug it into a thermostat controller, hang the thermostat's probe at canopy height, and set your minimum temperature.
5Check your min/max thermometer after the first cold night and adjust the set point. Small radiant heaters reward patience — give each change a full night before judging it.

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.

Growers First, Retailers Second

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
