Grow Room Temperature Control
Grow room temperature control that keeps your grow in range — grow tent heaters, heat mats, thermostats and smart temp-driven fan controllers, stocked in Australia and backed by 14 years of growing.
Grow Room Temperature Control for Every Season
Cold snaps stall roots and heat spikes cook canopies. This range covers both ends — heat when Tasmania-grade winters bite, and automated fan speed when summer pushes temps up.
Grow Tent Heaters That Hold Overnight Temps
The Horti Air Heat Saber heat bars deliver steady radiant warmth with overheat protection and flexible mounting — built for lights-off dips and winter grows in tents, rooms and greenhouses.
Heat Mats & Thermostats for Propagation
Warm roots strike faster. Cultiv8 and VIVOSUN heat mats pair with plug-in thermostats — or grab AC Infinity's SUNCORE H3 with its digital temperature controller built in (240V AU) — for set-and-forget root-zone warmth.
Smart Controllers That Automate Grow Room Temperature Control
Fan-Tastic and SigilVentus smart controllers use thermal probes to ramp your exhaust fan as temps climb and ease off when the room cools — the Pro model reads humidity too.
Dial in the rest of your climate: humidity control, grow room monitors, environment controllers and the full grow room environment control range.
FAQs
What temperature should a grow tent be?
Most indoor plants grow best between about 20°C and 28°C with lights on, and a few degrees cooler at night. A heater with a thermostat holds the low end; a temp-driven fan controller manages the high end.
Do I need a heater for my grow tent in winter?
Yes, if lights-off temperatures drop below your target range. A thermostat-controlled heat bar or heat mat keeps overnight temps stable without running all day.
Can a fan controller manage grow room temperature?
Yes. Smart controllers with thermal probes speed your exhaust fan up as the room warms and slow it as it cools, so temperature stays in range automatically.
Do heat mats need a thermostat?
Yes, ideally. Most heat mats run at full power on their own — a thermostat holds a set root-zone temperature and stops seedlings overheating.
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.
