AeroFlux Smart Grow Tent Heater by VIVOSUN — 700W PTC Heater with App Control & VPD Sensing
VSN-AF700
Pairs well with
Cold grow tents drag plant metabolism to a crawl. Nutrient uptake slows, VPD drifts out of range, and night-time temperature swings stress plants right when they should be putting on growth. The VIVOSUN AeroFlux Smart Grow Tent Heater delivers 700W of controlled PTC heating with real-time temperature and VPD sensing, so your grow space stays in the right window through every part of the photoperiod — and you control the whole thing from the VIVOSUN app.
Specifications
Cold nights are where most VPD problems start in Tasmanian and southern mainland grows. Stable temps keep transpiration consistent, which is what actually drives nutrient uptake.
- Set a minimum temperature in the app — let the heater do the work automatically.
- Pair with a Vivosun humidifier to get the most out of your grow. If it's too humid, grab their dehumidifier and let the smart ecosystem balance both sides.
- Watch VPD trends across a full week — that's where you'll spot drift the eye misses.

Frequently asked questions
What size grow tent is the AeroFlux 700W heater suitable for?
It's designed for grow tents up to 1.5m x 1.5m. That covers most home-grow setups — single tents through to mid-sized rooms with reasonable insulation. In significantly larger spaces or extremely cold environments you'll want supplementary heating or a dedicated AC/heat unit like the AeroLush.
Does the heater connect to the VIVOSUN app?
Yes. The AeroFlux pairs with the VIVOSUN app over Wi-Fi for monitoring, scheduling, and integration with other VIVOSUN smart ecosystem gear like the GrowHub and AeroZesh controllers.
Can it actually hold VPD overnight?
Yes, in the spaces it's sized for. The built-in temperature and VPD sensors let it respond automatically to drops in night temperature, which is the single biggest cause of VPD drift in Australian grows during cooler months.
Is it safe to leave running unattended in a grow tent?
Yes. The AeroFlux ships with tip-over cutoff, overheat protection, and flame-retardant housing — all standard requirements for indoor unattended heating. Keep it away from direct fabric contact and ensure airflow around the unit as you would with any heater.
How does it compare to a standard space heater?
A standard space heater has no environmental sensing — it cycles on a basic thermostat with no awareness of humidity or VPD. The AeroFlux holds setpoints based on what plants actually care about, runs five PWM-controlled heat levels for smoother output, and integrates with your wider smart grow setup.
