VIV-COMBO-CLIMATE-H19-AF700
Pairs well with
VPD is the single biggest lever on plant growth most home growers leave on the table. The VIVOSUN Smart Climate Combo pairs the AeroStream H19 19L smart humidifier with the AeroFlux 700W smart PTC heater — two app-connected pieces that work as one ecosystem to hold temperature and humidity exactly where you want them, day and night. Save $50 versus buying them separately, and lock in tight VPD control through every stage of the grow.
What's in the Combo
19L ultrasonic with WiFi + external canopy probe

- Humidity without heat means cold-night humidity spikes and bud rot risk in flower.
- Heat without humidity means dry-air stress in veg and stalled clones.
- Running both through one app gives you VPD control instead of two disconnected dials.
- Set your VPD target once and the two units cooperate to hold it — no manual juggling.

FAQ
What size grow space does this combo suit?
Yes — both units are sized for tents up to 1.5m x 1.5m and small grow rooms. The H19's 19L tank covers humidity for that footprint comfortably, and the AeroFlux 700W heater is rated for the same range. For larger spaces, you'd want to step up to a dedicated climate unit like the AeroLush C08.
Do both units run from the same app?
Yes. Both the AeroStream H19 and the AeroFlux 700W connect over WiFi to the VIVOSUN app. You'll see live readings, set targets, schedule them around your photoperiod, and get alerts for low water or fault states — all from one phone.
Can they actually hold VPD overnight?
Yes — that's the main reason to run them as a combo. Night temperature drops are the biggest cause of VPD drift in Australian grows. The AeroFlux holds temperature, the H19 holds humidity, and the AeroFlux's built-in VPD sensor lets you watch the result in real time.
How much am I saving compared to buying separately?
You're saving $50. Bought individually the AeroStream H19 is $289.00 and the AeroFlux 700W is $199.99 — $488.99 combined. This combo is $439.95, a 10% saving across the pair.
Do I need anything else to run this setup?
You'll want a circulation fan and an extraction fan if you don't already have them — both units rely on airflow to distribute climate evenly through the canopy. A separate environmental monitor is optional but useful as an independent cross-check on the built-in sensors.
Is the combo shipped as one box or two?
Shipped as two boxes from our Invermay, Tasmania warehouse — they're separate units, but they arrive together as one order. Free shipping on orders over $499* applies; this combo sits just under, so adding a small accessory tips you over the threshold.
Do you ship Australia-wide?
Yes. We ship Australia-wide from Invermay, Tasmania. Free shipping on orders over $499*. Prices are GST inclusive.
