Most failed starts come down to the same few things: cold roots, trays that dry out or stay soggy, and a dome nobody vented. The VSeed S40 by VIVOSUN is an all-in-one propagator that takes those jobs off your hands. It runs a 30W full-spectrum LED, automated ebb & flow watering, 40W root-zone heating and an intake and exhaust fan pair, all reading off sensors for dome temperature, humidity and root temperature. Three presets cover germination, rooting and seedlings, and you can run it from the onboard screen or the VIVOSUN app. It suits home growers starting seeds or taking cuttings who want consistent results without babysitting a tray. Know the limits before you buy: it holds 40 cells with 17 cm of grow height, so it is built for starts and cuttings, not for big mothers or full flats of seedlings.

Australian model. This is the VSS-VSS40-AU, supplied with a 240V power adapter and an Australian plug. The app connects over 2.4 GHz Wi-Fi only, so check your router has a 2.4 GHz band before you set it up.
Warm Roots in a Cold RoomThe 40W ThermoFlow system heats water in the base and circulates it under the tray. VIVOSUN rates it to lift root temperature by up to 10°C in a 15°C room, with a settable target of 20–32°C. No separate heat mat or thermostat to buy.
Waters Itself, Then DrainsEbb & flow floods the tray for 10 minutes, 30 minutes after the light comes on, then drains so roots get air. A full 4 L tank lasts about two weeks by VIVOSUN's figure, and the screen and app warn you when it runs low.
Vents Itself TooA standard dome only vents when you remember to crack it. The VSeed's intake and exhaust fans kick in when dome humidity or temperature passes your set point, which keeps damping-off and mould in check.
Three Stages, PresetGermination, Rooting and Seedling modes set light, root temperature and humidity for each stage. Every value can be changed: root temperature, humidity trigger, light intensity, light duration and light-on time.
Root Temp and VPD on ScreenMost propagators tell you nothing. The LCD shows dome temperature, humidity, root temperature and VPD, and flags anything out of range. The app shows the same remotely and sends alerts.
Even Light, Edge to EdgeThe 30W full-spectrum LED uses lenses to spread light across the whole tray, so the outside cells do not stretch while the middle ones thrive. Intensity runs from off to level 5.

Grower's Tip

  • Cuttings and light: plenty of growers root cuttings under 24 hours of light. It is plant-specific, though, and some varieties root better with a few hours of dark. The Rooting preset ships at 18 hours on, 6 off, and light duration is adjustable in the stage settings, so set it for what you are rooting.
  • Keep it out of your flowering space. The LED and the LCD both give off light. Run the VSeed in a separate room or your veg area, never inside a tent or room on a dark cycle. Turn the screen brightness down in the system settings if it sits anywhere light matters.
  • Check the water before a Quick Irrigation. Automated watering waits for the heated water to cool to a safe temperature. A manual Quick Irrigation (long-press Down) runs straight away without that check, so feel the water first.
  • Start weak. VIVOSUN's own guide fills the tank with a light nutrient solution at pH 5.5–6.0 and EC 0.6–0.8 (300–400 ppm) from germination on. Test through the port in the water fill cover without lifting the dome.
  • Give it room to breathe. Keep at least 10 cm clear around the vents, and sit it on a flat, water-resistant surface, not carpet or good timber.
  • Clean between rounds. The trays are reusable. Wash them and wipe out the reservoir after each cycle, but never submerge the base or hose down the lid. The electronics are not waterproof.
  • A cold Tassie shed is the real test. The heater is rated to lift roots about 10°C above a 15°C room. In a space colder than that, expect it to fall short of a 25°C target, so put it somewhere a bit warmer in winter.

How To Set It Up

1Assemble. Push the water level indicator into its hole in the base, sit the clear dome on top, and connect the base to the lid with the Type-C cable.
2Fill the tank. Pour your solution in through the water fill cover and watch the level indicator. Stop at 4 L and do not overfill.
3Power on and pick a stage. Plug in the adapter, set the clock with the Up and Down buttons, then choose Germination, Rooting or Seedling and press OK. Long-press Menu at any time to change that stage's settings.
4Pair the app. Install the VIVOSUN app, tap + to add the VSeed, and name it. Your phone needs Bluetooth on and a 2.4 GHz Wi-Fi network. Once connected, the clock sets itself.
5Load the tray. Seat your plugs in the tray and long-press Down for a Quick Irrigation to soak them. Plant sprouted seeds root-down or set your cuttings, close the dome, and run the Rooting stage.
6Move to Seedling. Once the seed leaves have opened and true leaves start to show, switch to the Seedling stage. Top up the tank when the low-water alert comes on.

Frequently Asked Questions

Is this the Australian 240V model?

Yes. We sell the VSS-VSS40-AU, which comes with a 240V power adapter and an Australian plug. The unit itself runs on 12V from that adapter.

Can I root cuttings in the VSeed S40?

Yes. VIVOSUN built it for both seeds and cuttings, with a dedicated Rooting stage and 17 cm of grow height under the light. Trim longer cuttings to fit, and set the light duration for the plants you are rooting.

Do I need a separate heat mat?

No. The VSeed has 40W root-zone heating built in, which holds a root temperature you set between 20°C and 32°C. VIVOSUN rates it to lift roots up to 10°C above a 15°C room, so in a colder space it may not reach a high target.

How often do I need to refill the tank?

About every two weeks. VIVOSUN says a full 4 L tank keeps plants watered for roughly that long, and a low-water alert shows on the screen and in the app when it needs topping up.

Does it work without Wi-Fi or the app?

Yes. The onboard buttons and LCD run every stage and setting. The app adds remote monitoring, alerts and scheduling from your phone. It connects on 2.4 GHz Wi-Fi only.

Can I run it inside my flowering tent?

No. The grow light and the screen both give off light, and the clear dome lets it out. Inside a tent or room on a dark cycle, that light leak can upset photoperiod-sensitive plants. Keep it in a separate space.

Can I change the preset settings?

Yes. For each stage you can change the target root temperature, the dome humidity trigger, light intensity, light duration and the daily light-on time, either on the unit or in the app.

Can I check pH and EC without opening the dome?

Yes. The water fill cover lifts out to leave a 2.7 x 3.3 cm port, which fits most pen meters, so you can test the tank with the dome still on.

What warranty does it have?

VIVOSUN covers the VSeed S40 with a 2-year limited warranty from the date of purchase. That sits on top of your rights under Australian Consumer Law.

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.
