The short version

  • Each has a real cost: Galcon distribution and support run through regional wholesalers, so in markets where Galcon has no strong distributor you get the hardware and very little else.; Teralytic the company is reported at around six employees, so if it stops trading the buried probes become inert hardware, which is the single biggest risk in a multi-year soil sensing deployment.
  • They diverge on capability: Galcon covers Battery DC controllers, Teralytic covers Wireless NPK sensing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Galcon

  • Distribution and support run through regional wholesalers, so in markets where Galcon has no strong distributor you get the hardware and very little else.
  • The cloud software is functional rather than refined, and its third-party integration list is short compared with Hunter Centralus or Rain Bird IQ, which matters if you want irrigation data in a wider asset system.
  • Battery-powered controllers mean battery replacement schedules across a large estate, and a dead battery on a remote valve is a silent failure that shows up as a dead planting bed weeks later.
  • No pricing is published for hardware or cloud subscriptions, and pricing varies by country and wholesaler, so budgeting a municipal rollout requires several quotes.
  • The product range is broad and fragmented across GSI, GSI PRO, Galileo Cloud and legacy timers, which makes it genuinely hard to work out which product line a given site should be on.

Teralytic

  • The company is reported at around six employees, so if it stops trading the buried probes become inert hardware, which is the single biggest risk in a multi-year soil sensing deployment.
  • No current pricing is published and reported figures have moved between roughly 300 and 500 US dollars per probe per year, so a buyer cannot model the cost of a hundred-probe deployment without a quote.
  • The subscription is mandatory for the probe to report at all, so the up-front hardware payment buys nothing durable and a lapsed account means a field full of dead instruments.
  • In-field NPK sensing is scientifically contested and readings need interpretation against soil type and calibration, so agronomists will not treat the numbers as interchangeable with a lab test and many will insist on both.
  • Spatial coverage is the unsolved problem: a probe measures one point, soil varies over metres, and covering a field properly multiplies both the hardware and the annual subscription by the number of zones you care about.

Questions people ask

Is Galcon or Teralytic better?
Neither clearly leads. Galcon starts at On request and Teralytic at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Galcon or Teralytic?
Galcon starts at On request and Teralytic at On request.
Does Galcon or Teralytic run on more platforms?
Both run on Web, iOS, Android, so platform support will not decide this one for you.
What is Galcon best used for?
Galcon is most often used for a parks department scheduling roadside and median planting beds where no valve has mains power, an orchard automating block irrigation without trenching electricity to every valve, a greenhouse dosing fertiliser to ec and ph targets alongside climate control, a landscape contractor managing irrigation across dozens of client sites from one cloud account. Of those, a parks department scheduling roadside and median planting beds where no valve has mains power and an orchard automating block irrigation without trenching electricity to every valve are not what Teralytic is typically brought in for.
What can Galcon do that Teralytic cannot?
Galcon covers Battery DC controllers, GSI cloud, Galileo Cloud, Fertigation control. Teralytic covers Wireless NPK sensing, Three-depth profile, Soil respiration and aeration, Long-range radio uplink.

Answered from the vendors’ own pages

Galcon: Do Galcon controllers need mains power?

The DC range does not. They run latching solenoids from internal batteries, which is the main reason they are specified where getting power to the valve is expensive.

Teralytic: Can I buy the probe without a subscription?

No. The probe reports through Teralytic’s network into its cloud, and without an active subscription it does not deliver data.

Galcon: Is there a cloud subscription?

Yes for the connected GSI and Galileo Cloud products. Terms are quoted by controller count and vary by country along with cellular charges.

Teralytic: Does it replace lab soil tests?

No. It gives continuous in-season trend data. Most agronomists will still want lab results for absolute nutrient values and for compliance records.

Galcon: Can it control fertigation?

Yes. Galcon makes dedicated fertigation and greenhouse climate controllers with EC and pH monitoring, sold as separate systems from the field controllers.

Teralytic: How much does it cost?

Teralytic does not publish current pricing. Reported figures have ranged from roughly 300 to 500 US dollars per probe per year including hardware and connectivity.

Galcon: How does it compare with Hunter or Rain Bird?

It competes on battery operation and price rather than ecosystem breadth. The American brands have deeper central control software and broader integration.

Teralytic: How many probes does a field need?

That depends on soil variability. One probe represents one point, so a field with several distinct soil zones needs one per zone to be meaningful.
