Galcon irrigation products for nurseries and greenhouses
Galcon, part of the Plasson Group, build controllers from single-valve battery units up to cloud-managed platforms handling 50 mainlines and proportional fertigation. The 8000 series is the one rated for greenhouse misting and livestock-shed cooling, and the S8000 does seconds-based irrigation on minute intervals — which a standard station timer cannot.
Cellular to the GSI cloud; web and app interface; weather-resistant casing
Sizes
Up to 24 valves + master · up to 2 irrigation heads/lines · 2 water meters per head · up to 7 digital and 5 analog inputs
Best for
Their top cloud controller. Up to 10 fertigation programs and 4 fertigation channels per irrigation head with EC/pH control, plus filtration management, flow control and condition programming. Alarm notifications, weather service, history logs, a third-party API and a direct API into Sentek IrriMAX Live for soil-moisture-driven scheduling
Cellular; smartphone and computer control from anywhere
Sizes
Agricultural scale; outdoor enclosure
Best for
Total irrigation and fertigation control with the precision of the AG series and the reach of the cloud platform. The current generation of the GSI line — The GSI-PRO AC build — 24 VAC 50/60 Hz from the grid.
Cellular, no software to install; outdoor waterproof enclosure; connects to terminal units by one-way radio
Sizes
Up to 24 valves + master valve · 8 irrigation programs (series), unlimited starts per day
Best for
Proportional or precision quantity fertigation with an automatic filter-flush program, on quantity, time or weather-based scheduling. Over-the-air software updates, multi-user authorisation hierarchy, real-time alarms by email or push, and detailed irrigation and water-consumption logs. Works with valves already in the ground — The AC build — powered from the electricity grid.
4 or 8 irrigation valves + fertilizer pump and master filter · connects to 4 water meters · 3 conditional inputs · alarm output
Best for
Quantity-based irrigation with flow-rate control and proportional fertigation, sized for small plots, orchards and greenhouse ranges rather than a whole farm. Filter wash program built in. The DC build runs where there is no power at the head — The AC build — grid electricity powered.
Mains powered; rain sensor and dry-contact temperature/humidity sensor inputs
Sizes
8–24 valves · programs split by series A, B, C · irrigation duration 1 minute to 9 hours
Best for
Modular zone control with a time-based fertigation program and an auxiliary program for lighting or any other independent electrical output — useful where the same panel has to run photoperiod lighting as well as water. Weekly or cyclic scheduling from once a day to once a month, a delay function out to 240 days, and seasonal adjustment of run time by percentage
24 V powered; outdoor waterproof enclosure; suits a broad range of valves and solenoids; NC rain sensor input
Sizes
6, 9 or 12 valves, each separately programmable · two valves can irrigate concurrently
Best for
Explicitly rated by Galcon for greenhouse misting and for cooling poultry and cattle sheds — the S8000 model does seconds-based irrigation and minute-interval cycles, which is what misting needs and what a standard station timer cannot do. Multiple cycles per day with a large number of activations
24 V powered, indoor installation; NC rain sensor input; smartphone control on the 8000BT
Sizes
4 or 6 valves, each separately programmable · two valves can irrigate concurrently
Best for
The indoor build of the 8000 — same seconds-based irrigation and high activation counts on the S8000 model, same suitability for greenhouse misting, in a smaller 4 or 6 valve frame for a panel inside the headhouse
Cellular with built-in antenna; DC model on rechargeable lithium with solar or grid charging, AC model mains powered; outdoor waterproof enclosure
Sizes
Up to 24 valves + master valve · 8 irrigation programs (series), unlimited starts per day
Best for
The landscape and turf version of the GSI platform — percentage-based fertigation, water-meter connection, weather-station interface and controllers shown on a map, which matters when one crew looks after many sites. Over-the-air updates and real-time alarms — The AC build — powered from the electricity grid.
Cloud app; drives fertigation machines with EC/pH control and remote terminal units over radio or wireline
Sizes
Up to 50 main irrigation lines · 200 irrigation devices · 100 water meters · up to 40 local fertilizer pumps · up to 7 different fertilizers
Best for
The big-site system — a hierarchical network of up to 50 mainlines rather than a single head. Opens and closes irrigation capacity gradually to stop pressure spikes, and caps flow to the pipework so a bottleneck cannot be exceeded. One water meter can be shared across many valves while each still operates individually, which saves a meter per valve on a large block
Cellular; smartphone and computer control from anywhere
Sizes
Agricultural scale; outdoor enclosure
Best for
Total irrigation and fertigation control with the precision of the AG series and the reach of the cloud platform. The current generation of the GSI line — The GSI-PRO DC build — lithium batteries, or a solar panel with rechargeable batteries.
Cellular, no software to install; outdoor waterproof enclosure; connects to terminal units by one-way radio
Sizes
Up to 24 valves + master valve · 8 irrigation programs (series), unlimited starts per day
Best for
Proportional or precision quantity fertigation with an automatic filter-flush program, on quantity, time or weather-based scheduling. Over-the-air software updates, multi-user authorisation hierarchy, real-time alarms by email or push, and detailed irrigation and water-consumption logs. Works with valves already in the ground — The DC build — lithium battery, rechargeable from a solar panel or from the grid.
4 or 8 irrigation valves + fertilizer pump and master filter · connects to 4 water meters · 3 conditional inputs · alarm output
Best for
Quantity-based irrigation with flow-rate control and proportional fertigation, sized for small plots, orchards and greenhouse ranges rather than a whole farm. Filter wash program built in. The DC build runs where there is no power at the head — The DC build — battery powered, for plots with no electricity at the head.
9 V battery; suits two-wire or three-wire solenoids
Sizes
DC6 up to 6 valves · DC9 up to 9 valves · DC12 up to 12 valves · IP 54
Best for
Battery control for 6 to 12 valves where there is no power — the practical option on an outlying block. Seconds-based irrigation and minute-long cycles on the S model, time-based fertigation on the F11, and smartphone control
9 V battery; dry-contact sensor input to halt irrigation on rain, temperature or humidity
Sizes
1–6 valves · IP 68 — waterproof for outdoor or valve-box installation
Best for
IP 68 means it survives a flooded valve box, which is where these usually die. One to six valves on battery, with seconds-based irrigation and minute-long cycles on the S model and time-based fertigation on the F11
Battery powered with low-battery alarm and manual mechanical opening; rain sensor input; smartphone control on 7101BT
Sizes
Includes a hydraulic valve, ¾" to 2" · model 7001D single line · all 7101 models IP 68
Best for
Controller and valve as one unit for a single line — a run of sprinklers or one long drip lateral — so there is no separate solenoid to wire. IP 68 on the 7101 models for pit installation, and a manual mechanical override to open the valve by hand when needed

The Galcon range published by the manufacturer is larger than what any distributor lists online. If the model, size or spacing you need is not on this page, send the part number or describe the job and we'll quote it. For a full system we would rather see your water source, pressure and crop first: tell us those and we'll help you spec it from the pump to the plant.
