Link4 Greenhouse Controls

Link4 Corporation was founded in 2004 to develop sophisticated but easy to use controller products for the greenhouse industry. The result?

Link4 was founded in Southern California, and created with customer service in mind from the very beginning. The birth of the company was inspired by a discussion about the current state of the greenhouse industry, and its need for environment controllers that are easy to install, program and maintain, yet rich in features. The result was our introduction of products that achieve maximum plant gro

wth while minimizing energy and water consumption. Staffed by designers and engineers, Link4’s vision is to offer the best environmental controls on the market today. This vision is made possible by combining today’s advanced technology with economical production techniques. An intelligent controller system you can choose with confidence, that will help you grow your product, your profits, and your business.

⚠️ STOP wasting time and water! ⚠️

Growers across nurseries, greenhouses, and open fields are switching to automated irrigation systems.

All by smart automation.

Still using an iGrow controller? It might be time to meet the future of growing - the Pearl.

We've worked with growers across North America for years - from small greenhouses to large scale operations - and we've seen how upgrading to Pearl changes everything.

Here's a short teaser of what you'll gain when you make the switch to the pearl:
Hyper-precision crop steering
True modular scalability
Next-gen cloud and remote control

Pearl isn't just the next step after iGrow—it's a leap toward smarter, calmer, more connected growing.

What would you do with the extra time if your greenhouse practically ran itself?

Link in bio to check out the Pearl controller.

Dutch Mill Nursery wanted to save water without losing control.
Now, one Pearl controller manages every zone — seamlessly.

Based in Florida, Dutch Mill grows flowers for Disney World and needed smarter irrigation to qualify for a state grant.

Link4 helped them design a system using one Pearl “brain” to control multiple greenhouses and outdoor ranges via satellite output/input panels — combining scheduled irrigation, soil moisture sensors, and VPD control.

🪴 The result: less water waste, more precision, and easier management.

Did you know? Link4 offers full environmental and irrigation control!

The iGrow 800 from Link4 comes equipped with 8 outputs (expandable to 32) to help you track and record your energy use in real time. Use this to control fans, heaters, vents, irrigation, and shade curtains. Along with your iGrow 800, equip your greenhouse or indoor grow room with our new Sapphire commercial irrigation and mist controller. Link4’s new Sapphire commercial irrigation controller can be programmed for mist, flood, drip or standard irrigation applications for each output.

Growers can achieve complete environmental and irrigation control from Link4 with both the iGrow 800 and Sapphire controller together. These controllers are easily paired on the same Cloud account, allowing users to control both controllers from the same login. By using both of these controllers, growers will be able to easily control the environment and irrigation from one Cloud login.

The iOptimzer is a Variable Frequency controller that is used with our controllers to regulate air flow on fans or the flow rate of a pump.

Running the iOptimizer with fans, will allow you to run all your fans at one time, providing a more uniform air flow pattern compared to traditional methods of operating one fan at one time. The iOptimizer allows you to increase the speed of the fans as the temperature increases, resulting in energy savings and wear and tear on equipment.

Pair the iOptomizer with fans to achieve better airflow patterns throughout your greenhouse, optimizing crop growth and health. Growers can significantly reduce their energy costs for both the startup and operating of fans by running at the optimum energy level of motor. The iOptomizer will help keep your fans running at their optimum speed, resulting in much lower maintenance required for your fans.

For more information on the iOptimizer, visit our website or contact us at [email protected] for more information.
