Link4 Greenhouse Controls

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.

Link4 is excited to see growers and allied manufactures once again. If you have plans on participating at 2021, then stop by and visit us at our booth C3031 October 20-22 in Las Vegas, Nevada.

Link4 continues its innovation with modern technology that meets the needs of current day growers. Come out to our both and we can show you what’s new at Link4.
