About Link4 Greenhouse Controls

Link4 Greenhouse Controls manufactures software and environmental controls for growers wanting to optimize their greenhouse production and reduce operating costs. We enable our customers to manage every aspect of their greenhouse from the palm of their hand, using state-of-the-art controls that relay greenhouse data to the Cloud where it is accessible on any Internet-connected device. With a wealth of data at their fingertips, Link4’s customers are able to grow bigger, more vibrant crops under repeatable processes. Link4 protects their crop investment with text alerts sent straight to their phone identifying a variety of threats, including equipment failure and environmental abnormalities.

Link4’s greenhouse controls are designed to meet each individual grower’s needs, from an at-home hobbyist to large industrial grow houses, indoors and out. Each product comes with our tenacious customer support that begins with a consultation on your project to ensure they are getting the right controls, built to suit their needs.
