"As a small grower with several years of experience in field production and no greenhouse experience, I am now the owner of a new greenhouse, 3400 Sq. ft., and am devoting my spare time to learning hydroponics production. When I was looking to buy a controller, I found a lot to choose from and a lot to learn. Between the very complex expensive controllers and the less expensive basic models, is the iGrow.  Truly in a class of its own, it offers sophisticated functionality, dependability and ease of use at a price a beginner can afford. Set up went flawlessly. The user manual is excellent: concise and easy to understand with lots of display screenshots. I do not yet have the software which provides even more flexibility and lots of charting capabilities. For the few times I have had a question, Link4 customer support has been only a phone call or email away. Response time is quick and the tech team is knowledgeable, friendly and always helpful. Link4 makes a number of controllers models. Anyone considering a greenhouse controller, for small or large operations, should take a look at Link4 products."
