Link4 Greenhouse Controls

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?

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.

You don't learn to swim by reading about water; you have to jump in.

The same goes for growing smarter. Hands-on control, real results — that’s Link4.
