Answer a few questions about your grow and we'll recommend the exact LINKS equipment you need — with the option to email it to yourself or add everything to your cart.
Are you controlling lighting?
LINKS can dim and schedule your fixtures automatically.
What brand and type of lights?
Select every type you have and enter the number of zones for each. A "zone" is a group of lights controlled together.
Climate control
Select everything you want to automate and tell us how many of each. A climaLINK sensor is added automatically for each climate zone.
Irrigation
Automated valve control for precise watering and crop steering.
Each valveLINK handles 8 zones. We'll add more as needed.
Substrate sensing
terraLINK sensors track moisture (VWC), EC, and temperature in the root zone — essential for crop steering.
One terraLINK per zone. canopyLINK holds up to 8 sensors total.
Nutrient mixing & dosing
Optional: automate nutrient tanks and feed recipes.
