How Necto prevents crop loss and keeps your plants thriving
Prevent Extreme Temperature Stress
Greenhouses can reach lethal temperatures or freeze in minutes if ventilation or heating fails. Necto sends immediate alerts when conditions deviate, letting you intervene before crops suffer wilting, stunted growth, or frost damage.
Humidity and Disease Protection
Improper humidity is the leading cause of mold, mildew, and pests. Remote monitoring helps you detect circulation or irrigation failures early, stabilizing the environment to prevent costly fungal outbreaks and crop degradation.
Power-Outage Awareness
When power fails, fans, heaters, and irrigation stop instantly. Necto alerts you the moment mains power goes out so you can activate backup generators and avoid sudden environmental spikes that could ruin your entire season.

Why Growers Choose Necto?
Don't rely on a spotty greenhouse Wi-Fi signal that often struggles to reach the center of the structure. Necto uses independent cellular connectivity, ensuring you get alerts even if your local internet or router goes down, providing a truly reliable monitoring solution.
Deploy Necto in minutes without specialized tools or complex wiring. The compact, portable design means you can easily move it between different bays, seed starter trays, or temporary cold frames as your growing season evolves.
Unlike smart-home monitors that go dark when the power cuts, Necto has a 3-day battery backup. It continues monitoring and sends alerts the moment power is lost AND when it is restored, keeping you informed through the entire event.

Why Necto?
Reliable temperature and power monitoring with built-in cellular. No WiFi required. Set it up once. Stay informed, every day.
