Description

The Universal Greenhouse Hygrometer/Thermometer gives you real-time humidity and temperature readings in any greenhouse, grow tent, or Ecosphere-style setup. A pressure-fit backing and twist-lock housing let you mount it through almost any panel — just trace the backing, cut a hole, and twist the housing until it locks tight.

Its bright, easy-to-read LCD display keeps temperature and humidity data in view at all times, helping you dial in ideal growing conditions with minimal hassle. It's also a common upgrade for monotub setups, including Grower's Select, Microppose, and Max Yield Bin builds.

Frequently Asked Questions

How do I install this?

Trace the backing onto your panel, cut a hole along the outline, then insert the housing and twist it until it locks tight. No tools beyond a cutting implement are required.

Will this work with my Ecosphere setup?

Yes, it's custom-designed to mount securely on Ecosphere and similar greenhouse setups, and is commonly used as a replacement part.

Does it come with a battery?

Yes, it ships with an LR44 button cell battery included, ready to use.

Can I use this on a monotub instead of a greenhouse panel?

Yes, growers commonly install it on monotub setups as well, including Grower's Select, Microppose, and Max Yield Bin builds, provided there's a panel surface to mount the twist-lock housing through.

How is this different from your monotub hygrometer or mini hygrometer/thermometer?

This gauge mounts through a cut panel hole with a pressure-fit backing and twist-lock housing, making it best suited to greenhouse and Ecosphere-style panels. Our Custom Monotub Hygrometer/Thermometer is instead a push-in design made for monotub side holes, and our Mini Digital Hygrometer/Thermometer is a no-probe unit that clips to the side of any container.
