To maintain tightly controlled relative humidity in an indoor grow, Quest Climate explains why a layered RH control strategy—using multiple dehumidification tools that work in sync rather than a single oversized unit—helps manage rapid humidity swings, protect crop quality, and boost yields throughout the grow cycle.

Endless Cultivation routinely pulls 100–150 grams per square foot, doubling or tripling industry averages.

Commercial growers use basalt (or basaltic) mineral wool in their hydroponic growrooms, and you should consider using it, too. What is mineral wool? Also known…

Plants grown in a hydroponic system need dissolved oxygen (DO) in their water to thrive and provide optimal yields; in hydroponic systems, most oxygen absorbed…

There’s a lot to concentrate on if you’re to keep your plants healthy and reap the best harvests: The right light, proper humidity, correct temperatures…

There are three ways to measure moisture in a grow. Relative humidity (%RH), grains per pound, and now, dew point temperature. What is dew point…

As we discussed last time, relative humidity (%RH) is a way to measure moisture in your grow room’s air. Today, we’ll talk about “grains per…
