Field Notes
Humidity Is Only Half a Number
60% humidity can describe very different growing conditions. Temperature—and the leaf itself—would like a word.
Swirskii Needs More Than a Warm Room
How warmth, drying air, and sachet placement interact, and why to measure the environment near the foliage.
Your Grow Light Isn't Killing Your Predatory Mites. Your Humidity Might Be.
UV gets all the attention, but it's rarely the problem under standard LEDs. The variables that actually determine whether predatory mites thrive in a lit grow space are humidity, heat, and photoperiod — and all three are fixable once you know what to look for.
The Hidden Weather That Shapes Plant and Predator Life
Invisible weather shapes every growing space. Warm air pools under lights, cool air settles near the floor, and in between, tiny predators decide where they’ll thrive. Learn how microclimates influence the balance between plants, pests, and the mites that keep them in check.
