You got your humidity to 60% and your plants still look terrible. Here’s why: humidity without temperature is half the story. The number your plants actually respond to is vapour pressure deficit, and until you understand it, you’re fixing a symptom while missing the cause.

Learn indoor plant care basics with a clear framework: light levels (PPFD), potting mix porosity, temperature, humidity, and nutrients. Understand why survival starts under 75 µmol/m²/s, how roots need oxygen, and how mismatches cause stalling, yellowing, and stress long before symptoms appear.

Misting is one of the most common houseplant tips, but it doesn’t solve low humidity. In this guide, we explore why misting fails, the role of transpiration in plant health, and what methods actually work for supporting humidity-sensitive plants indoors.
