Part 1: Everything you know about humidity is wrong.

Everything you know about humidity is wrong. I am about to challenge your belief on the subject.
What if I tell you I grow finicky plants like warocqueanum, regale, full moon monstera, and even monstera obliqua in 45-55 humidity?
What if I tell you you can achieve that too?
What if I tell you to increase humidity improperly will do a lot more harm to the plants than good.
This in-depth guide will have three parts. Today I will address the true relationship between humidity and tropical plants. The next two parts will be posted tomorrow and Monday.
Part 1: What does humidity mean for your plants?
Before we jump into humidity, we need to understand plant transpiration. It is the process of water absorbing from the roots, going up through the stems, and evaporating through the leaves. Plants need transpiration to cool down and pump water and minerals to the leaves for photosynthesis. When water evaporates through tiny pores (stomata) on the leaves, Carbon dioxide will get in through the pores, also for photosynthesis. Water transpiration will cause water loss inside the plants. Especially in tropical climates where the temperature and the air circulation are high, the water loss will happen faster. This is the part where high humidity jumps in.
Humidity is the moisture in the air. The more moisture in the air, the less water loss the plants will have and the more water they can absorb through stems, leaves, and aerial roots. High humidity will keep the plant hydrated and slow down the water loss. In the end, what tropical species need is hydration, not high humidity. If you can give them enough hydration, they will not need high humidity to grow. So how can you hydrate the plant without high humidity?
Yes, you are right; water them. Pay attention to your watering and make sure the plants have all the water it needs for the transpiration, then your greeny friends will be happy without 80-90 humidity. Next part I will talk about how to water your plant correctly.
