Q.cat safe plant for a tiny house
I live in a tiny house on wheels and want to find the ideal air purifying plant that won’t require humidity. Any tiny house has to be careful of humidity in the winter as mold is quick to grow. Recommendations?
In the past snake plants created too much humidity and therefore mold.
How about spider plant?

Snake plants are actually one of the drier species. They should not cause too much of a humidity issue unless they get overwatered. In fact, that would be a very highly recommended species for that application.
There are xeriscape plants that will tolerate even drier conditions that you might be interested in. Most are very easy to care for, but maybe not the most efficient for purifying air. Generally the more broad the leaf, the better it is at purification.
