Guttation does seem to happen in monstera more than other plants, but maybe I just notice them more because of the huge leaves. transport-in-plants. The white deposits occur because guttation droplets contain some amount of mineral salts, sugars, and amino acids. The transpired water is pure. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution. Water in the soil is absorbed by the roots of vascular plants by osmosis when the water potential in the roots is lower than the water potential in the soil. Plants also use stomata for photosynthesis, and since photosynthesis does not occur at night (after all, it cannot happen without the sun), the stomata close.
