Light conditions
Read more: Light conditionsThis post is last of a three-part series discussing water conditions, nutrient conditions, and light conditions in hermetospheres. When I started my first hermetospheres, I intuitively felt that the place chosen within my apartment did not provide enough natural light for plant growth. I therefore installed LED grow lights, first one, then a second. Now,…

Nutrient conditions
Read more: Nutrient conditionsThis post is part two of a three-part series discussing water conditions, nutrient conditions, and light conditions in hermetospheres. In a closed system of plant life, water, carbon and nutrients are subject to cycles. In the case of nutrients, dying plant tissue is beeing decomposed by bacteria and fungi, and the nutrients it contains are…

Water conditions
Read more: Water conditionsWith certain limitations, we consider hermetospheres as closed systems. To get closer to the goal of long-term stability of this system, it is important to understand the conditions and processes within the system. They depend on the initial situation and on external factors such as temperature or light. With this in mind, this article begins a…

Acclimation (1): Ficus punctata
Read more: Acclimation (1): Ficus punctataClosed glass containers inevitably create extreme conditions for plant growth. This is especially the case for relative humidity, which can be assumed to be close to 100% at all times. Most tropical plants can deal with this, and hardly ever I could observe obvious changes from “normal” greenhouse conditions, where my plants usually come from,…
