I took a lot of precautions because my last run got eaten by slugs (probably because of the top dressing (leaves) you can see in the very 1st image). Besides that, I just focused on a stable and humid environment for the 1st Week. A very exciting aspect is that I noticed a variegation on the Mimosa Cake Auto right from the start!
Notice how there are random little plants coming up, as well as mycelium, moss, et cetera? The system already starts to stabilize itself and creates a breeding ground for all sorts of organisms that - in the end - will benefit the symbiosis and longevity of said system.
About this grow
01: Mimosa Cake had water contact on 01.12.25, Gorilla Z on 04.12.25. Mimosa Cake broke through the soil on 04.12.25, Gorilla Z on 07.12.25. The documentation starts at 04.12.25 (so you have to add about 3 days to the Mimosa Cake to get the real age including the germination).
02: I used the nutrients tab to show the light intensity (ml/l) (I will rarely fertilize because of the living soil).
03: This is a low-noise, low-budget grow (less than €200 acquisitional cost, less than €20 per month, less than 30 dB). I don't use an air filter and try to minimize every use of electricity (the system can't draw more than 105 W). I will try to add an Info tab as soon as I've figured out how. 😅
04: This works, because the goal is to learn how living soil (and nature really) works - healthy plants are just a side effect. To this end, I am intensively engaged with the biological functioning of plants (which is also an important part of my profession as a product designer focused on biomimicry). I take what is known, question it, compare it with knowledge from a wide range of disciplines, and try to develop a system that is as durable and as efficient as possible.
05: So, yes, I could use higher PPFD + increase the substrate temperature to 26°C, but that would be inefficient (in my setup) because none of the values are in a critical range right now and stay like that naturally because of the ambient enviroment (just so that you understand my reasoning for this experiment).
