In our office we have a plant wall (see pictures). The plant wall is located under window skylights, so it receives plenty of sunlight. We've recently noticed a bad smell to the plants and we aren't sure why it's happening. The wall is linked to a filtration and watering system (see pictures) The plants weren't doing well, so they're being watered more frequently now to try and combat that. I've attached some pictures below to show how the plants are fixed in the wall. Each plant is in an individual felt pouch (see pictures). Please let me know what your thoughts are and how we might fix this bad smell.
