Consider climate, plant species, maintenance, and lifecycle costs. Plant-based media often excel at moisture regulation and root establishment, while recycled cores can deliver long life and lower virgin material use. A blended approach can also work, combining quick establishment with durability.
Are biodegradable media suitable for all installations?
Biodegradable media work well for temporary or seasonal walls and spaces that will be refreshed regularly. For long-term installations, pair biodegradable components with durable cores and plan regular refresh cycles to maintain plant health and appearance.
What about costs and savings?
Calculate upfront costs per square meter and add projected maintenance, replacement, and disposal costs over 5–10 years. Substrates with longer lifespans and easier maintenance typically save money in the long run, even if the initial price is higher.
Can I mix substrate types?
Yes—blending plant-based media with recycled cores can combine rapid establishment with durability. Test blends in a pilot zone to optimize performance before broad rollout.
