Sustainable Agriculture

Practical growing systems, built for how you actually grow

Alternative Solutions AG began as a working demonstration and research farm in Antigua, combining hydroponic technology with traditional farming. We design and build hydroponic systems, propagation setups, composting solutions and greenhouse installations, working through the whole system with our customers rather than simply supplying equipment.

Community Growing

Grow Together. Live More Resiliently.

Alternative Solutions AG supports practical food-growing systems, propagation, water conservation, and community resilience. From starting plants indoors to growing food outdoors, we help people build the skills and systems needed to become more self-reliant.

Hydroponic System Design

Systems designed around your space, crops and goals

Alternative Solutions designs practical indoor and outdoor hydroponic systems for homes, farms, schools, community programs, and commercial growers. Each system is planned around the available space, crops, water supply, power requirements, production goals, and future expansion needs.

Plant Cloning & Propagation

Controlled environments for starting and rooting plants

We help create controlled environments for plant cloning, seed starting, and early-stage propagation. Solutions may include propagation trays, lighting, humidity management, ventilation, irrigation, monitoring, and grow-space organization.

Rooted cuttings growing in small cups outdoors — Early-stage cuttings, potted and hardening off outdoors.

Seedling trays of okra, beans and other starts on an outdoor propagation table overlooking the coast — Seed-starting trays on an outdoor propagation table.

Aerated Composting Solutions

Turning organic material into a usable soil amendment

We develop practical composting solutions for farms, gardens, and community agriculture programs. This aerated static composting system was developed through collaboration with community gardens to improve airflow, support decomposition, reduce manual handling, and turn organic material into a useful soil amendment.

Poured concrete foundation slab for a composting bin structure at a community garden — Step 1: a poured concrete pad forms the bin's foundation.

Cedar plank walls being framed into a two-bay composting bin on the concrete pad — Step 2: cedar bin walls, framed on site.

PVC pipe fittings laid out to build an aeration manifold for the composting bin — Step 3: an aeration pipe manifold, built and fitted to the bin.

Finished multi-bay composting bins with hinged mesh lids at a community garden — The finished bins, with hinged screened lids for pest control and airflow.

Greenhouse Sourcing & Importing

Sourcing the right structure for your site

We source and import greenhouse structures for residential, community, and commercial agriculture projects. Greenhouse selection is based on the site, growing area, crop requirements, ventilation, weather exposure, installation conditions, and budget.

Note: Sourcing and installation scope vary by project. Confirm what's included, sourcing only or sourcing plus installation, when you request a quote.

Agriculture Planning & System Integration

How everything works together

A productive growing system is more than a collection of equipment. We help customers consider how water storage, irrigation, energy, ventilation, temperature management, monitoring, and operating procedures work together as one system.

Our Roots

Where it started

Alternative Solutions AG was founded to help Antigua build a more resilient, self-sufficient food system, testing and adapting soil, container, hydroponic and aquaculture systems on a working demonstration site, and translating them into smaller systems for homes, schools and communities. Today that same resilience thinking extends to water and energy. Read more about us →
