Dew Collection Starter System — Jardin Healing Garden

Harvest atmospheric moisture every morning. No tap. No pump. No power.

In South Louisiana, pre-dawn humidity averages 93% in summer months. The Dew Collection Starter System is a passive atmospheric water harvesting installation designed for healing herb gardens, medicinal plant beds, and intentional land stewardship. Built from PVC frames and dark shade cloth mesh, this entry-level system collects morning dew along the back edge of your garden bed and delivers it directly to your plant roots via gravity-fed soaker hose — before you wake up.

What Is Atmospheric Water Harvesting?

Atmospheric water harvesting (AWH) is the process of collecting water vapor and dew directly from humid air using mesh or fog collection surfaces. In high-humidity climates like the Gulf Coast and Southeast United States, passive dew collection systems can supplement or replace conventional irrigation during the growing season. No electricity. No moving parts. No municipal water required.

System Components

• PVC frame panels — 18” wide × 24” tall, spaced every 9 feet along the back edge of your garden bed
• Double-layer dark raschel shade mesh — pulled taut within each frame for maximum dew capture surface area
• PVC collection channel — runs the full length of the bed, gravity-sloped from west to east
• Food-grade rain barrel — partially buried at the east end, receives all collected water
• Soaker hose distribution line — exits the barrel base and runs the full bed length along the soil
• On-site design consultation and installation guidance — included

How It Works

Panels are mounted along the back edge of the garden bed, angled 10–15 degrees off vertical toward open sky. As humid night air contacts the mesh surface, water vapor condenses into droplets. Droplets coalesce and run downward into the collection channel. The channel carries water by gravity into the barrel. The soaker hose delivers that water slowly and directly to root zones — zero runoff, zero waste.

Climate Performance

Designed for Gulf Coast and Southeast U.S. conditions. Average pre-dawn relative humidity in South Louisiana: 78–93% from May through September. At 93% humidity, passive mesh collection systems can yield meaningful supplemental irrigation volume nightly — enough to maintain soil moisture in a 55-foot medicinal herb bed without any additional water source.

Best Applications

• Healing herb gardens and medicinal plant beds
• Apothecary gardens and botanical installations
• North-facing or open-sky garden exposures
• Homesteads and land stewardship properties
• Educational and demonstration gardens
• Clients beginning their atmospheric water harvesting journey

About Jardin — The Healing Garden

Jardin is the garden consulting and design service of Big Mamou Enterprises, rooted in South Louisiana’s Cadien land and healing plant traditions. Every system we design is functional, site-specific, and built to work with the climate — not against it. We design for the land. The land does the rest.
