Greenhouse Watering Systems: Why Drip Irrigation Beats Sprinklers

The Challenge of Mixed Plant Watering

A 10×7 ft south-facing greenhouse houses diverse plants—ferns, bromeliads, orchids, bougainvillea, succulents, and more—each with vastly different water needs. A single sprinkler or mist system cannot adequately serve all of them.

The Solution: Zoned Drip Irrigation

Convert to a drip system with three separate supply lines, each controlled by its own timer valve:

• Low water: Succulents (aloe, sedum), cacti
• Medium water: Ferns, begonias, impatiens, money tree
• High water: Orchids, bromeliads, bougainvillea

Installation Tips

• Use 1-gallon-per-hour, pressure-compensating drippers for consistency.
• Run spaghetti tubing from each supply line to individual pots; anchor drippers with wire or stones.
• Set timers: orchids may need 2×/week; succulents once every 10–14 days.
• Avoid a single line with variable-output drippers—it's far harder to balance.

Benefits Beyond Watering

Drip irrigation keeps foliage dry (reducing disease), delivers water directly to roots, conserves water, and allows precise control. Your husband's DIY skills make this a perfect weekend project.
