ThinkGrow MODEL-C 18W Single Spectrum Channel Clone LED Bar, 2 Lights Included

Gentle, steady light for early growth, 18W per bar

Young plants and cuttings can suffer when light is too intense or uneven. The ThinkGrow MODEL-C is a single spectrum clone LED bar that delivers stable, gentle output to support seedlings during root development and early leaf growth. It produces 36 umol/s PPF from 18W of input power and has an IP66 rating for damp propagation areas.

This is a compact bar for propagation. It suits hobbyists starting a few trays and growers who need dense, low-profile lighting over cuttings and young plants. Each listing is sold as one unit and includes two MODEL-C bars, a power cord and mounting hardware.
