Seedling Heat MatsOUR TAKE
VIVOSUN 10 × 20.75-inch seedling heat mats, two pack
Two waterproof seedling heat mats for an indoor propagation setup.
A pair of mats is useful when spring sowing grows beyond a single tray. Keep the bench tidy, run the cables away from water and check the growing temperature under each tray. Move sprouted seedlings to the conditions their variety needs.
