The plug trays are designed with large bottom openings and separated cell bases to simplify lifting seedlings for transplanting, while the flat trays have no drainage holes so you can water from below or catch runoff. Lightweight yet sturdy, the trays stack for storage and make moving seedlings between indoors and outdoors quick and tidy.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these trays make transplanting seedlings easier?\u003c\/h3\u003e\n\u003cp\u003eThe plug trays have spacious 0.9\" bottom openings and deeper 3.5\" cell walls, which let you remove an entire plug with minimal root disturbance.
