RooTrimmer 3-Inch Square Pots & 18-Cell Seedling Tray Set — 1020 Water-Collection Trays (20x10, 10 Sets)

Smart seed starting made simple

The RooTrimmer kit pairs a 3-inch square pots tray with an 18-cell seedling starter and a generous 1020 base tray to create a clean, contained growing space. Each of the 18 large cells offers ample room for roots and shoots to develop, while the base tray collects runoff for a tidier bench or greenhouse. The no-hole bottom on the base helps you manage moisture and ease handling as you transplant.

Rugged, reusable design that stands up to busy schedules

Constructed from extra thick plastic, these trays resist cracking and bending after repeated use. The sturdy, textured surface feels dependable in hands, giving you a reliable setup whether you tend plants inside a bright room or out on a windy balcony. Designed for multi-season use, they support steady routines without sacrificing performance.

Maximize every inch of your growing area

The system is designed to fit standard 1020 trays, with the 18-cell starter tray measuring about 21.25 inches by 11 inches and a shallow 2.36-inch profile. This space-saving footprint helps you organize multiple seed types side by side while keeping moving parts manageable. The no-hole base tray keeps moisture under control as you water and rotate seedlings.
