Rootrainers Professional Seed Starting Tray

These are the same Rootrainers I use here at Sweet Pea Gardens. I rely on them season after season to start my sweet peas seeds — and they’ve outlasted every hobby tray I’ve ever tried.

Each set includes one sturdy tray and eight hinged books that open like a little greenhouse journal, revealing strong roots. The design encourages deep root systems, minimizes shock at transplanting, and lasts for years.

This is a professional-grade Rootrainer system — built to withstand repeated use, with heavier plastic and a sturdier design than typical consumer trays.

Includes:

• 1 reusable tray (3.5″ deep)

• 8 “books” (4 cells per book = 32 cells total)
  

• Flat-packed for safe, low-cost shipping

Product Details:

• Tray depth: 3.5″ (approx. 8.9 cm)

• Cells per book: 4 × 8 books (32 cells total)

• Material: durable, reusable plastic
