Featured product


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)
-
Comes ready assembled
