Sweet Pea Rootrainer Starter Bundle

32 cells. Thoughtfully matched seed. Ready to sow.

This bundle pairs a professional-grade 32-cell Rootrainer with a carefully selected mix of sweet pea varieties — including the highly sought-after King’s Ransom — with seed quantities chosen to suit the tray.

You’ll have 35 seeds in total. Sow one per cell, then double up in a couple of cells if you wish, selecting the strongest seedlings to grow on.

It’s a practical, grower-tested setup — the same Rootrainers I use here at Sweet Pea Gardens to start my own sweet peas each season.

The Rootrainer

These are not lightweight hobby trays. They’ve outlasted every consumer tray I’ve ever tried.

Each set includes one sturdy tray and eight hinged “books” that open easily, allowing you to check root development and transplant with minimal disturbance. The deep cells encourage long, straight root systems and significantly reduce transplant shock.

This is a professional-grade Rootrainer system, made from heavier plastic and designed for repeated use over many seasons.

Includes:

• 1 reusable tray (3.5″ deep)

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

• Comes ready assembled

Product details:

• Tray dimensions: 14.25″ × 8.25″ × 3.5″

• Cell depth: 5″

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

• Material: durable, reusable plastic

• Long-lasting professional quality
