Product Information

Full details

The Deep Rootrainer Tray System is an essential propagation tool for gardeners and horticulturists looking to grow plants with deep, vigorous root systems such as sweet peas, beans, and strawberries. By utilizing a unique book-style cell design and air-pruning technology, these trays promote healthy, non-tangled root development and allow for transplanting without disturbing the root ball. While they offer professional-grade root management, users should note that the assembly requires careful alignment of the book-style cells within the frame to ensure they lock securely before planting.

Extended Product Information

FAQs

Can I use these for indoor seed starting?

Yes, they are excellent for indoor use provided you use a drip tray underneath the frame to prevent water from leaking onto surfaces.

What type of soil mix should I use?

A standard, fine-textured seed starting mix that offers good drainage is recommended to ensure roots can easily navigate the grooved channels.

Are the lids included for every unit?

Yes, each pack includes lids to help retain moisture and warmth during the crucial germination phase.

Are replacement cells available?

The system is designed for long-term durability; however, users should handle the plastic clips carefully to maintain the integrity of the closing mechanism.

How deep are the cells?

Each individual cell measures 11cm in depth, providing ample room for deep root growth.

Troubleshooting

Cells falling out of the frame

Ensure all cell pairs are securely snapped together and properly seated in the frame channels before filling with soil.

Difficulty opening the cells for transplanting

Check that the soil is not overly compacted at the seams. A gentle tap on the side of the tray can loosen the root ball before opening.

Setup, Compatibility & Care

To set up your Rootrainers, start by snapping the book-style cells together and placing them firmly into the provided frame. Ensure that the drainage and air-pruning holes are clear and unobstructed before filling with media. Regarding compatibility, these trays are suitable for any greenhouse, conservatory, or windowsill environment. To care for your system, wash the trays with warm, soapy water after each season to remove soil residue and sanitize against potential pathogens. Store them in a dry, shaded area to prevent plastic degradation from UV exposure over time.
