Frequently Asked Questions

Q: What is a split-cell root trainer and why is it better?
A: A split-cell root trainer opens like a book, allowing you to see root development without disturbing the plant. This means you can transplant at exactly the right time with zero root damage – resulting in better survival rates and faster establishment.

Q: Why are deep cells better for beans and sweet peas?
A: Beans and sweet peas develop long tap roots early in their growth. Standard shallow trays restrict root growth and cause circling, which stunts the plant. The 12cm deep cells allow roots to grow naturally downward, producing stronger, healthier plants.

Q: Can I use this on a windowsill?
A: Yes – the compact 28-cell design fits neatly on a windowsill or greenhouse bench. The ventilated lid helps maintain humidity during germination while preventing damping off.

Q: How do I clean the propagator between uses?
A: Simply place the cells and base tray in a dishwasher for a thorough clean and sterilisation. This removes any disease or pest residue, keeping your next batch of seedlings healthy.

Q: Is this suitable as a gift for a gardener?
A: Absolutely – it makes an excellent gift for keen gardeners, allotment holders, or anyone who grows their own vegetables. Ideal for birthdays, Christmas, or as part of a gardening gift set.

Q: How many times can this propagator be reused?
A: The injection-moulded cells and base tray are designed for years of repeated use. With proper cleaning between seasons, this propagator will last many growing years.
