Replacement books for the Maxi Rootrainer propagator set. Each book contains four cells, and each frame takes 10 books, so there are 40 growing cells in total. Cells are 20cm deep, and 4.5-5cm wide.
Rootrainers give an excellent start for plants, allowing roots to grow long and straight. The book style allows for easy inspection of growth, and when the time comes to transplant the established plug plant suffers minimal root disturbance.
This is the largest size of the Rootrainer series, and is suitable for large single seeds, such as beans and peas, and cuttings for trees and shrubs. See other sizes, and lots of seed trays, propagators, compost pellets and growing ideas in our dedicated kitchen garden shop.
