Rootrainers help plants develop more quickly, by allowing roots to grow straight and long. Being able to open up the books, progress of growth can be inspected, and when time comes to transplant the disturbance to the vital root system is minimal.
These Deep Rootrainer sets comprise 8 books, one holding tray and a clear plastic lid. Each book has 4 cells, so there are 32 growing cells in total. Each cell is 12cm deep.
Especially good for runner beans, broad beans, sweetcorn, peas, french beans, sunflowers, wallflowers, sweet peas and strawberries.
