Rootrainer design
The hinged book allows for easy root inspection, moisture checks and seedling removal. The closed books fit snugly together and several can sit side by side inside a clever little tray which holds them securely. Each cell contains vertical ridges which encourage roots not to spiral. Instead they form a good fibrous downward growing root system, whilst protected in the rootrainer prior to planting out. Upon reaching the aeration hole at the bottom, they are ‘air pruned’. This basically means that the roots stop growing downwards when they meet air. As a result the plant produces more lateral roots inside the cell. If they were not air pruned, they would continue growing downward and along the bench, floor or wherever they were being grown. This would make it very difficult to remove from the cell.
Initially, they are a little expensive (as many patented products are) and a bit fiddly to clean. However, when you consider that I have had some rootrainers for 6 years, then the price pales into insignificance. They are so versatile, from acorns to peas, runner beans to onions all of which can be successfully grown in Rootrainers. They do represent excellent value for money.
