Description
This Rapid Rootrainer propagation set is built for starting seeds and rooting cuttings while helping roots form in a tidy, transplant ready shape. The deep cells keep the compost plug supported and guide roots downward rather than letting them bunch up near the surface. Side channels encourage root branching along the edges of the plug, helping produce a more even root structure before potting on. The result is easier handling at transplant time and more consistent establishment after planting out.
Rapid Rootrainer Propagation System
The rectangular cell format increases contact between the compost and the cell walls. Grooved sides guide roots to grow straight and spread through the plug, helping reduce circling and tangling during the early stages of growth.
Each cell is 8cm deep, making the system suitable for bedding plants, container plants, salad crops and herb propagation. This depth is also commonly chosen for softwood cuttings where a deeper plug helps support rooting before transplanting.
The book style opening design allows each cell to open fully for clean plant removal without pulling on stems or roots. It also makes it easy to check moisture levels and root development during propagation.
Rapid Rootrainer Tray And Lid Pack Contents
The pack includes one holding tray, eight opening books that create 32 individual growing cells, and a clear propagator lid. This layout supports growing several plant types within one unit while keeping plugs organised and easy to handle.
Rapid Rootrainer Dimensions
The complete unit measures 36cm long, 22cm wide and 9cm deep, with a cell depth of 8cm. It is made in dark green plastic containing 70% recycled material and can be recycled.
Frequently Asked Questions
Are Rapid Rootrainers Suitable For Indoor Propagation
They are commonly used indoors in greenhouses, grow houses or other sheltered growing areas, depending on the plant and the conditions required.
Can Rapid Rootrainers Be Used For Herb Propagation
Yes. Herbs such as basil and chives are often started in deeper cells so the root system can develop before potting on or planting out.
Is The Clear Lid Required At All Times
The lid is typically used during early stages to help retain humidity and reduce moisture loss. It can be removed as plants establish and require more airflow.
Can Rapid Rootrainers Be Used For Multiple Growing Cycles
Yes. With cleaning between uses, the tray and cells can be reused across growing seasons.
Is Root Inspection Possible Without Removing Plants
Yes. The opening cell design allows you to view root progress and check compost moisture without disturbing the plant.
