Frequently Asked Questions
What is Air Pruning?
Air Pruning is a system which forces root tips out of a container into dry air which kills the root tip. This encourages the growth of secondary roots and means that the plant constantly produces new and healthy branching roots. This means that once the plant is transplanted it will have an exceptional root system and so will take up water and nutrients more efficiently, resulting in a healthier plant.
Where roots are not air pruned they will continue to circle around the container in a restricted pattern which results in twists and strangulation. This is called “Root Circling” or “Root Girdling” and is very bad indeed. Once the plant is installed, it is unlikely to establish a normal root structure and after planting will have a reduced uptake of water and nutrients. Read more about Air Pruning on our product support page.
What are the benefits of using injection molded plastic trays and containers over Styrofoam or polystyrene?
Our injection molded plastic trays and containers will produce better quality plants with more uniform plant growth. This is because they remain impervious to water, fertilizer and roots, unlike Styrofoam trays. Added to this, plants pull more easily than from Styrofoam trays due to their smooth impervious walls. This means less plant loss at transplanting time.

How much maintenance is involved with Proptek trays?
Proptek trays are easy to clean and sterilize as only surface sterilization is required. This means they are much more hygienic with no carry over of problems to the next crop.

How do Proptek manage to increase the number of plants per tray without compromising on plant quality?
Proptek’s vegetable trays do not require a large outer rim which means that it is possible to fit in more cells per tray. Styrofoam trays have large outer rims due to the nature of the material that they are made from, while thermoformed trays require the rim to stop them from bending and to add rigidity.
As Proptek trays do not require a rim we are able to produce them with more cells per tray. However, we are also able to space them out enough to ensure that plant quality is not compromised. Therefore you will be able to produce more cells per tray, which means more plants per greenhouse and more profit for you!

What are the commercial benefits that I might see from Proptek trays?
Our products can be more profitable than Styrofoam trays as you have more plants per tray but of better quality with a lower unit cost price. Furthermore, Proptek’s trays typically last many times longer than a Sytrofoam or thermoformed plastic tray.
Additionally, finance leases may be available in some areas to finance these trays. This can mean they are cheaper in cash terms than other types of tray.

What are the environmental or ecological benefits of Proptek trays?
All our products are made from recycled plastics and in such a way that there is minimal impact on the environment.
Because our propagation trays last many years, there is reduced waste and impact on the environment compared to Styrofoam products. At the end of their life span, our products can be recycled once again. We even have some trays made in 1987 that are still in use today!
We also manufacture our products as local to customers as possible, resulting in shorter lead times, lower shipping costs and a reduced impact on the environment.

How adaptable are the trays with my business?

Trays can also be molded with your company name and address for identification and promotion.
