Q 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 planted it will have a 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 grow around the container in a restricted pattern which results in twists and strangulation. 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.

Q 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, as they remain impervious to water, fertilizer and roots, unlike Styrofoam trays. Added to this, plants pull more easily than from Styrofoam trays due to the smooth impervious wall with less plant loss at planting time.

Q How much maintenance is involved with Proptek trays?


Proptek trays are easy to clean and sterilize as only surface sterilization is required so are much more hygienic with no carry over of problems to the next crop.

Q What do Proptek’s tray codes mean?


All our tray codes have a maximum of seven digits. The logic of these codes is as follows;

- The first three digits describe the number of cells in the tray.

- The fourth digit mainly describes whether the tray is a stacking or nesting tray, i.e. "S" for stacking and "N" for nesting.

- The fifth and sixth digit refer to the dimensions of the tray, e.g. "26" refers to the length of the tray at 26 inches, "67" refers to the length of the tray at 67 cms, "10" refers to the tray width of a bedding plant tray at 10 inches and "20" refers to the tray length of a bedding tray at 20 inches.

- The seventh digit refers to additional options on that tray such as, "F" for feet, "N" for no feet or other more specialized codes to represent the place of manufacture.

Q 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, but 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!

Q 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 so they are cheaper in cash terms than other types of tray.

Q 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.

To find out more please contact us.

Q How adaptable are the trays with my business?


Proptek trays are likely to be compatible with most automatic transplanting machines due to our longstanding understanding of the industry.

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