Details & Features

This one piece 45 cell tray is equivalent to the traditional 2.25” “rose pot” in spacing terms, but with extra features to ensure excellent plants and efficient operations.

The 45 tray is perfect for use in the woody ornamental and nursery stock propagation market, though is suitable for a very wide variety of plants. This is also a good size container for the propagation of hemp seedlings for transplanting to the field or greenhouse.

The open design allows excellent drainage and aeration, but the solid outer wall prevents cross-rooting between trays.

Root circling is eliminated due to Proptek’s specialist root training ribs and air root pruning windows. Due to the specially chosen cell angle, exceptional roots and tough injection molded design, plants pull exceptionally easily.

The cells also feature a cross-shaped base hole to allow for extraction from the base by pushing up in corners where roots are concentrated – prefect for cost-saving automation systems.

As with all Proptek trays and containers, the 45 is injection molded for long life, easy handling and trouble-free mechanization.

Please Note…

1 Full truck loads can fit more trays per pallet as a dedicated full size 53ft lorry is used for delivery. For partial truck loads, we cannot guarantee the height of the lorry, so pallets must fit into all commercial freight vehicles. If arranging your own transport, please advise us at the earliest opportunity on the internal height of your vehicle.

2 Trays are stacked loose or partly loose to get the maximum number of trays per container. This will result in lower unit shipping cost but also more labor to unload

All statistics and measurements may vary so please check before purchasing, if critical, or ask for sample.

I have used the 8 deep pot in frames since 2010 when I had the opportunity to closely participate in its design. The creation of this pot in frame marks a pivoting moment in the conception of modern professional citrus nurseries around the world. Technically speaking the pots are ideal for root development with adequate depth associated with internal ridges which direct the roots down and windows that cause air pruning enabling even more root mass to develop. The frame holding 8 pots make it an easy transition to automation and conveyance which are key features in any professional nursery in the new era of high labour cost. In my point of view, the question of which container to use in a professional citrus nursery has been answered by Proptek and its 8 cell deep pot in frame.

I think they [Proptek’s propogation containers] are one of the best root pruning pots out there.  For one thing they are in a 10×20″ format which allows us to be able to maximize our bench space, where other types of air pruning pots leave a lot of open bench space.

I also like the way the plant is easily pulled from the pot and then easily put it back into the pot when checking the roots.  I like the injection mold type of pot instead of cheaper thermoformed pots.  They last much longer and are definitely worth the price point.  I think these pots should be more widely used in the industry, therefore making better roots on plants for the whole industry.

Simply the best pots, producing the best trees, with the best root structure in the world.
