Case Studies

Proptek propagation trays and containers are not just pieces of plastic for growing plants in – they form a system that helps develop superb plants efficiently.

Here are some case studies of nurseries we have worked with to develop a tray or container to help develop an integrated nursery solution.



Mike Coyle | International Forestry Company (IFCO), GA / LA, United States

Working with Proptek has helped us revolutionise how we and the industry grow pine. Proptek’s containers are sturdy and produce incredibly high-quality seedlings with natural roots. The seedlings are so good from these containers that we have been able to significantly extend our growing season. We’ve saved big too on our labor bill, as these trays work so well with our seeding lines and the plants pull so easily too it makes the job of boxing up so straightforward. Containerized pine needs a Proptek container.

Patrick Mobley | Mobley Greenhouse Inc, GA, United States

We have been using Proptek propagation trays for decades now and the plant quality is always second to none. The design helps us produce as many plants per foot as physically possible whilst keeping the quality high, which something that is important to us as we are ourselves strive to produce the best we can. John and the team aren’t just churning out plastic trays – they live and breathe horticulture and have done for years now, so you know you are getting what’s best for the plants. What’s best for the plants is best for us.

Dave Neumann | Dave Wilson Nursery, CA, United States

I use the Proptek 126 cell tray for my 35mm Ellepot rootstock production with great success. Root pruning is a key factor, very little contact with the Ellepot allows air pruning to happen. The trays are also very sturdy with multi-year use.

I also extensively use the 8-cell sleeve and tray system from Proptek. This system is superior to any other tree pot out there. Again, the air root pruning accelerates the growth of the tree without allowing circling roots. When the trees are transplanted in to the ground there is little to no transplant shock allowing the trees to truly take off. Proptek is my go to source for quality growing products.

Jeff Pereira | King City Nursery, Ca., United States

Proptek’s 234 Vegetable tray produces exceptional results – they are so durable and have served us very well for many years now. Our pepper plants grow quick and strong with excellent roots and pull from the cells real easy too. All in all – it’s a great tray that makes our lives here at King City Nursery smooth and efficient.

Jose Lima | Wonderful Citrus, CA., United States

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.

Aaron Dillon, Managing Director | Four Winds Growers, Ca., United States

By using the Proptek pot in tray growing system (both TALL and SHALLOW pot in frame) I am able to get 50% more plants in my greenhouse vs. growing in the conventional #1 gallon, and at least 66% more than conventional #2, or #5 containers. I am getting more units per square foot by using the Proptek growing system.

Additionally the Proptek plants grow faster and produce a better quality root system due to the abundant air pruning achieved with this pot. The air pruning slots also improve aeration and drainage making for a happier, healthier plant. More units and faster turns all equates to more dollars!!

Roger Smith, General Manager | TreeSource Citrus Nursery, Ca., United States

The Tall Pot is a system, not just a container. We designed our 4 acres of facility around the pot and tray and saved thousands of dollars on benching because we only needed rails. The 8 cell tray naturally saves labor by reducing repetitive walking and is conducive to mechanized pot filling and conveyors.

On top of that, the injection molded pots and frames are durable and long lasting. We steam sterilize them and expect at least a 6 year life. The best feature is the root pruning and root architecture caused by the pot. There is absolutely no circling of roots and the mass of roots in the pot is amazing.

Our citrus trees take off and come into production sooner than any other pot used in citrus. Choosing this container was the best decision we ever made.

L E Cooke Company, Ca., United States

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.

In my opinion, Proptek’s 162 injection molded tray is the best reusable watermelon transplant tray on the market.
