To increase its capacity for growing rootstock, as well as extend the growing season, Dave Wilson Nursery Inc. is working with Agra Tech, Inc. to design and build a standalone 150,000 sq. ft. greenhouse facility with a wide range of cutting-edge features throughout. For the commercial side of Dave Wilson Nursery, this addition is part of a two-stage expansion plan, with another 75,000-sq. ft. addition anticipated to take place sometime next year.

Mike Farris, Greenhouse Manager at Dave Wilson Nursery Inc., has overseen this construction project and is confident in its successful completion as well as its tremendous benefit to DWN’s production process. The greenhouse expansion was designed and manufactured by Agra Tech, Inc. of Pittsburg, CA and assembled by Ag-Con Construction of San Jose, CA.

“This expansion will facilitate the increased production of almond trees on hybrid rootstock for our commercial market,” Farris said, “which is the driving force behind this recent expansion.”

The expansion not only provides for increased production but does so with great efficiency and labor saving,” Farris said. Phase one’s capacity is 2 million plant starts. Phase two equals that capacity or it will hold 257,000 finished stock in 100mm x 200mm Elle Pots ©.”

Integrated into this greenhouse expansion are a wide range of additional features. According to Farris, these include Agra Tech’s line of mobile trays, under-bench heating, Cherry Creek’s traveling water booms and a secondary overhead heating system, all controlled with a Hortamax control system. The addition of insect screen will facilitate improved plant health and vigor.

Ray Pound is the owner of Ag-Con Construction, a company that has built literally hundreds of greenhouses over the years. Large greenhouse operations call upon Pound frequently to get their greenhouses built on deadline and without complications, because Ag-Con knows how to build even the most complex greenhouses.

Pound has worked on a series of small projects with Dave Wilson Nursery in the past and that’s why he is pleased to be involved in the company’s big project. “The people at Dave Wilson Nursery are great to work with, so when I first found out about this project, we were really excited,” Ray Pound said. “This greenhouse is state-of-the-art throughout and David Wilson Nursery is going to be doing some amazing things in this greenhouse with almond trees. It is going to play an important role within the company, so getting it up-and-running by December is huge.”

With a crew of 11 working day and night to reach the greenhouse’s deadline, Pound is fast tracking everything to make the December date. “I have an excellent crew and by working with Mike Farris, we are really stepping up on this job,” Ray Pound said. “This is a dream project, because it is innovative in many ways and Mike Farris is great to work with. I was involved in several aspects of the greenhouse’s design and offered advice during the planning stage. This is a step into the big-time with all of the companies that worked on this greenhouse, so we’re anxious to be able to see it in action. The design stages on this project started in July of 2015 and on December 1st, we will be up-and-running with this greenhouse and all of its features.”

Micro Paradox Acquires Greenhouse System Designed and Installed by ATI

Randhawa Ventures getting started

Always on the cutting-edge of the commercial greenhouse industry, Agra Tech of Pittsburg, CA and Micro Paradox of Pleasant Grove, CA worked in close conjunction to create a commercial greenhouse system that is unique and unprecedented.

Micro Paradox provides high-quality clonal rootstock to orchard owners and nursery growers, consisting of clonal rootstocks for walnuts, cherries, pistachios and almonds. In addition to providing rootstock, the company can also do custom projects by providing customers with specific types of clonal rootstalks.

Dr. Parm Randhawa

With over 20 years of experience in the seed health industry through CSP Labs, Micro Paradox was founded by Dr. Parm Randhawa in 2010 to provide high superior rootstock to growers worldwide. In addition, he is also the founder and owner of California Seed and Plant Lab, Inc. (CSP Labs), a company that performs seed health testing for the vegetable seed industry. The company was incorporated in 1998 and expanded its services to include seed germination, seed purity, disease diagnosis, resistance screening, hybrid purity, variety fingerprinting and Non-GMO testing.

CSP Labs is located on-site in a separate facility from Micro Paradox but located on the same property. “This close proximity enables us to conduct high quality testing of our products,” Randhawa said. “It’s convenient and useful, because it saves us time and allows us to work without interruption.”

A clonal rootstock is a vegetatively propagated (cloned) rootstock. Rather than using germinated seedling rootstock, nursery owners and growers can carefully select a clonal rootstock of their choice. This clonal rootstock, in turn, can be “budded” to a variety of the grower’s choice, according to www.microparadox.com.

Clonal rootstocks from Micro Paradox are superior over seedling rootstocks, because the latter suffer from genetic variability in that one seedling is different from the other seedling and their perforwalnutProductmance is unreliable. An orchard produced from seedlings may not be productive as some seedlings may lead to inferior trees, Randhawa explained.

“Clonal plants from high-quality trees are genetically alike and therefore perform similar to such characters as vigor, uniformity, budding compatibility, disease resistance and yield,” rootstockPicRandhawa said. “Clones are generally well studied and their characteristics documented by multi-year research before their release to the growers. For example, our walnut clone VX 211 is resistant to nematodes and this resistance lasts for the life time of the tree planted in soils containing nematodes.”

Micro Paradox is well-known for producing some of the best clonal rootstocks in the world. “Several companies can clone walnuts but a very few are good at it,” Parm said. “We are good at it and our reputation lies in “trees with good roots”. Our trees have roots that are at 45 degree from stem, multiple and air pruned to provide an edge when planted in a nursery row or in the orchard.”

“Our process is simple to produce high quality trees,” Randhawa said. “By establishing a contamination-free clone in tissue culture in the lab and increasing cloning in the lab to generate large number of very healthy cuttings, we then root them in the laboratory to a well-rooted plug. Once we’ve established the plug to a well-rooted plant in the greenhouse, we let it grow to a specific size. Then, it’s ready for sale.”

Randhawa was already familiar with Agra Tech, because they had acquired several commercial greenhouses from the company for CSP Labs, but this project for Micro Paradox was a completely different project with different specs and a lot of design required. “This was a truly groundbreaking project and we knew that a lot of the work would have to be custom,” Randhawa said. “By working closely with all of the people at Agra Tech, including John Pound, Ray Pound and Anita Pound and our sales rep, Jim Bergantz, we were able to get this greenhouse and all of its systems up and running by February of this year.”

2015-08 Randhawa 21By designing and building an Agra Tech  Sawtooth framework greenhouse featuring seven separate rooms for different stages of growing, it includes 7 energy curtain systems; connecting doors to each chamber; heating and cooling systems. It also includes a mobile tray system with six transfer carts and a complete railing system to move the trays throughout the entire greenhouse; a Biotherm under bench heating system: a True Leaf Fog system in each of the seven rooms and seven separate center water drip water brooms. It’s a huge project, but after it was completely designed, it took less than six months to make it 100% operable.

Everyone at Micro Paradox is thrilled by the results of their new system and relieved that it went so well. “The customer service provided by Agra Tech has always been exceptional and on this project they really did a spectacular job,” Parm said. “They did their research and came up with solutions that were designed specifically for us. We asked them a ton of questions and they answered all of them promptly and accurately.

“The greenhouse was built by Ag-Con and Ray Pound made it a seamless process, he said. “Every time we needed something–they were right there. It took about six months to get everything up-and-running and today we’re happy to say that our greenhouse is half full already. When we reach our goals, it will be more like three quarters full, which will be full capacity, because, of course, we will always have root stalks being shipped out to our customers.”

Large Companies Tap into Agra Tech’s Knowledge and Cutting-Edge Products

Woodland R & D Facility

Agra Tech, manufacturer of commercial greenhouses and located in Pittsburg, CA, works with small growers all the way to the largest agricultural providers in the world because they value Agra Tech for its extensive experience, innovative spirit and extensive knowledge.

Adam Pound is an Account Manager at Agra Tech and he works with some of these mega-sized companies, so he is aware of what they need and what they expect from any commercial greenhouse company.

Recently, Agra Tech signed a three-year vendor agreement with one of the aforementioned mega-sized R&D customers, a global company with a facility in Woodland, CA, where they breed and grow seeds for vegetables to be sold worldwide. Featuring nine acres containing 60-plus greenhouses, this company is able to simulate all of the climates where they market their seeds.

Because Agra Tech is a highly-respected commercial greenhouse provider, this billion dollar company signed a deal with Agra Tech, but it did not happen overnight. “Once they saw what we could bring to the table, they decided to work with us,” Adam Pound explained. “We started working with them 3 years ago. Initially they were dealing with 23 vendors world-wide and now it is down to 2. After sitting down with them and outlining all of their needs and challenges, we were able to reach an agreement that will take them into their next phase. By integrating some of our patented innovations into their greenhouses, we’ve been able to help them in areas such as employee safety and insect exclusion, among others.”

Exterior Fall Protection Scaffold

The safety innovation that Agra Tech has provided for this large corporation is called the Fall Protection Scaffold System that provides an added level of safety for workers operating both inside and outside the greenhouse. Exceeding OSHA standards, these systems include special engineering of the greenhouse to support the weight and inertia of workers should they fall. By using this scaffolding system, workers will not hit the ground in the event of a fall and the greenhouse will retain its structural integrity.

Interior Trolley Fall Protection

Interior Trolley Fall Protection

There are two different types of scaffolding available by Agra Tech: One for the exterior to maintain the coverings and another for the interior of the greenhouse that runs under the ridge, featuring planks and a trolley that run along the length of the greenhouse. To use it, workers simply snap their safety harnesses the trolley that runs under the ridge to access the roof vent and maintain the screens.

 

The other cutting-edge feature that this large R&D grower wanted to embrace is Agra Tech’s Agri Kool, a positive pressure cooling system designed to prevent insect entry into the greenhouse growing area. Developed in 1992, this system has proven to be superior over negative pressure cooling, the way many greenhouses were using for decades and still do.

“Positive pressure is better at keeping insects out and that’s the bottom line,” Adam Pound said. “This client started using it several years ago and eventually they will be using it in all of their 60 greenhouses. Positive pressure also leads to higher crop yields, temperature uniformity and faster plant growth. Scientists that are developing seeds need uniform temperatures and they also don’t want to have to use pesticides during the growth stage, because they can impede growth. Whenever you spray a pesticide on a plant, it will slow down its growth for days, even weeks. By using our patented positive pressure system, the plants can grow uninterrupted.”

Adam Pound and the Pound family are pleased to be working with all of its customers—from small mom and pop operations all the way to the largest corporations in the world—but signing a contract with a massive R&D company is certainly big news and a very good thing for Agra Tech, Adam Pound said.

“By being associated with a well-known name is good for the company and good for our future,” he said. “We’re big enough to handle any size project and small enough to be responsive. We give them all the best customer service in the industry. By offering our clients more value, we make their decisions a little easier. It’s all about building relationships in any business and this one is surely no exception.”
