Why are there two versions of your website? Some pages have green borders and some have purple?
We created two sites to service the different types of growers we work with – large commercial growers and home growers/hobbyists. You can switch back and forth between the sites by clicking on “Wholesale Site” or “Online Store” in the upper right hand corner.
  • Our wholesale site is designed to be informative and accept quote requests since prices will vary based on the quantity of items, customization for our manufactured trellis items, etc.
  • Our online store has our most popular items available for purchase through the site, but we have many other products available. Contact us at 661.616.6977 and we can talk with you about your specific needs. Our line card is available for download, but even that probably does not have every single item we carry listed so feel free to contact us!
I see some products available for purchase online, but not all.  Why is this?
Only select items are available to purchase online, but we are continuously adding to our online catalog. If you are interested in wholesale pricing, please contact us at 661.616.6977.
