As I understand it military bases are implementing the hydro stacker quite a bit.
Also the guy behind it is very interesting and I have learned so much from just talking with him and he is very open to assisting.
He has even developed these gardens in the deserts in the middle east which lead to a design of his tubing that will always keep the water temperature below 80F.
If you are located in or near FL it is absolutely worth the time to visit with them directly, he has excellent free classes and will allow you to roam his farm, etc to figure everything out.
BTW I researched this type of technology for over 2 years before I finally decided on this and spent a lot of money to finally find the right product.
Thank you surfer, I’ve put the address in my computer and will contact him after I talk with some folks here about using that format for a community garden and one for the high school. I really appreciate your helping me (us), because this community really needs something to help some folks. Actually, I’m more interested in beginning a “Farmers Market” with expansion in mind, but to get it, we need to start with the basics..veggies and fruit..then build from there.
