I wrote this e-mail a while back, and we have made lots of strides towards the development of this project. What are you working on?
We looked into the use of micro-turbine use, but didn't find that the economics worked out (even with the co-generation) on the scale that we work at (we...
This is a technique that is most typically used in fabric cleaning to allow more water to enter into the pores of the textiles. I know that it also been hyped as a health aid. The importance of reducing the surface tension of water would only be important in agriculture at what is commonly...
There are fairly straightforward methods for calculating the size (and type) pump that is neccessary for a particular hydroponics project. I suggest you check out the catalog from Aquatic Eco-Systems - they have great information on this subject and provide a wide variety of pumps.Though they...
I am currently developing a large scale deep-pool hydroponics facility at an urban site. Deep-pool hydro has also been termed "raft" or "floating" systems. I am curious to exchange information with anyone who might have some experience with this type of design. It was...
I am inclined to use a waterproof concrete design rather than liners for a number of reasons that have to do with the detailed design of the hydroponics system itself. I have been looking into a line of waterproofing materials produced by Xypex. The literature claims self-repair of hair line...

Thank you for that information. I hadn't considered the strength the side beams will be adding to the structure, but it makes great sense.
There are areas on the old slab where settlememt has taken place, where chunks are missing and where pieces of old foundation walls have been left in...
I consult on intensive and sustainable cropping systems that includes hydroponics. I have been working with an urban farm for over a year now and we have found that hydroponics is one of the technical solutions that will allow brownfields to be redeveloped as agricultural facilities. When...
I am an agricultural engineer working on a development in a brownfield site in Philadelphia. The project is the construction of a 10,000 square foot hydroponics facility that will include several 100'x 20' low-walled reservoirs. The site is over 75 years old, the original slab is still present...
