I'll address that question.
We've been doing a lot of research for the last three to four years, I'd say, on innovation to improve our recirculation. In general, most of our growers have always recirculated. It allows them to disinfect their water, rebuild up the nutrients they need, and recirculate it back through.
As you indicated, the problem is buildups of sodiums, chlorides, and other components the plants just can't take up. What we're looking at now is a variety of different options, whether those are fluidized bed technology that can remove some of these components, or different versions of our reverse osmosis systems. We're looking at that byproduct you take up and what we can actually do with it. Are there companies that could use it to produce something else? Is it a matter of just disposing of it properly somewhere?
It's still very much in the beginning stages. Our sector has gone over to the Netherlands to try to find out what they are doing, and they are years behind it. I think they have a 2020 deadline to get rid of their issues. We're actually quite leading in this area right now, and we're making a lot of effort trying to find it, but unfortunately, at this stage there's no real solution.
