Yes. I think it's important to realize that there's been a transition in technology as greenhouses have become more sophisticated. As I mentioned in my opening comments, about 90% of our growers recirculate. The process of recirculation means that nutrients in water are delivered to the crop through drip irrigation, which is then captured in a trough, and then that trough is directed to a central location. The water is then treated and recirculated back to the crop, and that happens indefinitely. That's the current state of the industry.
If there becomes a point in time when that material can no longer be recirculated to the crops—if the salts build up, for instance, which tends to be the main reason—then we have developed with our provincial government a tool kit that gives you several options on how to dispose of that material.
Do you want me to go more in depth?
