Ive thought about the water use issue with hydro. the only thing Ive come up with, and this is dependent on your space availability, is a system to distill your waste-water. if you had the space you could ,fairly easily, construct a passive solar distiller that would reclaim your h2o and leave the impurities behind. A small submersible heater( think large fish tank heater) could help with the process. The only problem i see, and i haven't run numbers, is you would probably need a containment vessel multiple times the size of the system your running in order to store the waste-water and process enough to not have to add makeup water. It's doable..whether its worth it...IDK.
If you want to go that route for a grower..what you could do is set up a condensate pump from your A/C unit..that is if you are running it this time of year any in cali..also your dehumidifier and collect the water run off that it has distilled kind of out of the air..run the condensate line to a condensate drain pump and run it to a holding barrel or tank and collect it.
You would be surprised at how much condensate water a A/C unit or dehumidifier will put off.Gallons and gallons of it per day.
Another thing about Cali. though.
They seem to be able to shit billion of dollars from a broke economy for a high speed rail system..but dont have the money to put huge underground storage tanks in to collect and store water that would actually be needed and would probably cost far less than a unwanted and unneeded high speed rail system that runs to Fresno California.
The farmers are sweating it right now in cali because the government is going to shut their water off..someone didnt tell Washington that the food produced in cali is needed to feed people with.
Kind of like Ethanol.
Freakin retards running this country..i swear it,Who in the hell votes these people in?
Unbelievable kind of stupid.
You would think if you lived in a desert you would want a water supply.
Hell no ..cant have any of that shit..we need a high speed rail system.
The whole economy of cali needs water.WOW. When you think of cali i know most people think of gays and hippys..well actually cali is one of the largest agri states in the country,
More food comes from that state than anywhere else.
Watch them run out of water cry and wine about it then blame all the neighboring state(who are also short on water)for not giving them their water.
But everyone will pay in the form of higher costs for food for that kind of stupid.
I hope when you get the high speed rail system you tie jerry brown to the front of it along with hollywood wacky doodles and run them at at full speed up and down the rail system at like..300 miles a hour through the middle of a desert waste land in what used to be farm land.
