Wrote this up for a Facebook friend, thought I would share it here.
I use hypo and wash in the field with no electricity. My process is to first hypo clear, then use wash trays for large plates (last season 11x14 and 14x14 inches). I use agitation pumps and sometimes fish tank underwater fan type units to agitate and circulate the water. I wash for 2 hours plus with many water changes. For power I have 3 different type battery power set ups that I usually run dry. This requires you carry a lot of water. I then go to a campsite, recharge my batteries and refill my water. I will try this set up with 24x24 inch plates this year. So this wash process has worked well for me.
The plan is to use this type setup in very remote locations in places like Northern Canada. I will probably be refilling water supplies in streams and using solar at times to recharge batteries.
