I would mix your spray bottle with the same ratio you’re going to get when down streaming and run another test. You’re talking 50% compared to a 10% mixture. You will then know if you need a backup plan. Check out Patriotspwashing and his pure water system using a battery backpack sprayer and water fed pole. You wouldn’t even have to use a battery backpack but rather a cheap pump up sprayer. You’d be able to hit it with any strength EBC you want.
If you scroll down to the 26 post he gives a parts list. Actually, you could probably throw something cheap together without ordering anything. Just get a pump up sprayer and 30’ of 3/16" hose or whatever length and size you need. Cut the pump up sprayer hose, connect the two hoses with a couple hose barbs and zip tie the wand and hose to a pole. Get everything ready, zip tie or tape the wand trigger, and start spraying. You could even throw together a cheap 12v.
