Why does a low flow weed sprayer take forever to use?
Low-flow sprayers require crawling at speeds around 0.75 mph to apply the correct chemical concentration, turning an 8,000 square foot yard into a grueling 40-minute ordeal. Trying to speed up this painfully slow pace leads to uneven coverage and patchy, discolored lawns that take weeks to recover.

“I have Spraymate Tornado (0.2GPM) and T-Zone SE. It says to mix 1.5oz per Gal per 1000 ft^2. At a 3ft wide spray that equates to 0.75 mph walking speed. Average walking speed is 3-4 mph, so this would be a slow crawl and at an 8000 ft^2 yard, it would be 40 minutes of spraying.”source ↗
“i did something similar last summer with my backpack sprayer, tried to rush through it and ended up with a checkerboard lawn for like 3 weeks, took forever to even out”source ↗
