I got one from Farm-Tek as a free gift for buying some plastic. It holds about 3 quarts, has a spray nozzle that can be adjusted from a stream to a mist and a release valve. One of the best freebies I've ever received! Mike

Mackissic has sprayers, but they are all larger than 5 gallons....but it is an option.

Your assumptions are correct. The dilution rate is (setting)/gallon. So a setting of 2 ounces will put 2 ounces of your solution into every gallon sprayed. So for me for instance (a random example).. Say I had 7 plants that I want to receive 1 gallon each of fert. MG states a dilution of 1tbs/gal. So I add 7 tbs of MG to the container and fill it with water till it's at the 7 ounce mark. Set it to 1ounce. (I have tested my water pressure and know that 1 gallon is sprayed in 21 seconds)... So now if I water my plants for 21 seconds I know they are getting 1 gallon of water with 1tbs of MG (in the correct dilution)... This thing has been a lifesaver in time. Jay

What is the difference between a regular lavatory faucet (wall mounted) and a heavy duty commercial faucet? Which brands are best? Why do some have the connection between the hot and cold inside the wall, and some outside the wall? Is this just a different look, or something functional? Are the more expensive faucets really much better? I would appreciate any thoughts.
