Hi Prabhi - you're going to love your hozon siphon mixer. Here's what you need to know. I use Miracle Grow and mix up 1 cup of Miracle Grow to 1 gallon of water. I use an empty cat litter jug for the solution.
You'll want to mix it a day before you want to use it as the granules take a while to fully dissolve unless you use very hot water. Mark off a 1 gallon spot on what ever jug you are using. Fill up the jug with water then dump in the 1 cup of Miracle Grow or whatever tablespoon per gallon fertilizer you wish to use. Put the cap on the jug and shake it really well. Shake it again a few hours later and the next morning, shake it again to make sure the granules have dissolved.
You'll also want to use either a fan sprayer or simple watering wand with a shut off valve in the handle - not the trigger type. Do not use a watering wand that has multiple settings for spray type and a hand trigger. The reason being that when you start restricting the flow of water you're going to lose your siphon.
Mine works perfectly on a 100 foot hose.
