A time-tested, accurate proportioning device designed for small scale growers for the dispensing of fertilizers, insecticides, fungicides and other water soluble chemicals through a hose. The Siphon Mixer proportions at the rate of 1 gallon of concentrate to 16 gallons of water. One gallon of concentrate is dispensed in 3 to 5 minutes. Made of brass.Hozon needs 35 p.s.i. minimum. Use on max. 50’ length of hose.How to prepare a concentrated solution if it isn’t in the chart below: Since the Hozon proportions at 1:16, under normal conditions the concentrated solution should be made at 16 times the recommended rate. Example: If a fertilizer recommendation is 2 TBSP per gallon for hand watering, you would make the solution at a rate 16 time greater than the 2 TBSP rate (i.e. 16 x 2 = 32), so 32 TBSP per gallon would be the concentrated rate. When mixed with water from the hose, the solution will come out the hose end at the recommended rate of 2 TBSP per gallon. Ounces of different types of water-soluble fertilizer needed to make 1 gallon of concentrate for use with Hozon.The Hozon will draw one gallon of concentrate in about five minutes and this will be mixed with approximately 12 to 18 parts of water through the hose, depending on the flow rate. A larger diameter hose, i.e. 5/8” instead of 1/2”, will give a larger flow rate.Excessive back-pressure will cause the siphon to stop drawing. Adjustable nozzles should not be used or should be wide open for best results.
