What is the amount of fertilizer needed for one gallon of concentrated
solution in ounces? I am using the Hozon injector and Peters 30-10-10
Orchid Special.

Hozons are supposed to work at 16:1, so once you've decided how much of that
fertilizer you want in your final solution, you simply mix 16X that in your
concentrate.

You can use my fertilizer calculator to determine the amount to use to get
the final concentration you want. Personally I'd recommend about 100-150
ppm N.

On a mass basis, the fertilizer is 30 weight percent nitrogen. Shooting for
125 ppm N concentration (0.0125 weight percent), you'd want the concentrate
to be 0.0125 x 16 = 0.2% fertilizer powder, by weight. With water coming in
at 8.337#/gal, then you'd be in the ballpark with 0.002 x 8.337# x 16#/oz =
0.267 ounces of fertilizer.

Alternately, for a 30-10-10, 1/3 teaspoon per gallon will give about 125
ppm, so to make up a gallon of that concentrate, you'd need 1/3 x 16 = 5.33
teaspoons.

I wouldn't worry about being too exact. Siphon-type mixers are not overly
accurate or repeatable, so variations in your actual application will
outweigh any small discrepancy in the concentrate.
