Thank you so much Ray. This is the best development in Orchid culture in a
long time.

Most of you are aware of the JavaScript calculator I have on my website
for
determining the concentration of nitrogen, phosphorus, and potassium in
fertilizer solutions. You simply plug in the N, P, and K values from the
label, and the number of teaspoons per gallon you use, and it tells you
the
concentrations in ppm, plus the N, P, & K contributions to the TDS.

After a lot of discussions with the folks at Blackmore (they made the
stuff
for MSU) and Peters, I have concluded that if your fertilizer has a wide
range of minor- and trace elements in it, you can manage your feeding
regimen by simply controlling the nitrogen loading. I have, therefore,
added another calculator to that page which allows one to simply enter the
"N" value from the fertilizer label and the desired nitrogen loading in
ppm,
and it tells you how many teaspoons to add to a gallon of water (and
milliliters per liter).
