Here's what I believe is the easiest way to use megacrop.
Equipment:
1. 1 gallon of known ppm water in a jug. Those distilled water grocery store jugs are perfect.
2. 0.1 gram accuracy scale.
3. Small container with a lid to hold a hundred grams or so MC.
4. Simple calculator to compute amount of MC needed.
5. Measuring spoon(s).
Preliminary, one-time measurements:
1. Add exactly 1.0 g MC to the 1 gal water, and mix well.
2. Measure MC ppm for future reference, by taking ppm with MC minus ppm of water. For me, it came out to be around 120 ppm.
Feeding:
1. Use the calculator to determine how many grams of megacrop are needed to make a known amount of the desired ppm nutrient.
For example, if we wanted 1/2 gal of 500 ppm nute, which is 250 ppm MC, then we'd use MC = (250 ppm)*(1 g MC)/(120 ppm) = 2.1 g, or putting it more simply, divide the desired ppm by 120.
3. Put the jar of MC on the scale, zero the scale, and then remove enough MC with a measuring spoon until the scale reads (negative number) the amount that we want to use. In this example that's -2.1 g.
4. Mix and use.
I'm still using the old version, and completed a successful DWC grow using only MC and nothing else whatsoever, except pH Up/Dn and clorox.
My only complaint is that the autos got much bigger than expected, and I should've topped them.
I never went above 450 ppm, then down to about 250 ppm near harvest, and the plants had no deficiencies.
