jimscott: "I took the smallest measuring spoon we had and filled it with water and counted how many times it took to fill the 1/8 tsp. As far as I can tell, it took 4 scoops worth, meaning that one scoop is 1/64 of a teaspoon.... of liquid measure, not grams of solid measure. I tried looking at conversion charts and there isn't one for teaspoon to grams, of course."
I may be mistaken, but if it took 4 scoops to equal the 1/8 tsp, doesn't that mean each scoop is about 1/32 tsp? and NOT "
1/64 of a teaspoon"?
[1/8 tsp divided by 2 would equal 1/16 tsp; therefore 1/8 tsp divided by 4 would equal 1/32]
As far as the volume (scoops/tsp.) "rough" conversion to weight (grams) is concerned, they likely estimated based on the weight of the powder. That way there was no need to have an expensive/accurate scale to measure out the powder, so they could just estimate that 1 scoop = 1/32 tsp. = .076 gm. & thus it would be accurate enough for most purposes in using the GA-3.
Seeing as it is not some drug being mixed or actual "chemistry experiment", having a rough estimate is accurate enough for most people when applying it to plants/seeds.
Also, looking on the site, it shows the scoop they claim was sent with the GA-3:
"Each order includes the small 1/32 teaspoon plastic scoop pictured above." & also claim
"Water Soluble GA3 Powder 20 is completely water-soluble so you only need to add it to the right amount of water using the small white scoop that is included. Each scoop will hold about 0.076 grams of powder."
Using the tables they provide, you should easily be able to mix up the various concentrations (PPM).
I am not sure what the big mystery is?
