Reka, I use a little less than a teaspoon in the 1 quart spray bottle. I
have never dipped & soaked the entire plant. I have a couple of plants
that I am going to experiment on.
I browsed through this webpage & noticed that just for the different types
of orchids they call for different measures? Quite an in depth site.

Okay, so we are talking about 2tsp./gallon 20%, 1 tsp./5 liters 50%.

Do you guys use less than 2 tsp. gallon?
