Hello Ray!

What about the S/H culture?

How much Dyna Grow shold I put in a gallon of tap water ?
On the instruction sheet, you suggested 1/2 teaspoon of DynaGrow and 1/4
teaspoon of Protekt.

Now, since you believe the reccomandation of Dave Neal are too low, how much
Dynagrow should I put in my water for S/H culture?

Thanks

Claude
