First serious attempt at an outdoor grow here in Da U.P. of MI....
Understanding from limited past experiences, PM is a certainty, it's just a matter of how to contain it. Enough research was done to conclude that Potassium Bicarbonate is an effective weapon. Products like Green Cure, Mil-Stop ect....What they all share, is a high percentage of that same active ingredient, and a bit of an inflated price tag, considering the ingredients. I always read the ingredients.
GH pH Up, is Potassium Bicarbonate, and Potassium Citrate, and is dirt cheap.
There is no way, that I can be the only guy who noticed that.
I put a TBS of the powder in a 2gallon bucket with 100ppm tap water. The pH of that solution was near 10.
It has wiped out any early signs of PM on the lower leaves.
Somebody else, tell me you've done this.
