ROFL! I was stirring forever trying to get a Plantex and potash mix to
dissolve this afternoon. I kept adding more and more water - it's half
the strength that I wanted. *sigh* Is it just me or does it seem like
you have to add incredible volumes of PMDD to get decent amounts of
ferts in the water? I'm looking at 1.5 ml per 10 gal per day of my brew
to try Tom Barr's Estimative Index dosing.


Elaine, I made up two potions to solve this problem. My "tea" is
Plantex and magnesium together. I think it is 1 tablespoon each to
500ml water. My "pink stuff" is KNO3, KCI and a touch of KH2P04. I've
been talking to Greg Watson and at his suggestion I mix separate
batches to solve the solubility issue.

For what it's worth, I add 15ml of tea every other day and 20 ml pink
stuff every other day. The pink stuff is (I think) 4 TBL KCI, 1 TBL
KN03 and 1 tsp KH2P04 in 500 ml water. 55 gallon tank with C02 @ 30ppm
and full of plants.
