Smart Water: Potassium Bicarbonate, Calcium Chloride, Magnesium Chloride in unknown concentrations per liter.
Appollinaris: 6% Magnesium, 5% Sodium per liter.
S. Pellegrino: 4% Calcium, 1% Sodium per liter.
Another thing I found is a tomato blossom rot cure: Bonide Rot Stop 1.6% Calcium...
Is any of this stuff in concentrations enough to have an effect on a plant? At $2-3 per liter is it a feasible curative measure? What is the calmag concentration on your average East coast tap water???
guineapig, Sanfaustino... awesome. One of the best "home remedies" I've heard yet. How much do you end up using/gal.? Is there any reason not to use it in a hydro setup?
The main drawback with using SanFaustino water in a hydro set-up would be the cost.....its just not affordable to use this water on a large scale......however, as a foliar spray or a small closet situation, it is really an amazing plant tonic especially if you are experiencing Calcium and/or Magnesium defieciencies or lockout.....
SanFaustino is absolutely concentrated enough to help your plants......however, if you wanted a more concentrated Cal/Mag product, the other option is to go to your local health food store and find the most "bio-available" form of Calcium/Magnesium supplements and dissolve them in your water.......make sure they are well dissolved and if possible use Reverse-Osmosis water or Spring Water as a base.....
Glad you all are interested in the search for a more effective Cal/Mg product......
