DIY Micronutrients
 

I have been expermenting with do it yourself micronutrients.

I obtained some hydrochloric acid from Lowes and use it to make ferric
chloride, zinc chloride, etc.

I obtained some sulfuric acid from a battery company and use it to make
ferric sulfate, zinc sulfate, etc.

After the metal is dissolved in the acid, it is important to neutralize
the solution to near 7.0 ph; this can be done with calcium hydroxide
(cooking lime, or a like base--in a pinch, sodium bicarbonate can be
used, or baking soda.)

Anyone else avoiding the high cost of micros and using a similar system
or have any data on homemade micros?
