here is my penny worth.

Not sure what you are growing in. If it is Hydroponics, and you are useing Reverse Osmosis Water.. Then for sure have the CalMag+.. It is such a need. And I would think the same thing is true for Soil. RO-- Reverse Osmosis water takes everything out of the water, even the good minerals that water usually has. CalMag+ just replaces these minerals.

These companies do not add these minerals to their nuts, because they are not sure if you use tap water, well water, or RO water. CalMag+ is my friend....

I was taught this just a few days ago from my grow, and these kind people of this Forum corrected it for me.
Chabnoc Reviewed by Chabnoc on . A few simple questions on Cal Mag and ph meter I'm sure all my answers are plastered around here...I keep looking, but blech. I finally ordered a ph digital cker by Hanna (I saw that Stinky recommended those) and some ph up and down. Also purchased the storage fluid for the meter. I did not get the cleaning solution, however, is this an issue? What do I use in lieu of the cleaner, distilled water? Rubbing alcohol? Peroxide? I ordered pint size of these up and down. Is the brand going to be that big of an issue? I bought Eco-Chem. Rating: 5
