I like this product a lot, but I have to say that it was so incredibly difficult to get the cap off the first time round. I had to take it to a hardware store and beg the guys there to help me; they had to get a big heavy wrench to get it off! But aside from that, great product.

Much better results with RO water after switching to this. Seems this formula is more readily available to the plants than most of the other cal-mags out there.

Roger in the Rockies April 10, 2015

This is the best. If you haven't used it, you owe it to yourself and your crops to try it.
