Saves money compared to Tower Garden liquid fertilizer

We got tired of spending $60 or more for "official" Tower Garden fertilizer so we looked around and found out about Jack's A and B powderized nutrients. Just make sure to mix each independently before combining the two liquids or it will all precipitate out at the bottom of the liquid. I also slightly heated the water on the stove before adding the powders so they would completely dissolve.

Healthy plants

I now have the healthiest plants that I have ever had. For the price and the control between parts a and b makes this the best fertilizer I have ever used.

Seems to be working well so far.

It takes a little bit to dissolve, but seems to be helping the growth.

Works great and very economical.

Use to use VBX and switched to Jacks. I bought the 2.5 lb bags to try and my only concern was not buying the 25 lb bags.
