To answer your question about how to add the full spectrum of minerals to your aerogarden. I highly recommend you use concentrated ocean minerals as the source of nutrition for the plants you are growing in your kitchen garden.

The first question you are probably thinking at this point is "what about the salinity in the ocean water?" Very good question...when ocean water is concentrated, about 30% of ocean water is water...when only that is removed, what you have left are all 90 elements from the elemental chart in the exact same order and proportion as nature intended, Including the naturally occurring sodium in the periodical chart.  What you want to make sure is that when you are diluting the concentrated minerals, you dilute to a minimum of 100:1 or 1 ounce of minerals to 1 gallon of water. A little bit truly goes a long way.

Are you growing tomatoes? Let's take those as an example, by nature and genetic permission, tomatoes have 56 of the 90 elements...today, grocery store tomatoes average about 16 of those natural elements and mostly NPK or nitrogen, potassium and phosphate from a petroluem based chemical fertilizer....best-practice organic measures you might average in the low 30's, but with no chemical additives...with ocean minerals the plant now has all 56 of it's genetically required minerals available for its uptake and absolutely no chemical additives! So the tomatoes you are growing are vibrant, when you bite into a tomato fed ocean minerals, you can taste the difference immediately! In fact, you will smell the wholesomness of the tomato if you slice it first. Aaahhh, now THIS is a tomotoe the way God and nature intended it to be.

Another added benefit of ocean minerals as a plant nutrient is now the lycopene in tomatoes is truly a powerhouse and all of the cancer fighting properties of lycopene are fully charged and ready to help your DNA in its natural fight agains free radicals and cancer cells!

I hope this answers your question as to how to grow more nutrient dense foods at home!
