Hydroponic vs. dirt plants
When reading about all the benefits there are from eating fresh vegetables., often times it is mentioned all the nutrients, vitamins, minerals, etc. that they provide. Where do all these ingredients come from? Do the plants gather them from the soil and air, and recombine them in such a manor that our bodies can now benefit? Or, do the plants actually manufacture all of those ingredients? Like the minerals, can plants actually manufacture minerals? If plants grow in good old dirt, most everything needed is there. Wondering about hydroponics. Will they only contain what is provided in the water, and be short some other ingredients? Are hydroponic vegetables all as complete as good old dirt grown plants? ? ? Sounds like a silly question, and I donít know if I am making my self clear or not.

NASA does hydroponics on space station
NASA has been doing (and studying results) of hydroponics on the international space station and there has been no mention of vitamin deficiencies or other shortcomings. Most of the nutrient solutions I've seen cover all of the mineral requirements, and they're better balanced and predictable than in dirt. The ability to control PH insures nutrients get "delivered" consistently - something very difficult to do in soil. Check out articles.....

NASA has been working with high pressure aeroponics for years. The plants donít need as much water with that method as they absorb every bit of nutrients from the mist spray. I was going to try a high pressure system this year with strawberries but not sure if iíll Finish building the system on time.
