I've always been interested in growing in small spaces and am considering maybe growing my own using the Kratky method indoors this winter. (for those of you not familiar, its NON-circulating hydroponics.) However there is something weird to me about 'eating' something that soley feeds off of chemical fertilizers. Then I started thinking, how do I know if what I'm buying IS already hydroponic lettuce. Can hydroponic lettuce be considered 'organic'? I hope not... Hydroponic lettuce would explain how clean they are...

Easy Vacuum packing and nitrogen packing.
Without oxygen the stuff will last for a coons age.
This is how I pack large amounts of cole slaw I make.
I put it on a baggie and force all of the air out and zip it up.
If a person were inclined to they could by a bottle of nitrogen gas and do it at home.
