I was actually looking up some hydroponics information, but I came across some interesting web sites via Google images. It turns out lettuce will last much longer in the fridge if it is kept in an airtight jar that has had all the oxygen removed. The lettuce is washed, dried, and cut first. According to the site, the lettuce will last fine in the jar for up to nine additional days without any brown spots.
What I like about it is, the lettuce is already prepped for a salad. Salads are a pain to make. This way, I just need to throw on some sprouts, and mix up a quick dressing.
I used quart sized wide mouth mason jars, and the Food Saver attatchment with a hand pump to get out the oxygen. I find I like this method. Just dump the lettuce in a bowl, and half the work of making a salad is already done. It has kept very well too.
There is another type of "lettuce in a jar" that I'm also trying out. According some literature by a prof. out of HI, hydroponic lettuce doesn't need an air pump! Apparently you can grow it in a container with all the water and nutrients already added, and as the water level descends, the lettuce will send both roots down to get the water, but will also change its upper roots into oxygen gathering rooots. The upper roots won't dry out in the high humidity of a closed bottle or jar.
I seeded some "lettuce jars" today to see if I can make this work.
