Last night I was grocery shopping and noticed that my Metro sells hydroponically grown lettuce. Not just that, but lettuce that still has all its roots and is sitting in either water or a nutrient solution in order to stay alive until it is purchased. Now, I’ve tried and failed several times at getting lettuce seeds to germinate and grow in my little Yamazen hydroponic system, so at $2.50 I decided to buy a head and see if I could plug it into my hydro system and get it to keep growing.
