Hi! I am from Wis. too, so I always get so sad about our short growing season here! Last year I had seen ads for the AEROGARDEN, I think thats what your refering to, growing in water....yes, expensive at first, but man do I LOVE IT! I asked for the first one from boyfrined for Christmas, and grew lettuce. YUM! Not really ALOT of lettuce to be honest, but enough for one.......
So, LOL, for my Birthday, I asked for another......planted more lettuce, THEN I saw a sale, and had a bunch of little Target gift cards and bought a third one, even. Yea, I really like them, but so do the cats. We had to put mini fences around them or the cats wouldve ate ALL the lettuce....my kitchen does look funny though. For the pods(seeds things) you can buy a reusable kit to grow your own seeds. Sign up with the company and they send lots of specials out too, and if you have a Bed bath and Beyond, they have sales and I use coupons too.
LOL, if you want to know anything else, just ask?
