Thanks Nospice! I just like growing things from seeds! I usually pass them on when I get them going so I just wanted to make sure they would be genetically still considered a meyers seedling(and not a "seedling" grown from meyers) :)

Meyer Lemons are usually grafted, or rooted, but can be propagated by seed. When Meyer Lemon's are grown from seed they will usually come true from seed, or fairly close to their parent. Your relative's tree should produce good tasting fruit, either the same as your Meyer or very close to your tree. It takes 4+ years to fruit from seed, when grown outdoor in a warm climate like California or Florida. When grow in a cold climate where the tree is in a building for 4- to 6 months a year, it can take longer.See this WEB site: www.tradewindsfruit.com/meyer_lemon.htm

Just don't overwater. I don't understand if they'll be growing indoors or outdoors (you say 'outside' but you also say 'window'). You'll need to slowly acclimate them to full sun (if outdoors) over a period of 4 weeks or so. Full sun at those temps might even be too much for them. I'd give them more shade if I were you. Keep in mind Meyer Lemon seeds do not grow true to type, so what you have is not a Meyer lemon, but some mix up of the genes in the Meyer lemon hybrid. It may or may not ever bloom for you. Fruit may be inferior. Nevertheless, it should make an interesting foliage plant.

Actually, all you need to do for a lemon tree is plant it in loose soil, water the soil lightly, and stick it in a ziplock bag. See this thread: http://forums2.gardenweb.com/forums/load/trees/msg111341588777.html That lemon tree is mine. I grew from seed. All I did was (STEP BY STEP leaving out absolutely NO information) 1) I grabbed the seed from a lemonade drink made from a lemon bought from a lemonade stand, this past summer 2) put the seeds in a cup of water. All of them sank(sadly, I have no clue where they are now) 3) Placed them in a container somewhere (except for 6) 4) took that plastic cup and cut some holes in the bottom 5) put soil (which turned out to be harder than rock when watered) inside the cup 6) stuck the seed in the cup 7) watered the soil lightly 8) stuck the seed in a plastic ziplock baggy 9) put it on the counter 9) Forgot it was even there About 2 weeks later, I said "OH CRAP! AM I TOO LATE? IS IT DEAD? I CAN'T BELIEVE I FORGOT ABOUT IT!!! OH MY GOSH, PLEASE DON'T BE DEAD! PLEASE DON'T BE DEAD!!!" After panicking and looking for about 20 minutes, I finally found it buried under a lot of crap. I looked into the bag and I'm thinking, "Awwwwww!!!! It's so cute!!!" There was a little lemon tree with it's first two leaves sprouting. After I saw that, I stuck it in the windowsill where it's currently working on it's 5th leaf while finishing up it's 4th. It's the most beautiful thing ever. I would've increased the germination rate though to all six seeds instead of 1 of 6 if I had followed the directions provided online though(nick the seed coat and all that other stuff). But really, just planting the seed and forgetting about it for about 1-2 weeks seemed to work fine. I probably just got lucky though.
