Another seed starting method that can compliment or be used in place of the Ghetto Greenhouse is the "Baggie Method" if you don't have the space or desire to make seed starters out of plastic soda bottles. This method also saves you money because you don't need soil right away to start and when time comes to transplant your seedlings you can put them in an appropriate size pot. You only need a plastic sandwich bag, some seeds and a paper towel.

The kinds of seeds you can start with this method is really only limited by the variety in your collection or what you can find for sale. In this example I started citrus seeds from a citrus I got from the grocery store.
Once I was done eating this particular citrus I saved the seeds and soaked them for a day or so in a glass of water.
this isn't really about growing trees. It's about a method of seed starting, I just used the seeds from a citrus to illustrate how it's done. But now that I see the title I can see why you would think that. I'll edit it.
why should YOU be able to grow the best tree for free, after somone worked for years to achieve it's properties?
Well either the seeds will result in an inferior plant because of hybridizing and or grafting that will be nothing like the parent(s)or I'm ripping off the work of some scientist. You can't have it both ways.
BTW if you are so bothered by people getting something "for free" off of the work of others is this really the best website for you? Just about everything here is based off of something else that someone created after a lot of work.
