Tomatos

Today I planted some tomato seeds to see if I could germinate them in the garden room.  I would like to have some fresh tomatos during the winter.  I decided to plant the seeds in regular potting soil and once they are transplanted into bigger pots I will mix some worm castings with potting soil to see what the outcome will be.  I have always heard that the greenhouse tomatos don't taste as good but I wonder if this is true with garden room tomatos with a worm castings mixture.  I will post pictures later.
