    Hello All

    I would like to share my story about yet another attempt to prove everybody wrong and grow fruit-bearing Grapefruit and Lemon trees in Southern Ontario!
    This is phase one of my story (germination). Stick around for another 5-10 years if you would like to see how this turns out! :-P

    I am located in Kitchener Ontario (Border of zone 5b and 6). I have done the following things so far, based on information primarily from this forum:

    1. Collect 8 seeds from Florida Grapefruit and Sunkist Lemons (4 each)
    2. Place the seeds in hot water for 5 minutes
    3. Remove the coat from two of each seed type
    4. Plant the 8 seeds in two types of soil:
    Jiffy seed starters and black gardening soil - With and without the coat
    5. Enclose the seeds in a plastic container with plastic wrap (a few holes for oxygen)
    6. Place them under a light bulb covered by an aluminum turkey roasting pan

    The temperature inside the container is above 50 deg C (122 deg F) with a 100 WATT incandescent light bulb, so I have replaced it with a 40 WATT bulb. I am trying to maintain a temperature of 35 deg C (95 deg F) as recommended by Millet in another thread...

    Does anybody have more recommendations?

    Yes, 86-90F is a better germination temperature for both, but especially for Lemons. - Millet (1,385-)
