Not everyone has a greenhouse. The ones who don't are Dan Hansen, the Lambertsons, the Abajians, the Kinnebrews, Nicole didn't until this year, John Peat, Phil Rielly. I never thought about it, but about half don't.
Dan Hansen has the biggest garden at about 4 acres. Several of the gardens, including the Kinnebrews, the Abajians, the Reillys and even the Trimmers are fairly small. Nicole has the prettiest one followed by her dad at Frank's old place.
