Last summer, we took you on a tour of a Buckminster Fuller-style geo-dome greenhouse made on the cheap by John Sondericker in his back yard. We went back this summer to see how it went last summer and what modifications had to be made and how it changed his cost among many other things he learned. Whether you’re interested in the building this kind of dome or not, there’s some great practical wisdom about greenhouse gardening.

    Nice system! Do you also sell at the farmer’s market? My dad had a friend that sold geodesic greenhouse kits back in the 60’s, hippy style. 😉

    The rotting of the bottoms of tomatoes is not due to the particular type of tomato, but rather inconsistent watering or other factors in the care of the plants. It is called “blossom end rot” due specifically to a calcium deficiency. You remedy this by spraying a calcium chloride solution onto the blossoms: follow the directions on the bottle (available at Rick’s Garden center or any other garden shop). I think you can do this and still be organic. The alternative is losing a lot of tomatoes.

    Lots of fun – and lots of work setting up but you’re almost there! What a great way to provide a lot of low cost, organic produce for the family. Loved the sexy lady bugs too.

    And thanks, Betty, for the info. on bottom rot – I’ll forward that to my mom, she’s had the same problem this year and the watering has been inconsistent.

    i have 2 similar kits from that i enjoy every day and will grow year-around at 9000 feet plus…stacked dark water barrels or an open tank against the north wall will act like a heat sink at night to extend your season even more….
