The last two weeks have been consumed with building a tomato room for the greenhouse. The greenhouse was built 5 years ago at the Homer Flex High School, as part of our building trades class. I knew back then that it should have been 16 feet long, but due to building it at school and hauling it 15 miles to our house we decide on 10 feet. This year we thought it would be nice to have some of our tomatoes in the greenhouse, you can never have enough tomatoes, and all we had to do was make more room. Everyday after school I have been planting and tending to the beds for planting, then I try to build a bit to the addition. I usually make a little bit of headway and realize I need to eat dinner around eight or nine o'clock. Remember, this is the land of the midnight sun and it has a way of possessing you late into the evening. Possessed or not, most of the greenhouse work is done on the weekends. I hope to have it done this weekend, since I have a trip outside in two weeks. It will be wiggle fiberglass on the exterior and visqueen for the interior. I have found that this double wall offers much more insulation that just the wiggle fiberglass. During our nights I can get 4-6 degree warmer than the outside temperature in April. With this design and some heat sinks, i.e. water jugs and soil, this amount of temperature gain matters for keeping frost off the young plants for spring planting. The addition will step down to ground level from the original greenhouse, so we hope to get some added heat in the fall. Also, I am plumbing in 4" pipes under the planter boxes and piping into our exhaust fan at the ceiling level for heating the beds in the spring. Once completed I will saw out the west wall and enter the addition. Currently, the existing greenhouse is working hard and packed with all of our seedlings.
Nicky and I are hardening off the zucchinis, cucumbers, broccoli, cabbage, herbs, and lettuce every evening at the house and down in the greenhouse. It is that time of the year when you are stepping over plants and constantly watering. This year I caught as much snow run off from our roofs and stored it in the garage in several 45 gallon containers. Our plants do better with snow melt we have found. When hardening we have to be careful, because of the day breeze that we get on sunny days can ruin small seedlings. The other day I lost a whole planting of broccoli and cabbage. Not worry, I plant in a continuous cycle so that I have back up plants and plants that can be harvested through out the summer.
Today, Nicky and I bought parsley, broccoli romanesco, and a pumpkin (the only experimental vegetable this year) at a local greenhouse and I noticed that many of their seedlings have the same orange, red, and brown color on the cotyledons and first true leaf. Is it a result of the seedling medium, hers looked like mine, or was it too hot or cold at one time. At school we had the same issue and they are bounced right back, especially the Toi Choi and Tatsoi. We had our first greens and radishes this week at the Homer Flex School Garden. I planted many of my seedlings that have this color in the hoop house and under cold frames this past weekend. Transplants can take a week or two to prove themselves. While I wait, I will continue to plant and build the addition. Garden on!
