High Dry Farm, Sultan, Washington….Certified Organic
High & Dry Farm is constructing a new high tunnel greenhouse, in preparation for the new growing season. We have almost completed installation of the supporting hoops. No prefab kits here. The hoops are fabricated from chain link fence top rail, which is bent into the correct curve on-site.
The hoophouse is now producing prodigious amounts of tomatoes and cucumbers, much appreciated by our customers at the Snohomish Farmer’s Market.
Today I harvested the first cucumbers, and the first tomatoes from the hoophouse. Tomatoes included , Alicante, Flamme, Aunt Lucy Italian Paste, Coyote, Earl of Edgecombe, Baselbieter Rotelli, Beams Yellow Pear, Sebastopol, Indische fleiche, Slava, Bloody Butcher, Kimberly, Tigerella, Buckbees New 50 day, Amy’s Apricot, Amy’s Sugar Gem, Washington Cherry, Aurora and Debarao.
Our high tunnel is now fully planted with tomatoes, as well as a few cucumber and melon plants. We are growing 110 tomato varieties this year. Indeterminate varieties are trained to strings in the center two rows. Determinate varieties are constrained with a stake-and-weave system in the outer two rows.
I have removed the last of the tomato plants from the high tunnel and begun replacing them with lettuce and spinach transplants. The high tunnel has performed beautifully in its first summer season.
Tomatoes and melons in our new high tunnel are thriving with many green fruit on both and the first early tomatoes beginning to ripen. A few tomato varieties, such as Debarao have 7′ tall vines.
Starting in January, we covered the construction site with a tarp to kill the grass.
The site was then rototilled…
We built the hoophouse roughly according to the instructions provided by Johnny’s Seeds. The hoops for the high tunnel are just top rails for chain link fence (1 3/8″, available at Lowes). We bent these using a homemade pipe bender, fashioned by cutting a 7′ radius arc into a 2″x10″ board.
The hoops were mounted on posts driven into the ground, and then covered with 6 mil UV-resistant green house poly film.
Part of the job of preparing beds in our newly constructed high tunnel hoop house is removing more than a few large rocks of varying size lurking just beneath the surface of the soil.. I pulled this one out last night. It is, by no means, not the largest rock I have extracted.
A glacier really did a number on our Skykomish river valley during the last ice age. Our top soil, ranging in depth from 1′ to 2′ in thickness, sits on top of a concrete-like layer of sand and gravel compressed by the huge pressure of the passing glacier. Sitting on top of this compressed layer are rocks ranging in size from soft ball size to automobile size.
