Cedar Greenhouse with Potting Bench

Project by jhtuckwell posted 209 days ago 1203 views 4 times favorited 15 comments Add to Favorites Watch

We live in the foothills of Colorado at 7100’ and growing anything outside usually turns into fodder for deer, bear, foxes, coons, squirrels, bobcats, moles, etc… So I promised my wife I’d build her a greenhouse so she can grow vegetables and herbs without competing with the local wildlife. It also extends our growing season as we can experience frost up here as late as Memorial Day and as early as late Sept. After looking at various kits for sale we decided to build our own. It’s an all cedar construction with a 6”X6” treated timber base, stainless steel support brackets, screws and nails, 8mm polycarbonate, twin wall panel sides and roof, 16” thermostatically controlled fan to maintain the temp. at 85°F, planter boxes 30” high with a center aisle, 84” X 24” potting bench with a faucet, sink, upper and lower shelves and potting area with a dirt collection box and a timer controlled drip system. I laid a ¼” steel mesh under the floor so the moles and squirrels cannot dig under and up through it and built a cedar screen door with a removable polycarbonate panel so we can close it up during the cooler nights and leave it open all summer long for ventilation. We do not plan to grow in the Winter but we could with a space heater. The walls and roof supports are cedar 2X4 and 4X4 beams on 24” centers with a 4X12” laminated center beam, 16’ long to handle the snow load. We stained it with 3 coats of Sikkens to match our log home. For those of you who would like an outdoor project this summer and have the space, the joy of eating fresh vegetables all summer long is well worth the effort and it keeps my wife very busy so I can spend more time in the wood shop.

This is a dream greenhouse. Beautiful and highly functional. Did you buy plans or design it yourself?

Hi Robin: I saw a design for this from a greenhouse supplier in British Columbia that sells cedar greenhouses. We used that as a basis and then did our own design. Thank-you both for your compliments!!!

Hi Green thumb:

We heat it at night in November and part of Dec. to get the most out of our vegetable crop but then it sits empty till ard. April 1st. Because it’s not unusual to have frost all the way thru till May.30th we keep a small space heater with the thermostat set at 40°F in there during the Spring and Fall. We get a lot of radiant heat during the day year round as we’re at 7100’ and the sun gets pretty intense so we could keep it warm all Winter but we have an active travel schedule during those months so elect to “suffer” through store bought produce in the Winter!

I just built a small greenhouse andl ike you, it isnt unusaul to have frost to the end of May, again in September.

I travel a lot in the winter too, blowing snow, up and down the driveway, up and down the driveway, up and down the driveway. At times that driveway,laneway, might as well be as long as the Alaska Highway.

I have to ask one more question. Why did you put the raised garden around the perimeter, and not down the middle?

I know your weather predicament well as I was born and raised in Winnipeg and spent 10 years traveling a sales territory from Wpg. to Thunder Bay via Kenora, Dryden, Pickle Lake, Atikokan and Fort Frances. We put the raised garden beds around the perimeter of the green house in a horseshoe shaped design leaving the center aisle open for access. We found that 36” was a maximum reach from the aisle to the back of the raised beds and even with that my wife needs a small step stool to reach into the far corners. The raised beds are 30” high with a 2X6” ledge and are made of treated lumber lined with plywood and covered all around with a thick, rubber sheeting that they used for roofing to prevent the dirt and moisture getting to the plywood and rotting the wood. So far it’s worked well but I dread the day when we need more planting space!!!

I’ve been to Winterpig many times, same with Tunder bay, and pickle lake (god forbid).

Thanks for posting this, it really is a beautiful greenhouse.
