Greenhouse kit from Costco.

Calgary, AB(Zone 3a)

We spent the weekend assembling this greenhouse. I'm so excited to have the extra space & climate control. The greenhouse is 6X8. It was not very easy to put together though. A zillion parts with limited instructions. The snow/rain mix didn't help with the assembly. Oh well, done now, plants spent the 1st night last night, which we had a low of -5 Celcius. Everything is fine. Now I can repot everything into bigger pots, since they are still in the seeding trays. YEAH

Looks great! And if it makes you feel any better, I don't know if any of the greenhouse kits that are out there are easy to assemble!

Calgary, AB(Zone 3a)

This is wonderful to have the greenhouse. I started to transplant the seedlings into bigger pots, so they should be huge for May container planting. The hardest thing with the greenhouse assembly was pushing in the rubber seal along the perimeter of each panel. My hand still hurts. I found the handles of the sissors helped, but it was still hard. Even used soapy water, hoping it would just slip in, but it needed quite a bit of force.

We had terrible weather the last few days..blizzard conditions. It was about 5F or -15C. I picked up a Mr.Heater Portable Buddy heater with 2 outputs. 4000BTU & 9000BTU. Friday, the darn thing shut off about 11PM. Started it & set my alarm every hour to check. It shut of @ 4AM & again @ 6AM. These "new" appliance have so many added safety features, they end up being an annoyance. I knew it had to do with the low-oxygen sensor. It was very humid & so cold that the fresh air ventilation was frozen solid. I stuck a fan inside, near the door & it did the trick. No problems since then. Wish I would have thought of it Friday night. It is forecasted to be way below average temps for the next week, so I'm glad I got the new heater.

Here's outside with snow forecasted & cold temps for the next 5 days

Did a little upgrade for fresh-air. The heater burns brighter & less likely to shut-off due to low oxygen.

Joanna-I am really wanting a greenhouse these days but am a little concerned about heating. Your greenhouse looks great! Are you planning to keep stuff in it year round? I would love to be able to keep more cold tolerant plants (down to 45-50 degrees F) all winter, but wonder if that's reasonable with such cold winter temps (we can spend days at a time below 0*F). I was looking at Solexx greenhouses but they are a little pricey. Anyway, I'm very interested in hearing more about your greenhouse and where in your yard it's located-I have lots of deciduos trees but that's really only a problem in the summer time.
Thanks!

Deb,

My GH is 6 feet X 8 Feet, so fairly small. The door is pointing North & there is a 6 foot fence on the South side. There is a Maple tree sorta behind & East of it. I'm not sure if that was a good location, but it seemed to fit in the yard in that location. If you want all year, you may need to consider a a gas/propane furnace. A RV furnace would probably do well, as long as you got a direct vent. You would probably need to put some sort of custom exterior wall in the spot where the furnace would vent...it will be a hot exhaust. Electric heaters would probably be expensive to run, plus are a bit iffy with an environment with water. There is a fellow in this area that has a few bigger greenhouses in his yard & he has large rainbarrels in the greenhouses lined up along the north wall, creating a heatsink. I guess it would depend on what size GH you get. It is amaing how much heat is generated from the sun...but once the sun sets it cools off fast.

Thanks for the information, Joanna-I'm really torn between getting the greenhouse (which I have AWLAYS wanted) and rigging up more lights in the basement for growing. Things just grow better in a greenhouse . . .

Joannabanana - how are you feeling about your greenhouse? Ihave looked at the Costco kits and the price is certainly good. Is it holding up? What kind of a base did you put it on?

Thanks

2757,

It was awesome. In August, Costco had another sale, so I sold the 6'X8' and bought a 12'X8'. I put a base of double layer landscape fabric. I plan to use pea gravel, with small stepping stones down the middle. We made a frame out of pressure treated wood and anchored the frame with heavy duty auger style anchors intended for big tent type carports. I plan to get auto vent openers for the roof vents. Will use the propane heater as before. I'm hoping to get the new one completed within the next few weeks.

That's just great. With as cold as you must get, I have high hopes for growing in the winter. What do you grow in the gh over the winter?

Calgary, AB(Zone 3a)

Nothing from November to Mid March. There isn't enough daylight hours and it would cost a fortune to heat it. Also, the freezing temps for weeks/months will kill most of the bugs that are in the GH. We will get 12+ hours of daylight around March 20th. For us # of Daylight hours (around mid month) is as follows: Nov: 8-1/2hr, Dec 8hr, Jan 8-1/2hr, Feb 10-1/2hr, Mar 12hr, Apr 14hr, May 16hr, Jun 16-1/2hr, July 16hr, Aug 14hr, Sep 12hr, Oct 10-1/2hr

In mid-June sunrise is 5:20AM & sunset is 10PM
In mid-Dec sunrise is 8:40AM & sunset is 4:30PM

Oct, Nov, Dec, Jan & Feb just don't have long enough days. Dec, Jan, Feb can get as cold as -40 C or F for a spell.

(Sheryl) Gainesboro, TN(Zone 6b)

Yipe!!!!

I would have a tough time Oct. through Feb. I think. I'd gain 50 lbs, start watching TV (Jerry Springer, probably) or just go wacko.

Still not done, but should be completed by the weekend. It is enormous compared to the little one from last year.

I put about 2200 lbs of small rock for the base.

GREAT PICS. CAN REALLY SEE HOW IT GOES TOGETHER. DOES THE POLYCARB COME WITHIN THE GREEN FRAMES OR DO YOU SLIP IT IN SOMEHOW? I'VE READ LOTS OF HORROR STORIES ABOUT HOW HARD IT IS TO GE IT IN. THANKS AGAIN

Calgary, AB(Zone 3a)

"Everything" is in pieces but very well labeled. If you follow the destructions exactly, it is very easy to put together....just a zillion parts to work with. It may be a bit overwhelming when you first start, but honestly, it is not difficult. It will take a couple of days to assemble if you take your time and well worth it.

Palestine, TX(Zone 8b)

My 6x8 greenhouse is an Easy2Build. My s-i-l did it by himself in two days. The base is a frame of treated 4x4x8 with bolts drilled through and set in concrete. The floor is covered with weed block and eventually pea gravel. Then there is cedar sitting on the 4x4 to protect the aluminum. The covering is heavy poly plastic. I have had to use it three times now to protect plants from freeze. I use a Mr. Heater Buddy connected to a 20lb propane tank. I set it on low and it keeps the gh 20 degrees warmer than the out side air. The slight gaps between the wood and aluminum frame seem to allow enough fresh air to the heater. We also drilled a hole through the 4x4 to allow the hose from the tank to the heater. This also lets enough air for the heater.

I have been very pleased with my GH. I bought it off of e-bay for $300.00 including delivery. I have outgrown it already and am planning on tearing the sides and roof off of an old shed and putting corrugated clear panels for greenhouses on it. It is much bigger and would be able to hold my larger plants. But I say again, the propane heater is a blessing. I keep track of the amount of hours used so I can be sure that I don't run out in the middle of the night. BTW, Joanna was the one who confirmed for me that the propane heater would work. Thanks again Joanna.

Well the new 12X8 is 99% complete.

The one difficult task is getting the rubber seal in place

Soapy water (carwash soap doesn't affect the rubber) and this handy little window-screen tool makes the job a little easier

look at all that room. How long do you think it will take for you to fill that one up?

Calgary, AB(Zone 3a)

I won't be putting anything in it until Mid March...so by April 1, it should be full. I'll start the early stuff, petunias and such, indoors under lights & move them in the GH then. It (GH) seems huge compared to the 6X8 one.

Palestine, TX(Zone 8b)

I bet it does seem huge. I love petunias. I have the surfinias and calibrochoas. First time with them this year. They have been beautiful producers. The surfinias have a great scent. The purples do better in the heat than the pinks. They are self cleaning and constantly fill in from the top to bottom. No need to deadhead or prune back leggy stems. Mine got 3 ft long hanging from the pot. The calibrochoas, or mini pets, are also self cleaning and get very full. I got the Terra Cotta. I highly recommend them to petunia lovers.

(Sheryl) Gainesboro, TN(Zone 6b)

I was thinking about doing a mixed pot with the two this year, but I can't find any seeds for the Calibrochas, *sniff*.

I *love* the Terracottas. Bee-yoo-tee-full!

Palestine, TX(Zone 8b)

Sheryl, I'm not sure about the calibrochoa seeds. I think you propagate by stem cuttings. If I find seeds, I will harvest them and send you some. I don't see seeds on them like I do the petunias. But I will check today and see what I find OK?

They make the most beautiful full round potted plant. I put three small plants to a 12 in pot and it just exploded.

Calgary, AB(Zone 3a)

Stokes has the best description for the different types of petunias. I start all mine from seed. I like the Waves, Tidal Waves, Shockwaves, Ramblin', Avalanche, Opera supreme. All are Multiflora, and don't require diligent deadheading. I'm the worst deadheader. All that I mentioned are great performers & full of bloom until the killing frost. I like the Supertunia Vista series, but they are not avaiable by seed. I hate buying bedding plants, since all the growers use those terrible peat plugs with the mesh lining. The lining restricks the roots, becomes a wick and is a problem. I usually slice the lining or pull it right off. The plants do much better without it. The Calibrochoa are not available in see form. Probably a few year until the plant police will allow seeds on the market. Bacopa was just allowed to be sold in seed form last year for the 1st time.


Palestine, TX(Zone 8b)

I have a petunia that self sowed from a light pink mother plant. It has grown and is blooming the deepest pink. I love it. It was a nice surprise. I have seedlings popping up in the pots of my petunias and pink surfinia. I haven't had to buy any bedding plants since harvesting the seedlings. I have successfully gotten cuttings to root off the purple surfinia. The pink is self sowing.

I have heard of the Waves but not the others. I am constantly amazed how many varieties there are of one plant.

(Sheryl) Gainesboro, TN(Zone 6b)

Thanks - if you find some, great! I had tried cuttings, too, but didn't get too far. Not that a glass of water on the windowsill is always the way to do it, lol...

Palestine, TX(Zone 8b)

I will try cuttings. I cut the top of a stem off and take off the bottom leaves and stick in rooting hormone. Then plop it into the soil and see what happens. I got my purple surfinias that way. I don't know if the seeds of the calibrochoa are sterile or not. Some site said the surfinias were sterile, yet I have little surfinias growing in the pot of pinks. So I harvested some seeds from the purple and pink and peat potted them. WE'll see if they germinate. I'll let you know if I find calibrochoas. I will check tomorrow. I forgot today. Sorry.

(Sheryl) Gainesboro, TN(Zone 6b)

No biggie, just LMK if you run across them. Of course, it being complete winter here, we no longer have anything in stock that doesn't look like Christmas.

Palestine, TX(Zone 8b)

there are some good sales at Lowes in the garden dept. Trying to get rid of their summer and fall stock before it freezes. I got a plumbago last spring that was leftover from the previous year. It cost a dollar. It is so big and pretty now. Pansies are out by the hundreds at Wally World and Lowes. My calibrochoas, surfinias, petunias, geraniums, encore azaleas, clematis, lantana and butterfly bushes are all still blooming. The butterflies and bees are eating away.

(Sheryl) Gainesboro, TN(Zone 6b)

And what's good for them, is good for us!

Palestine, TX(Zone 8b)

I'm gonna have to write myself a note to check the calibrochoas for seeds. Was out all day with the hubby and forgot when we got home. Tomorrow I will be bringing them out of the GH and watering them. I will try to stick anote to the GH door. If I had all my brain working I'd be dangerous. :)

As a true blonde, I totally understand.
