I'm in southern Tasmania and I've got this polytunnel but it's going to be too hot in the day with only a front and back door. Previous owner suggested side vents but can this be done as a retrofit or would I have to pull the plastic stuff off and build windows? I'm not very practical with things like this but I love gardening ...

As i said already, we are looking to get a green house for the first time but we dont want to spend 1000 dollars on it. Im looking at home depot and found some but they zero reviews. Ideally our budget is 300. If it needs reinforcement to it then we can add it if need be. Just wanted to get some opinions from people who might have had some experience with them. We live in ohio so i already know weather is gonna be a problem.

Hey plant friends,

Looking to buy a greenhouse and put it together this Spring, and there are obviously a lot of kits out there. I have heard mixed reviews on the cheaper ones, like Palram, Canopia. I'm looking for this greenhouse to last me 10-15 years at least and I don't want building it to make me want to find a bridge and jump off it. I'm in Atlanta (Zone 8B) and want to primarily use this thing for starting seeds and summering my houseplants, and just for excellent garden vibes.

I'm looking for about 8x10 - 10x10. I've been checking out the vego pacific greenhouse that is definitely on the pricier side https://www.vegogarden.com/products/vego-garden-pacific-greenhouse?currency=USD&variant=40611424665635&utm_source=google&utm_medium=cpc&utm_campaign=Google%20Shopping&stkn=46cf459f3e16&utm_source=google&utm_medium=cpc&nbt=nb%3Aadwords%3Ax%3A21852621771%3A%3A&nb_adtype=pla&nb_kwd=&nb_ti=&nb_mi=263710523&nb_pc=online&nb_pi=vego-greenhouse-10.5-01&nb_ppi=&nb_placement=&nb_li_ms=&nb_lp_ms=&nb_fii=&nb_ap=&nb_mt=&gad_source=1&gclid=CjwKCAiAzPy8BhBoEiwAbnM9OzgSW7czVH8njcDEWYGrGHSdY0dnOqoU4DzQwjNMGHNkIePQ5zhOYhoCCL4QAvD_BwE

I just want to make sure I'm not making a big mistake by buying this pricier one - but aesthetically it's quite nice and it has a gutter system for rain catchment.

Planning out my greenhouse build in a couple months (10x16), and would ideally like to use it nearly year-round (currently in a 6a/b area, right near the line). For heating in the winter, I'm planning on doing a wood stove.

My plan is to use two layers of 6mil plastic (one outside the frame, another inside the frame) to keep an air pocket for insulation, and insulate the north wall as well during the winter likely with paneled insulation. But, the greenhouse will also be home to a couple IBC totes as well. For heating, I'm planning on using a tent wood stove. However, I also have a pretty extensive air-gapped (standalone) solar setup, and I'm thinking that I might be able to use the wood stove and the water up using a 12V water pump to pump water from the totes, through a copper tube wrapped around the stovepipe, and dumping the water back into the tanks (circulating it constantly). I can use a water temperature sensor to stop the circulating if the water gets too hot since I'll also be using them to feed the hydroponics system, and don't want to cook my plants before dinnertime.

Using the IBC tanks as a thermal battery of sorts, I'm thinking that it'll help keep the greenhouse warmer for longer, since the wood stove isn't cast iron (hard to find a cast iron wood stove that small), which would be preferable since cast iron stays hot a lot longer than stainless steel, but on the other hand, I'd have to potentially deal with rust from the hydroponics system misters.

Thoughts?

We want to use wood in addition to brick. Using 6x4 wood, what size would we trim the wood to cut the correct foundation?

I’m hoping to add a greenhouse to my yard this year. Mostly for shoulder season, and hardening off, although I may eventually add heat.

I have a cinderblock garage/large shed in my backyard Thoughts on situating a greenhouse along its east wall vs its north wall? Would leave a few feet in between for future maintenance.

Obviously putting it on east wall would mean losing some westward sun. But it would get almost full sun from about 9am to 5pm in the summer. This site is already pretty level and easier to access

Putting it along the north wall would be full sun all day. I’m in Maryland so this could get quite toasty. The site would have to be leveled and there’s a large black walnut back there(so dropping hazards)

Leaning towards the east wall and just supplementing with lights if needed? Shed has full electric so easy to run it to greenhouse as well.

Am I overthinking this?

So I have been poking around alot with geothermal heating. Lots of them I am seeing are in colder climates with hoophouses. Seems to me a lot of wasted energy on the north side of these. Mine will be a freestanding lean-to style. My original plan was 12" cmu block filled with sand for thermal mass. That is quite labor intensive for a wall 14' tall and of an unsure length.. plus there's is the drawbacks of thermal mass, it only helps if it gets sun, and it still needs to be insulated too. Honestly I think it may cost more than a stick built insulated wall.

We are in zone 6bish. In the southern NC mtns. We normally have mostly mild winters, but a few good coldspells, and occasionally a dip to 0*f or a little below. It can definitely be cool and cloudy for days. We had 3-4 days straight below freezing last month.

Looking to grow bananas, Lemons, oranges, maybe some other things, and for seed starting. I will have some water thermal mass, maybe 3-500 gallons. And I probably will do a few rows of cmu at the base either way. Probably some pavers or rock path.

I want to make it as passive as possible, but I know I will need some power, and want to setup a small solar system and some batteries.

Hear me out!

So I bought a small 700 sqft shack house that I love, but whew! this winter my heating bills have been really high. I have some problems with the doors and windows for sure and it's mostly built on a slab. Some of the floors are really cold and I need to deal with that stuff.

But! here's my greenhouse idea. A part of the house is built over what is known around here as a Michigan basement. There's a 10 by 10 by 8 foot cellar dug out where the furnace and water heater sit. The basement is accessed by a door that is outside and flush to the ground on the South side of the house. An Infrared camera tells me I am losing a lot of heat through the cellar doors. I'm thinking about having a summer project of building a lean to green house that wraps along the South and West outdoor walls of the house. I could keep a couple black barrels of water in there for thermal mass.

What do you think? Good idea? bad idea?

Does anyone have a similar build?

I am not super handy but I have great friends who would help me when I get stuck. If anyone could point me to some DIY for s newbie info for something like this that would be great

One final dream... I would use the greenhouse for starts for my garden, but I would love to have a Meijer lemon tree growing in there. I used to have one in my California yard. Could I have one planted in the ground in a greenhouse like this growing in 6b Michigan?

I live in Zone 7b. What type of heating would be needed for something suitable to grow Avacadoes in? Anyone else doing something like this? I really appreciate a good Avacodo.

I just bought the 10x12 greenhouse from Harbor Freight and am really excited to set it up. However, I am wanting to change the door to the long side so that the length doesn't stick out as much in my yard. Has anyone done this or know if it is possible? If so, how? Any help or advice is appreciated.

I want to get a greenhouse but live in Oklahoma and we have pretty bad storms. I’m looking for a decent greenhouse that will with stand storms for a decent price. Amazon has cheap ones that have reviews stating they do bad in storms. I have a bonsai collection that has to be outdoors and would like to set a nice Greenhouse up for them. Any suggestions !

My pipes keep growing algae on the inside of them, what paint can I use to lightproof the pipes? UV resistant/ reflective? Other suggestions also appreciated, thanks

First of all...this is not self-promotion :) ...I hardly have a following, so it doesn't really matter.

Only posting because I worked really hard on this video and wanted to share it with you all. That's all.

FWIW, I know we all have different experiences with cold-frames, this happened to my experience with the data I got. Enjoy!

I’m fairly new to the greenhouse scene. I’ve been doing research on several prefab greenhouses, but I am interested in possibly looking into a custom builder to meet the specs I need and to work with directly. I don’t know how to even begin going about finding someone who can do this.If I want to go more of a DIY route, do I need to find someone who can help frame it and then someone who can do the glass? Anyone in southern Ohio have any thoughts?

Hey all! Do my mother in law bought this 16x12 greenhouse to put in on our property but i can’t seem to make heads or tails of what to do for foundation. we’re in southern oklahoma do i need to dig below frost line? do i need a concrete base or would cinder blocks be enough around the edge and fill in with gravel for the floor? i assume we’ll need some kind of lining to put under the rocks right? how best to do all this? thank you in advance! i have the link but here’s a picture

Hello everyone. I recently bought a tent greenhouse, a 56” x 56” x 75” (142.24 cm x 142.24 cm x 190.5 cm for non Americans) to put by my back door. The area its in is shaded, and it’s perfect because I plan on using the greenhouse mostly for delicate leafy greens - and I’ve grown them before with great success in that area during the warmer months, the point of the greenhouse is mostly to keep the rabbits, slugs and this family of squirrels I’ve had beef with for years from eating them, as well as hopefully prolong the amount of days in the year I am able to grow leafy greens.

My goal is to put some starts in there the beginning of march, and ideally keep them going year round with minimal electrical heating support. The cold months where I’m at last from November to April, with an average of 40 F (4.44 C) and I’d like to keep the greenhouse above 60 F (15.55 C) if possible.

For the cold months of the year I plan on putting an insulating tarp over the top to prevent heat loss from above, and I’ll put old cardboard between the frame and the plastic cover on all sides but the one with the door to provide extra insulation. There will be a tripod grow light which will supply a little bit of heat, and I do plan on having a heater in there on a cinder block - but I don’t want it running 24/7, I would like to run it ideally 2-3 hours a day at most.

I know a lot of greenhouses have things inside of them that hold onto heat and release it slowly, like big barrels of water, but with my limited space I’m at a loss as to what I can put in there.

I would love tips, as well as advice - even if that advice is that my expectations are unrealistic 😅 thank you in advance

Newbie here, considering my first greenhouse. I have several large trees in my backyard, how much sun do I want my greenhouse to get? I am in central Iowa (zone 5a). Also, I would really love to be able to grow through the winter, is that possible in my zone?

I’m new to the greenhouse scene. Looking to build my first greenhouse.

I know 6mil ploy sheeting is the least expensive and least performing option.

I’d like to retain some heat. Would a double layer of poly sheeting with an air gap between perform significantly better? Would a double lay reduce light transmission too much ?

Was browsing the app and saw that the 8x10 yardistry greenhouse is only $1,499.99. I’m so tempted 🫣

I’ve done the “prebuild” pieces (walls, rafters) but waiting on the weather to clear to put it up outside. Just wanted to update that the new 7x8 yardistry GH at Costco (not online at Costco or yardistry sites yet) is 9.5 ft tall! This is why I purchased it after putting up the original version a couple months ago. This is so much better for my citrus/mangoes with the height. Also has a big window that opens out on one side. In addition, the door can be placed on either the long side or the shorter side, so you get extra flexibility. Just an fyi.

I am in the process of drawing up what i hope is a very efficient design. It combines different aspects of other 4 season greenhouse designs. Only the necessary areas are glazed, the rest is insulated. I used our sun angles for the coldest time of year in our locality, and stopped the back roof glazing so it will deliver full sun to the growing beds, but not hit the thermal mass at summer solstice. It has an area for thermal mass on the back wall, which will be 55 gallon drums and a 169 gallon stock tank. These will double as hydroponic resevoirs as well as a raft bed tank for leafy greens. The plan is to also combine in the use of an insulated concrete foundation backfilled partially with sand as a thermal battery. Then bury two layers of ventilation tubes to pull heat and humidity out of the air during the daytime and release heat at night. Being it will be built in town we are limited in footprint, but will have access to natural gas for a backup heater on the coldest days. Hopefully i can join the crew that grow citrus in the snow.
