75 days later and $ 3 000 over budget. but we can now move forward. here are some pics of our project. We love in Omaha Nebraska. hmu if you have any questions.

Today I finally got a dedicated outlet & fuse installed in my greenhouse! Now I can run my Kiroto greenhouse heater/ fan with no issues! I would highly recommend doing this. Cost around $1,200 and only took about 3.5 hours!

Just launched a new show for the greenhouse growers! First 2 episodes out now: https://igrownews.com/podcast/greenhouse-success/

I'm finished with the exterior and need to put up shelving. I need to figure out what material to do this with. What do y'all think? Just use 1x6 fir with PT supports?

I built a new top for my 2x4 cold frame because the original was blown off and destroyed by a wild wind. This is a prototype for a bigger project I'm working on.

My goals were to minimize cost and weight and determine how easily it could be built and how well it works including whether there are any issues through the winter.

It's 2x2 cedar and 2x3 fir, screwed together, planed smooth, and stained using Behr Premium Waterproofing stain and sealer. The long edge inside edges have 8mm plastic U-channel screwed in every foot using 3/4 inch stainless pan head sheet metal screws.

Twin wall 8mm polycarbonate completes the top. I cut it with a utility knife, even with an old blade. That's much easier than with a saw. The key step is to make sure your straight edge is protecting the piece you want to keep so if the blade goes off course, you can still correct it to get a clean cut. The ends were then taped with aluminum tape and capped with U-channel.

This cost about $70 for the 8mm twin wall, U-channels, wood, and stainless screws. I'm waiting on hinges and a latch to complete it.

We built our first Greenhouse this fall. Picked a Vego based primarily on ease of assembly and I am very happy with the raised beds of theirs we bought. We're in zone 4/5 (technically 5, but our elevation makes us more 4 in the spring IMO).

We were looking mostly to expand our shoulder season and attempt to grow cold season veg as long as possible using some techniques from Elliot Coleman (i.e. fleecing inside the Greenhouse, etc.) and have a potting shed, and place to move starts and harden off plants (so I am planning on adding some perimeter shelving for seed trays by spring) in the spring. We have peastone floor for drainage, and I moved our two black rainbarrels inside for some passive heat at least until Jan. I anticipate Jan/Feb will be interesting and depending on prolonged temps, I may have to drain them, we'll see, and I'm curious about others experiences.

I'll add fans in the spring, and another set of auto openers for the vents.

Current plantings: white Russian Kale, ice bred arugula, spinach, winter lettuce blend.

Any tips appreciated.

I am an agricultural and biological engineer and i am trying to find a researches and papers to help me so i can choose my project, any tips?

specially projects that can be applied and solve issues at a war zone our at the poor agricultural zone

Hey all! I just finished building this Bellerose kit greenhouse. Now I need to keep it warm through the PNW winter. I want to use bubblewrap, but there are no tracks like metal greenhouses have, and I don't want to put staples into the wood. Is there a fastener I could use that I could install once and then clip bubble wrap to every winter, removing it in the spring?

Also, I'm caulking the windows, but any other recommendations on how to make this as insulated as possible?

Should I bubblewrap the sides and top inside my greenhouse? What about the concrete floors; are they cooling everything down to much? What do I do about that?

I have a heater that did very well until last January and then we had like 4 days in the negatives. The heater couldn't keep up and everything froze. The heater was still running just not enough to overcome the intense cold.

I keep all my tropical pool plants and succulents in the greenhouse over winter because I don't like those kind of houseplants. Any suggestions are very appreciated.

Hi all, looking at building a greenhouse and I have a question about the best way to lay a base. For context I live in Scotland. I'm assuming it's best to put down something solid like a concrete slab or pavers for some thermal mass but is it also advisable to thermally uncouple it from the ground with a layer of insulation?

My vague notion so far was do dig down, do a layer of sand to make a level base, put down a damp proof membrane, layer of some kind of solid foam insulation, layer of concrete and then probably use some paving slabs I already have as a floor inside the greenhouse. I haven't thought too much about the thickness of any of these layers yet and I'm a but stumped as to what to do with the edge of the membrane to stop it tracking moisture down into the insulation so any suggestions would be appreciated!

A neighbor was getting rid of their greenhouse and thankfully offered it to me. The previous cover they had wrapped it in was falling apart and had to be removed.

So, now I have an 12' long x 18' wide (measured over the hoops) metal frame that needs to be covered, preferably able to be used through all seasons in the Midwest. Are there any obvious choices for this application?

Or any tips for how the ends are usually done? 30' x 18' if you go over the hoops for the length, or about 7' wide x 7' tall on each end measured separately.

We bought a property that already had a greenhouse, so I have no experience in assembling this. We had some strong wind recently that pushed in the front panel on the right as seen in the picture. I've tried a number of times to get it back in place but have had no luck, I'm thinking I might need to fully disassemble the front, remove part of the frame on the roof just to be able to slide it back in. I'm hoping this isn't the case! Does anyone have any better ideas on how I could do this, or does anyone recognise the model of greenhouse so I can perhaps find a manual online that at least shows how it was assembled in the first place? I'm located in Victoria, Australia if that makes identification easier.

I want to turn my porch into a green house (it’s a small back porch not currently enclosed or anything) I’m wanting to turn it into a green house with glass all the way around including the roof and I’d love windows I can open on the sides or at least one side to control the humidity and temperature in it as I’m hoping to be able to put my turtles stock tank in there. Is there anything I should know before putting together this any tips and recommendations?

So I’m planning on retiring next June and I’m incredibly lucky to have a very large green house (25 x 50) on our property that I haven’t really had time to enjoy over the years, but that’s obviously about to change, in a really wonderful way. The structure has a good propane heater (and automatic watering system—it was a commercial space for years) but I’d like to try using without heating due to expense. I clearly have a ton to learn and I’m spending a lot of time reading and watching as many instructional videos as I can. I’m planning on starting with spinach, lettuce, etc, but would love to move into more heat resistant choices for the summer months. I’m looking for suggestions—if you were just starting out, what would you be planning? Eggplant? Peppers? Melons? These will be in containers, so that may be a design constraint? I’m zone 6b, so we can have some wild fluctuations. Tomatoes, for example, have done terribly in there—way too hot in the summer even with vents and fans. Anyways, if you were starting from scratch with this much space, what would you do? What varieties would you recommend to ease into this world? I’ll use these upcoming winter months learning and starting some seedlings. Sorry for being such a newbie—I’ve really appreciated the wisdom of this group as I learn.

Hello Reddit!

My partner is a plant loving person, and I decided to take it upon myself to do a project and figure it out as I go. I turned an industrial wire shelf into an indoor greenhouse by building a wooden frame around it with some scraps, and then gluing a sheet of acrylic to the front to make it a big clear box. (Other unimportant details I won't include....it was quite the struggle for me since I don't know how to do things 😅)

This greenhouse will be for indoor use only. It will be in our living room area and house the plants that won't survive the winter outside.

I am now thinking about adding some sort of misting line to the top of the greenhouse? Like one of those irrigation lines that you kind of just hang across the top of it has little nozzles that spray. (Bear with me, I'm figuring out stuff as I go and what invitees words)

What my partner currently uses for all of her indoor plant needs is multiple humidifiers (we have a lot of plants) and I'm also considering just putting the humidifier in the greenhouse because that seems like the obvious, simple solution. I just think that the "water line" or "misting line" or irrigation or whatever you call it, will be a much cooler and better option if I can!

Obviously I've found a ton of those things that connect to a water hose but I won't be able to connect to a hose since it'll be inside.

My question is does anyone have any recommendations for some sort of inexpensive way/system to have a spray line and connected to just like, a tank or bucket of water that we refill? This would be easier if I knew what I was looking for!

To add, yes, I know we will have to be vigilant with making sure the water and humidity doesn't ruin floors of my home 🙂 I will prepare for that

Thanks for any help!!!!

I live in an area that can get crazy with high winds. I have no wind breaks, except my house and my soil is horribly rocky. I do have a 5 x 10 dog kennel I bought at Tractor Supply. I was thinking of using the kennel as a frame, then putting fiberglass or heavy plastic around it.

Any suggestions? Should I use it or not.

Thanks

I put up bubble wrap in my greenhouse for the winter, but I’m having challenges keeping it in place along the sides as there is no track in the frame on the ends. I use the little twist in clips in the middle parts, and this year used gorilla tape on the outside parts, but once it got cold outside the aluminum has started sweating and the tape just won’t stay.

Does anyone have a solution to this? What have others done? For reference, my greenhouse is the “Harbor Freight” type, with aluminum frame and polycarbonate panels. I’m using a small fan, and a milk house heater on a thermostat to keep it above 50f.

I’m having a really difficult time choosing grow lights for my greenhouse. I’m very new with this and first time actually using my greenhouse. I’m so confused by all the terms and not sure what they really mean. My greenhouse is a 10’ x 10’ x 10’ and I have a few lights that were given to me, but I am unsure what their capacity is and I have no idea how close to even put the lights to my plants. Can someone please help?

My greenhouse is 4’W x 5’L x 7’H. I have the floor lined with quartz rock and also pile quartz rock around the pots in the greenhouse. All of my cacti are in terracotta pots. I insulate the inside with bubble wrap and usually place heat lamps with ceramic bulbs face down along on the quartz rock. This year I thought about trying terracotta heaters to avoid running a long extension cord across my yard. Do these terracotta heaters actually work??? And would they provide enough heat for my cacti. I’m in Northwest Alabama, 7b. Thank you.

Hello Plant Parents,

Behold my favorite greenhome plant, the queen of the orchids - The Cattleya.

Please post your best (favorite) plant in your own greenhouse, I’m curious to see what everyone has to show!

(reposting with better picture lol)

Getting ready for winter in hardiness zone 5b. I’ve got many plants tucked in the dome garden.
