First greenhouse advice

So I’m almost finished with my first greenhouse. Any advice from the experts on what I can grow year round in the planter boxes? I was thinking herbs and maybe peppers. Not sure if it will get too hot though. Any advice will be much appreciated.

Overhead irrigation for 12ft hoophouse advice

I have a 12ft x 40ft hoophouse with three beds on drip tape that I built last winter. 1st season went pretty well, but I found found myself wanting overhead irrigation on hot days and to direct seed in the fall. My question to those with more experience is: how do you achieve even distribution of overhead in a narrow greenhouse? Idealy, i would run a single line of inverted sprinklers hanging from the center rail. Most heads spray 360 degrees, leaving the corners of the greenhouse high and dry. What do I do to mitigate this?

I dont see a FAQ or other list - Point me to greenhouse reviews?

I took down my kids large swing set last summer (they had outgrown it) with a promise to put in a greenhouse.

I am not looking to build my own from scratch, but finding "reputable" reviews of kits or ones someone will built for you seems like every other topic on the internet, when you search you get the fake review sites.

Is there a good site or list of greenhouses for me to make a good determination of what to install?

I have a 20x20' area, would need to pour a pad most likely, but would like a nice greenhouse. We dont need it to be dirt cheap, and would like for it to be aesthetically pleasing, and the ability to be automated for temperatures is nice.

You see a lot on Amazon or other places, and the afore mentioned websites, that its just hard to judge whats considered quality and whats just a ripoff.

New to this !

Hey guys, i've been wondering for a while about where and how to start with my greenhouse build. I'm still hesitant between a build for conservatory purposes (for my cacti and succulent collection) and a more food producing one. I figured that maybe the best option for me at this stage, is play around with a software that would help me 3D model it and test different parameters. So i would love to hear more from you if you have any suggestions for a good and reliable software. Also, your personal experience with this and how would go about this journey! Thanks peeps !

Plastic Greenhouse Displays/Shelving

Hi friends!

So, last year I built my own shelving out of bamboo and zip ties, which was fine but I didn't treat it and it attracted wood boring beetles. The shelving didn't last through the winter and neither did my greenhouse. I am replacing with a bigger greenhouse, but I'm looking at options for shelving for plastic greenhouses and I'm not finding much other than industrial shelves that are small and expensive-ish for the size I would need to fill.

Not looking to go down the bamboo route again, so I'm looking for suggestions. Needs to be long enough to fill a 20 foot greenhouse & budget friendly!

Thanks so much!

Growing Beans in a Greenhouse

I have a 30x60 greenhouse with several large raised beds. Has anyone had any experience growing beans for drying (I am thinking of a few varieties of small black beans)? I can't find much information on it and I am wondering if anyone has been successful? I don't have much plantable space outside. Thank you in advance for you guidance.

Polytunnel/greenhouse crop suggestions

So Im in my second year of trying to grow my own food and now it's February I'm trying to plan what to grow in my polytunnel. Tomatoes, cucumbers chillis and aubergines worked really well last year but all my peppers had holes in and where covered in aphids, they also didnt seem to grow very fast so im passing on them. I also planted basil in-between my tomatoes as i read it would be a good idea but they went mad and were massive before i even had any tomatoes and I couldn't keep up with taking the flowers off so ended up ripping them out. So is there anything else thats not to difficult to grow that I could try? There are so many suggestions online but it gets confusing and overwhelming so any help would be great! Im also based in the UK

Birthday gift idea for Mom’s new greenhouse? Help

She’s brand new to this and her house is almost finished.

Just need gift ideas to help her get started.

I almost bought some grow lights but don’t want to waste money on something she couldn’t use… or if there’s a better idea to help her start.

I know she wants to start her own seeds for flowers and veggies. She knows nothing about grow lights.. and neither do I but I feel like she could use some? Idk. Shelves? Bug stuff? I’m so lost

She has dirt and compost from our horse farm.

North Carolina if that matters

Thank you!

Greenhouse Plan

So my dad recently passed and he built a green house on our property. It is 60x30’ agratech with 10’ eaves. He kept a lot of tropical plants in the house during the winter and he planned on growing vegetables and other plants but I don’t have the slightest idea how to best utilize this thing.

I looked at a aeroponic system that used a few different types of growing media that seems neat but is a $40,000 prefab system. It would allow me to grow worms, fish, and plants.

I would like to find a system or specific group of crops to plant with a regular continual harvest.

Growing spaces 26ft vs greenhouse in the snow 17x54ft

Hello, I am trying to decide which route I should go for Colorado. Here is what i've decided. They both will be about the same price maybe GITS. Size is irrelevant to me,

Option 1: Growing spaces geodesic dome 26ft. https://shop.growingspaces.com/collections/medium-greenhouse-kits/products/26-foot-growing-dome-greenhouse-kit

Option 2: Greenhouse in the snow. (GITS) 17ft x 54ft and it sits 4ft below grade and uses 8ft deep trench outside the greenhouse with tubes for geothermal regulation. https://greenhouseinthesnow.com/

Does anyone have either of these, if so what is your opinion. Im looking for a 4 season greenhouse and room for a place to relax. I want to be under 30k all in.

Thanks

Transformed old shed into greenhouse (advice welcome)

This has been a cool project! For starters, here are some photos of the nearly complete build and the original shed:

https://postimg.cc/gallery/ZW9h79q

I’m in Seattle, zone 9a. Greenhouse is 12x12 with a small crawl space underneath that I have mostly sealed up.

I used twin wall polycarbonate for the transparent walls and roof. For the opaque walls and roof, I added batts/mineral wool in the studs and 2” to 4” rigid foam insulation on the interior and air sealed it. If my math is right the opaque walls and ceiling should be about R21 on average.

There is power run to the building, so I’m planning on using an electric space heater to keep it warm in the winter. A 700W heater was able to just barely keep it at 60deg overnight when it got down to 38deg last night. I haven’t totally finished air sealing the crawl space and ceiling to wall transitions, so I’d expect better performance once I do that.

Speaking of air sealing…here is where I could use some help. The building is designed super air tight, and it gets way too hot. Like over 100deg on a 50deg sunny day recently. To vent it I’m planning on installing an old bathroom exhaust fan I have to suck hot air out from near the ceiling. In the summer, I’ll be leaving the windows open, but I think it will still get way too hot without shade cloths and maybe even some kind of active cooling.

I’d love to hear anybody’s thoughts about ways to heat/cool the place efficiently. And if you have any other improvements or concerns, I’m all ears.

Thanks!

Need help identifying part

Hey guys! We are moving some gothic style greenhouses. We need to replace some the piece that couples together the left and right side of a hoop in the top of the greenhouse. The couple also has a bracket to hold a support bar. Hopefully this all makes sense! Any idea what this piece is called so I can source a replacement?

framing/ casing for glass panes?

Hello-

I have large glass panes (4 ft x 4 ft and 4 ft x 7.5 ft) that I am using to build a greenhouse. Could someone recommend a supplier for the framing, or casing (I don't know the right word) for the glass?

Thanks-

Tropical Greenhouse in Zone 8

My dream is to have a greenhouse with all my favorite tropical plants & with more knowledge also grow fruits and veggies. Will this even be possible with our extreme summers? There is a local nursery that has a cooling wall in their greenhouse but how do i even start to research that? Do they make panels strong enough to not let full uv rays so i don't cook my plants? This is about a year out but really wanting to dig deep and do some research. Thinking of a botanical garden type greenhouse.

Patio door greenhouse

I’ve been collecting glass patio sliding doors since last autumn and would like to make a greenhouse out of them. Does anyone know a good tutorial or video I can watch? I’ve looked around but most videos are showing what was already built and not the building process

New England pre-purchase advice!

Hello,

I am preparing to purchase a greenhouse and don’t where to begin. Seeking general advice!

  • I want 10’x20’
  • Snow & wind (40-50mph) worthy
  • Prefer glass currently (unless you can conceive me otherwise!)
  • Best heating system for the long winters
  • Anything critical that you think I SHOULD be thinking about!

I’m growing mostly citrus plants.

Thank you!! (Photo of part of my land, for attention 😊)

Natural Gas Heat

Hello! I'm in the process of building a small, lean-to-style greenhouse against the wall of my garage. My garage happens to have a gas line, and while I've always just taken everything inside for the winter, I'm wondering if I could use this gas line and a small heater to extend my growing season.

Does anyone have experience with this or a sense of what I would need to make this feasible?

Thank you in advance!

Turning a walled patio into an atrium

We have a wall enclosed patio area and a brick house. Does anybody have some inspiration pictures of diy atriums? I keep seeing people selling window panes and I was wondering if it would be possible to convert the patio space into an atrium.
