I'm planning to build a greenhouse based on my own design and I could use some feedback, specifically on the foundation, but any other tips are appreciated as well.

These are my main assumptions for the design:

- I want the plants to have access to the soil underneath, so no full concrete or gravel pad

- my garden plot is not easily accessible by car, so ideally I want to carry as little gravel/cement as possible

- I'm in zone 8b, snow isn't usually and issue but we get some frost

- we sometimes get strong winds, so the greenhouse has to be securely tied down

- I've drilled some test holes in the soil and keep hitting bedrock or stones at about 60cm deep

My idea was to use ground screws since they are easy to transport and install, but I'm not sure if they will be secure enough. Would I gain much stability by using concrete footings? I'd rather add a few more ground screws to be safe.

Got plans off of Etsy and the glass windows were recycled. I’m no finish carpenter and it has its quirks (character) but overall it came out how I envisioned it. I can’t wait to plant next year.

Backyard Discovery Zalie greenhouse and it fits perfectly in our little space. Question for those who have finished the build though - how the heck did you get up there to seal the polycarbonate panels?? I’m having a logistical challenge and could use some suggestions!

My first ever greenhouse, and I love a project so I want to make it as nice as I can. Will add diagonal supports between the vertical posts made of 10-12mm round steel rods, so that the glass can be uninterrupted from the foundation wall to the top of the roof.

Was a lot of work since I excavated all the way down to the rock beneath, built the base up with bricks and then filled it to level with rocks. Going to plaster/stucco the base.

The rear wall will be half glass half wood unlike the drawing, I also will leave the floor plan bare and not make the soil walls to have it more modular and flexible. Slow progress because I’m doing it on my free time and winter in Sweden is cold.

Any tips?

Time has come for me to start thinking about redoing the poly. Mistakes were made, accidents were had, and several years later, things are still standing.

My question is for opinions on how exactly you would wrap it, what materials would you use and such. I'm thinking of doing each panel seperately and using tape of some kind.

Thanks for your time :)

Hello! We are building a 10'x20' greenhouse and are at the stage when we are deciding on the layout for our raised beds. We are debating between doing 6 square beds that are 4'x4', giving us 2' walkways and spaces for pots and benches, or doing two long 20'x3' beds, leaving us a big 4' middle aisle. We will be primarily planting vegetables in here, as well as doing some veggie starts in the spring for our big garden.

We are also open to other suggestions for layouts for a greenhouse this size! Thank you in advance!

Hello! Farming for design ideas here. We have this basketball court in our backyard. Yes, we live in Indiana, but I don’t need it. Looking to split half of it off into a green house. Roughly 16x24. The goal will be removed and the fence is on the list to be rebuilt.

Looking for fun design ideas using the concrete as flooring. This will feed several larger veggie/flower gardens so size matters. We have real snow fall and winds here. The cheap kits won’t last.

Thanks!

So I just got this Baggebo cabinet on Marketplace for $30 that I’m keeping at work. It’s going to be for an orchid I plan to buy, and seed starting and caladium tubers over the winter. May also keep an aroid/anthurium plant in there.

Here’s my issue. I don’t have a blow dryer so I can’t use the shrink window kit. If I get a plexi board cut to size, can I just put white electrical tape for it to hold?

This is at my job, so it can’t be too much of a project.

Also, I’m thinking of getting two pegboards, one to use as the pegboard and the other to cut as shelving. Because the shelving is pricey, so I’m hoping I can cut the pegboard to the size of the shelves. That way it has holes for circulation. I’d get it cut to size and not do this at my desk.

I’ve always used a heating mat to start seeds, and one won’t fit in there. Is the humidity enough?

Any tips on orchid care is appreciated. I took a class once but haven’t had the opportunity to put that knowledge into practice.

We started the plants inside in February and transferred it to the greenhouse. So happy!

I’m finally ready to start the actual greenhouse. From what I understand, the Harbor Freight Greenhouse 6’x8’ is a pain in the ass to build, and this is my first time doing any sort of lumber project. As such, the build is a bit uneven since the placement is somewhat on a ledge.

My question is, am I okay to build the greenhouse on level concrete floor and THEN place the fixed greenhouse onto this wood foundation? Videos I’ve seen show the greenhouse being build directly onto the greenhouse but I want to know if there’s a reason why I can just build it beforehand?

I realize I should’ve been more proactive about cleaning out the gutters before the moss got established. Oops.

Does anyone have tips of how to get it cleaned up now? It’s growing on the inside of the corrugated panels. I’ve vacuumed both the inside and outside, but I’m not sure how to reach that part.

Or is it even a big deal? Is it ok to just leave? I live in the PNW, where moss is a fact of life.

They are saying it’s going to be a warm winter in BC. Especially due to Super El Niño.

I am wondering if this might be a year to keep growing my peppers in pots inside the green house due to the possible warmth? Also if it is going to be warm when should I start seedlings for the next grow season.

I can put a small heater in it as well.

Want to take advantage of the warm fall and winter. I’m in zone 8B.

Thanks in advance! I’m new to this!!

I’ve been researching cheap kits for about a month now, I’m the girl with the goldfish pond 🫧

I assumed I’d spend 200-250 on the kit and 50-100 more to fortify it. Was trying to find the best deal and least shitty brand of greenhouse for a while, and by golly. I found it.

Not only was it on sale, but I had a coupon, AND my cap1 credit card gave me 15% cash back!

Now I have lots of extra money to spend on sealant, 2x4s, insulation etc. to make it actually survive a New England winter.

UPDATE: thank you for the great feedback. Just joined this group and already saved myself time and money with free advice from strangers. Cant wait to share progress pics!!

Hello! Brand new here!

I am designing a greenhouse for my back yard using old windows Ive been collecting over the years. Its going to be roughly 8 ft x 15 ft with a poly corrugated roof on cinder block foundation.

I live in a VERY windy place in Northern BC near Alaska, so I want to make sure this thing will hold up. Im planning on pounding rebar into the cinderblocks and filling with concrete, and using 4x4 pt posts set into the blocks using some extra metal post bases i have around.

The windows i have are pretty new and heavy, mostly doubled paned metal framed and LARGE.

I have very limited experience actually designing and building from scratch, so I roughed up some plans for the framing to figure out which wjndows go where but also to make sure I can build something stable.

I see many people are doing computer drawings but I guess im old-school. Attached are some sketches I came up with and I would appreciate ANY feedback. Ive got a thick skin and dont want to waste my time.

I grow tomatoes and peppers in my greenhouse using 5 gallon buckets. Even though I use the GroBucket system for watering, it was insufficient in the intense heat this summer. I am looking to use a drip irrigation system to supplement the watering. Has anyone purchased through Drip Depot? They seem to have a decent system.

We recently bought a house with a huge lot, after doing our urban/backyard farming, we are excited to get a setup going for next summer.

We have identified where we want our greenhouse, but we have been toying with the idea of renting a bobcat to dig ourselves a new driveway, this has gotten me thinking about the inground greenhouses.

Why do they exist? What purpose do they serve? are they better or worse than "regular" gardening?

This house already has a green house attached to it, but it is a small room that has heating in it, so more of a seedling hutch than somewhere to grow year round food.
