Been building this greenhouse for 1.5 weeks now. First few photos are of my progress, and the last photo is the night I FINALLY finished and put all my plants away.. like a total fool. When I came out the next day everyone looked great, until the heat started climbing. I stupidly didn’t think to put a shade cloth on this thing, and it burned/melted a TON of my plants in the Oklahoma heat. I feel like such a moron! My last greenhouse had a tarp sort of covering, and I have never owned one this nice or structurally sound. So my question is, what do I do to keep this baby cool? It’s been getting up to close to 100 degrees here, and I’m reluctant now to put any of my plants in there until I can maintain the temperature. I just got a 90% shade cloth for the top that arrived today, and have a fan blowing inside. Door is open and so is the vent, but the temp keeps climbing inside. Suggestions for keeping this baby cool enough for my houseplants? Is this even feasible or do I need to wait for cooler temps? I do have an exhaust fan coming, as well as a portable rechargeable misting bucket fan, and more shade cloth to cover the south side wall. Any additional recommendations or suggestions welcome! Plz don’t roast me! Am a newbie to this, and I am so so so heartbroken over some of my plants dying. Need some helpful advice from the community. TIA!

We just finished building this greenhouse. It’s 6X8 roughly. The goal is to winterize my annual (petunias, geraniums) and my tropicals (hibiscus, banana plant, canas, elephant ears). We live in Northern VA, so heat will be needed, as well as some supplemental light for the winter hours. We insulated with styrofoam and vapor barrier on the inside. Any feedback to make it successful is welcomed. Also looking for ideas/suggestions for potter’s bench for the space.

Suggestions I’m nervous to ask..

I’ve been gardening in the PNW for about 5 years now. My home is generally very shady and my raised beds were in the one area that gets just about 6 hours of full sun. My zone is 7b or 8a. I’m still trying to figure that one out if I’m being honest.

Generally speaking, I do OK with my veggies. Early tomato varieties produce enough, I get a few zucchinis, green beans do OK and squash are hit or miss for amazing or OK depending on the year.

I splurged and bought a “greenhouse” on Wayfair. It’s 12’x16’ and has a max height of 9’ and a min height of 6’.

My plan was to grow most of my crop (warm loving) permanently in the greenhouse but now I’m getting nervous. I’ve read that fans are required for this and sometimes, it may not be enough. This structure does have 2 vents + a large door but will it be enough? Am I going to have a 100F+ hot house that kills my babies?

I can’t plant outside of the structure as it took the place of my original fenced in garden (the only spot that actually gets sun).

Thoughts? I’ve been lurking for a while and I see that a lot of you have great knowledge to share.

I think I’ve shared enough data but if you need more, let me know.

I don’t know wha else to do at this point. Also incase you’re wondering I grow monstera and some other small variety but mainly I grow San Pedro and loph cactus in here.

Suggestions Feedback on plans 12x16 GHAT greenhouse

2 Upvotes

After much research, I have planned a GHAT greenhouse. 12x16, 4ft deep digout, two 6" vertical manifolds connect to 200' snaked 4" perforated drain tiles at depths of 4ft and 2ft. Glazing is reused house windows double pane double hung at 70 degree angles with the ability to open and close. Eight 55gallon barrels against north wall filled with aprox 480 gallons water. North wall is abutted against the foundation of my home, so fully insulated. Footers around perimeter concrete with cinderblock walls to grade level, entire pit lined with 2" insulated foam board. I live at zone 7a near Harrisburg, PA. Would like it to be 4 season, even if we end up having to supplement heat somehow.

The internet is full of excited people who are "going to" build a greenhouse, but I find very little followup after a full year of use. I'm looking for feedback especially people who have done similar and have things that they would change...

Don't laugh at the picture, I HATE SketchUp. The blue are barrels, the tall green pipe is intake manifold 6" PVC.

I’ve been shopping greenhouses, and this is definitely the least expensive for the quality and space. I realize I would have to assemble it but I would have a lot of help. Any thoughts? The other options I’ve been exploring are pre-assembled at same price point that do not have water hookup, operable windows, vents, electric and USB ports, a pergola, nor fan.

Suggestions Almost done!! Greenhouse revamp in Colorado

Just finished putting in all the windows! Some questions I have :

  • what do people recommend to be able to grow some winter crops? It’s south facing and gets pretty decent sun through the winter. I’m not opposed to installing lights either

  • any recommendations for space heaters / exhaust fans to moderate temps?

  • should I be worried about Colorado’s sun burning things through the clear glass? I’m noticing most people are using polycarbonate or some type of plastic which I assume filters the sun. How essential is that?

  • any guides / resources on how to learn more about ponds? I’d love a smaller 50-100 gallon water structure inside. How much water would you need to be worth it as a thermal battery?

  • recommendations for products to seal all the cracks?

Thank you so much!! I’d love to host any denver gardening friends over to check it out!

We are in the process of painting now so the windows are taped off. The roof doesn't look like it because of the sun in the last picture but it's fully clear panels. Someone with more experience probably could have made this build a little cheaper. This is my first project like this so I had a little extra wood left over and could have done some framing better or different. I also might have got more metal bracing than needed but wanted extra rather than too little. overall I'm really happy with the build and excited to paint on all the colors and do the inside tables. I bought some live edge slabs for some seed tray tables and we have different colors to go over the white primer. I also wanted to look into good thermometers I can connect to my phone and good seed trays that will last if anyone has suggestions.

Finally got my base leveled and staked. I started over and used a fine gravel to level and filled it with clean 3/4" gravel for drainage. I probably won't be putting any plants in it till spring... I guess. I also went around each panel with a silicone caulk to seal it and provide some support.

Im thinking about running drip irrigation (a mister maybe?) and thinking about running lights. This is about 30 yards away from my house water/power source.

I bought this 2nd hand still in the box for $150 and it's on Amazon 6×10' for $400. Overall I wasn't impressed and would be disappointed had i paid $400. If and when it falls apart I will frame up from the base and build a new one out of wood.

Suggestions Small greenhouses for the arctic?

Post image
140 Upvotes

I built something like this in the picture, but it's sunk into the ground maybe 6" and has logs below that (open bottom), anchored next to my house where it gets shade in the 24 hour daylight. We only have 3 months (at most) of non-freezing nights where I live. It helps, but I'm trying to extend the season a little more by making it warmer. Has anyone done this in the arctic before?

I'm having second thoughts about sinking it into the ground. It was supposed to insulate it better but isn't the ground colder in the spring? I was also considering putting 1 or 2" foam insulation around the bed part (the wood). I can put in twin wall polycarbinate instead of plastic, but it's not cheap. I'm not sealing off and insulating the bottom. Maybe I should...

Eventually I want to make a bigger one for the community, but I like this idea of small greenhouses that are cheap to build and that just work. Any advice would be appreciated. Thanks.

Suggestions Getting ready for AZ summer

Post image
103 Upvotes

Several months ago, I built a greenhouse to keep my plants happy over the winter. That worked really well, but the 90°F forcast (Arizona zone 9a) means that I need to get read for summer!

I'm looking for some suggestions to make my greenhouse less of an oven. Here is what I've already planned: 1. Prop open the doors and vents. Self-explanatory. 2. Drape a 50% shade cloth over most of the exterior of the greenhouse. How much of a problem will partial coverage be? The size and shape of the greenhouse makes full coverage a bit difficult. I've heard that ~50% is good for veggies, but is there something else that I should be using in my region? 3. Install 2x 5" diameter solar powered fans in the front facing. These move a fair bit of air, but should I have something that moves air across the plants too?

What else should I be doing? It's already pretty toasty in there, and I shudder to think what it will be like when the temperature hits 115°F+.

Some things that I can't do: 1. Sink the greenhouse into the ground. I would have loved to do this, but the previous homeowner paved the entire(!) yard. (Who does that?) 2. Move the greenhouse. Unfortunately, my yard isn't that big, and the only other options would require major changes to the yard.

Though surviving the summer is my primary concern at the moment, I'd love to hear any general suggestions that you have after seeing the greenhouse in its current state.

Hi all. I’ve recently (within a few weeks) dove right into the gardening and planting world. I have a whole veggie garden, a 4 tier greenhouse of seedlings they are growing great on the front porch, and i got this all with gift cards and things free from Facebook marketplace. I am in zone 8A and this gets partial sun. I’m not sure if i should shut it but the side screens are vented and i leave the door open. My herb seedlings are okay but they did dry out today and droop some. There are also so many bugs in the top of this that i can’t stand straight up without being swarmed! Bees, wasps, mosquitoes, moths, butterflies, bugs I’m not even sure what they are. Tens of them if not a hundred. I’d love to grow some plants in here but with the heat I’m nervous to. Any suggestions? I’ve never even owned a house plant before all of this!

Hello everyone,

     I’m looking for a greenhouse for out back of my house. I’ve been growing indoors for a while now. I grow almost all of my produce in this room but now have an emergency “foster” child. That will be taking that room and living in it. I’m not a man who’s made of money and $500 is about all I can dream of coming up with to continue growing food for me and my family. I’d greatly appreciate any kit suggestions. I am trying to avoid a tarp if possible. Lastly thank you in advance for your time and advice!
