The Greenhouse Reddit

Greenhouse - a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.[3] These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external ambient temperature, protecting its contents in cold weather. Wikipedia: greenhouse

What material is best for a lean-to type greenhouse here?

I’m considering putting a greenhouse as a lean-to against this compost barn. It runs East and West and is level because it had a 20’ lean-to running the distance at one point. It’s about 80’ long but I could start with maybe 30’ and grow each year or two. I plan on making a basic would pole structure but I’m not sure what covering would be best?? I’m in the South zone 8 and I’m looking to control the environment and lengthen the growing season. Any help would be appreciated!

Bicarbonates in water

This is my 2nd year to grow. I struggled a bit with a few species but wrote it off until my chrysanthemum crop started to die and so I sent my water off for analysis and got the results back. I have high bicarbonates. I’m a smaller grower (30 x 60 foot GH) so does anyone know an inexpensive way to solve my problem or that could maybe point me in the right direction? Google isn’t much help, I feel intimidated about the scientific talk of injecting acid or an even RO system.

I’m sick and let my greenhouse get to 120* plus with seed trays, should I re-sow?

I have a tiny greenhouse I use for starting seeds cause it’s still a bit cold in the ground, but I’m in southern ca(10a) so we’re getting plenty of sun. Usually I put the cover down at night and unzip it in the morning, but I’m sick and slept in. When I got up around 10:30 the temp on the mercury thermometer was maxed out o.o

One tray I just started, the other is a couple weeks old with some sprouts, and a couple already have seedlings that look like they’re doing okay. I’m mostly worried about what hasn’t germinated yet. Did I bake the seeds or will they still germinate? Any advice appreciated.

Ps i want to cut ventilation holes in the sides but haven’t because my partner disagrees and wants to keep the “structural integrity” or something, lol. Pps ignore the weeds we got lots of rain 😂

Beginning on a budget

I want to start growing edible plants in a greenhouse beginning this spring. I am a stay at home mom that works part time so I have considerable time to devote to the project, however my family is considered “below poverty level”, hence my desire to contribute to our dinner table year round. I am looking for any and all advice for doing this as inexpensively as possible. (I read somewhere there may be a government program for low income individuals where they will send you the materials?) I also would like to do so with as little space as possible as I rent a fixed third wheel camper on someone else’s property. I have the opposite of a green thumb, I’ve been known to even kill cacti, so no amount of information is too much. (I will also have the help of my husband who has years of experience in landscaping, just very little knowledge of how to grow food.) Thanks in advance for your help!

Sloped roof orientation?

I just bought plans to build my new greenhouse like this image. So my question is does it matter which direction the roof is oriented? I'm building in my backyard and the back of my house is north facing. I'd rather have the tall side towards my house and wasn't sure if this was possible?

Did I kill my seeds with overheating?

I just got my greenhouse for Christmas so I am new to controlling temps. I started tomato and pepper seeds on January 31st. Recently there has been 2-3 times where the internal temp got above 100 during the day because I didn't monitor the app that displays my monitor, or I wasn't home and I was unable to go open the greenhouse and ventilate it. Did I kill my seeds? Will they still sprout at all?

I have a monitor to turn on a heater and heat mats when the temps get below a certain degree, 73, but I don't have a way to open a window unless I do it manually.

Water butt

Hello everyone I have recently moved into a new home that has a greenhouse, it has a water butt at the top of the water butt is a tap? How am I supposed to get the water out of the water butt if the tap is at the top? Sorry for being an amateur but it doesn’t seem to make any sense to me? There is no pipe attached to the tap

Cabinet Greenhouse troubles: Help! Unhappy herbs & little gnats

Hiya! I posted a bit ago having trouble with soil fungus; that seems to have cleared up, and I've turned down the humidity in the greenhouse and added another fan (still working on mounting the fans higher so that the air blows more evenly to the other side of the greenhouse). But, I'm noticing a bunch of gnats flying around in there, and the herbs do not look happy (although my tropicals are thriving). Some of the herbs also have small white spots on the leaves, which I'm thinking are maybe mites? Any idea what these issues could be/advice on solving them before my herbs die? This is my first time trying herbs other than a pot of basil in the window, so this is all very new! Images attached.

White spots on leaves

Plants are looking dry, although I've been watering them (possibly not enough but I'm afraid to over-water). Small gnat on the wall, hard to see but bigger than a spider mite or fruit fly.

Rosemary also seems to have some small white spots and browning tips.

Suggestions for heater and fans for a 10X12 polycarbonate greenhouse

I would love suggestions for what type heater to use in our 10X12 foot greenhouse. We are having electricity installed next week and want to start seedlings and we are in zone 6B so know we will need heat for nights to keep the seeds warm. I'm also wondering if anyone has ideas about how many/what size fans I might need in this space.

Greenhouse growing zone 8a - when to seed start

I am new to green house growing (long time veg gardener). Do you start your seeds in a greenhouse the same time as you would if your were using in an in-home grow light set up?

Greenhouse Repair Help!

Hey reddit! I work on a nonprofit farm that helps adults with disabilities. I've been running the horticulture/agriculture program for 2 years and starting to work on learning about my greenhouse. It is 50ft long 32ft wide heated greenhouse that was built about 10 years ago. I've been trying my best to research all things greenhouse but what are some recommended films or the best way to go about putting new film on a greenhouse? I couldn't find anything on the company that put in the original film (AT Films) We are in Zone 6

how to keep your greenhouse warm

I am planning on building a greenhouse for tropical fruit plans. My plan is to use cattle panels for its construction and use swivels on the sides to open it during the hot summers. My region posses a really unpredictable weather..however only 2-3 months a year is when I will see the most coldest temperatures. my plan is to use natural sources of heat to keep my greenhouse hot and humid. Things like a compost pile next to the greenhouse, black water jugs and perhaps a propane gas portable heater. I would like to avoid using the later. During my research I came across a underground oven that many parts of Mexico people use to cook meats. I was just wondering if have anyone thought about this, and how save do you think it could be. Would it be warm enough to maintain the greenhouse warm enough for the plants? what are your thoughts?

Greenhouse for Desert Plants

Hello,

I live in zone 7b and will likely move to a 7a zone and have interest in building a greenhouse or something similar to grow desert plants. I have tried googling it, but I can’t seem to find anything on how to at least start it or everything I’ll need to consider to make sure the air stays warm/ hot and dry all year.

Appreciate any help!
