Hi, I would like to power automatic roll-up sides with a solar panel and battery. Is anyone doing this and what is your setup? Ideally I would like to have everything operate off of 24VDC as this is what the roll-up side motors take, however most controllers I've seen accept only 110VAC. My ideal situation would be wiring a 24VDC solar panel to a 24VDC battery which would then feed directly (without an inverter) into some kind of a controller capable of operating in stages (i.e., if ventilation was required, the roll-ups would operate a certain set amount of time and then pause for a certain set amount of time before re-evaluating the temperature; this way the roll-ups would not yo-yo up and down all the time). Or can someone talk me out of this setup? Maybe I should just setup a 48V solar system with an inverter that could then be used to power other equipment in the future?

Does anyone have good sources of information (books, articles, websites) on the history of greenhouses? I’d especially like to know about the period of home architecture where greenhouse additions were built into homes, and when they faded out.

Thank you!

I live in the US plant hardiness zone 6a/6b. It usually will only dip into the low teens a few days each year but some years there is the random day or two that can dip into the -10f temps with wind chills. Lately winters have been pretty mild though, with temps in the 20s or 30s and it doesnt seem to snow much here compared to when I was a child.

I currently have 3 large trellised 20g pots with 6ft dragon fruit plants on castors in my heated garage. Dragon fruit grow best in temps ranging from 50f to 85f but can handle higher temps but might not flower/ set fruit in extreme heat, and they can handle temps in the low 40s but will die when temps approach freezing.

I want to get a greenhouse this spring, something around 12ftx8ft and will anchor it to my south facing concrete patio out back. Im looking at the 2 ply polycarbonate style greenhouses which should add an insulation factor since my winters can get pretty cold. Not sure yet if I will buy a greenhouse in a box or build my own framing and use 2 ply polycarb panels.

Im researching using black rain barrels filled with water for a thermal heat mass that will collect heat during the day and put out warmth during the night. Might add a heater or two to the barrel. If this doesnt keep the temps high enough I would look into other heating options.

Ive never had a greenhouse though and wonder if I should just use it to house the plants in the colder spring and fall seasons, bringing them out in the full sun durring the summer, or if I could/should grow them inside the greenhouse year round? In the dead of summer its usually mid 90s and humid here so wonder if it will get too hot to grow them in the greenhouse in summer?

I know probably noone here grows dragonfruit but also know you guys have greenhouse experience and dragonfruit growing should be similar to succulent plants or other fruit bearing sub tropical plants.

Any suggestions?

Thanks

Hello, I'd like to ask you to help me with a project. I'm a master's student in entrepreneurship and I need your help to carry out an in-depth study for a group project. Could you help me by giving me some of your time and completing this questionnaire? We'd like to target people with a passion for gardening.

I have a crested gecko and its light are connected to an analog timer that switches them on/off. Will a misting system connected to the "Inkbird Humidity Controller" work the same way? When the Inkbird reads that the tanks humidity is below a certain level, will it turn on on the misting system?

Last year I put an inflatable tub in and moved all of my potted plants from he front porch in there before the first freeze. My thinking was that the plants (Impatience, salvia, vinca, fuchsia, geraniums, begonias, etc.) would survive a few weeks longer and I would get to enjoy the flowers for a few extra weeks.

What ended up happening was everything stayed in full bloom and when springtime came, they all got moved back to the front porch. This is Oregon so an impatient is an annual that might get a foot tall and foot wide by winter. Mine were as big as shrubs this year! One pot was at least four feet wide and three feet tall-all covered with flowers!!! That poor thing finally collapsed under its own weight.

Any suggestions for plants that would flourish under such conditions? The impatiens were amazing but collapsed. I'm wondering if there is something similar-lots of flowers, doesn't get huge, that would transition well from porch to greenhouse and back. (the greenhouse gets blazing hot in august so I have to move things out or they get melted-even with the doors open it is on a cement pad that gets reflected heat-so--a plant that can survive heat would also be helpful.

Also--by February I had a pretty bad aphid attack going. I didn't want to use pesticides. This year a pretty honking house spider was in one of the plants that got moved back in. It is huge and terrifying but I figured if it would eat aphids so I told it to go live over in the corner. It refuses to listen and is directly over the hot tub. Anyone ever winter over a spider like this? Will I need to get some fruit flies or something for it?

Sorry for all the questions. My greenhouse went from all spring use with seeds, emptied in the summer and winter to this tropical, year round, VERY moist growth space that is magical (it is in FULL bloom still) but has such a flip flop of environments (moist cold tropical to hot tropical to scorching dessert and back...) (I am going to try a greenhouse cover this august).

Hey guys. I'm at student at West Virginia University and I'm doing some market research to see what people's thoughts are on hemp plastic. If you could please take this for me so l can complete my final project🙏🏼💚

We're looking to get a greenhouse kit, hopefully 16x16 or even 20x16. We'd like it be a rather permanent fixture and last 20-30 years. Would it be worth opting for glass, or is polycarbonate good enough quality? We have very sunny summers and very cloudy octobers-aprils

So I have a garden shed in my yard & I have plans! I'm going to take an end wall out and frame in a small area (8x4 ish) that I'll be turning into a greenhouse. I have access to some old windows from a house demo - wood frames in ok condition, decent glass quality. I can frame it with 2x4's pretty easily.

I'm not sure what to do about the roof though. The windows were from a double hung installation so the frame is pretty substantial - if I use them the rain will collect in them which I suspect will lead them to rot in short order.

I don't really want to use the plastic corrugated stuff, but I'm not finding anything else suitable. Any ideas out there?

Hi!

My team and I are building an AI-powered platform . We're in the early stages of development and really want to make sure our tool addresses the specific needs of greenhouse owners.

We'd be incredibly grateful if you could spare just 2-3 minutes to answer a few quick questions. Your insights are invaluable as we work to create a truly helpful resource for the greenhouse community.

1. Can you walk me through the last time you had a plant health issue in your greenhouse? (What happened? What did you do? How did it turn out?) Focus on concrete examples.
2. What's your current process for identifying and treating plant problems? (Tools, methods, resources)
3. Thinking back on past plant health issues, have you ever investigated or tried any tools or services specifically designed to prevent or manage these issues? What was your experience like?
4. What are the biggest time or money sinks when it comes to dealing with plant health in your greenhouse?
5. If you could wave a magic wand and fix one thing about managing plant health in your greenhouse, what would it be?
6. What kind of data or reports would be most useful to you in making better decisions about plant health?

Thank you so much for your time and insights! Your feedback is incredibly helpful . We appreciate your help!

Hi everyone,

Hope my question is okay.

I was wondering if any of you have knowledge about sensors for greenhouse which can measure and graph the current and historical temperatures and humidifier for custom time periods. It is to be used for winter storage and general monitoring of plants.

If you are familiar with the airthings brand of wave sensors etc. then they exactly do this, but it is not rated for outdoor use.

The greenhouse is my in laws and it has no wifi coverage nor electricity, so far my best bet is still the airthing sensor and just hope it survives, but I would prefer to gift them something made for this purpose.

This greenhouse I have is great for propagating from cuttings, by not letting the leaves dry out. In fact, I can leave bigger leaves on the stems which seems to make the process faster. However, the greenhouse starts to develop powdery mildew and these little mildew tentacles as can be seen at the top of the stick in the photo.

By opening the vents and airing it out more, I can slow down the mildew, but it also makes it dryer in there and some leaves start to shrivel up. It seems like I have to choose between having mildew and a better outcome for my cuttings or no mildew and slower cutting propagation.

Any tricks to help? I was thinking about getting a UV light that can kill the mildew but help the leaves grow. I'd have to install it inside the dome since the plastic might filter the UV out. I also don't know what wavelength of UV would kill the mildew but be harmless to me and the plants.

I'd rather not do chemicals unless it's something non poisonous.

Thank you.

Australian wildflower grower here mostly Proteas and Leucadendrons with some foliage and annual flower crops.

Looking to expand into polytunnel cut flower production for perrenials possibly roses or carnations.

We have plenty of machinery and experience for outdoor work, a packing shed and will use automated watering amd climate control as well as existing labour for harvest.

The question is - how much area can one person reasonably maintain?

Hello! I am looking for heater recommendations for my small hobby greenhouse. It is like 20'x15', and I will be using standard power. I see so many options I don't know where to start.

Even just brand recommendations or specifics to look out for would be great.

Hi,

I'm brand new to gardening so pardon me if these are dumb questions.

I'm in Zone 9B and the nights seem to be unusually cold. I'm thinking of setting up a greenhouse. I am NOT handy so will have to buy one.

1. Should the greenhouse be closed at night? I see greenhouses on Amazon & Walmart that seem to have no doors to shut! Is there any site that sells pre-constructed green houses that I could purchase?

2. I am especially concerned about my banana and neem plants. They're babies and I'm terrified about how they'll do in the winter. Does anyone have any tips raising tropical plans in this Zone (9B)? How can I make sure my plants stay warm at nights? Should I use a portable heater for the nights? If so, what brands would you recommend?

Please help. TIA.

Hi, we are looking to heat a relatively small greenhouse that is located in a badly isolated warehouse. Last year it froze (even inside the warehouse), so we want to prevent this happening again as we have a lot of houseplants ( mostly philodendron, monstera, ficus but also some tropical plants). Gas heating is not an option.

We are located in the Netherlands
