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

Question for those that have their misting system connected to an "Inkbird Humidity Controller"

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?

I put an inflatable hot tub in my 10x12 unheated greenhouse. It has opened up a world of possibilities-Any tropical-like plant suggestions?

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).

Is glass worth it?

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

DIY roof ideas

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?

Greenhouse sensor and measurement of temperature and humidity

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.

Tabletop greenhouse is starting to develop mold/mildew (and smells like it)

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.

BRAND NEW to gardening in Zone 9B - please advice

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.

Heating a greenhouse

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

Greenhouse Gardening for Beginners - Where to Start?

Starting a greenhouse garden might seem daunting, but with the right guidance, it becomes a manageable and rewarding task. The key is to begin with a clear plan and understand the basic requirements of your plants. By doing so, you'll be able to provide the ideal conditions for growth and productivity.

Most importantly, remember that every plant has unique needs. Therefore, your first step should be research. Learn about the plants you're interested in growing and their specific requirements in terms of temperature, light, and moisture. This knowledge will guide you in setting up your greenhouse environment effectively.

Choosing the Right Greenhouse

Before you can start planting, you need to select the right greenhouse. This decision will depend on several factors, including your available space, budget, and the climate in your area. Let's break down the considerations to help you make an informed choice.

Deciding on Size and Structure

The size of your greenhouse will largely depend on the space you have available and what you plan to grow. A small greenhouse is ideal for beginners, as it requires less maintenance and is easier to manage. However, if you have big plans, a larger structure might be more suitable.

Consider the layout of your garden and how a greenhouse will fit into it. Think about future expansion as well. You might start small, but as your gardening skills grow, you may want to increase your planting area.

Materials and Durability Considerations

Greenhouses come in various materials, each with its own pros and cons. The most common materials are glass, polycarbonate, and polyethylene. Glass is traditional and offers excellent light transmission but can be fragile and expensive. Polycarbonate is more durable and offers good insulation, making it a popular choice. Polyethylene is cost-effective and lightweight but may need replacement more frequently.

When choosing materials, consider the durability and maintenance requirements. If you live in an area with harsh weather conditions, opt for a sturdier material that can withstand the elements. For more insights, check out this guide to greenhouse gardening.

Setting Up Your Greenhouse Environment

Once you've chosen your greenhouse, the next step is setting up the environment inside. This involves regulating temperature, ensuring proper ventilation, and optimizing light conditions. Each of these factors plays a critical role in the health and growth of your plants. For more information on best practices, explore optimized IoT greenhouse environments.

Temperature Regulation

Temperature control is vital for a successful greenhouse. Plants have specific temperature ranges in which they thrive, and maintaining these conditions will boost their growth. Use a reliable thermometer to monitor the temperature inside your greenhouse.

If you live in a colder climate, consider investing in a heater to keep your greenhouse warm during winter months. Conversely, if you are in a hot climate, ensure your greenhouse has adequate shading and ventilation to prevent overheating.

Managing Soil and Planting Beds

Soil is the foundation of any successful greenhouse garden. The quality of your soil will directly impact the health and productivity of your plants. Therefore, it's crucial to invest in good quality soil that is rich in nutrients and has excellent drainage. A well-balanced potting mix often contains peat moss, perlite, and compost, providing the necessary nutrients and aeration.

When setting up planting beds, ensure they are raised to facilitate better drainage and aeration. Raised beds also make it easier to manage and maintain your plants. Regularly check the pH level of your soil, as different plants have varying pH requirements. You can adjust the pH by adding lime to raise it or sulfur to lower it, depending on your plants' needs.

Selecting the Best Plants for Your Greenhouse

Choosing the right plants is crucial for a successful greenhouse garden. Start with easy-to-grow varieties that are well-suited to greenhouse conditions. This will give you a solid foundation and build your confidence as a gardener.

Vegetables Suitable for Beginners

Some vegetables are particularly well-suited for greenhouse growing, especially for beginners. These include tomatoes, lettuce, cucumbers, and peppers. They thrive in the controlled environment of a greenhouse and can provide a bountiful harvest.

Vegetables in Greenhouse

Tomatoes, for example, love the warm temperatures and can be grown almost year-round in a greenhouse. Lettuce is another great option as it grows quickly and can be harvested multiple times. Cucumbers and peppers also do well, providing fresh produce throughout the growing season.

Fruit Options and Their Requirements

Growing fruit in a greenhouse can be incredibly rewarding. Strawberries, melons, and figs are excellent choices for beginners. Strawberries are relatively easy to grow and can produce fruit over a long period. Melons require a bit more space but thrive in the warm, humid conditions of a greenhouse.

Figs, on the other hand, need a bit more attention. They require a well-drained soil mix and should be watered sparingly to prevent root rot. With proper care, these fruits can provide a delicious addition to your greenhouse garden.

Herbs and Flowers to Consider

Herbs and flowers can add beauty and fragrance to your greenhouse while providing culinary and medicinal benefits. Basil, parsley, and mint are easy to grow and can be harvested regularly. These herbs thrive in the controlled environment of a greenhouse and can be used fresh or dried

Flowers such as marigolds and petunias can also be grown in a greenhouse. They add color and can help attract beneficial insects. Besides that, they can make your greenhouse a more pleasant and enjoyable space to spend time in.

When selecting herbs and flowers, consider their growth habits and requirements. Some may need more light or space than others, so plan accordingly to ensure all your plants have the room they need to flourish.

Essential Tools and Supplies

Equipping yourself with the right tools and supplies is key to maintaining a healthy and productive greenhouse. These tools will make your gardening tasks easier and more efficient, allowing you to focus on nurturing your plants.

Invest in quality tools that are durable and designed for greenhouse use. This will save you time and effort in the long run, as well as improve the overall health of your plants.

Must-Have Gardening Tools

Every greenhouse gardener should have a set of essential tools. These include a trowel for planting, pruning shears for trimming, and a watering can or hose with a gentle spray nozzle. A hand fork is also useful for loosening soil and removing weeds.

Additionally, a soil thermometer can help you monitor soil temperature, ensuring your plants are in the optimal growing range. A hygrometer is another valuable tool, allowing you to measure humidity levels and adjust them as needed.

Recommended Greenhouse Accessories

Besides basic tools, there are several accessories that can enhance your greenhouse gardening experience. Consider installing a shade cloth to protect plants from intense sunlight and prevent overheating. A ventilation system, such as fans or vents, is also essential for maintaining air circulation and temperature control.

Heating mats can be beneficial for germinating seeds, providing the warmth they need to sprout successfully. Automatic watering systems are another great addition, ensuring your plants receive consistent moisture without the need for constant monitoring.

Safety Equipment and Measures

Safety should always be a priority in your greenhouse. Wearing gloves can protect your hands from cuts and irritation, while safety goggles shield your eyes from debris and chemicals. Always store tools and supplies in a safe and organized manner to prevent accidents.

Be cautious when using fertilizers and pesticides, following all safety instructions and wearing protective gear as needed. This will help ensure a safe and healthy environment for both you and your plants.

Monitoring and Maintaining the Greenhouse

Regular monitoring and maintenance are essential for keeping your greenhouse in top condition. This involves checking for pests and diseases, adjusting environmental conditions, and ensuring your plants receive the care they need.

Pests and diseases can quickly ruin your greenhouse garden if not managed properly. Regularly inspect your plants for signs of infestation, such as discolored leaves or unusual spots. Insects like aphids, spider mites, and whiteflies are common culprits, so keep an eye out for them.

If you spot any pests, act quickly. Remove affected leaves and consider introducing natural predators like ladybugs or using organic insecticides. Diseases often result from high humidity and poor air circulation, so ensure your greenhouse is well-ventilated to prevent fungal growth.

Regular Maintenance Tips

Regular maintenance is key to a thriving greenhouse. Keep your greenhouse clean by removing dead leaves and debris, which can harbor pests and diseases. Regularly wash windows and panels to ensure maximum light penetration for your plants.

Check and calibrate your tools and equipment, such as thermometers and hygrometers, to ensure they provide accurate readings. Consistently monitor the health of your plants, adjusting care routines as needed to keep them thriving.

Seasonal Care and Adjustments

As seasons change, so should your greenhouse care routine. In winter, insulate your greenhouse and use heaters to maintain optimal temperatures. In summer, increase ventilation and use shade cloths to prevent overheating.

Adjust your watering schedule according to the season. Plants may require less water in cooler months and more during warmer periods. By adapting to seasonal changes, you can ensure your plants continue to thrive year-round.

Best Practices for a Successful Greenhouse

Success in greenhouse gardening comes from understanding your plants' needs and creating an environment that supports their growth. Always prioritize monitoring and maintaining the conditions within your greenhouse, as this is crucial for plant health.

Building Lean-To Greenhouse - Questions

So I have the plans that I created. It will be 153" wide, 78" deep, 8' tall (short side of the roof) and 11.75' tall (tall side of the roof) which gives me a roof angle of 30deg. I get a lot of snow where I live but there are a decent amount of sunny days in between to help melt it off. During a good winter, I can have 3-4 ft of snow outside. I don't want to roof to cave in. I want all of the snow to slide right off. The internet said that 15deg would it but I don't really see how that's possible.

My idea is to frame with 2x4s and use polycarbonate panels for the walls. I want the roof to be polycarbonate to let more light in but I'm worried that it's gonna crush under the pressure of snow. Maybe I just double up on beams?

I can put a heater in there to help out with the cold. I live in Flagstaff, AZ. Winter nights are normally anywhere from 5-15deg. I've seen it hit -15 before, but it's not common.

Any advice would be much appreciated.
