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

This is my second year with a greenhouse last year I struggled with keeping it warm enough to not kill off the plants. I've been doing some reading on bubble wrap insulation and water barrels for heat. Any pro tips? Thanks in advance!

Would you put pavers on top of this gravel or spray it with glue? I can’t decide

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.

By staying proactive and attentive, you can prevent problems before they arise and ensure your greenhouse remains a thriving space for plant growth.

Routine checks will also help you identify any issues early on, allowing you to address them promptly and effectively. This will save you time and effort in the long run and lead to a more successful gardening experience.

Keeping an Eye on Pests and Diseases

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.

Experiment with different plants and techniques to find what works best for your specific setup. Don't be afraid to try new methods or seek advice from other gardeners. The more you learn, the more successful your greenhouse will become.

Efficient Watering Techniques

Use a drip irrigation system to provide consistent moisture without overwatering. This method saves water and ensures your plants receive just the right amount.

Drip irrigation is an excellent way to maintain consistent moisture levels in your greenhouse. This system delivers water directly to the plant roots, reducing evaporation and ensuring efficient use of water.

Consider using rainwater collection systems to provide a sustainable water source for your greenhouse. This not only conserves water but also reduces your gardening costs.

Always water your plants in the morning to prevent fungal growth and ensure they have enough moisture throughout the day.

Fertilizing Your Plants Effectively

Fertilizing is essential for providing the nutrients your plants need to grow. Use a balanced fertilizer that contains nitrogen, phosphorus, and potassium. Apply it according to the specific needs of your plants, as over-fertilizing can harm them.

Organic fertilizers, such as compost or well-rotted manure, are excellent options for greenhouse gardening. They improve soil structure and provide a slow-release source of nutrients.

Redwood framed, 30" Tudor door on customers foundation and knee wall. Get yours today, and live your dream. Note that the customer just finished the build and is getting ready to move plants in.

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.

We are looking at getting a PE greenhouse like the picture. We're in zone 8 so doesn't get too cold at night, but I'm trying to keep from having to bring inside a handful of plants (yucca cane, bearss lime, majesty palm, money tree). Obviously I wouldn't expect a thin greenhouse like these to help with below freezing temps, but would something like these be enough or even make a difference when the night time is only high 30s/low 40s?

If not, is there an easy way to warm the greenhouse at night without burning it/our house down? The plants so far have been fine with mid-high 40s (a couple nights, most nights 50+), so we're trying to accomplish at MOST a 10° difference at night.

im looking for a place to find ideas or plans/books for building a custom lean against greenhouse on a large slab of concrete in my back porch, its against a ranch house. i wanted to make custom slabs of glass and or durable greenhouse material. any information would be appreciated

We have an original Lord and Burnham Blue Ribbon Greenhouse in the back yard of our house in Atlanta, GA. It‘s 40’ L x 20’ wide and was originally built in the early 70s. When we bought the house in 1998, it was being used primarily as a storage shed and was in need of work. We restored it in phases. The first round we did ourselves not long after we moved in. In 2011 we did a much more substantial restoration with the help of B&B Greenhouse — a local company that built it originally but has sadly gone out of business. The owner (whose father built the greenhouse originally) searched all over the US for parts, which was difficult even then, but was able to get what we needed. We are now selling the house and moving. The new owners may not want the greenhouse and we would be very sad if they tore it down. We were wondering if there is anyone that would be interested in dismantling the structure for the parts. We appreciate any feedback on what to do or any contacts that might be of help. Cheers.

I'm just wondering if these flimsy plastic ones actually work; they're much cheaper than polycarbonate atleast.

Good morning All,

I am an agriculture teacher and have recently come into possession of a massive greenhouse that has not been used in over a year. I’d like to get it running as soon as possible for my classes but I don’t know where to begin. It is a “sun-mate” greenhouse with kool pads, fans, heating cooling system, etc. (I can post photos of systems)

I have never had such a complex greenhouse and nobody on campus knows how to use it so I have been reading all the manuals. What is the first step? (Besides cleaning)

Please help!

Thank you

Hi! I’m brand new to green houses and I’m wanting to keep mine warm all winter long to keep live stock and plants in. I plan to get a tent green house that is 20ftx10ft as this is the only decent sized one that fits my budget right now. What are some energy and cost effective ways to heat it during the dead of winter that you would suggest? I’ve looked into electric and propane but I really want something cost effective. I’ve been looking into getting a diesel heater and putting homemade diesel in it and was also wondering if anyone has tried that? Any natural ways? Looking to keep it around 50 degrees in dead of winter. Thank you!

hello, i am an architecture student designing a hydroponic farm/housing project, and i am working to familiarize myself with climate systems within greenhouses to ensure proper conditions.

a couple of questions:

• do you install your cooling pad right next to your entry vents?
• can you rig the system to send the water to naturally circulate back up to the top of the pad? or does it need to be manually cycled?
• i live in atlanta, georgia - humid climate, but i still hear these walls can cool your air by around 10 deg F when relative humidity is around 60%. are there other cooling methods you would recommend to pair evaporative cooling with for more humid climates in the summer?

thanks so much! any feedback or referral to quality sources would be immensely appreciated!

Around 1 my greenhouse peaks at 100-105 degrees, what can I do to help bring this down?

My greenhouse (4.5m²) is on a wooden deck, which is fine in summer because it allows some air flow from beneath. But it is terrible in winter.

I live in Norway, so nothing will be growing there during the winter, but I am overwintering a lot of plants. I won't be heating it in any way, I just want to keep as much of the cold out as possible.

I have been trying to google some solutions that won't be too expensive, so I came here to see if you have any ideas and to get your input on my ideas.

My thoughts: 1: using a tarp to cover the floor? It won't insulate much, but will keep most of the wind out?

2: foam boards, or layered sleeping mats to insulate (And maybe with a tarp over/under them?)

3. A few articles said to use bubble wrap on the floor?

I am doing that around some plant pots that need extra protection, not sure about using it on the floor though?

4. Thermo foil (Buble wrap covered with aluminumfoil). Said to insulate and be reflective. (See biltema.no -> "termofolie" for more info)

Which alternative or combination of alternatives would you try? Or do you have any other ideas?

Thank you in advance!

I have had this poor thing for I'd say 5 years or so, after all those years of freezing winters and relentless wind blown uv intense summers 1 autumn/winter in a greenhouse and I am about to see my first flowers ever.

Looking for Advice on Two Greenhouses

Hi everyone! I’m looking for some advice on choosing between two greenhouses, and I’d love to hear your thoughts.

1. Option 1:
   • Price: Free
   • Condition: Not dismantled, but the door is currently not attached. We couldn't find any brackets to reattach the door. Does anyone know if these brackets are easy to buy?
   • Side Note: If I can’t get the door to fit, do you think it’s worth keeping this greenhouse for spare parts?
2. Option 2:
   • Price: £50
   • Condition: Already dismantled. I’m a bit concerned it might be harder to put back together.

Which one would you go for? Any advice on the door brackets or reassembling a dismantled greenhouse would be really appreciated! Thanks in advance!

Option 1

Option 2
