5 Great Places To Look For Greenhouse Kits on Sale

Here are 5 great places to look for greenhouse kits so that you get the best deal.

#1: Facebook Marketplace

Facebook Marketplace is an excellent place to hunt for greenhouse kits, especially if you’re okay with buying a used one or finding a great local deal on a new kit. Sellers range from everyday people clearing out their garages to local businesses offering discounted new products. Here’s why it’s a smart option:

• Great for Local Deals: The biggest perk of Facebook Marketplace is the ability to find deals in your local area. Since you’re dealing with nearby sellers, you can often arrange to pick up the kit in person, avoiding the hassle and cost of shipping something as bulky as a greenhouse.
• New & Used Options: You’ll find both new and used greenhouse kits here. People often sell kits that were barely used or never assembled, which means you can get nearly new equipment at a significant discount.
• Room to Negotiate: Unlike big retailers, Facebook Marketplace allows you to negotiate directly with the seller. This means you might be able to lower the price even further, especially if the seller is eager to offload the item.
• Quick Turnover: Things move fast on Facebook Marketplace, so if you see a deal you like, it’s best to act quickly. However, that also means new listings pop up all the time, so it’s worth checking regularly.

#2: Craigslist

Craigslist is another popular platform for finding used greenhouse kits at discounted prices, especially from individuals who are looking to sell quickly.

• Deep Discounts: Craigslist is known for great deals, especially if the seller is trying to clear out space or move. Since it’s a classifieds site, you can often find heavily discounted greenhouse kits that might be older models or slightly used.
• Local Pick-Up: Like Facebook Marketplace, Craigslist is location-based, so you can search within your local area to find deals nearby. The benefit here is no shipping costs—you can arrange a time to pick up the greenhouse in person.
• Condition Check: One big advantage of buying through Craigslist is that you get the chance to see the kit in person before committing. This lets you check the condition, verify that all parts are included, and make sure it fits your needs.
• Buyer-Seller Negotiation: Craigslist gives you a lot of room to negotiate. If the seller is motivated to move the item quickly, you could score a significant discount by offering a lower price.

#3: eBay:

eBay is one of the go-to platforms for finding both new and used greenhouse kits, with a twist—you can either buy directly or enter an auction to bid for the best price.

• Auction-Style Deals: eBay’s auction format can be a fun way to snag a deal if you’re willing to monitor listings and place strategic bids. Sometimes, you’ll find greenhouse kits at surprisingly low prices if there’s little competition for the item.
• Buy It Now Options: If you’re not interested in waiting for an auction to end, eBay also offers “Buy It Now” listings where you can purchase items immediately. This is a good option if you find a price that’s already discounted and want to secure the deal without the hassle of bidding.
• New & Used Kits: You can find both brand-new greenhouse kits from retailers and gently used ones from individual sellers. The selection is often larger than local classifieds because you’re shopping from sellers across the country (or even internationally).
• Shipping Considerations: Keep in mind that some sellers offer free shipping, but for larger kits, shipping fees can add up. Always factor in the shipping cost when deciding if it’s truly a good deal.

#4: Local Garden Centers and Hardware Stores:

Your local garden centers and hardware stores can be treasure troves for finding greenhouse kits on sale, especially if you catch them during the right season.

• Clearance and End-of-Season Sales: Garden centers and hardware stores often hold clearance events at the end of summer and early fall when they’re trying to clear out seasonal stock. This is a great time to find greenhouse kits at reduced prices.
• In-Store Exclusives: Many stores offer in-store discounts or clearance sales that aren’t advertised online. So, if you have time, it’s worth visiting in person to see if there are any unlisted deals.
• Support and Assembly: Buying locally has the added benefit of being able to ask store employees for advice on selecting and assembling your greenhouse kit. Some stores even offer installation services or helpful tips that you wouldn’t get with an online purchase.
• Local Loyalty Programs: Some garden centers and hardware stores have loyalty programs or special promotions for regular customers. Signing up could give you early access to sales or discounts, helping you save even more.

#5: Big Online Retailers:

When it comes to convenience, big online retailers like Amazon, Walmart, and Home Depot offer a massive selection of greenhouse kits, often at competitive prices. Here’s how to make the most of these platforms:

• Wide Selection: These retailers carry a huge variety of greenhouse kits, from small hobby-sized models to large commercial-grade kits. Whether you’re looking for a basic starter kit or a top-tier model, you’ll likely find it here.
• Regular Sales: Big retailers run sales events throughout the year. Look out for discounts during major shopping holidays like Black Friday, Cyber Monday, Memorial Day, and Labor Day. They often drop prices significantly during these times, making it a great opportunity to save.
• Sign Up for Alerts: Many retailers allow you to sign up for email notifications or sale alerts. This way, you’ll be the first to know when greenhouse kits go on sale.
• Free Shipping Deals: Some online retailers, especially Amazon with Prime membership, offer free shipping for large items. Given the size of most greenhouse kits, this can save you a lot of money compared to buying from smaller retailers where shipping can be costly.
• Customer Reviews: One huge advantage of buying from big online retailers is the wealth of customer reviews. Before purchasing, you can read feedback from other buyers to make sure you’re getting a quality product.

The Benefits of Buying Greenhouse Kits On Sale

Taking the path of getting greenhouse kits on sale carries a few key benefits:

Save Money:	The most obvious benefit is saving cash! Greenhouse kits can be pricey, so grabbing one during a sale means you’re spending less for the same product. That extra savings can go towards other gardening supplies or upgrades.
Get More for Your Budget:	When you buy on sale, you can often afford a higher-quality kit or a bigger size than you normally would. This means you get better features—like stronger materials, better ventilation, or extra accessories—without breaking the bank.
Seasonal Deals:	Many sales happen at the end of the gardening season or during big shopping events (like Black Friday), so it’s the perfect time to buy when prices drop. These discounts can be significant, especially if you’re flexible with timing.
Start Gardening Sooner:	Sales give you a chance to get started with your greenhouse earlier than you might have planned. You don’t have to wait until you’ve saved up more money or until the perfect moment—sales make it more affordable to dive in.
Avoid Future Price Hikes:	If you buy during a sale, you lock in a lower price, which can be really helpful if prices go up later. Getting a deal now could save you from paying more down the road.

Best Times to Find Greenhouse Kits on Sale

Timing truly does play a huge role in finding the best deals on greenhouse kits. Here’s when you should be on the lookout for the biggest savings:

1. Early Spring (Pre-Gardening Season):
   As soon as the weather starts warming up and gardeners everywhere get excited to start planting, stores often begin rolling out new greenhouse kits for the season. During this time, you might find introductory sales to attract early buyers.
   
   
2. End-of-Season Sales (Late Summer to Early Fall):
   The absolute best time to find great deals is towards the end of the gardening season. As summer starts to wind down and fall approaches, many retailers are looking to clear out their inventory to make space for winter stock. This is when you’ll see significant price drops on greenhouse kits, especially for larger, pricier models.
   
   
3. Major Shopping Events (Black Friday, Cyber Monday, etc.):
   Big shopping holidays like Black Friday, Cyber Monday, and even Memorial Day or Labor Day are prime times to catch greenhouse kits on sale. Retailers—both online and in-store—tend to offer limited-time flash sales, so if you’re quick, you can grab a great kit at a fraction of its regular price.
   
   
4. End of the Year Clearance Sales (December/January):
   Once the holiday shopping rush is over, many stores do a post-holiday clearance event to get rid of leftover stock from the year. This is another excellent time to find discounts on greenhouse kits, especially if you’re eyeing models that didn’t sell out during the earlier sales. Even though it’s winter and gardening may be far from your mind, buying a kit at this time sets you up for success when spring rolls around.

Features to Consider Before Buying a Greenhouse Kit

When you’re shopping for a greenhouse kit, it’s important to look beyond just price. The features of the greenhouse will have a big impact on how well it works for your gardening needs and how long it lasts. Here are the key features to keep in mind:

1. Size

The size of your greenhouse is one of the most important decisions. Think about how much space you have in your yard and what you plan to grow. If you’re just starting out or have a small garden, a compact model might be perfect. But if you want to grow a variety of plants or even trees, you’ll need something larger.

• Impact on Price: Larger greenhouses typically cost more, not just for the kit itself but also for the foundation or base. However, bigger sizes often come with better features, like multiple shelves or zones for different types of plants.
• Durability: Bigger greenhouses are often sturdier because they need to handle more weight and weather exposure. But make sure you’re choosing a quality kit that can stand up to the elements.

2. Material

Greenhouses come in different materials, and each type has its own pros and cons:

• Polycarbonate Panels: These are popular because they’re lightweight, durable, and offer good insulation for plants. They also filter sunlight well, which prevents plants from getting scorched. Polycarbonate greenhouses are often more expensive than other materials, but they tend to last longer and provide better protection.
• Glass: Glass looks great and allows maximum light into the greenhouse. It’s also more resistant to scratching than plastic. However, it’s more fragile and expensive, and you’ll need a stronger frame to support it. Glass greenhouses are best for gardeners who want something long-lasting and don’t mind paying extra for aesthetics.
• Plastic or PVC: These materials are lightweight and cheap, making them good options for beginners or those on a tight budget. However, plastic greenhouses may not last as long or provide as much insulation as other options.
• Impact on Price: Polycarbonate and glass greenhouses cost more upfront, but they tend to last longer and provide better protection, which might save you money in the long run. Plastic and PVC models are cheaper but may need to be replaced more often.

3. Ventilation

Good airflow is essential for a healthy greenhouse. Plants need fresh air to grow properly, and the ability to control temperature and humidity is key. Look for greenhouses with built-in vents, windows, or doors that can be opened to let air circulate.

• Manual vs. Automatic Vents: Some kits come with automatic vents that open when it gets too hot, which is great for gardeners who don’t want to constantly check on their plants. Manual vents are cheaper but require more hands-on work.
• Impact on Price: Greenhouses with better ventilation systems (especially automatic ones) tend to be more expensive, but they can save you a lot of hassle, especially during hot or humid seasons.
• Durability: Proper ventilation helps prevent mold, mildew, and overheating, which can damage both the greenhouse and your plants. Investing in a greenhouse with good ventilation can extend the life of the structure and keep your plants healthier.

4. Ease of Assembly

How easy (or difficult) it is to put the greenhouse together should be a big consideration. Some kits are designed to be set up with minimal tools and experience, while others may require professional help or take days to assemble.

• Pre-Fabricated Kits: Many greenhouse kits are designed to be relatively easy to assemble and come with clear instructions. These are great if you want to set up your greenhouse quickly and start planting right away.
• Custom or Larger Kits: If you’re going for a larger or more specialized greenhouse, it may take longer to put together, and you might need help. It’s a good idea to look at customer reviews to see how easy the assembly process really is.
• Impact on Price: Simpler, easy-to-assemble kits tend to be more affordable, while larger, more complex setups may require extra costs for installation.
• Durability: A well-assembled greenhouse is more stable and will last longer, especially if it’s secured correctly to a foundation. If a kit is hard to put together and isn’t properly installed, it could be more vulnerable to weather damage.

Conclusion

Finding the perfect greenhouse kit on sale doesn’t have to be difficult. Whether you’re checking out deals on Facebook Marketplace, Craigslist, or from big online retailers like Amazon, there are plenty of ways to save money without sacrificing quality. By keeping an eye on seasonal sales, comparing prices, and knowing what features are most important for your gardening needs, you can get a great deal and set up your dream greenhouse.

Remember, investing in the right greenhouse will help you grow your plants year-round and protect them from the elements. So, take your time, shop smart, and enjoy the benefits of gardening with a greenhouse without breaking the bank!

FAQs

Are greenhouse kits worth it?

Yes, greenhouse kits are definitely worth it, especially if you love gardening. They provide a controlled environment for your plants, protect them from harsh weather, and extend your growing season so you can garden year-round. Plus, with so many kits available, you can find one that fits your space, budget, and gardening needs. Whether you’re a beginner or an experienced gardener, a greenhouse kit makes the whole process easier and more efficient.

What is the cheapest way to build a greenhouse?

The cheapest way to build a greenhouse is by using simple, affordable materials like PVC pipes and plastic sheeting. You can create a DIY frame with PVC pipes, which are lightweight and easy to work with, and then cover it with clear plastic to protect your plants. It might not be as durable or fancy as a pre-made kit, but it’s a budget-friendly way to get started with greenhouse gardening. You can also look for second-hand materials on platforms like Craigslist or Facebook Marketplace.

Which is better: a white or green greenhouse?

Both white and green greenhouses have their benefits, but the choice depends on your needs. A white greenhouse typically reflects more light and heat, which helps keep the temperature stable and prevents plants from overheating. This makes it a good option for hot climates or sensitive plants.

On the other hand, a green greenhouse tends to blend into the garden more, but it might not be as effective at controlling light and heat. If you’re looking for a greenhouse that helps regulate temperature better, white might be the better choice.

What is better than a greenhouse?

If you’re looking for something more versatile or easier to manage, a polytunnel or a cold frame might be better than a traditional greenhouse. Polytunnels are larger, flexible structures made from metal frames and plastic sheeting, offering more growing space and often being cheaper than glass greenhouses.

How long do greenhouse kits last?

The lifespan of a greenhouse kit depends on the materials and how well it’s maintained. Kits made from sturdy materials like polycarbonate or glass can last up to 10-20 years if properly cared for. Plastic or PVC kits may not last as long—usually around 3-5 years—because they are more prone to wear and tear from the weather. Regular maintenance, such as cleaning the panels and ensuring the frame is secure, can help extend the life of your greenhouse kit.
