Not all greenhouses are made the same and the MONT line by Riverstone Industries proves this to be true. The MONT is constructed from the highest quality extruded aluminum and professional grade 8mm polycarbonate panels, making it comparable to commercial grade greenhouses. It is also backed by the strongest warranty in the industry (10 years). 

The twin wall polycarbonate acts as a double pain window, keeping cool air in during the warmer months and insulating the greenhouse from cold air in the winter months. This makes the MONT an ideal greenhouse for gardeners who want to grow year round. 

The above average height (7ft 6") gives you plenty of space to grow taller plants and also helps with displacing heat. As your needs change, you can add 4ft extensions to your greenhouse to provide additional space at any time after your purchase.

The MONT is a practical option with the durability of a commercial grade greenhouse, you definitely get what you pay for!

Features:

✔️ Premium comes with accessories! (shade cloth, work bench, programmable water system, and greenhouse sink system)

    What is Affirm?

    Affirm is a financing alternative to credit cards and other credit-payment products. Affirm offers instant financing for online purchases to be paid in fixed monthly installments over 3, 6, or 12 months.

    Why buy with Affirm?

    • Buy and receive your purchase right away, and pay for it over several months. This payment option allows you to split the price of your purchase into fixed payment amounts that fit your monthly budget.
    • If Affirm approves your loan, you'll see your loan terms before you make your purchase. See exactly how much you owe each month, the number of payments you must make, and the total amount of interest you'll pay over the course of the loan. There are no hidden fees.
    • The application process is secure and real-time. Affirm asks you for a few pieces of information. After you provide this information, Affirm notifies you of the loan amount that you're approved for, the interest rate, and the number of months that you have to pay off your loan -- all within seconds.
    • You don't need a credit card to make a purchase. Affirm lends to the merchant directly on your behalf.
    • You may be eligible for Affirm financing even if you don't have an extensive credit history. Affirm bases its loan decision not only on your credit score, but also on several other data points about you. 
    • Affirm reminds you by email and SMS before your upcoming payment is due. Enable Autopay to schedule automatic monthly payments on your loan.

    What is required to have an Affirm account?

    To sign up for Affirm, you must:

    • Be 18 years or older (19 years or older in Alabama or if you're a ward of the state in Nebraska).
    • Not be a resident of Iowa (IA) or West Virginia (WV).
    • Provide a valid U.S. or APO/FPO/DPO home address.
    • Provide a valid U.S. mobile or VoIP number and agree to receive SMS text messages. The phone account must be registered in your name.
    • Provide your full name, email address, date of birth, and the last 4 digits of your social security number to help us verify your identity.

    How does Affirm work?

    1. At checkout, choose Pay with Affirm.
    2. Affirm prompts you to enter a few pieces of information: Name, email, mobile phone number, date of birth, and the last four digits of your social security number. This information must be consistent and your own. 
    3. To ensure that you're the person making the purchase, Affirm sends a text message to your cell phone with a unique authorization code.
    4. Enter the authorization code into the application form. Within a few seconds, Affirm notifies you of the loan amount you're approved for, the interest rate, and the number of months you have to pay off your loan. You have the option to pay off your loan over three, six, or twelve months. Affirm states the amount of your fixed, monthly payments and the total amount of interest you'll pay over the course of the loan.
    5. To accept Affirm's financing offer, click Confirm Loan and you're done.   

    After your purchase, you'll receive monthly email and SMS reminders about your upcoming payments. You can also set up autopay to avoid missing a payment.  Your first monthly payment is due 30 days from the date that we (the merchant) processes your order.

    How does Affirm approve borrowers for loans?

    • Affirm asks for a few pieces of personal information: Name, email address, mobile phone number, date of birth, and the last four digits of your social security number. 
    • Affirm verifies your identity with this information and makes an instant loan decision. 
    • Affirm bases its loan decision not only on your credit score, but also on several other data points.  This means that you may be able to obtain financing from Affirm even if don't have an extensive credit history.

    Does Affirm perform a credit check? Does it impact my credit score?

    Although Affirm performs a credit check when you apply for a loan, this won't impact your credit score. However, if you're approved and decide to buy with Affirm, your loan and payments may affect your credit score.  Paying on time can help you build a positive credit history. 

    Why was I denied financing by Affirm?

    The merchant has no information regarding a customer's financing denial. Affirm strives to offer all credit-worthy applicants financing with Affirm, but isn't able to offer credit in every case. Affirm will send you an email with more details about its decision. Unfortunately Affirm's decision is final.

    Why was I asked to verify my identity?

    If Affirm has difficulty confirming your identity, you may need to provide more information. Affirm uses modern technology to confirm your identity, including verifying your address or full SSN, or requesting a photo of your ID. Affirm takes these steps in some cases to counter fraud and provide the most accurate credit decision they can.

    Why was I prompted to enter my income?

    Affirm may sometimes need more information about your finances and your ability to repay in order to make a credit decision. Your income gives Affirm additional insight into your ability to repay.

    Why was I prompted for my checking account?

    Affirm may sometimes need more information about your finances and your ability to repay in order to make a credit decision. If you are prompted to link your checking account and would like to proceed, please provide the login information for your online bank account. Affirm does not store your online login credentials---they are transmitted securely to your bank.

    If Affirm asks you to link your checking account, Affirm won't be able to offer you credit if:

    • Your bank is not listed
    • You choose not to link your checking account
      You don't use online banking
      The username and / or password you provide is incorrect
      *You're unable to successfully connect your checking account

    Why is my bank not listed?

    Although Affirm is continually adding support for additional banks, they aren't able to connect to every bank at the present time. We apologize for the inconvenience. If you're unable to connect your bank, you'll need to complete your purchase with another payment method.

    Why was I prompted for a down payment?

    Affirm isn't always able to offer credit for the full amount you request. In these cases, Affirm asks you to make a down payment with a debit card for the remainder of your purchase. The down payment amount can't be changed and must be made upon confirming your loan and before the loan offer expires.

    Will I see how much interest I am paying prior to accepting my loan?

    Yes! Affirm works hard to be completely transparent. You'll see the amount of interest you'll owe on the terms page and again on the loan confirmation page. If you pay off your loan early, you'll receive a rebate for any interest that hasn't yet accrued.

    Why can't customers outside the U.S. use Affirm?

    Affirm is available only to shoppers residing in the United States. Affirm hopes to expand its services to customers outside the U.S. in the future.

    What are Affirm's fees?

    The annual percentage rate (APR) on an Affirm loan ranges from 10% to 30%. Affirm discloses any required fees upfront before you make a purchase, so you know exactly what you will pay for your financing. Affirm does not charge any hidden fees, including annual fees.  

    Why is my Affirm interest rate so high?

    When Affirm determines your annual percentage rate (APR), it evaluates a number of factors, including your credit score and other data about you. If you finance future purchases with Affirm, you may be eligible for a lower APR depending on your financial situation at the time of purchase.

    This APR calculator will give you an idea of how much interest you actually pay: https://www.affirm.com/apr-calculator/

    When you consider Affirm financing, carefully evaluate the loan terms that Affirm offers you and determine whether the monthly payments fit your budget.  

    How is interest on an Affirm loan calculated?

    Affirm calculates the annual percentage rate (APR) of a loan using simple interest, which equals the rate multiplied by the loan amount and by the number of months the loan is outstanding. 

    This model differs from compound interest, in which the interest expense is calculated on the loan amount and the accumulated interest on the loan from previous periods. Think about compound interest as "interest on interest," which can increase the loan amount. Credit cards, for example, use compound interest to calculate the interest expense on outstanding credit card debt.

    8x16 greenhouse

    Unlike some reviews or videos I watched, I thought this greenhouse was well engineered. What I thought was lacking was good directions. There was next to no narrative. Each step has its own learning curve. As a consumer, we will probably only erect one greenhouse, so detail written instructions would have cut several hours off out installation time. But all in all, this is a very good greenhouse and my wife is very happy.

    Hi William! Thank you so much for your thoughtful and detailed review! This is incredibly helpful to us. I wanted to let you know we've taken the good and the bad elements you've mentioned in your review to heart. Thank you again for taking the time to share your experience with us. :)

    Yes I built a Mont 8 x 20 growers greenhouse part 2

    Step 10: I now removed the 6 screws holding the metal base to the 2x4’s and checked the alignment and level of all the walls. Once I was satisfied with my results, I then went around and install all the required screw for the base. Then I went inside and started installing all the structural brackets, making sure all fits and finished were properly aligned and closed (vertical structures meet horizontally structures) and tighten all down securely.

    Step 11: install the vents. This was straight forward and went together without any problems.

    Step 12: I then mounted the doors, which was easy because I made sure the structure as a whole was level and true.

    Step 13: drilling the anchor screws into the ground. I started by installing all 10 of the anchor screw bracket, then I drove the anchor screws into the ground with my 1/2” dewalt cordless impact driver. Made short work of what is a daunting task.

    Step 14: install the bench. This was straight forward without any problems.

    Assemble was finished!!!!

    End of day 2

    To finish off my greenhouse I decided to get 10 yards of what was described to me a “large pea gravel” by the excavator. He said that small pea gravel would feel like sand under my feet all the time and that the larger (3/4”) pea gravel would give extra support. I agree now that is is inside the greenhouse.

    I still have to install the electric and I places a 2” PVC pipe, trenched into the ground while I was building the base to accommodate this. I am bringing a 50 amp two phase sub-panel with 6 breakers for lights, outlets, heater and vent fan.

    I am also bringing a water supply line to the greenhouse, but that will have to wait until spring.

    Conclusion…

    Except for a few hiccups from manufacturer’s errors, this greenhouse went up relatively easy and to be honest, it is of really good quality. I can’t fault the manufacturer for an employee’s mistake when they describe the spacer bar correctly in the manual, so I still gave it a 5 out of 5 because the greenhouse itself was manufactured correctly and went up as described in their manual. I have included lot of pictures to help anyone else in the future.

    Yes I built a Mont 8 x 20 growers greenhouse - part 1

    Our location is approx 40 miles south of Lake Superior in northern Wisconsin.

    I’m am going to start with complaints and get them out of the way.

    First complaint happened when assembling the first wall “right side”. We set the corner, placed the spacer between each vertical support and when we got to the next corner 20’ away, we were short by 1-1/4”. After review of our work, (checking each distance between the vertical supports, we came to and verified that the spacer rod was cut to exactly 23” instead of 23-1/8” as described in the manual. This required us to move all 9 of the vertical supports to accommodate the missing 1/8”. Now that we know this, everything went together much smoother.

    Second complaint… couldn’t the manufacturer supply a couple of rolls of aluminum tape (buy 1” wide) to cover the tops and bottoms of every panel?
    (We taped the top and bottom of every panel when we placed them during assembly)

    Third complaint… couldn’t the manufacturer supply caulking for the gutters???

    Fourth complaint… could the manufacturer please file all drilled holes? For what this greenhouse kit cost, they could at least clean the holes of drilling burrs. I know this may sound like a minor complaint, until you have to put one of those “T” bolt into a location where burrs are present.

    With that said, and after working through these complaints, this kit went together surprisingly easy!!!

    Tips…
    If you can, have a cordless drill with a Phillips bit, a small cordless dewalt impact drill (inch lbs not foot lbs), with an extension and a 7/16 socket for the cap nuts, and large impact drill (foot lbs) with a 1” socket to drill the 10 screw-in anchors into the ground. Also have the screw drive and open/box wrench supplied, handy too.

    Building the greenhouse:

    My son and I are both engineers and after the site preparation, it took us two full eight hour days (even with the spacer bar problem), to complete the build.

    Step 1: I hired an excavator to deliver and level a 15’ x 25’ pad of compressible crushed rock for my starting base. This cost $900 and was worth every penny because it gave us a level platform from which to start and it made the build go smoothly.

    Day 1

    Step 2: I skipped the pre-builds and start first on the 2x4 base and made sure it was square from corner to corner. Put all the recommended screws to securely fasten it together. I then assemble the base on top of wood base, securing it with 6 screw, four corners and 1 in the middle of each long run. This will allow for movement while doing assembly.

    Step 3: now I did the pre-builds and set them aside.

    Step 4: assembled to right side wall and found myself short, but after the adjustment, all went well. When placing the pre-assembled gutter on the right side, here is a tip; align the centers of every other vertical support with the centers of the splices of the gutters, then go back with the spacer bar and align the vertical supports between the aligned supports. Much easier and more accurate.

    Step 5: assemble the back wall. This went together relatively easy. Make sure you cut the poly as describe in the assembly instructions with a razor knife.

    End of first day…probably could have finished the left wall if we didn’t encounter the spacer problem…

    Day 2

    Step 6: assemble the left side wall. This time (knowing about the missing 1/8”), the wall went up without a hassle. Again align every other vertical support with the gutter splices.

    Step 7: assemble the front wall. This went up without a hassle except I needed to file all the drill hole to remove burrs…

    Step 8: placing roof ridge. Make sure you have the required 2x4’s to support the roof ridge until you can secure it by assembling the roof.

    Step 9: assembling the roof. Take 4 of the 45 degree angle brackets and drill out the center holes just slightly larger then they are, you will thank me when you use them on the roof assembly where the large roof ridge bolt passes through them.
    If you follow what I am writing here for the roof assembly, it will make the job much easier by the end of this assembly. so that said…

    Start by placing the two poly panels into the roof ridge and the back wall channel’s, then place the vertical supports on the open ends and loosely secure the supports with the (3) 45 degree angle bracket (top and 2 sides). Place the next two panels in place, then align the next two vertical supports to the gutter and roof ridge splices, centering on each. Lock these down by tightening the angle bracket. Now go back and use your spacer to align the previous vertical supports and lock them down too.
    Continue this pattern until the roof is complete. Following the splices in the roof ridge and gutter assemblies will insure proper roof spacing.

    Excellent design and materials, except doors.

    Premium kit design requires some construction expertise to execute. Ingeniously designed except for doors which seem to be an afterthought. Doors should be set into frame with flange for proper attachment and sheltering of weather strip. Lock system should be more central and reachable on door. Should consider the option of right or left opening access of double door. Open springs for door closer are dangerous and inconvenient. Plexiglass panels and vent system work to provide an ideal environment for greenhouse plants. System is physically strong and plumb. The shelf system is versatile and well designed.
    Our winter winds here in the Bitterroot Valley of Montana will be the true stability test. We will be building a fence to help mitigate the force of those winds from the north. For the price, it should have a better door system. The construction instructions should be reviewed by neophyte consumers. Near the end of the manual, drawings and instructions are less clear, ie. door, hinges, lock, and insulation strips

    My son and I are both engineers and after the site preparation, it took us two full eight hour days (even with the spacer bar problem), to complete the build.

    Step 1: I hired an excavator to deliver and level a 15’ x 25’ pad of compressible crushed rock for my starting base. This cost $900 and was worth every penny because it gave us a level platform from which to start and it made the build go smoothly.

    Day 1

    Step 2: I skipped the pre-builds and start first on the 2x4 base and made sure it was square from corner to corner. Put all the recommended screws to securely fasten it together. I then assemble the base on top of wood base, securing it with 6 screw, four corners and 1 in the middle of each long run. This will allow for movement while doing assembly.

    Step 3: now I did the pre-builds and set them aside.

    Step 4: assembled to right side wall and found myself short, but after the adjustment, all went well. When placing the pre-assembled gutter on the right side, here is a tip; align the centers of every other vertical support with the centers of the splices of the gutters, then go back with the spacer bar and align the vertical supports between the aligned supports. Much easier and more accurate.

    Step 5: assemble the back wall. This went together relatively easy. Make sure you cut the poly as describe in the assembly instructions with a razor knife.

    End of first day…probably could have finished the left wall if we didn’t encounter the spacer problem…

    Day 2

    Step 6: assemble the left side wall. This time (knowing about the missing 1/8”), the wall went up without a hassle. Again align every other vertical support with the gutter splices.

    Step 7: assemble the front wall. This went up without a hassle except I needed to file all the drill hole to remove burrs…

    Step 8: placing roof ridge. Make sure you have the required 2x4’s to support the roof ridge until you can secure it by assembling the roof.

    Step 9: assembling the roof. Take 4 of the 45 degree angle brackets and drill out the center holes just slightly larger then they are, you will thank me when you use them on the roof assembly where the large roof ridge bolt passes through them.
    If you follow what I am writing here for the roof assembly, it will make the job much easier by the end of this assembly. so that said…

    Start by placing the two poly panels into the roof ridge and the back wall channel’s, then place the vertical supports on the open ends and loosely secure the supports with the (3) 45 degree angle bracket (top and 2 sides). Place the next two panels in place, then align the next two vertical supports to the gutter and roof ridge splices, centering on each. Lock these down by tightening the angle bracket. Now go back and use your spacer to align the previous vertical supports and lock them down too.
    Continue this pattern until the roof is complete. Following the splices in the roof ridge and gutter assemblies will insure proper roof spacing.

    Excellent design and materials, except doors.

    Premium kit design requires some construction expertise to execute. Ingeniously designed except for doors which seem to be an afterthought. Doors should be set into frame with flange for proper attachment and sheltering of weather strip. Lock system should be more central and reachable on door. Should consider the option of right or left opening access of double door. Open springs for door closer are dangerous and inconvenient. Plexiglass panels and vent system work to provide an ideal environment for greenhouse plants. System is physically strong and plumb. The shelf system is versatile and well designed.
    Our winter winds here in the Bitterroot Valley of Montana will be the true stability test. We will be building a fence to help mitigate the force of those winds from the north. For the price, it should have a better door system. The construction instructions should be reviewed by neophyte consumers. Near the end of the manual, drawings and instructions are less clear, ie. door, hinges, lock, and insulation strips
