The Grandio Ascent 8x12 Greenhouse Kit is built for gardeners who want dependable year round growing space with strong insulation, durable construction and a comfortable interior layout. Its almost 8 foot peak height gives you generous vertical room for tall crops and shelving, while the 1.6 mm aluminum frame and 6 mm twin wall polycarbonate panels combine to create a greenhouse designed to handle challenging weather when properly installed.
Whether you are expanding a backyard garden or building a more structured planting environment, the Ascent 8x12 delivers a balance of strength, insulation and ease of use that makes it a trusted choice among both new and experienced growers.
Designed for Consistent, All Season Growing
The 6 mm twin wall polycarbonate glazing provides reliable insulation with an approximate R value of 1.54 and U value of 0.65. This helps maintain warmer interior temperatures and reduces heat loss during cooler months, supporting plant growth throughout the year when paired with proper heating and ventilation. The Ascent’s A frame style design not only offers an attractive profile but also creates a more efficient interior layout that supports both horizontal and vertical growing setups.
BENEFITS
Better Durability and Insulation: The Ascent 8x12 Greenhouse Kit is made with 6mm twin-wall polycarbonate panels that provide great insulation with an R-VALUE of 1.54 and a U-VALUE of 0.65. This makes sure that the greenhouse stays at the right temperature for winter growing. It is stronger and lasts longer than other frames because it is made of 1.6 mm aluminum metal frame, which is resistant to wind and snow.
Better Air Flow and Ease of Access: This greenhouse has three roof windows, built-in rain gutters, and a snow load kit. It allows for good air flow and water management, making it a great space for plants to grow. The gliding double doors hang from above, which keeps them from getting stuck, and they have durable nylon wheels that make them easy to use.
Easy Assembly with Comprehensive Features: The Ascent 8x12 Greenhouse Kit is easy to put together because it comes with a base kit and was thoughtfully designed. This greenhouse combines smart engineering with useful features that make setup easy and safe, making any gardener's dream come true, whether you're making your backyard into an oasis or setting up a professional growing space.
No matter the weather or season, the Ascent 8x12 Greenhouse Kit can help you make a green space thrive.

Drain Kit - Downspout for Grandio Greenhouse Gutter Systems, designed for installation at each of the four corners of the greenhouse. It’s made to be installed directly into the aluminum frame and gutter of the greenhouse. The easy-to-install downspout drain kit includes (4) 20mm black pipes, (4) gutter attachment gaskets, and (4) side wall brackets with screws. One kit has everything needed to add downspouts to a Grandio Greenhouse.
Automatic Roof Vent Opener - Automatically opens and closes the roof vent window based on temperature changes. The opener contains a metal cylinder with a mineral that expands when heated, pushing a piston to open the vent. When the temperature cools, the mineral contracts, and a spring closes the vent, resetting the piston. The vent opens and closes gradually, allowing the right amount of airflow for cooling.
Auto Louver Window Opener - Automatically opens and closes the louver window as the temperature changes. The opener has a metal cylinder with a mineral that expands when heated, pushing a piston to open the vent. As the temperature cools, the mineral contracts, and a spring closes the vent and resets the piston. The vent opens and closes gradually, providing just the right amount of airflow for cooling. This Auto Louver Opener attaches to the left side of your louver window.
Louver Window - add more ventilation to your greenhouse. Louver window frame comes powder coated in green, with 6mm twin wall polycarbonate panels.
The Drip Irrigation Watering Kit - is a water-efficient system designed for shrubs, trees, flowers, and bushes, covering up to 150 square feet with easy expandability. It's a DIY-friendly installation with no gluing required, using high-quality UV-resistant materials. The kit includes 24 pressure-compensating drippers (20 at 1 GPH, 2 at 2 GPH, and 2 at 4 GPH) for consistent water delivery to plant roots. A backflow preventer ensures water safety by preventing siphoning into the main supply.
Moisture Control Kit - featuring Anti Dust Tape and Waterproof All-Weather Silicone Caulk, protects your Grandio Greenhouse from insects, dirt, mold, and algae. The tape's 45-micron filters allow condensation to escape while preventing algae and mold growth with a fungicidal coating. Combined with the silicone caulk, this kit ensures long-lasting protection and maintains the greenhouse's pristine condition.
Shade Net - are essential for regulating greenhouse temperatures, especially during sunny spring, autumn, and summer days. Designed to reduce intense sunlight by 50%, they help keep your greenhouse cooler and prevent overheating.
Plant Hangers - These versatile plastic hangers are designed for greenhouse use, supporting shade cloths, hanging baskets with quarter-inch hooks, and stringing taller plants or vines. Easy to install, they simply twist into the roof rafter channels.
Frame to Base Brackets - enhance greenhouse stability by securing the frame to the base, offering extra support against wind and severe weather. Each pack includes 4 EZ1 wall-to-base brackets, 4 EZ2 inner base brackets, and 16 bolt-and-nut combos.

I bought this battery to replace my battery that died in my Ecotric 20810 (the fat tire one from around 2019 timeframe). Went on a 2+ hour ride and still had plenty of juice to spare. Wish it was cheaper but....it's a big battery and that's the retail price I guess.
Ordered four inverters for a customer whose solar system was damaged by a utility surge. OffGridLux advertised these inverters at $2500. Upon ordering the inverters I was assured they were in stock and would be delivered. The next day I received a refund and the price of the inverters went up from $2500 to $3100 on the OffGridLux website. Chris in customer service explained the inverters were a new product and the $2500 price was added by mistake and the real price was $3100. He also told me his warehouse made a mistake they only had 2 of the 4 available. After expressing my frustration at the situation since the customer was already quoted the lower price, Chris worked out a deal and gave us the inverters at cost to OffGridLux for $2850 instead of $3100. Chris promptly adjusted the charge and made sure the 2 inverters were shipped out asap. As a small business owner I understand how small mistakes can be costly and sometimes the little things are the biggest problem. In good fashion Chris represented OffGridLux and my interests by communicating and figuring out an amicable solution for all parties involved. Thank you again Chris. You sir a true asset to your company.
Nice bike love the looks not as powerful as my pro 2 as one might expect but overall nice bike i did take it on a 47 mile trip and still had 50.1 percent left when i got home so no need to worry about a battery the best part of this bike is the company that sold it. I've been so impressed with this company which is why i purchased my 2nd bike from them they are nothing short of exceptional buy with confidence they are with your every step of the way and very fast to respond to emails and help with any problem ive come across i wish they sold other bikes just so i could buy from them off the grid lux is by far my favorite store keep it up guys I'll keep looking to see what you stock next
This place is one of the best companies I've ever purchased from they have excellent customer service fast shipping and answer all your questions in a timely manner i love my bike i had a small problem which they quickly addressed i have been extremely impressed with how helpful they have been i highly recommend this company I promise you won't regret it
First id like to say that their customer service is 2nd to none. I was informed about everything that was going on with my new bike they are very fast to respond to messages and shipping is extremely fast buy with confidence you won't regret it
I purchased the Mirage Vision 55 Gold Ultra HD (4K) Series HDTV two weeks ago and have enjoyed watching football and other sporting events on my patio. The TV's weatherization modifications are very professionally installed. I feel like I received a well engineered product and one that will hold up to the weather elements here in central Texas. The picture quality is outstanding. The video/audio source for my Mirage Vision HDTV is a HDMI cable that runs to a cable box in a closet in the house. I'm using a HDMI IR extender to control the cable box in the house and it all works great. The WIFI capability of the HDTV works well too as my daughter enjoys watching Netflix. Nice product!"
The bike is excellent! My range anxiety is no more! 18 miles and only lost 8 percent compared to my last e-bike that is a huge win! I bought this to use as a commuter and man it's been more then enough! Crossing the road and reaching the max speed of 44mph despite being a little under 250! This is my best purchase for the year cant wait for more relaxing extended bike trips!
Shipping was fast, setup was easy and they even followed up after delivery which I totally didn’t expect! Pretty solid experience overall ,would buy again.
I was a little hesitant before buying, but after riding it for a few weeks, I can confidently say it was the right choice. The bike is fast, smooth, and super fun to ride. It handles hills effortlessly, and the battery lasts way longer than I expected.
Shipping was quick, and it was easy to set up. Customer service was also great they answered my questions fast and made sure everything was good.
The equipment arrived packaged very well and in great shape. Quick shipping and tracking information. The freeze dryer and industrial pump has worked wonderfully. Many batches of candy. Batches of chicken, spaghetti sauce, minestrone soup and tons on apple slices, wedges and apple sauce. Enjoying the machine while preparing for the future.
I was super scared to buy it at first because it took a little over a year to save for it, I received it in just about a months time and it’s been running almost non stop since it arrived! I had to get extra trays to prefreeze my next load because im always thinking of something else to go in lol. No issues so far, super happy with it :) Thanks Stayfresh!
Awesome bike. Was delivered on time. Bike was in good condition, no dings or dents. This website had the best price available.
