This video provides a comprehensive guide on how to improve your Harbor Freight greenhouse. It covers a 2-year review of the 10×12 greenhouse, including modifications made and ongoing improvements. The greenhouse was initially built as a small 6×8 greenhouse, but was later upgraded with height, raised bed grow boxes, and a custom Cedar door with a wooden latch. The greenhouse was also fitted with a weather station.
The video also discusses the process of replacing worn-out panels in a greenhouse. The in-house repair technician, Mark, will guide the user through the process. Reviewers suggest that the clips holding the panels in work effectively and that purchasing additional clips is a good option.
The video also discusses the importance of building the base, supporting structure (benches and shelving), and using aluminum. The video also discusses the importance of silicone and clear duct tape for a hurricane-resistant greenhouse.
The video concludes by recommending that those considering a Harbor Freight greenhouse should consider the following factors before purchasing: building the greenhouse, strengthening it, and using it. The Harbor Freight Greenhouse Modification is a great resource for those who haven’t built their greenhouse yet. The video concludes by offering a step-by-step guide on how to use these items and other essential components for a successful greenhouse.

What increases greenhouse?
The burning of fossil fuels, deforestation, and livestock farming are causing a significant increase in greenhouse gases, leading to global warming. The 2011-2020 decade was the warmest, with the global average temperature reaching 1. 1°C above pre-industrial levels in 2019. Human-induced global warming is currently increasing at a rate of 0. 2°C per decade, with a 2°C increase compared to pre-industrial times posing serious environmental and human health risks, including the risk of catastrophic changes.
How to make a greenhouse more effective?
The article provides seven tips to make your backyard greenhouse more efficient. These include optimizing ventilation, eliminating air leaks, adding a shade cloth, minimizing wind exposure, installing a thermostat or full automation, adding insulation to retain heat, and installing interior organization elements to maximize growing space.
To maximize the efficiency of your greenhouse, it is essential to integrate the ability to vent excess heat into its structure. Allowing too much heat to remain inside can damage even warmth-loving tropical plants. Additionally, consider installing a thermostat or full automation to regulate temperature and ensure proper ventilation. Insulation can also help retain heat and maximize growing space.
In summary, optimizing ventilation, minimizing air leaks, adding a shade cloth, minimizing wind exposure, installing a thermostat or full automation, incorporating insulation, and installing interior organization elements are all essential steps to maximize the efficiency of your backyard greenhouse.
What increases CO2 concentration?
Carbon dioxide concentrations are increasing due to the burning of fossil fuels for energy, which contain carbon that plants removed through photosynthesis over millions of years. Since the mid-20th century, annual emissions from burning fossil fuels have increased every decade, from 11 billion tons in the 1960s to an estimated 36. 6 billion tons in 2023. Natural “sinks” on land and in the ocean absorbed about half of the carbon dioxide emitted each year in the 2011-2020 decade.
However, we put more carbon dioxide into the atmosphere than natural sinks can remove, causing the total amount to increase every year. The more we overshoot what natural processes can remove in a given year, the faster the atmospheric concentration of carbon dioxide rises. The annual growth rate of atmospheric carbon dioxide over the past 60 years is about 100 times faster than previous natural increases, such as those at the end of the last ice age 11, 000-17, 000 years ago.
How do you optimize space in a greenhouse?
To maximize greenhouse space, plant different crops at different times of the year, taking advantage of seasonal conditions like longer days or higher temperatures. Plant cold-tolerant crops in fall and winter to reduce energy required to heat the greenhouse, while heat-loving crops in summer enable high yields. Utilize succession planting by planting multiple crops in the same space, with each crop planted at different times.
Various ways to take advantage of headroom in your greenhouse include hanging baskets, tiered shelves, vertical planters, and hydroponics. Hanging baskets can be hung from the ceiling or shelves, freeing up floor space and adding visual interest. This space is perfect for preparing flowers or ferns for centerpieces or porch plants.
What strengthens the greenhouse effect?
The burning of fossil fuels is accumulating CO2 as an insulating blanket around Earth, trapping more of the Sun’s heat in our atmosphere. This anthropogenic action contributes to the enhanced greenhouse effect, which is crucial for maintaining Earth’s temperature for life. Without the natural greenhouse effect, Earth’s heat would pass outwards, resulting in an average temperature of about -20°C. Most infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted by greenhouse gas molecules and clouds, warming the Earth’s surface and lower atmosphere. Greenhouse gases also increase the rate at which the atmosphere can absorb short-wave radiation from the Sun, but this has a weaker effect on global temperatures.

How do you increase yield in a greenhouse?
This blog entry discusses four tips for improving greenhouse production and reducing costs. Light is crucial for plant growth, and greenhouses can be controlled by adding or upgrading lighting. Temperature, insulation, and humidity are also important factors to consider. Greenhouse cultivation is a popular type of controlled environment agriculture, covering various crops like vegetable and flower greenhouses. Regardless of the type of greenhouse or glasshouse, there are ways to improve production, increase efficiency, and reduce costs.
In addition to adding or upgrading lighting, growers should also control temperature, insulation, and humidity in their greenhouses. By implementing these tips, growers can improve yields and reduce production costs, making greenhouse cultivation a popular and efficient method for controlled environment agriculture.
How do you increase CO2 concentration in a greenhouse?
CO2 can be added to greenhouses through burning natural gas or liquid CO2, which is a common method to increase the yield of greenhouse horticultural crops. The outdoor air contains 350 parts per million of carbon dioxide. The supply can be through pure liquid CO2, fossil fuel combustion with air heaters, or a central burner combined with a heat storage tank. However, local variations in CO2 concentration may occur due to the decline from source to sink.
The main goal is to maintain plant growth and crop production homogeneity. The greenhouse CO2 distribution system, which is placed underneath the growing gutter, ensures that plants benefit from the natural diffusion of CO2 to the top of the greenhouse.
How can yield be improved?
To enhance the yield, it is recommended to utilize a flame- or oven-dried flask and stirbar, clean glassware, precise calculation and weighing of reagent quantities, purification of reagents and solvents when necessary, guaranteeing the purity of reactants, and rinsing of flasks and syringes.
How do we solve the problem of greenhouse effect?
Carbon dioxide is a greenhouse gas that contributes to climate change. It is released into the atmosphere when plants and animals absorb sunlight, reducing the amount of carbon dioxide that is released. Carbon sinks are areas where carbon dioxide is removed from the air, such as forests, grasslands, peatlands, and wetlands. Planting trees, bamboo, and other plants increases the number of carbon sinks. Conserving these areas protects existing carbon sinks.
Farming methods like cover crops and crop rotation maintain soil health, making them effective carbon sinks. Carbon dioxide removal technologies can also help remove large amounts of greenhouse gases from the atmosphere.
How to increase CO2 levels?
Research suggests that sodium bicarbonate or sodium citrate pills can improve metabolic acidosis. Consuming more fruits and vegetables and reducing meat, eggs, cheese, and cereal grains can also help. Consult your healthcare provider for safe CO2 levels. If you experience fatigue, difficulty breathing, weakness, or vomiting and diarrhea, a CO2 blood test may be ordered to assess electrolyte balance. Consult your healthcare provider with any questions or concerns.
📹 Harbor Freight 6×8 Greenhouse | Extended Review + Modifications
In this video I discuss the Harbor Freight 6×8 greenhouse we put up a few years ago and two of the enhancements we made to the …
The reason the clips are used to hold the double wall plastic panels on the aluminum frame pieces is because the frame and the plastic expand at much different rates with temperature changes and the clips absorb the difference in movement. I would bet the panel holes around the “pole barn screws” you used will crack and may split the panel as the materials try to move past each other (this is the same reason vinyl siding has nail slots and the nails are not driven tight). The screws attaching the aluminum frame to the wood base pieces will probably work free as the aluminum tries to move under thermal expansion and contraction too. As to the roof vents, loop a cable tie through the holes in the end of the vent latch strip and make a “L” out of a piece of PVC water pipe, broomstick or other suitable material, where the short end fits into the cable tie loop loosely. You can reach up with the “L”, insert it in the loop and manipulate the window adjustment without ladder or stool, no matter how vertically challenged you may be. 😊
The clips are backwards, the center should be on the panel and the ends into the metal.. Should also caulk the sides of the panels as well helps seal the greenhouse. I have both the 10×12 and the 6×8.. using the small one for a walk in cold frame now and for hardening seedlings. The doors will be tougher to open if it is not properly level… took me a while to get that right.
I had a HF greenhouse for 7 years. It was a 10X12 and we anchored it on 6×6 treated lumber. I would recommend getting some Breathable Polycarbonate tape to cover the bottom part of each panel. I didn’t know that til I decided I was sick of the earwigs and teeny spiders that crawled up the insides of the carbonate panels. So I checked out some blogs and thats what was recommended to me.. On the top of the panels I cut aluminum duct tape to put across the top of the panels to keep the water out. I cut two inch aluminum tape in two lengthwise and folded a 1/2 inch on each side. Charleys greenhouse(.com) in Mt. Vernon Washington is were I get my stuff and I understand that he now has a supply house just for supplies like this. I did get the Poly carbonate breathable tape there. (for the bottoms of the panels. It allows any condensation to drain). But Greenhouse Megastore (.com) has lots of this same stuff. Last year, we had a tremendous amount of snow and mine just caved in. Boy I was just sick. But I just got another one on sale at HF for less than 500 dollars on their march sale with coupons. This time I will put more clips on the panels, six to each side of each panel. I will shore up each corner edge with 2X4’s and put some metal work in the frame from the top of the panels from side to side. . On the other one, I chased a few panels up the street in higher winds but the extra clips solved that problem.The clips on the one in this article are on backwards. The ends of the clips go to the aluminum uprights and the bent out part stays on the polycarbonate.
Oh no. I’m sorry you lost your green house. That happened to the green house at a small rural school in our area, several years ago. I hope you will try again. I made a hoop green house from cattle panels, so we could eat Tomatoes year round. The first few months were great, then real winter arrived in February. An ice storm collapsed my beautiful space, which had become a tomato jungle. Being inside it with the tomato vine smells, the humidity, the warmth compared to outside was awesome. I hope you will try again.
I would make sure that the tank is on a perfectly flat surface. I could see gaps under the tank. Water weighs ~8 lbs. per gal. x what appears to be a 100-120 gal. tank = ~800-960 lbs. of glass shattering force! Thanks for the article, I didn’t realize that you could use a 20% off coupon on the greenhouse, but thanks to your article I’ve tried it and it works!
Bear U is right about the expansion contraction. I got around that by just putting one screw in each panel to perlin all the way around. The ceiling windows are a pain. I kinda fixed that by drilling another hole in the handle thing so I could open the windows more. I also attached an extension but I just kept hitting my head with it so I got a 3 foot electrical conduit and by putting a screw through one end of that I could reach up with that and raise the windows. Anything less than 3′ just won’t work cause of the angle of those things when putting them on the little know sticking out being offset. Oh, one more thing that you probably already know but maybe somebody reading this in the future can avoid the mistake. The air in the panels will expand and contract. When it contracts it will literally suck the caulk up into the tubes and break the seal. The result is you can’t avoid moisture getting it. I tried putting metal foil tape used for heat duct work on the top of each panel and left the bottom open. Waste of time. I sill got mold in the panels. after 3 years I preasure washed them and that helped a little.
You have the panel clips in upside down. I did the same thing. After taking a longer look at the instructions I saw the error of my ways. Had all but 5 panels in and had to change all of the clip installed. Furthermore, if you have wind in your area, these will fail. With the clips in correctly you can make a modification to aid holding in the panels in a wind. I cut lengths of 5/16″ screen molding and placed them against the panels with the square part of the clip holding the lengths of molding in place. I used mill finish aluminum molding so it would match the rest of the structural pieces. The molding is easy to cut with a pwr miter box or you can use a hand miter box and a hack saw. I don’t know yet if my modification will work. But I guess I’ll see.
We bought one of these in 2013. The wind ripped the panels right out of the frames so I used little screws, washers and nuts to hold them in. The panels rotted after I did all that. The frame is somewhat okay but the panels are junk. Only one of the extra cost automatic vent openers worked. The doors aren’t worth having either. HF should provide better door hardware and panel material. I finally gave up on it and bought a real greenhouse. Other stuff I’ve bought at HF has been good. Their greenhouse is not.
Thank you, this was informative! I have been considering this greenhouse to replace my smaller greenhouse, but the reviews are not good on it. However, like yourselves I have rad about other people completing similar modifications and are having some success in keeping the thing together. My opinion is if it works and is maintainable for at least 6 years than you get your money worth and if it needs to be replaced at that point this would be okay.
Oh, one other thing; double walled plastic greenhouse panel is sealed across the top and sometimes the sides of the websites however the bottom is covered with a vented adhesive strip that allows moisture to drip out of the panel when it condenses. If you seal both sides of the bottom of the panel to the frame, the water is trapped inside the panel, clouds it and if it gets cold enough to freeze, splits the panel or the website divider. Older systems used foil or sealant tape along the top and sides of the panels and a mesh tape across the bottom to allow drainage, however some of the newer systems use an aluminum extrusion frame that fits so snugly that weep holes must be added to the bottom of the panel or extrusion instead of the tapes. PS: one side of the plastic is UV resistant and the other is not. The UV resistant side must face out to get proper lifespan of the panels. Hope this helps.

I bought one just like it and so did my neighbor. Both of them blew down with the first little win. Mine was so twisted up and bent I couldn’t salvage it. My neighbor could salvage his. And he had to reinforce it with heavier aluminum and 2×4 lumber. They are made of the lightest aluminum you can find. The sliding doors never did work right. Save your money and build one out of lumber!!!!!!!!!!!!!!!
Those panels don’t last long at all, I bought a smaller harbor freight green house 3 years ago and they didn’t even last that long. The frame is good but the panels are garbage. They look and work great for about one season and then you’re stuck trying to find replacement panels, and guess what? Harbor Freight doesn’t sell just panels, you have to buy a whole new green house. I have replaced them with some better panels I bought from Home Depot, I had to cut them to the right size but it was a chore. Just beware, it only looks good when you first put it together. And the clips that hold the panels in are crap too, anytime a gust of wind comes along the panels blow out.
I am sorry to say but these things are junk. I have one and did all the standard reinforcements that everyone says. The 1/2 inch conduit braces, pop rivets on all the braces to hold the panels in and used small aviation cable to help hold the structure to the 4×4 base. The greenhouse flexed so much that it caused metal fatigue and broke some braces. I have spent the last two days adding a complete 1/2 conduit skeleton to the unit. I sure hope you have better luck than I am having.
