📹 Ten things you must do if you get a polycarbonate greenhouse. This advise is bourn of experience
I give you this advise now bourn of experience and wish someone had given it to me before I built my Polycarbonate greenhouse.
How do I keep my plastic greenhouse warm at night?
Greenhouses are designed to retain heat by minimizing heat loss through insulation, such as double-glazed windows or multiple layers of plastic film. Heating systems, such as electric or gas heaters, wood-burning stoves, or hot water pipes, are used in regions with severe winters to provide additional heat. Ventilation systems regulate temperature and humidity, allowing excess heat to escape during the day and preventing condensation, which can lead to mold and fungal issues.
Automated systems open and close vents or fans based on temperature and humidity settings. Row covers and thermal blankets can be used to trap heat closer to the ground, protecting delicate crops from frost damage.
How long will polycarbonate greenhouse panels last?
Polycarbonate greenhouse coverings are rigid, rigid panels with a life expectancy of 10-20 years. Corrugated polycarbonate offers light diffusion and non-drip benefits, making it easy to cut and install. Greca corrugated polycarbonate sheets are popular and have been replaced by Sinus corrugated panels. Polycarbonate is also available in multi-wall materials, such as twin wall or triple wall polycarbonate, which reduces heat loss and can reach up to 50 degrees Celsius.
Acrylic is a popular choice for greenhouse, nursery, and agriculture applications due to its long-lasting properties. Evonik, a popular brand from Cyro Corporation, is a popular choice for greenhouse and industrial use. Available in various lengths and widths, special accessories are required to contribute to the long life of acrylic panels. Acrylics come in flat sheets, twin wall, and corrugated options. Although expensive, they offer longer life and improved clarity, making them a cost-effective choice for greenhouse and industrial applications.
Do polycarbonate greenhouses leak?
It is not uncommon for polycarbonate sheeting to exhibit leakage and condensation. Therefore, it is advisable to install a ventilating window on your plot at any time.
What thickness polycarbonate is best for a greenhouse?
Polycarbonate sheets are suitable for various climates, including mild to moderate, hot and sunny, cold and snowy, and cold and snowy regions. Mild to moderate climates use 4mm to 6mm polycarbonate sheets for insulation and impact resistance. Hot and sunny climates, like tropical or desert regions, prefer thicker sheets with thicknesses of 8mm to 10mm for thermal insulation and UV protection. Colder regions with heavy snowfall require thicker sheets with thicknesses of 10mm to 16mm for increased structural integrity and insulation, ensuring the greenhouse can withstand harsh winter conditions.
What is a major disadvantage of polycarbonate sheets?
Polycarbonate has limitations such as limited resistance to high temperatures and chemical sensitivity, making it a costly material. It is not inherently flame retardant and requires additives to meet fire safety standards. It is also not suitable for direct food contact due to potential BPA leaching. However, BPA-free polycarbonate options are available. The Definitive Guide to 3D Printing provides a comprehensive guide to the additive manufacturing process, from prototyping to production.
What are the disadvantages of polycarbonate?
Polycarbonate (PC) is a versatile and durable thermoplastic polymer known for its impact resistance and natural transparency. It is highly transparent, making it ideal for applications requiring optical clarity, such as eyeglass lenses and protective shields. PC’s exceptional impact resistance makes it ideal for safety and durability applications, such as bulletproof glass and automotive headlight lenses. It can withstand high temperatures without melting or deforming, making it suitable for applications requiring exposure to elevated temperatures.
PC is lightweight, making it popular for weight reduction in industries like aerospace and automotive. It also has good UV resistance, making it suitable for greenhouse panels and outdoor equipment protective covers. PC is also an excellent electrical insulator, used in electrical and electronic components to prevent short circuits and electrical hazards. However, PC has limitations, such as limited resistance to high temperatures and not being inherently flame retardant.
It can be sensitive to certain chemicals, solvents, and cleaning agents, making it important to select appropriate materials for cleaning and avoid exposure to incompatible chemicals. Additionally, PC can be more expensive than other plastics and may not be suitable for direct food contact due to concerns about bisphenol A leaching.
What material is better than polycarbonate?
Polycarbonate and acrylic are both strong and transparent materials, with acrylic having 17 times the resistance of glass compared to polycarbonate’s 250-times resistance. Both are slightly cheaper and have various manufacturing uses, including molding and CNC machining. However, acrylic is generally cheaper than polycarbonate due to its higher strength and melting point. Prices for polycarbonate sheets range from $2. 50 to $3. 50 per kilogram, while acrylic sheets range from $1. 50 to $2. 00 per kilogram. Prices may vary depending on location and type of plastic.
Will a polycarbonate greenhouse stay warm in the winter?
Polycarbonate has become a popular material for greenhouses due to its durability, flexibility, and ability to create complex geometric shapes. Its high light transmission and thermal insulation make it a cost-effective choice for heating, reducing winter crop costs. Polycarbonate greenhouses are also used in landscape design and can be purchased ready-made, made to order, or installed by hand. They can operate actively in winter, but require heating and lighting systems. If the building is warmed up, the greenhouse season can start a month earlier than usual. This has led to a significant demand for polycarbonate greenhouses in suburban areas.
Which is better for a greenhouse PVC or polycarbonate?
PVC and polycarbonate are both suitable for greenhouse construction, with PVC being more affordable and durable but lacking insulation, UV protection, and longevity. Polycarbonate, on the other hand, is more expensive but offers superior durability, insulation, UV protection, and aesthetic appeal. When choosing a material, consider factors like budget, climate, and desired appearance. PVC may be the cost-effective option for those who can compromise insulation and longevity, while polycarbonate is likely the better choice for those who value durability and energy efficiency.
What is a cheaper alternative to polycarbonate sheets?
Acrylic and polycarbonate are both inexpensive plastics, with acrylic being more cost-effective due to its higher strength and melting point. Prices for polycarbonate sheets range from $2. 50 to $3. 50 per kilogram, while acrylic sheets cost between $1. 50 and $2. 00 per kilogram. Both are recyclable, but acrylic may not be accepted by all recycling programs. Recycling plastic often ends up in landfills, so manufacturers and businesses must monitor waste disposal.
Both plastics are energy-efficient, producing less resources than glass. However, polycarbonate contains bisphenol A (BPA), which is harmful and has been banned globally. It is crucial to consider these factors when choosing a plastic for home or consumer use, as it can have harmful effects on people’s health. Therefore, it is essential to choose the appropriate plastic for the intended use.
📹 Meet the POLYCRUB // my greenhouse-polytunnel hybrid
FINALLY, I’m able to reveal my new Polycrub to you! We’ve been preparing the site and getting it built over the past few weeks …
For your door stop to hold the door. Install a vertical sliding rod ~1/2″ that can be latched in the up position. Drive a piece of pipe big enough for the sliding rod, into the ground at the desired open position. When the door reaches the desired open position, simply release the sliding rod to insert into the ground pipe. Simple and available at most hardware stores.
from my limited poly tunnel experience, it will heat up very quickly when the sun hits….some vents above the doors might be required to keep moving the excessive heat at the top on hot sunny days…..we would fully open both ends of our greenhouses to keep them cooler…even at 40F, 8000ft elevation…..i realize your climate is cooler in general, so i could obviously be mistaken…..
I live here in Shetland and yep, they’re everywhere. In my village nearly every single household has one. Most go for 6×4 or 10×4. We’re going for 8×4. Very useful sturdy structure. Some are quite low so people don’t get as much height as yours seems to have. We’re building our own, as we’re next to a mussel farm who give away their black pipes, so we’re going to make ours a little taller than the local standard.
I love it! 💕 It’s too bad that they’re only located in the uk. We could really use something like that up here in the high deserts of california. Our winds are horrible we tend to have very cold Winters but our summers would probably eat this thing alive. That would be my only concern is that it’s not UV protected enough for temperatures that can get as high as 120°. I do love it however and think that closer to where we have some shade trees that thing would be amazing.
Really beautiful, i owned several greenhouses and polytunnels but this one is very interesting. You need more shade i think, for my polytunnel using building nets are very cheap and effective. Make sure that no moisture can get in the cells otherwise mold got to grow in there, buy special tape for it and seal it. Here at the russian border the snow is just gone, wish you all the best.
It really is fabulous, I love that it’s a recycle build too. I used copper plumbing pipe for a way to hold my arbor gate open, put a 2 – 3 inches in the ground and a solid piece that holds it in place. A friend bent the top of a solid piece that I used a latch to hold it up hooked to the gate, it just falls into the pipe and works great. That property sure did have your name all over it when you heard it would be for sale, you’ve done a beautiful job bringing it back to life.
I don’t know how the thermometer works exactly, but I see it was sat on a concrete block which could have absorbed a lot of heat. My thinking is that the air temperature might be a bit higher immediately above the block compared to the rest of the polycrub. Though looking at the readings it was showing, a few degrees cooler wouldn’t do any harm to plants! Looks like a very nice solid structure, lots of space to grow heat loving plants 🙂
Hi Tanya. I would only bother with an internal latch for the top door. Once open, you can just reach out and down to slide open the bottom latch. Latch could be cheaply made from a strip of wood screwed to the door; open in the vertical and closed horizontal positions. Lovely poly but far too big for my garden!
Wow Tanya, from the angle of your camera at the end you can really see the incline of your slope there. How is that working out physically. I couldn’t imagine gardening up and down that slope, so hats off to you for that. I’m definitely looking towards waist(ish) high beds in my garden – on flat ground! Love the Polycrub – it looks amazing. x
I have a very similar build. I added a water collecting pipes around and dug down a 2500L water tank with a pump inside and pipes going through the whole lenght. Wifi, pump and diy sprinklers are connected to the solar pannel and a battery, so my lazy self can water my stuff without actually going in there lol
We completed similar a few months ago and everything is as you say. It is a lovely place to sit with a cuppa. Cats will love their new toilet so be warned! Recent 85 mph winds had no effect. We used opal shade polycarb, experience showed some plants suffered in high summer. Courgettes WILL take over! Am planning another! Great vid!
We do have pretty serious winter gales, here in the Shetland Islands, which easily top 100mph. Sometimes even up to 200 if it’s particularly bad (though that’s a rarity). We’ve personally lost three greenhouses to heavy winter storms – two glass & aluminium, once Keder sheets and Galvanised steel. The glasshouses were flattened, and the Keder one took off like a kite – but that was after a particularly wet winter had left the ground absolutely sodden and it wasn’t cemented in. Those were before Polycrubs were available. You see lots of them here, and they all stand up to the winter gales incredibly well, so I think that’s the route we’ll be taking too.
Hi Tanya That looks amazing! I live in the biggest “greenhouse” area in Canada with thousands of acres under glass or plastic. Tomatoes, Cucumbers, Peppers, Strawberries, Lettuce and of course Cannabis are grown here among many other things. New builds in the area are usually 100 acres minimum. Not many are using glass or soft plastic most are using polycarbonate sheets like your Polycrub. For all the reasons you mentioned which are all very valid. But this area is amazing as I believe there are between 10 and 20K acres at this point (have kind of lost track) so there will be much you can do in your mild climate! Looks fantastic and Thank you for the article and looking forward to more! Mike 🇨🇦 🍁 👍
Hi Tanya, I have just discovered your lovely website, while looking for a tomato chutney recipe (which looks delicious), I was amazed to see you standing in a Polycrub, and after perusal a couple of your articles, found this one. Firstly congratulations on your Polycrub, you are going to love it, I can guarantee it. I am a Shetlander and have lived here all my life. Growing fruit and more exotic veg is almost impossible here due to our very wet and windy climate. Owning a Polycrub in Shetland is a game changer. Driving around Shetland, you see them everywhere. We have had our one in 6 years. Bought originally for my disabled Brother and now 90 year old Dad, we hoped both would enjoy it, so built raised beds and s seating area in one end. I have inherited the Polycrub now as the carers didn’t have time to work in it, and I love it. I would recommend you install electricity into your crub, both for lighting and also having plugs. We have 3 windows in one end of our crub, all which open, and a stable door at the other end, which opens inwards. I have heavy fish netting curtain which I can pull across the door opening to keep out cats/birds etc. whilst having the door open. Beware of pests which will more as likely move in, vine weevils greenfly and earwigs. I have a large water but inside, but have to fill it regularly from an outside tap. It would be better if you could collect rainwater to fill it instead. And keeping the crub watered in summer can be a huge task, an irrigation system would be wonderful.
Tanya, Quickest, easiest way to tackle the doors is to take the existing latch hardware off the rear doors and move them to the inside; this solves your solution of needing to open them from the inside and means you also have a quicker escape route of you ever have an issue where you can’t get to the other doors. To hold the doors open, yes a lovely latch would be nice but a couple of eyelets in each door and the external wall will enable you to simply use gardening twine or wire to hold them open…. Or keep using the eco stone you have 😉 I’m super jealous as it’s literally the size of my backyard growing space. Best of luck; we can’t wait to see what you grow. Sammi x
It is a satisfying feeling to look at a finished polytunnel or greenhouse you have built or even also designed yourself, rather than from a standard kit. It will open up all year round gardening to you, especially in terms of winter salad leaves. I don’t suppose you know what 14 x 7m is in ‘old money’ (feet and inches) for those of us with a few more ‘miles on the clock’ (older) who still think in imperial measurements?
That is a great structure, over here polycarbonate is used for many things, outdoor patios covers etc but not seen anything like this. Here in Tasmania it would be an amazing addition be it small or large for home gardeners. My one question what about hail will that damage it at all? I love the barn doors, I hope they will provide adequate ventilation in the summer. Cant wait to watch how you develop the inside Tanya. Lucky you it is beautiful.
I think this will come into its own in the winter months, but I fear that it may be too hot inside during the summer months, even with the doors open. Shetland, where they make the Polycrub, is an extremely windy place, but it is also much cooler than the Isle of Man. Even in March your inside temperatures were over 30 degrees, it will be interesting to see what the temperatures will be like in July and August? A fantastic space though!
Simple solution for the back door. Put a latch on the inside for locking the two doors together. That way you can open the top part from inside and if you need to open the bottom door you can just reach outside through the open top door. Same time you’ll be able to open from outside when the doors are latched together.
Wow, wow, wow.. First time 2 view these. Beautiful, u r sooooo 4tunate. Just a thought but don’t 4get 2 leave some space at one end for a couple of chairs and table. 2 b able 2 sit inside with a book and cup if tea with a friend. Also I’d plan at least one side 2 have higher shelves 2 sit potted items on and pretty extra pots, etc.. U cld still have beds on lower under the shelves. Love 2 see some hanging pots too. Pretty lights? Can’t wait 2 see what you come up with! Will you set a fan up at one end 2 help push air through? It’s going 2 get extremely hot with no roof vents. Be so careful that the kitties don’t get trapped in on a hot day, they cld suffocate from high heat.
Beautiful Polycrub circulation fans would be something I would get before ever putting any plants inside unless that poly doesn’t allow it to get as hot as other greenhouses mine gets up to 110 very easily on a 75 degree fahrenheit day so on hotter days it can get hot enough to kill plants and pets so you may want an escape door for your kitties you will be able to grow so much food and flowers in that Polygrub happy gardening.
WoW, that is truly a thing of beauty and function! This is the first article of yours that I have come across and you and it are definitely creations of sculpted and poised beauty! Heh. – not to mention, very edifying! I guess the YouTube Skynet algorithm has deemed me worthy now to be exposed to you. LoL… Ya never know what’s REALLY going on with YT! Anyway, I’m over here in the US and we’re buying acreage in the middle of the country around the border of the South & Midwest (as much as we can possibly afford!) for a self-sufficient homestead (as the country slowly {rapidly?} spirals into collective madness and possibly civil war or collapse… It’s true- you may have already noticed… (Canada is worse as it inches toward totalitarianism & dictatorship…)) and we’re going to go the polycarbonate route to grow in all four seasons too. I’ve had it up to HERE with changing plastic coverings! 35 years for the polycarbonate? WoW! It’s so beautiful too and with the insulative properties of a double wall! Even if it’s expensive it is worth that. Where we’re buying, it’s a moderate climate with 3 nice seasons and one resembling Hades with the heat and humidity. There’s a price for everything and a brief but hot and humid summer is the price we will pay for 9 other (to my mind) wonderful and pleasant months. I’m probably going to design & build some polycarbonate greenhouses with the Gothic Arch form (although your half-round is extremely sturdy too) and a number of combined innovations (everything must do double or more service!
Great design. The cost is just okay though. The building is about $5,000 and doesn’t include S&H cost, grade costs, or build costs. Polycarbonate is great, however double polyethylene has a comparable R value or insulated equivalent. The building being put into concrete is smart and protects your investment. I can build a post framed greenhouse for much less though, with polycarbonate and or polyethylene. A 10 ft by 40ft is $6,000 total with labor in the states. That’s 2 doors, polycarbonate ends trimmed out, and double polyethylene. For about $2,000 more it can all be polycarbonate. The polycrub is the best design I’ve seen next to mine. The main difference is I can customize my building for any need. I only build local so it’s not really available to everyone is the down side.
I have no appreciation for websites that sell a product, but doesn’t list the price. The only way to get a price is to talk with a sells person. That makes the decision for me. Can’t tell me what it costs? Then you must be over charging. Shame. Looks fabulous! Would have lived to possibly had one myself. That’s OK. Other products tell price upfront. I can deal with that!
One of the most depressing garden jobs I have is looking around for cat faeces after I’ve had my morning coffee in the garden. My space is much smaller than yours so I can keep on top of it. With large spaces like yours and multiple cats, do you try to get the faeces out of the food beds or do you accept it and let it rot down among your crops? Maybe you pay more attention to the ground around root vegetables and low hanging crops prone to splashing during rain and less to climbers like tomatoes and beans where the roots of the plants are drawing in water that’s been touched by the animal soiling but the edible parts are not. Sorry for the off-topic but the cat in shot made me think back to the time I lost today to a cat diarrhoea spread across the lip of one of my raised beds.
