Let me know what kind of greenhouse covering you are using or planning to use and why!!!!!!

Thank you for clarifying covering materials. Excellent and concise. Thanks.

Thank you. great information. We live in N.W. Montana and on the side of a mountain getting more snow and colder temps, snow shedding, very short days into the winter but still wanting to grow at least 10-11 months out of the year. So this information is important for use. We are planning and will be building ours this summer 20x40 and unless something changes will be using double wall plastic inflated. Thank you again.

I built my first 11' x 14' poly tunnel several years ago using what I already had - a roll of 6 mil "visqueen" from Lowes. The skin lasted exactly 2 years, and it was great. I moved it and rebuilt it this spring and used the same material again for the same reason - it's what I had. The benefits of having any kind of greenhouse are so great that you really shouldn't put it off because you are waiting to afford something better.

FYI, My father built a greenhouse using corrugated semi-clear (tinted, summer temperature was too hot) corragated plastic sheets. We fastened the sheets to the roof timbers using corrugated molding strips like these from Lowes - Tuftex Wood Solid Roof Panel Closure Strip. Over the years only had sheets loosen up a few times. Installation wasn't too bad.

Thanks for this information 👍 I'm now another step closer to my greenhouse build 🥔🥦🍓🥕🍅🥒🍆🥬

nice, unbiased.....I use a double poly stretched over an aluminum frame.....the poly is easily replaced.I got it free, as it needed some work...some torn panels, some bent aluminum, but it has been functioning now for 2 years. Its a 10x12.

I bought a prefab greenhouse with single wall polycarbonate that was too hot in the summer and too cold in the winter (SE Montana). I had to move it on the property after two seasons that required taking it apart. I took advantage of the move to put it on a block foundation, add power, lights, and ventilation, and most importantly, covered the greenhouse with Solexx twin wall. I put the original single wall polycarbonate back on OVER the Solexx and secured it all to the wooden frame, much like the greenhouse at 08:30 in this video. I mostly use the 8x16 greenhouse for starting seeds for the main garden season, and growing greens like lettuce, kale, chard and spinach under domes for winter salads with supplemental heat from heat mats. I also. Have close to 100 gallons of water in 5-gallon pails and milk jugs for thermal mass. Today is sunny and with the outside temperature of 25 degrees, the inside temperature is 74 degrees at 1:30 in the afternoon. The low last night was 13, and the low inside near knee level was about 27 degrees ( I was tracking the air temp on the water jugs) The peppers and the eggplants that I held over from last season as an experiment, that were sitting on the heat mats are OK, but a couple that were not on heat mats got frosted, though if I had remembered to cover them, they would have been just fine. Again, looking at the greenhouse pictured in the video at 08:30, my door faces east the right hand side faces north. My vertical sides on the north side are insulated with 1” foil faced bead board, and the whole north roof is faced with aluminized Mylar bubble sheet. I am still working on improving the systems.

Can’t wait to cover mine.

I'm impressed by the amount of relevant information and the 'good energy' in presenting it - Thank's

I'm just planning on building a huge Greenhouse this here so perfect timing thank you.

Nice breakdown. Looks like polycarbonate panels are likely the best choice for my plans for off-house cold climate Winter solarium. I want to be able to the walls off in the Spring but leave the roof as a shade in the Summer. I may look into using the corrugated panels on top of the double walled panels as a way of protecting the roof from moisture, depending on flashing options.

Thank you for the great video packed with good information for us first time builders.

Great video Sir. I like your list of pros & cons of each material. Polycarb.-looks like it's my choice, until the single layer-corrogated plastic comes in 2 layers. Keep it up, post more for beginners like me. Cheers, & Tx.

I use a corrugated Lexan in a Greca pattern from Amerilux. It is called soft lite and disperses the light so you do not have any shadows and it penetrates the canopy at multiple angles so you obtain much more growth lower on the plant. I used it on our first greenhouse and am now installing it on our second greenhouse which we are building.

Now this is what I like to see, everyone can get behind this and construct their own greenhouse 👍🏽👍🏽👍🏽

I love all these videos. Great info to help in the cold NH climate.

Thank you... I'm planning a new greenhouse this fall and you offered several suggestions I maddy be using... Good luck... ~Bear

I was even thinking about using stretch wrap. I've seen pallets sitting outside covered in this stuff and it lasts years. It clings to itself and you can make several layers wrapped around whatever frame you have.

Simple Tek,. Great video and keep it up. Viewers love options and you are proved them. Thank you.

Once again, great info. Thanks!

Imagine the weather in the area like wind storms, hail, etc. would determine what material a person would use. Recycle old windows or use more than one option within budget until afforded then wearability can be monitored like a test to see what would be best. Glass is so beautiful! Did not know there were so many options until now.

A lot of rain this summer in my zone. I need to make my choice soon. Your video helped me a lot. Thanks!

Thank you for helping me with my school project, and your videos are enjoyable to watch

great video! I'm making my gf a greenhouse for her birthday. this helped me a lot! not sure what I'm gonna go with yet but i cant wait!

Very useful information. Thank you sir. Have a wonderful day.

Thanks for the information and happy growing👍👍👍

The last you talked about is easy place a spacer on the first layer and block off the ends. Just stager your spacers and that will help warm air flow between sheats.

Thanks for sharing your valuable information with us, 👍

Excellent information! Thank you for sharing!

Thank you for the information! I'm looking at converting a wooden gazebo that needs the roof (shingles and some corrugated panels) replaced anyway. I'll look further into Solexx as well as double layered polycarbonate.

2 years ago I used the corrugated panels on the outside of a framed greenhouse. Sealing all seams with silicone. The first summer day with low humidity, I used insulating 3 mil clear plastic and stapled to the inside of the frame. with the clear tape to seal all edges. I used a clear silicon exterior caulking adhesive and staples to attach. This seems to be working well. The air gap is the width of the 2x4 I have no idea what the R value is. I think because there is no wind stress on the plastic, it still looks brand new. Because I waited for the low humidity, I am not having any discoloration between. This is only on the sides, as I use the ends for ventilation. I am still working on having both on the ends. Hope this helps. BTW it was tedious to build, as I matched the hills and valleys carefully on the ends, so they could be completely sealed with the silicone and not allow moisture between the layers.

Love this information it brought up the option of using Solex again. Thanks, show us more like this.

I have 2 greenhouses covered with a single layer of poly. In Tn i can grow lots of cool weather crops in the fall, winter and spring, without heat. If it makes it to next April it will be on 8 years. If not i will replace it. I bought the poly in 2013 and bought a long enough roll to cover the first one twice for about $200.00. I bought it from Amish in South West Ky in Elkton, KY. They have a high volume of sells so they can sell cheaper than some people.

I used the big box store corrugated panels for a chicken coup. Got clear & smoke panels both for testing. Placed a clear then smoke alternating over sleeping/roost areA. Idea of smoke was to draw warmth from winter sun. Worked very nice n chickens liked it & I was happy, provided winter sun to get girls up n moving n happy. I'd reach in & be quite nice even on 20° days. We get snow & of course would always melt off of smoke colored panels first. After 3-4 years , one day had a hard hail storm. Some hail measure 3/4" in width. The clear panels it punched a few holes in, (not many) & next panel which was smoke received No holes. Both panels were the same thickness and size installed same way. The smoke survived with out holes, but clear not as well. Realize in a green house only clear be used. Just what I learned.

I found your video very interesting and informative as well as very well laid out. I wish more documentaries that try to teach you something were so well done. I just subscribed.

Good video. Need to learn how to keep plants in winter. Moved from CA to Texas. It’s a lot different and I hate when my plants die. So this information is very needed currently.

Thank you for sharing this valuable information.

Thank you for this informative and interesting video.

Thank you for the video. Very interested in various greenhous/year round growing options.

Very informative. Thank you for sharing!

Thanks for the video! I'm looking at corrugated plastic panels, but what's best: clear? smoked? blue tint (cheapest)? with embedded fiberglass mesh? Not sure of what the benefits are. I've been using the clear on a few lids for raised beds but they seem to get brittle and crack after a few years.

Thank you! I was looking for just this info.

Thanks for the great information!

i built a dyi 8x20 greenhouse .I bought a ''used'' 30' clear pool cover , its like buble wrap and Its strong. I also used , ''used'' patio doors as the window around the sides. Last summer and into January the plants were great. How long it will last here in Canada is yet to be determind.

Hi there I suggest doubling up corrigated sheets using rolls of self adhesive neoprene which can be bought in a variety of widths and thicknesses. small pieces off the roll could be used as spacers mid sheet and run the roll full width to end seal the doubled sheets

Corrugated panel is the way to go. Great stuff! I'd love to incorporate both corrugated panel and inflated poly into a structure.

I covered my wife's DYI 10 x 9 greenhouse 20 years back with corrugated fiberglass panels. It was great then. We moved from SC to TN and brokedown house and used panels again when raised. Moved again in TN, discarded panels at that time, but they were still good. Have just re-assembled frame of house this month and will go back to some corrugated panels on sides and poly on top. Thanks so much for you channel.

You can get foam profile inserts for the corrugated sheeting that will allow you to achieve an air gap between two sheets. It is used for draught and vermin proofing, vibration and noise control, air and weather sealing and watertight sealing.

Corregated panels are pretty common in some parts of Montana. I was thinking of affixing poly on the inside spars to create an air gap.

Try building with two layers of clear corrugated sheets. Build similarly to house leaving air space in between. Where the outside is horizontally hung and the interior is vertically hung it seemed to baffle the cold air. I also used sticky window foam insulation on overlapping edges that I was screwing together on exterior walls.

Thank you for sharing brother.

Great video, excellent informaton. Thank you!

If you want double wall corrugated, use 1”x1” wood spacers between the panels to provide the air gap. That should give triple the strength without making the panels excessively heavy.

Great information, thank you!

I used corrugated, I didn't know it was a thing.. 3 years in so far so good. We have lots of snow

Thanks! The breakdown you gave was exactly what I was looking for.

Wonderful video, very informative thank you.

Can't wait to try it....

First off, I think I've learned a thing or two watching your videos. Thank you. I am wondering if it is possible to lay fiberglass over a geodesic dome and sand and polish smooth to a close to glass like transparent finish. I would really like to hear your thoughts on the possibilities if it's possible.

You're awesome man! Love your channel so much.

Great information. Thanks

Thank you for your great greenhouse news I'm planning to build me 1 with plastic seats for Cannabis grow

Thank you for making this. I suggest for your research on corrugated plastic panels and a space between layers, to try experimenting with a combination of drilling matching holes in panels, stacking something like rubber washers for garden-hose connects as spacers in between, and for a pass-thru fastener using an aluminum pop-rivet. Inexpensive and easy. I have a growing/greenhouse project in my mind for the future to address current threats to our society's food security by being tethered to long, complex supply chains spanning multiple continents. A second job the panels can do is be used to recover the distilled water condensate where convenient. Best of Health to you.

just what I needed. thank you

Very useful, thank you.

Very much enjoyed video and learned a bunch

Hi we currently have double wall poly carbonate sheets. So far working great

I used corrugated fiber glass panels from Home Depot. Inside the greenhouse I put layer of pool covering from Amazon. Pool covering is cheap because its not though to be used for a greenhouse. Anything for greenhouse is expensive. It's very durable too. There's 4 inch gap between the panels and pool covering since the greenhouse is made with 2×4 lumber.

I always wanted to live in a Greenhouse. From this video I learned glass is best. Polycarbonate sounds 2nd best along with corregated panels or double layered poly.

Hello there love your Greenhouse material video

Very useful, thank you, sir.

Great information!

Great video, very useful

Just found your videos, very helpful, thank you! Hard to hear what your saying over the music on this clip but I appreciate the great information👍

Love it!

Commenting. I love this vid. I’m thinking of the corrugated option with an inside poly liner to create an air pocket.

Thanks for the advice

Hi! Hope you are well and love the videos. We are planning to building a greenhouse this summer using 16mm polycarbonate panels. I am aware that we need to tape/seal the top end of the panel but what do we do with the bottom end? Do we tape it with solid tape (same as the top end) or use the air flow tape and end cap that allows moisture to escape the panel? We are hoping to use the greenhouse in the winter months (living in Calgary) but are unsure of how to treat the bottom end of the panel as we want to keep as much R value as we can. Thanks so much in advance for your time!

Excellent explanations!

I have a question...my husband and I recently built a raised garden bed approx 8 x ten with tall sides to keep animals out, however we live in an area in which we get hail storms, can I use an opaque white tarp over my garden for any extended period? Will my veggies still grow under there if I leave it on for several days? This would be temporary until we have time to turn it into a greenhouse...thank you?

Thx for sharing ideas

Hi Im building a geodesic dome with wooded battens. Which glasing material should be used? Do you have any videos on how to cover a dome? Cheers M.

I built a hybrid using recycled sliding glass doors and Windows with a corrugated plastic roof. I did have to replace the roof after about 7 years because i it wasn't adequately supported and sequered and that caused warping in the heat. It also became very brittle and fractured as I was removing the old panles. The price was great and I figure most of the issues were do to used error.

Thanks for the tips

great video! lots of useful informations

Maybe it would be cost prohibitive, but if you wanted an air gap, for insulation purposes, using the corrugated plastic, you could just mount the plastic on the outside of the greenhouse frame as usual, and on the inside of the greenhouse frame. Personally, I like the idea of using a blower to blow air between layers of poly to achieve the same thing. I may have to try that with my small greenhouse.

I do think I need to use the local reg plastic roll , is 4 mm 25x 100 a good deal at 66.00 ? I'll b using steel rebar frame, feels like the steel is making a magnetic effects, any advise before i commit

Just a thought about air gap with corrugated plastic. What about corrugated plastic on outside and a poly roll sheet on inside of greenhouse to create the air gap.

thank you for making this video. My boyfriend family has an old carport and had a idea to make it into a green house but all i heard of is them using plastic but i want to make it more sustainable and wont brake easy.

I have a 6' x 20"wide path X 8' long behind my storage SHEAD and Neighbours chain link fence facing south. What construction material would you suggest for a starter greenhouse, for sprouting new plants in spring from the seedlings I started in the Crawl space under grow lights during winter here in southern On, Canada?

Thanks for the tip on solexx. Looks like they're the best :)

Excellent video

Great job!

Great video. Very informative.

I used corrugated panels clear and for the top I used tinted panels. It’s too hot inside 115-120 now I’m trying to cool it down. I just bought shade cloth for the top, I’ll see if that works. It’s cooking my plants. South Mississippi

I really like your channel and have learned a lot. I live in Michigan and am looking to build a greenhouse that I can grow all year round. I will be using a hydroponic system and wanted to know if you have any design resources for the greenhouse.

Thank you for the information.

With twin wall polycarbonate do you need to seal the open end sections?

Great info thanks!
