This product is environmentally safe, non-toxic and lasts a very long time. This easy-to-use treatment has benefited both residential and commercial users for decades. Preserving and beautifying both homes and businesses. You can apply it to decks, fences, siding, and more!

ECO wood treatment is a proven wood preservative that gives all wood a silvery patina/high end aged weathered look and are able to be used in exterior or interior applications. ECO wood treatment mixes completely with water, no inert particles are added. A natural organic product with no harmful chemicals. ECO wood treatment is a member of United States Green Building Council.

Highly effective Wood Treatment

Highly effective: This no-maintenance substance will not wear off, will not fade, nor will it peel. Unlike other sealers and stains, Eco Wood Treatment migrates and covers the exposed wood as cracking occurs. In addition, the wood’s natural beauty is enhanced. For example, Fir wood will show a hue of dark brown to olive brown. After applying Eco Wood Treatment, it begins to penetrate deep into the fibers of the wood and eventually will enhance the natural wood color with a silver patina.

Chemical free: Eco Wood Treatment is a powder composed of natural substances from minerals. It contains no solvents and leaves no harmful residue in water or soil. It is safe to use on any structure that penetrates into the soil or into the water. Contains only 100% organic compounds.

Ingenious temperature-sensitive devices automatically open and close cold frame lids, greenhouse windows and even skylights throughout the day and maintain a constant interior climate, something impossible to achieve by manual adjustments. Requires no batteries or electricity, it starts opening between 55-95°F, depending on how you have adjusted the vent. Strongly recommended for all our polykeder season extenders, because it dramatically improves plant growth. Screw directly into wood. Use the Standard Vent Opener to lift up to 15 lbs.

26 gauge hot-dipped galvanized steel curtain with a baked-on silicone polyester top coat. Roll-formed guides of hot-dipped galvanized steel (16 gauge).  Self-lubricating wear strips on curtain prevent metal-to-metal contact and muffle door noise. Curtains are prepainted inside and out to inhibit rust. Hot-dipped, galvanized steel is painted with primer and given a tough oven-baked silicone polyester top coat, to provide the most rust-resistant steel door available. Heavy-duty bottom bar withstands the external elements. Full bulb-type bottom weatherstrip ensures proper fit along irregular floors.

Agtec Super Strength Clear Woven Greenhouse Film 12mil (per.sq.ft)
BTL Greenhouse SFeatures:

Extra tough 12 mil – thickness
Made from reinforced polyethylene (RPE).
Woven reinforced design resists extreme weather such as wind and hail.
Woven design is naturally diffused which prevents shadowing.
Retains over 80% strength after 7 years of direct UV light.
82% Light transmission for good growth.image1.JPG
Made in the Oregon, USA

This woven reinforced polyethylene (RPE) greenhouse plastic is designed for applications where super strength and stability is needed for your greenhouse. The woven reinforced design will stand up to the harshest climate conditions such as high winds and hail and the high UV stabilization will ensure many years of use.

The film is reinforced with strong scrim material that is fused into the multilayer design to ensure superb strength over ordinary non-reinforced plastic. This multilayer woven construction leads to a naturally even and diffused light inside the greenhouse which prevents shadowing and hotspots and ensures even growth throughout.

This film is perfect for areas with extreme temperature fluctuations as the reinforced design resists expansion and contraction better than regular poly which leads to less wear and a longer life.

This film is waterproof, rot and mildew resistant, and has outstanding puncture, pinhole and tear resistance. With proper care this film should last up to 7 years in most climates.

What is the frequency created by a Dome Greenhouse?

When talking about domes, the definition of dome greenhouse frequency refers to the number of pieces that each edge of the base figure is divided into in the process of triangulating its sides. For instance, we might start with a base figure of an icosahedron and divide each edge of each triangular face into 3 equal lengths. Those new points are connected to divide the original triangle into 9 smaller triangles. Since the original edges were divided into 3 parts, we call this a 3-frequency dome. The frequency is commonly abbreviated as “v”, so a 2-frequency dome is called 2v, 3-frequency is 3v, and so forth. The higher the frequency the more curved and sphere like the dome appears.

Explaining Dome Frequency

One of the first thing you read about when learning about geodesic domes is the term “frequency”. It’s quite simple to understand, actually.
Think of geodesic dome greenhouse frequency as density. The higher the frequency, the more struts are used. In real life this means there are more triangles in the same dome.

Look at the image below. The same base triangle is divided further every time you increase the frequency.

The dome greenhouse frequency indicates how many times each side of the base triangle is subdivided. For example frequency 3 means the base triangle is divided into 3 sections (or triangles) on each side.

Frequency pattern

The “base” triangle of a 3V has 3 subdivisions on all sides

SO WHY USE DIFFERENT FREQUENCIES?

The answer is two-fold: first the higher the frequency, the rounder the dome becomes. Second reason is strength of the structure.

The average dome greenhouse for instance is more than adequate with a 3V frame. In cases for large domes or homes, 4V,  5V or 6V are often chosen when constructing very large domes and for their resistance to snow and wind loads.
