Traditional clear greenhouse plastic is capable of diffusing 23% of UV light with a total light transmission rate of 90%. This style of greenhouse plastic is great for plants that need lots of direct sunlight.
If you put a piece of plastic wrap in front of a flashlight, there would be little change because the light would pass through. Plastic wrap is transparent and allows light to be seen through the other side. Other objects may block or reflect light, but something clear would allow it to pass.
At that size, it's easy to imagine how plants could absorb plastic particles, but there are size limits regarding what passes through cell walls. Generally, healthy adult plants only absorb materials 3–4 nanometers in size, which is even smaller than a virus.
As regards plastics, they tend to allow light to pass through although it progressively gets absorbed, just like the way glass or even water will absorb light if it has to pass through more than a few centimetres or so of thickness.

These materials absorb one or more frequencies of light and transmit what is not absorbed. Examples of transparent items include plastic wrap, soap bubbles, clear glass, and some plastics. Objects that do not allow light to pass through them are called opaque. Opaque objects cannot be seen through.
Studies have shown that plastics generally have a negative effect on plant development, which might manifest in alterations in both germination and root or shoot growth. These changes, however, depend on several factors, including the environmental conditions, plant species, and plastic concentration.
If your pot is going to be on the street then you need to make a top protective layer. Take acrylic varnish and cover the pot with ribbons and beads. This will secure the top pieces and prevent the paint from cracking or fading in the sun.
Plastic can be used to protect plants from frost, but it's not the best or most effective material. In fact, the horticultural experts here at Green Impressions actually recommend against it. Plastic materials such as vinyl and traditional camping tarps aren't breathable, causing moisture to get trapped inside.
Plastics can change the soil chemistry. Films could increase water evaporation, drying out the soil. Plastic surfaces could allow toxic substances to accumulate in ways that they couldn't in organic soil.
Type 4 - Low-Density Polyethylene
The plastics that are already used for food storage tend to also be safe to garden with. Like it's older cousin HDPE, LDPE plastic is very safe in a wide range of temperatures and can even be used in the microwave. Conclusion? It's a good choice for the garden.
In plastic wraps sold in the US, polyethylene is the main component. It is a structure with only single bonds, so it should not absorb any UV radiation, as it has no conjugated double bonds. However, some of the UVB radiation was blocked, suggesting a contaminant or reflection of UVB radiation.
Plastic is often classified relative to light penetration because many plastics possess unique properties. There are 4 different types of light penetration. It is much easier to differentiate them when their properties are side by side. Opaque – Light will not pass through.
Explanation: When light passes through a plastic bulb, it can behave in multiple ways. It can be reflected off the surface of the plastic, absorbed by the material, or transmitted through it. Reflection occurs when light waves bounce off the plastic surface.
Plastic – Plastic is typically lightweight and easy to use while covering your plant materials. However, if it is laid directly on top of plants, there is no insulation and this is where damage can occur. In addition, heat can build up under plastic if the temperature rises and the sun is out.
Despite its convenience, there's one item you should stay away from to cover your plants. If you're looking for tips for protecting your plants from frost, avoid using garbage bags as plant covers. Trash bags are not the best protection against frost damage, primarily due to their material.
Zip bag closed. Place your closed baggy in a window that receives a good amount of sun (Bean side up). You can also tape your baggy to the window (Bean side out). For the next few days, check in on your plant in the window to see how seeds produce growth!
Researchers propose using plants as eco-friendly tools to absorb and degrade micro- and nanoplastics in the environment. Credit: Igor Son / Unsplash. Plants can absorb micro- and nanoplastics in their stems and roots, raising concerns about how natural ecosystems cope when plastic particles invade.
It may be better to use plastic as a liner on the inner sides of a raised garden bed, but use a more permeable material for the bottom, such as landscape fabric or wire mesh. Keep in mind though, that you want to know the specific type of plastic that is being used if you are growing an herb or vegetable garden.
Limited Airflow
Plastic walls restrict air circulation around the root zone. This can impede healthy root development and potentially create an environment for harmful bacteria and fungi to thrive.
Opaque bodies do not allow light to pass through them.
The transparency of plastics refers to their ability to allow light to pass through them. As a result, the objects behind them are distinctly seen. This desired optical property is what sets transparent plastics apart from opaque varieties.
Acrylic generally has superior optical properties compared with polycarbonate. It offers good light transmission, diffusion of LED hot spots, and is easy to fabricate. Acrylic sheet is used for a wide range of lighting applications including: Commercial lighting fixtures.
