You might have the question in mind “Is growing in plastic containers organic?” The simple answer to this question is, of course, yes. Plants can be grown in plastic containers safely. Durability, lightness, flexibility, and strength are advantages of growing plants in plastic containers. Plastic pots and containers are a good choice for plants like moisture or those of us who water from time to time. They come in various rainbow colors and are usually made of inert materials, usually recycled materials. 

However, this is not always the case. Recently, with people’s attention to plastics containing bisphenol A (BPA), many people wonder whether plants and plastics are a safe combination. There are many different opinions on the use of plastics in food cultivation. Most commercial gardeners use plastic in some form to grow plants. 

There are plastic pipes for watering plants and greenhouses, plastic for covering plants, plastic for crops between rows, plastic mulch, and even plastic for growing organic food. Although this has not been confirmed or denied, scientists agree that bisphenol A is a relatively large molecule compared to the ions absorbed by plants, so it is unlikely to enter the plant itself through the root’s cell wall.

Expert Tips: Biodegradable plastic is good for the environment because it decomposes and disappears over time. But please remember that anything decomposed will be transformed into other chemicals. It is always essential to understand which chemicals are produced in the process. They may be more toxic than the original plastic.

Expert Tips: Some types of plastics have been classified as food safe. These are No. 1, No. 2, No. 4, and No. 5. These plastics are classified as safe plastics because the chemicals they release are either not very toxic or not toxic at all. If they are safe for food storage, they should be safe for food cultivation. 

  • Make Sure That Your Plastic Container is Not Overheated 

Especially when the plastic is heated, it will release potentially harmful chemicals like bisphenol A, so keep the plastic cool to reduce the risk of chemical release. Keep plastic containers away from intense light, and choose light-colored containers as much as possible.

  • Use Pot Soil with a High Proportion of Organic Matter

Potting soil that contains a lot of organic matter maintains flexibility and keeps plants healthy, and acts as a filter system to help capture and collect chemicals and reduce the number of chemicals that reach the roots.

Expert Tips: Plastics release chemicals into the soil, which plants absorb. Most of these chemicals have very little content and are considered safe.
