How to melt plastic

Intro

Melting process and temperatures depend on the type of plastic.

For safety, people recommend face mask. I just hold breath however.

Another safety measure is googles. Eyes are very important.

Temperatures

Need to be careful to prevent overheating (burning).

Temperatures are as follows:

Polyethylene: 130-140 C


Ways to melt plastic

Heat gun

Good to bend hard plastic. Under heat gun, it becomes very flexible.

Iron

Good for plastic film (wrap). 


Oven

Don't use the same oven as for cooking food. Plastic particles could be poisonous.


Fire

With fire, there should be a layer of additional metal can between fire and plastic per se. Otherwise plastic could burn.

Planting at home

Temperature

Most plants will do best between 24-27 degrees Celsius.

During night time or when lights are off the ideal temperatures are between 21-24 degrees Celsius.

Most can't handle temperatures below 10 degrees at all.

Plant damage might already happen with temperatures below 13 degrees. A few might be able to temporarily tolerate chilling temperatures but that doesn't mean that they really enjoy it!

However some plants can grow in cold weather:

  • Kale
  • Collards
  • Carrots
  • Turnips
  • Leeks
  • Ğ¡abbage

Plants to grow at home

Chilli peppers
Tomatoes
Garlic
Peas
Cabbage
Cauliflower


Lighting

A minimum distance of 4-5 inches is recommended between LED lights and plant leafs.
