Mismatching is the problem in growing materials. I wonder why they did not use the same crystal to grow the sample. For example, GaN is grown on Al203, why not take GaN as the seed?

A substrate is necessary for plant growth because it provides essential nutrients and physical support for the plant. It also helps to retain moisture and oxygen, which are crucial for the plant's survival and growth.
There are various types of substrates used for plant growth, including soil, sand, peat moss, vermiculite, perlite, and rockwool. Each substrate has different properties and is suitable for different types of plants and growing conditions.
In some cases, a plant can grow without a substrate, such as in water or using hydroponic systems. However, a substrate provides a stable and nutrient-rich environment for the plant to thrive, making it essential for most types of plant growth.
The substrate can significantly impact plant growth by providing nutrients, water, and physical support. It also plays a role in the aeration and drainage of the plant's roots, which are essential for healthy plant growth.
Yes, different types of plants have different growing requirements and may require specific types of substrates. Some plants may thrive in well-draining soil, while others may need a more water-retaining substrate. It is essential to research and choose the right substrate for the specific plant you are growing.
