Tips: What is the best seedling substrate?

The good substrate used in the process of using the seed trays to grow seedlings should have the following characteristics:

• Ideal moisture capacity.
• Good drainage capacity and air capacity.
• Easy to remoisturize.
• Good porosity and uniform void distribution.
• Stable vascular bundle structure, less dust.
• Appropriate PH value, 5.5-6.5.
• Contains appropriate nutrients to ensure the nutrient requirements of the cotyledons before unfolding.
• Low salt level, EC is less than 0.7 (1:2 dilution method).
• The size of the matrix particles is uniform.
• No plant diseases, insect pests and weeds.
• The quality of each batch of matrix remains consistent.

The function of vermiculite with smaller particles is to increase the water retention capacity of the matrix rather than the porosity. To increase the drainage and air permeability of the peat matrix, choose to add perlite instead of vermiculite. On the contrary, if you want to increase the water holding capacity, you can add a certain amount of small particles of vermiculite.
