The deeper the pores, the more air there is in the matrix, which is beneficial to the gas(plug trays), the salt and the gas, which is beneficial to the growth of the roots. The matrix must have a depth of at least 5 mm to have gravity, so that the water in the matrix seeps, and the deeper the air enters the hole, the more oxygen is contained. The shape of the hole is preferably a square trapezoidal trapezoid, which is advantageous for guiding the root system to extend downward(flat plastic tray), instead of winding the inner wall around the hole like a circular or vertical side hole.

(cheap sprout growing trays wholesale suppliers canada)The smaller the trays(propagation tray), the more sensitive the plug seedlings are to changes in soil moisture, nutrients, oxygen, pH, and EC values. Deeper pores provide more favorable conditions for drainage and venting of the substrate. Some plugs also have venting holes between the holes so that air can flow between the plants. Make the leaves dry, reduce the disease, dry evenly, and ensure the uniform growth of the whole plant(seed starter trays). The smaller particles of vermiculite act to increase the water retention of the matrix rather than the porosity.
The color of the tray also affects the temperature at the root of the plant(cell trays). Generally, the black plug is selected in winter and spring because it can absorb more solar energy and increase the temperature of the root. In summer or early autumn, it is necessary to change to a silver-gray plug to reflect more light and avoid excessive root temperature. White trays generally have a high light transmittance, which affects root growth, so white trays are rarely selected(nursery plant pots). Of course, white foam trays can be exceptional.(cheap sprout growing trays wholesale suppliers canada)
The use of safer quaternary ammonium disinfectants can also be used in the sterilization and algae removal of irrigation systems to avoid the growth of bacteria and moss(black plastic plant pots). It is not recommended to use bleach or chlorine for disinfection because chlorine reacts chemically with the plastic in the tray to produce toxic substances. To increase the drainage and permeability of the peat matrix, choose to add perlite(large plastic terracotta pots). Conversely, if you want to increase the water holding capacity, you can add a certain amount of small particles of meteorite.
Ideal moisture capacity(gallon plant pot); good drainage capacity and air capacity; easy to re-wet; good porosity and uniform void distribution; stable vascular bundle structure, less dust; proper pH 5.5-6.5; with appropriate nutrients, able Ensure nutrient requirements before cotyledon expansion; very low salt levels, EC is less than 0.7 (1:2 dilution method); matrix particles are uniform(plastic grow pots); no plant pests and weeds; the quality of each batch of matrix remains the same.(cheap sprout growing trays wholesale suppliers canada)
Fill the tray substrate with the following points: The substrate should be fully wetted before filling(gallon nursery pots). Generally, 60% is suitable. Hold the substrate with your hand. Without moisture extrusion, loosen the hands and become a group, but light. The substrate will spread out when touched. If it is too dry, after the watering in the future, the matrix will collapse, resulting in poor ventilation and poor root development(square grow pots). Otherwise, the pores with less basis mass dry faster, which makes the water management unbalanced.
