Flat dimensions: 14 cm x 16 cm and 10 cm x 12 cm (including the border of the bags). Size after putting the potting soil: 8cm x 11.2cm and 5.5cm x 8.3cm (diameter by height); total quantity of 200 pieces. Environmentally friendly and biodegradable non-woven fabric material. You don't even have to remove the bag when you transplant it. Reduces the cost of recycling. Excellent water permeability and breathability. The delicate roots can be distinguished through the bags; moisture and nutrients are free to enter. Seedlings grow faster after transplanting due to the "air pruning" effect. The bags improve the survival rate of seedlings and ensure good plant growth. Prevents seedlings in plastic flower pots from forming tangled roots, root rot and damaged roots due to the impossibility of penetrating the walls of the container.
