The pre-wet substrate is placed in the tray, and the surface of the hole is scraped from one side of the tray to the other side by a scraper so that each hole is filled with the substrate, and each cell should be clearly visible after the plate is loaded(128 cell seed starter trays). Place the tray filled with the substrate on the seedbed and carry out the pressure point. The depth should be 2-2.5 times the diameter of the seed.
To this end, the seeds need to be disinfected before germination to reduce the original source of infection(plastic nursery pots). The common methods of disinfection are: first immerse the seeds in cold water for 1-2 hours, then pack the seeds in gauze every 50-100 grams. Fasten into a semi-boiled water at 80-90 ° C with a string. Do not wrap the seeds in the gauze. When you are immersed in all the seeds, extract them quickly(seed plug trays wholesale).
