Sowing and germination

Sowing is carried out in the spring or in the presence of stable lighting all year round. A sterile fine-grained mineral substrate based on sifted cactus soil, fine sand, perlite and mineral chips is used. The seeds are distributed over the surface, lightly pressed against the moist soil and sprinkled with a minimal layer of fine sand or not covered at all. The crops are moistened from a spray bottle with a weak solution of potassium permanganate or biofungicide with the addition of a seed-safe growth stimulant according to its label directions, seed-safe growth stimulant, seed-safe growth stimulant, seed-safe growth stimulant or seed-safe growth stimulant. The container is covered with a transparent lid or placed in a greenhouse. Germination is carried out in bright, diffused light and a temperature of about 22-26°C, without direct overheating under the sun. The surface is kept moderately moist, but not wet, moistening is carried out only with a fine spray.
