| When catching the virus of cactimania, usually a secondary infection of sowing seed will follow. There are various reasons for sowing seed. First of all, there is the huge choice of genera, species, and varieties. For the most demanding collectors, seed suppliers may offer field collection numbered seed. Seed suppliers often have a much larger selection compared to the choice offered by the plant producers. Secondly, there is the lower price of seed compared to the price of plants. For most of the species, for a packet of 10 to 30 seeds, prices vary between 0,5 and 2 euros. In that way, within a couple of years, one can obtain a nice collection for little money. The third reason is the interest presented by a seedling coming out of the seed and developing its first areoles, its first spines, growing step by step from youth to adult form. A fascinating sight. | When catching the virus of cactimania, usually a secondary infection of sowing seed will follow. There are various reasons for sowing seed.

| Sowing cacti is a little more delicate than sowing tomato or bean seed. Why ? The main reasons for this are their slow growing and their sensitivity to fungus (melting of the seedlings which results in liquefying all the youg plants in a pan within a couple of days). For the first months, waterings should be applied carefully ; on the one hand enough to avoid the seedlings dying from thirst (at this stage, they only have very little stems and very small roots), and on the other hand not too much in order to avoid fungus development. That means daily surveys with a touch of ability and know-how. Sufficient moisture can be maintained and fungus development avoided by using a funcicide. However, that does not stop the development of alga, which theoretically are without danger for the seedlings but which does tend to choke them anyway. (Also, that does not avoid accidents such as forgetting to water or too much watering). | Sowing cacti is a little more delicate than sowing tomato or bean seed. Why ?

| **Soil :** As a basis, I use a good quality, fine earth bought in a shop, to which I add vermiculite (expanded mica), perlite or any other draining material, as well as possibly some sand. The important thing is to have an open draining soil. The presence of a quantity of peat does not matter as long as the seedlings are in the baggies. Once out of the baggies, it is better to repot the sensitive species into a more mineral soil. | **Soil :** As a basis, I use a good quality, fine earth bought in a shop, to which I add vermiculite (expanded mica), perlite or any other draining material, as well as possibly some sand.

| - | This is a kind of table-box, made by myself, from material I recovered here and there. It is simply made of 5 wooden boards. 2 upright (100x30 cm) making the sides and in between 3 horizontal ones (160x30 cm). Under each of the upper 2, there is a ramp of 2 fluorescent tubes of 1m50 (58W, but it is not necessary to get them that strong) so as to have about 20 cm between the upper side of the pots and the tubes. Better is to use 2 kinds of tubes, 1 Home light (red) + 1 cool white (blue), in order to get the light spectrum the plants need.
