Different from other cacti, I have given seedlings (not mature plants) some moisture during winter. In my greenhouse I sow seeds in small propagators seated below some thin see-through shading cloth. I grow Strombocactus disciformis seedlings in the same way. I use a thick cactus spine, rounded in the sharp end to carefully brush algae away from the seedlings in ther pots, if it occurs. This may seem strange, but it works for me. And I do not think too many people have success sowing this species.
Avoid burning sunshine, mature plants may tolerate lots of sun in northern climates (like in Norway), but then ventilation is needed.
