With the done & dusted propagation and cloning sets we offer attractive starter sets for plant breeders. For the propagation of seedlings we recommend to insert those into peat soaking pellets or potting compost. The priming on tissues is a vast stress factor for germlings. For cloning plants, mineral wool suits good but it works with all the other propagation substrates, too.
By all means, it is important that the climate is right. With our sets and a good instruction that should be no problem.
