How to take care of a mother?

Hey guys, I’ve got a couple clones here that I want to grow and keep in veg as mother plants. Is there anything special I need to do or do I just keep running 18/6 light schedule? They’re in soil. Cheers

A lot of folk keep them minimal as in bonsai and then when you need them, hit the big lights, boost them up and take cuts, depends on your lifestyle/space/grow cycle. Obviously keep them veg cycle and healthy for as and when you need them.
