Question about mother plants?

How long can I keep a mother (from seed) in veg?? And what is the best light schedule for her??

As long as you can keep the mother alive you can keep.her going, I believe any light schedule that gives more then 12 hours a day will do it. I seen a few folks on here saying they use a 14/10 schedule or the traditional 18/6.

@Tdave1211 ive heard of a 6 year old mother plant that was repoted over and over and roots cut back at certain times hope that helps

I’ve heard 24 hrs on is the best for a mother.
With veg nutes

I would go with @Ds401 on light times a mother plant in right environment can survive for years if taken care of properly
Good luch @Tdave1211
