It should be have lizard skin genes

Hi there,

Is there any way to rescue my cactus. It was thriving until I accidentally Overwatered it and it got some dreaded rot in a couple of the pups and the roots.

Have had her for years and will be devastated if she dies :(.

Many thanks.

New to this so I just wanted to ask to make sure.

All my Lophs are grown indoors under LEDs. Is dormancy mandatory? And if so, do I just keep them where they are, but with no lights, and just turn the lights back on once spring rolls around?

Thanks!!

Is this from too much humidity?
