When you make cuttings what do you find encourages the most root growth? I was told to put cuttings in a dark warm area and it seemed to do the trick, I am not sure if that is the case with all cacti though. Any thoughts on this would be greatly appreciated.

Put in warm but not dark, just in shade or obscured sunlight. Cuttings have to feel the moisture in the substrate below. It may take several months or more.

Once they have rooted in the shade or filtered sunlight where would you put them then obviously you don't want them to etoliate? Obviously in the summer they would go straight outside or slowly acclimitise them to going outside but what happens during the winter would you either put them in the dark till winter is over or slowly acclimitise them to a grow light indoors?

I have no much growing experience with grow lights but these definitely will not burn newly rooted plants so go ahead any way. You can also put together (rooted or not) you cuttings with other plants of the collection getting some or any natural light and if you do not water them presence of roots doesn't make any difference. Sometimes mature cuttings even bloom.

Alternating between bone dry and moist seems to help stimulate new roots.

This may not be of interest here, since the majority of cacti wouldn’t be rooted in water but I found it interesting so I dare posting it nonetheless. I read a post somewere, were someone asked for advice rooting a Monstera cutting. Adding a Tradescantia cutting or more in the same jar as the plant one wished to root, would improve the chances and speed up the rooting process on the other cutting . Anyone who have heard of this or have tried it? I wonder if the Tradescantia cutting gives off some chemical ‘message ‘ to the other cutting and thereby speeding the process?
If so one could be tempted to belive this could be transferred to rooting in soil too?

Rooting hormone helps.

Or just buy some... it's not exactly expensive.

You'll never find any of that quality though. Manufactured the same day as you use it. Partially glucuronidated for better absorption by the plant.

No plastic packaging. No wasted gels or powders.

I'm very interested in this topic because I produce plants for sale. Rooting in some species can take months, and that is just wasted time in terms of production. I know that temperature plays a big part, and lower temps definitely slow this process.

I think it should be visible now.
