San pedro cutting question

Hello all, quick question here.
A few months ago, I cut the top 6 inches off my san pedro cactus to save as a cutting to re-plant when I harvested the majority of the body.
I lost this cutting until yesterday, and while it's slightly smaller then it was, it's still very green and appears to look fine.

Now my question is, could I lay this cutting down in the perlite/cactus soil mixture to increase my chances of this little guy taking hold? or is my best shot with a vertical planting?
thanks in advance

Seeing as this species grows naturally in a vertical position ........ Although keeping a cutting dry for so long is probably something that few of us have any experience of.

Cutting looks fine. If it's got a good callus and it should by now I would plant it vertical. It will root cactus always roots.

I'm aware it grows naturally in the vertical position; however I had read somewhere that planting a cutting horizontally may produce multiple pups. I didn't know if because of the cuttings small size if it was a viable option.
thanks for the quick replies by the bye

Personally, I also strongly support the vertical planting methods... They will grow pups (sometimes multiples) from a horizontal position, but I honestly don't know a piece that small will benefit from a horizontal planting. And yes, after just hanging around cut for that long, it will still be fine. I've had cuts sit around for months at a time with no problems. They'll root without missing a beat.
Short answer- plant either way, just about boils down to personal preference.

It's a matter of preference but most experienced growers will tell you they grow better vertically.
Laying them sideways effects how fast the hormones are transported through the cactus from the tip to the roots. Log propagation is similar to "low stress training" cannabis plants and produces an increase in cytokinins which typically leads to more chloryphyl production, more pups, and cell division.
That sounds like a win-win situation but it causes a reduction in auxins which are responsible for root production. They are even used as rooting agents.
The reason why experienced growers tell you to go vertical is because causing a shift in hormones with a cutting is risky enough but causing a shift towards cytokinin expression is extremely unwise. It will downplay the auxins and stall rooting.
Once the vertical cutting has taken ahold of the soil and formed a good root mass cut the tip of the cactus and it will stop the production of auxins almost completely. After the tip has healed it will start new pups and the mesophyl will become denser from increased chlorophyl production.
It's always better to keep it natural and upright. When you need more pups cut away the meristem tip and it will branch out naturally 
What light are they getting? If the tip was that skinny chances are they need more light. Etiolation can be caused by several things but light is normally the culprit.

Wow!

I've never heard/read the scientific explaination of what is going on when you plant log style! Thanks for sharing the knowledge.

No problem! I got super into hormone manipulation when i had a few cannabis plants as a teen. To be brutally honest i gained the idea and a lot of knowledge from Jorge Cervantes books on cultivation.
Cannabis growers use low stress training, topping, and whats called monster-cropping to disguise the shape of the plants, create a more even canopy for light distribution, and encourage lower lateral colas to develop as much as the primary meristem.
I also really enjoyed this theory of plant hormones: http://www.planthormones.info
It explains the complexity of growth regulation in plants but it's a long read.
