Switching over to S/H?

[HiOrcDen]

So, I would just like to get an idea of the possible advantages of switching over to S/H culture, as well as any possible drawbacks.

Can S/H be used for all species?

Does it at all accelerate the growth rate of any species?

I understand that it allows for less frequent watering. However, is there a way to automate watering, in case you want to take a short trip? Can you do this outdoors, if the pots are held stable?

Are there any other advantages, &/or drawbacks?

I will attach a pic... I would like to know,if this is indeed a S/H pot suitable for orchids?
