Using decorative outer pots

[StevenPDX]

I know it's best to use plastic pots and I am switching to all clear pots. The problem I have is that on plants with tall bloom spikes, then tend to tip over easy so I use an outer clay or decorative pot to keep them standing. I also have them on a bed of pebbles for humidity.
My question - is it best to take the plastic pot out of the outer pot or does it make a difference?
