Hello, ice cubes are much too cold for any plant. I read online to soak the orchid pot 30 minutes for the mix to absorb the water. Orchids attach their roots to the mix as they grow. In nature bug waste is used as fertilizer by the orchids, I started using my fish tank water and my orchids are starting to bloom! I also have my orchid pots in a larger container with water, this helps the roots stay moist and grow toward the moisture. Best of luck!
Yes or you can put your pots in a basin of water and gently pour your water/fertilizer mixture over the chips allowing them to soak the chips for a few minutes. Remove the pots from the water and allow any excess water to drain from the bottom of the pot. Be careful not to allow water to sit on the leaves.
