Hot water faucet

[Orchidbyte]

A few months ago I installed a hot water line with a shut off valve fed into my cold water pipe/faucet outdoors. I wanted to water greenhouse in morning like always do, I always felt bad because greenhouse is warm and cold filtered water is very cold, almost freezing.

Now I can mix cold and hot to get a good temperature, I have noticed the plants and orchids respond to the warm water showers, i.e. More root growth, better winter growth and flower.

Has anyone else done the same?

Am i the only plant/orchid nut crazy enough to run hot water outside?

Thank for any replies
