Ventless gas fireplace - effect on blooms?
I know there is controversy about vented versus unvented gas heaters for orchids growing in greenhouses (I don't have a greenhouse, but I do fantasize).
My question is - how about ventless natural gas fireplaces? The best place to display my phals in bloom is in the same room with the fireplace.
What is everyone's opinion - will the fumes degrade the blooms? Thanks!
