What plants would a kerosene heater be bad for?

I have read here that heating my greenhouse with a kerosene heater would be bad for tomatoes and "other plants". What would those other plants be? Thanks for answering.

I would be interested in knowing this as well. Have tried to look it up online. It's been so cold here this winter I've had to use my kerosene heater more than ever before. I'm seeing some effect on my lettuce leaves, but nothing really noticeable on anything else....my greenhouse is full of herbs. I couldn't find anywhere that said that the plants would take in anything harmful from the fumes as it is a concern to me. Haven't started my tomatoes yet. Once it gets above 30 degrees outside my little electric heater will be enough. It's supposed to be warmer this weekend, still low night temps though. I'm hoping this arctic cold will leave before I get into starting my veggies!
