I did have a lot of damage done to another Dracaena. It was a very large Red-margined Dracaena. You can see it in the first picture on the left behind the front rock. That pic was taken last summer and it was doing very well and happy in the GH until a week or so ago when for some reason the heater didn't turn on and we had serious damage to the plants. Second pic is how that Dracaena looked a few days ago. I cut the branches way back today in hopes that it will put out new branches.
