well the thing with live plants in an aquarium is that you want to give them optimal conditions so that they can out compete algae for nutrients. With actinics, the light that they provide is not very useful for the plants in the tank, but some algae can use this small amount of light to cause problems. So, I have seen plant tanks with actinics (with normal daylight bulbs)do ok, it is just not a great thing to do. especially because of the light intensity of pc
But yes, pc
's are great for plants as long as you get them in and acceptable color(kelvin temperature), common freshwater pc
bulbs are great and most are in the 6500k range which is good for plants.
