I'm going to be conducting some light experiments soon. I've found plants grow best at 6500k color temperature but I'm going to do some experimentation with some 8000k car fog light bulbs and have these shining on the pothos.
This summer hasn't been very sunny, so far its been many weeks of dull overcast days . I'm hoping the weather picks up soon so I can have some sunshine coming through the windows.
I think car head lights could make good grow lights for house plants.
