Right now, the sunlight in my south window is great (~6 hours a day) despite living next to a mountain to the east that cuts down on morning light. Come summer, I expect hours of direct sunlight to go down significantly as the sun is directly overhead come noon time in addition to the mountain blocking some morning sun. I don't know how much of an issue this will be so I decided to look into supplemental LED light sources. I bought two of these LED grow lights from Home Depot:

They'll be about 5-6 inches above the Drosera and about 8-10 inches above the Nepenthes. Given that the plants are still in a window that in the summer will at least get tons of indirect sunlight, how long should I keep the lights on each day? I know the general recommendation for growing only off artificial light sources is 14+ hours a day, right? Should I still aim to keep them on this long or would something like 10-12 hours suffice?
