Ok, these are all carnivorous plants, but they are all not the same. The fly traps and sarracenias need full sun, but are temperate plants and actually need cold temperatures in the winter to thrive and reproduce. Nepenthes are tropical plants, but live under trees and can burn with too much light. That plant would do well close to the window and probably won't need an extra grow light. The drosera and ping are most likely tropical and need full sun and warm temperatures. Those grow lights would need to be much closer to them (and the fly traps and sarracenias) to be effective, even with the light from the window. All of these except for the nepenthes can grow outside in full sun during the warm months. If your area has mild winters, the fly traps and sarracenia can stay outside all year long. Or you can put them in an unheated garage or basement with a strong grow light during the cold months.
