I am looking for the best (while also being affordable) plant lights to use in my office and areas of my house that don’t get a lot of sun. How many lights will cover how many plants!? Is it one light per one plant?! Is there a huge difference to white light vs. purple light?! What about LED vs. others?! Is there a kind of light that is better than others?! HELP! *Amazon is not helpful as there are WAY too many options!
