It seems that the clear winner is the LED grow light compared to the fluorescent grow light. The thing is, LED grow lights have come so far that they are far and away the better choice, but only in certain circumstances. If you’re just getting started with indoor gardening, it’s a good idea to start off with LED grow lights. They are pricey, at first, but they pay off in the long run. Plus, if you just have a handful of plants to start with, you won’t need a giant setup. For the coolest-running, most efficient grow light, there’s nothing better than LED right now. However, if you have a large indoor garden, you’re going to have to buy a lot of lights to get sufficient coverage. In this case, the fluorescent grow light may be a better choice. And if you already have a fluorescent setup, there’s no need for you to replace your whole system. The bottom line is that LED grow lights are a better choice for indoor gardening, thanks to the lifespan of the bulbs, the next-to-zero heat they produce, and the savings you’ll see on your electric bill.
