While the coverage a grow light offers is an important thing to look at, it is of no use if the power output is very low. This is because you’ll have to use more grow lights to give your plants sufficient coverage, which is why we always recommend getting a grow light that balances power output and coverage – like the HIGROW 1500W Full Spectrum Grow Light. It produces 300 watts, which is enough for 12 large plants, and can be used from the first stage of plant growth to the last. It also has the lowest price per watt and is more cost-effective than all the other lights listed here.
