 HID Lamps
 You can also put your money on HID lamps to help grow plants
indoor. Growers can choose from different types of HID lamps,
including metal halide bulbs and high-pressure sodium bulbs. You
may want to put your money on these lamps when you are interested
in lighting large areas. They are quite suitable for hydroponic
gardens because of their high light output. They use a bulb along
with an electronic or mechanical ballast. In terms of efficiency, they
are much better than incandescent lamps. The only issue is that they
come with a limited lifetime and are likely to fail at any time.
 LED Grow Lights
 If you are looking for the most reliable option, you can certainly put
your money on LED lights. They are available in different sizes and
produce different spectrum of light to ensure that your plants can use
the light for proper growth. LED growl lights come with several years
of guarantee and are available at almost all stores selling hydroponic
supplies.
