Choosing the best grow lights is one of the most important first steps for any cannabis cultivator. All cannabis plants will need lights to grow. Lights allow plants to perform photosynthesis and therefore feed themselves and grow. 
But, what are the most common types of grow lights used by cannabis cultivators? Luckily for you, we have broken it down into two parts, as we do every PotCast, to compare the three primary types of grow lights - MH, HP, and LED. 
First up, Kronic compares MH and HPS grow lights. MH lights, otherwise known as Metal Halide lights are pretty common as are High-Pressure Sodium lights, but which one is better? Largely this depends on a number of factors and either may be preferred by different people. Much of this comes down to the price, how much electricity they consume, and their efficiency as well as what they provide for your plants.
Then, in the second half of the PotCast, Kronic looks at HPS in comparison with LEDs or Light Emitting Diodes. LEDs are fast becoming a favorite for many growers; find out why this is and how they compare to HPS lights in this week's PotCast!
