Why We Need UV?
UV is very improtant for increasing the content of THC.
Why we need switches to control UV?
Only when we use UV at a certain time can help to increase the THC content, which means we need a switch to control UV. If no switch, from the beginning to the end UV is always on, this will be a negative effect to your plants.
IR is helpful for plant flowring.
