==== LED Drivers ====
LED drivers can be categorised into constant voltage and constant current, both with dimmable options. If your panel has a recommended voltage, it's best to select a constant voltage driver. Dimmable drivers are more expensive but worth it because your plant requires more light at the flowering stage than at the seedling stage, so you may wish to use less power initially to conserve power. Meanwell drivers are the industry standard for efficiency and lifespan.
== Light schedules ==▼
Common light schedules include 24/0 (24 hours of light a day), 20/4 (20 hours light, 4 hours darkness), 18/6 (18 hours light, 6 hours darkness) and 12/12 (12 hours of light, 12 hours of darkness).▼
Auto flowers can be grown with lights on 24 hours a day (24/0), but constant light can leave the plant with no time to recover from deficiencies, or stress in general.▼
It is a good idea to match the light schedule with the cultivar's circadian rhythm; I recommend 20/4 or 22/2.▼
