Just interested in how people are using the dimming functions (if they are) on their COBs.

There are a lot of HOW to dim threads... but this deals with WHY and WHEN to dim.

And do you want control to dim outside so you can dim before you even enter the room/tent?
 
I rarely dim. I designed the light to operate at a specific range for establishing rhythm in growing. If the outside environment gets too hot than I dim only then. Peace
 
My plants are too tall.. so I have my light dimmed to keep from bleaching..
My next grow I plan to start seeds under dimmed lights then increase power slowly as the plant grows..
 
  • To give the plants more light at the times of the day they can use it and less when they can't.

Check out a VPD chart and you will see the plants struggle at the start and end of the "day". While in the middle of the "day" they could use more light. Or at least that's my thoughts.

VPD is vapour pressure deficit for reference. So humidity, air pressure, temperature.

With the proper light controller, GrowGreen for example, you can program an hour of morning post-sunrise and an hour of pre-sunset, as well. Strong daylight for the rest of the day, including post-sunset far reds night lights. peace
