I have the ac infinity ionboard s44 and controller 69. I use photone too, just when the plants stop stretching I like to get them all around the same height so the canopy is getting even coverage, just forgot to change backView attachment 1656785
What light do u have that the dimmer is so weird? Why I didn’t like the medic grow light cuz without a digital controller which is like $200+ the dimmer only goes 40/60/80/100%! Depending on size of your light tho u can always do a combo of adjusting dimmer and light height! Just use photone to check ppfd output! Only $6 to unlock full spectrum LED!
it'z all good
