Q & A

Questions and Answers (1)

i see the el2 can run 2 rooms on 12/12 but can it 2 different light cycles from this unit in seperate rooms or do i have to buy 2 units to achieve this thanks in advance :)
You would need to use 2 separate units to run different light cycles, but 2 12/12 cycles can be run from 1 EL2 Controller.
