Does any devices exist to run 2 bulbs alternatively (like two 12 hrs cycles, one On, the other Off) out of one ballast ?

It is possible to rig two timers in parallel with one ballast. Then you can program varying intensity to simulate natural day light with weaker mornings, intense mid-days, and ramping down evenings.

18/6 leads to high temps in small tent; change light schedule or stick it out?Girls are at 18/6 and 3-4 hours before lights out the tent gets up to 90 degrees and humidity can’t compete. Should I wait it out or try 16/8 moving towards 12/12 close to flowering (autoflower). Will lowering light exposure affect yield more than high temps would at 18/6

Wrong light schedule Screwed up light timing. Thought I was on an 18/6 schedule in my tent but apparently it was 12/12 from weeks 3-7. It’s close to needing to be switched over to flowering size wise. I switched over properly to 18/6 two days ago and plan to keep it there for an extra week. Yes?
