Hi everyone, my first post here and my first grow ever! All going well.

So I'm a day or two away from harvesting a photo-period plant in my grow room. It's on a 12/12 cycle. I have 3 more photo-periods ready to be put inside the grow tent, I've been waiting on my first plant to finish to put them in, to due to limited grow space/light cycle.

a couple weeks ago, I put a few auto flowers in the grow room, without really planning for them much 😅. My question is will switching the autos from 12/12 to 18/6(Veg hours), cause to much stress on them? Or would it be worth mainting the light cycle they're accustomed to.

I'd imagine they will adjust, autos don't rely on light schedule to determine when they start flowering and will flower in 18/6.


Autos dont care about light schedules. The more light hours you provide the faster they will grow. However, running 24 hrs no dark period, is a waste of electricity, and costly in the long run. The extra growth vs the cost factor of electricity, becomes very negative running more than 18/6 light schedules. 16/8 or 18/6 are the most energy efficient light schedules if cost per gram of bud produced is a factor for your grow. I hope this helps you in your grow.
