I recently added a second grow tent. There is a single timer (Hydrofarm mechanical) controlling both 12 hour cycles. The cycles alternate. So I am trying to provide each tent with exactly 12 hours, but I'm thinking the increments on the timer are maybe not so accurate and one tent may get 12h15min while the other gets 11h45min. Is the extra 15 minutes over 12 hours going to freak my plants out? I would appreciate answers that are not speculation. Thanks
