If the timer is amp rated to hold
both then you can. I have dual and four outlet timers I bought when I was wondering the same as you.
would either of you @mwhite9829 @Mr. Grow It know if I can use one timer to control both lights since they’re daisy chained? Or do I need 2 timers per tent?
Looks like your doing awesome, all Id suggest at this point is enjoy it when it's done. Nice job 👍
Nice healthy plants you got there. Good plan to flip in 1.5 weeks from now; that should be enough time to continue to bend the plants down to fill up all the squares in the trellis net. If you need to top 1 more time then you have enough time - specifically that branch in the middle.
What nutrients are you using?
