Is it too late to put in a trellis net in my tent?...

woah what an absolute beast , and this for gens reputed to be short and stocky. Next time you can SCROG but main thing is to watch that lamp to plant distance bro ! she's got legs on her though, i'll give you that ! I know this isn't the answer you're looking for but there's nothing you can do by now. One thing i will say about trellis nets is that i've seen plants basically not give a hoot and push forth like it was nothing, i'm trying to coat some metal chicken wire in some plastic coating , that's what i'll be using to thread my ladies through. I've seen folks get better yields SCROGing one plant than SOGing 6 so yeah looking forward to this, and for your next time, so should you ! Good news is that the GSCs stop growing end of week 8, you're at the end basically, she'll start to buff out and should be ready in 2 weeks ! Sorry for the tough answer, but it's the truth ! hope this helps ! 🚀
