I'm also a non believer when it comes to led although many on here and other sites swear by them, I wouldn't hesitate to guess how much it will stretch, how she will handle being under the net, not all strains are scrog worthy. I attempted a scrog this time round and I didn't like it too much after stretch so I cut it away, now my plant looks like she has just been heavily lst'd, but that's what I mean abouts it being all up to you to decide! Hope you don't feel like I'm jumping down your throat, your doing good apart from that net lol if I was you I would flip them now but then that's me. Good luck in what you choose
