Looking very healthy man! =D keep it up
As far as height goes, it seems you got plenty of room. I guess it all comes down to when your ready. Good luck.
I'm following this man. It looks like you have a lot of space
If you are flowering this week, the fresh cut tops might not recover soon enough to get max effect. You would have more budding sites I would imagine.
I'm with you on the led option, I want to learn more about DIY led setup. Some people on here have been doin some awesome stuff with em. Still lookin real healthy by the way.
Can I put multiple plants under a scrog? Maybe 3
Yes as long as you use a screen that's large enough for the three plants, it shouldn't be a problem.
