I like to grow manifolds, I let mine get close to 20 inches before I switch to 12s and I average a quarter pound per plant.

Your plants look beautiful and you’ve got em nicely trained so I think if you’re patient with them and have enough quality light it looks like you have the space to get a half pound out of each of them. I always cram as many plants in my space as possible so I grow small plants. On my next round I want to try less plants but let em get much bigger. I started growing them smaller because of the lights I was using they didn’t have much penitration, with the better lights I now have I’m going to try bigger plants again 
Yeah man good luck. I have a 3 x 4 room for my flowering 12/12 all the time. And an 18 hour grow room where I can grow a couple of large plants and throw some autos n there to hold me over till the photo period large plants r ready for harvest. What’s your light set up?
I ran 2 off brand 600w blurple lights 113w draw each for a long time and I think I got as much as I could from them and averaged just over a quarter pound per round. I added a spider farmer sf2000 to the 2 blurple and ran two grows first got 526grams second 587g. Now I’ve added a second sf2000 and moved from my 2x6 closet to a 4x4 tent. shooting for 2 pounds I’m about 2 weeks from the switch to 12s for flower. I’ve had some hiccups during this grow but they’re still alive
What do you have for light
I had all my plants together under one 400 w hps and 600 w mp or mh for the flowering. I think I jumped to gun. Now I have the the two large ones and 2 autos under 600w hps. Not sure it’s enough. And one gdp in flower under 400w hps.
I don’t know to much about lights except for a little bit on LEDs. I do know by reading that the old way of judging lights by watts is from the bulb lights so we can easily figure it out. You take the square footage and you want a minimum of 30 but optional is 50-60 watts per square foot. 3x4=12 12x50=600 … now again I don’t know those lights but by the math 600w is your target. I don’t know what the footprint of the lights looks like but sounds like you have them covered nicely with your 600 hps and the single under the 400

I flip my manifold plants once I have 8 main colas and each one is six inches long.
just flipped three days ago
No trim before flowering stage? I’ve got 10 plus colas on both and are over 8 inches. What’s your yield per plant? What nutrients do you use. What’s your light source
I use general hydroponics flora trio. My best plant gave me about 14 oz. But average 7 or 8 oz. That plant is under a 315 lec . I defoliate 3 weeks after flip
How’s the room looking now @Ky
A new set up. More of an open area set up.
