Well if those are autos. Mainlining isn't really said to work well with them due to the limited veg time. So it's not recommended and said that it usually causes reduced yield for autos. I've read some other mainline grows with autos that also said the same thing as well as one grow myself I did mainline on. Mine was 4 Cola though and I admit I did stunt its growth a bit. I did 4 Colas instead of 6 and only pulled about 15 grams dry off it. But I'm still a fan of the method auto or not. But I'm not expecting it to yield like a mainline photo plant would. I'm going to be trying it next grow again myself now that I've gotten better.
