I’m thinking maybe it would stress the plant out. When we change light schedules there is a shift in plant hormone that forces the plant to flower. I don’t know if the plants could decide/separate them and sent them to certain parts of a plant.
I would worry about light leak, also when you flower sometimes internal switches get turned on that never get turned off again and this can affect strength and yield. Over time I would imagine it likely the plant would suffer reduced quality.
I guess I am in the ‘would stress the plant too much’ camp
Also, it sounds a ballache. You can get a mother and a couple of clones in a very small space using hardly any power.
An interesting experiment but not of much practical use IMO.
To answer the question though, I have not seen nor heard of this being done before.
i don’t think i understand what you’re suggesting …, do you mean re-veg half the plant while the other half is flowering?? because i dont think that will work
