This Bubba x Sky s1 is Nice!!
but its lagging behind.
I'm not sure to replace it or not.
I don't think it will take advantage of the large pot.
I don't think it has the potential to get to be huge but i think this cross has some fire in her.
The Bubba is a kush that stays short and squat. Its not lagging behind imho. Its just that the leaves are bigger and the nodes are tighter so it just seems that way, cuz its energy is going into growing big leaves and more nodes instead of longer branches.
I think it will still yield heavy. I wouldnt replace it. Add another plant gorilla if you feel you need to make up for the lack of yield.
