Back again.
I would use a soil based compost and a wide based pot.
The plant can get LARGE, I had one weighing in at around 40lbs.
If you let it bake in the summer then you can get it flowering in the
winter.
I had a Barber in Cardiff who kept his plant in the shop window which was
South facing. every Xmas it was a mass of flower
