Out of sheer curiosity, I'm going to pot up a couple seedlings (Bhut, Red Caribbean) with 50% as a control using same-sized 'grow bags' made of a needle-punched nonwoven polypropylene to see if the increased availability of air on the sides helps things out.
Really neat project, OP! I'll be following this to see what happens.
