Yard long beans

Has anyone grown these. Planted some in modules then planted them out in the tunnel. They are rowing very slowly and not looking as well as I think they should. The next lot, destined for the bean frame out doors are rubbish and not growing at all and some have died off. All the other beans are looking fine.

 Has anyone got any tips please.

No tips sorry. I tried to grow them years ago- and Red Noodle Beans, not a success so haven't tried again.

Just an update. Well I did get some in the tunnel. They seemed to do best planted directly in the ground. Tried them outside and they came to nothing. They need heat and high humidity. Not sure if I will try them again. We have yet to try them but my Asian friends loved them.

Real seeds are selling a dwarf Yard long bean! I was tempted to buy some because they're "silly" but they're out of stock.
