Green beans

I have some Ferrari Dwarf Bean seedlings on my kitchen windowsill at present.
I'll plant some out in the garden but wondering if I could keep one or two indoors? My garden is really bad for snails and they usually get my beans before I do!

If I pinch the top off, will it bush out or just stop growing, therefore not produce beans?

Thanks

 

Personally I don't think that they will do very well indoors.
They will be a bit leggy and any flowers will probably not get pollinated.

 

Ahh good point re pollination!
Thank you.
I'll put them outdoors.
