U3B22 will have this rig for stretching the balloons with dry air. It appears that moisture compromises the balloon membrane so I modified an old propane regulator to maintain constant pressure and used a modded preserving jar filled with crystal cat litter (silica gel) to dry the air before it inflates the balloon for stretching... After stretching the air is vacuumed out and the balloon is put in a airtight bag with more desiccant to make sure it is as dry as possible before filling with hydrogen.
