Absolutely no sulfite or minimal, something minimal like 10?

Primary I always do in the house (avg mid 70s) and temperature peaks in=20
the 90's during primary fermentation. I guess I need the same=20
environment for MLF as well (which means I'll be looking at those tanks=20
for a number of weeks).
