In either case, could you kind folks set me straight about the proper use of this gadget?? If there is one??
I've used it for every batch this year.
Works great. Lag times are usually a few hours and fermentation is very vigorous.
I usually do 45 seconds after pitch with a slow flow.
Then another 30 seconds about 3 hours later then a final 30 seconds at pitch + 6 hours.
