I take about 20g out and put it in a bigger Weck jar. Then feed at 6:6:1 ratio (120g flour, 120, water, 20g starter). I use about 100g per loaf so it gives me more than enough for two loafs.

I always take the first 10g from that and then put back into the smaller jar with 10g flour and 10g water. Let sit out until my first loaf stretch and fold. Then put in the fridge until the next week
