Question about breeding timeframe for shrimp

[FishBeast]

I am about to buy 20 shrimp for breeding stock and out of curiosity I am wondering generally how long it will take from when the babies hatch to when they will be about 10mm in length?

A female bears eggs "under the tail" for 3-4 weeks. Baby shrimps grow up for 3-4 months. Its about cherry shrimps.
