How to get to León or Granada from Managua

What is a more safe and somewhat inexpensive way to get from Managua to León and to Granada?

Chicken bus fro Managua to Leon 38 CS, micro bus 54 CS.

Both secure - 2 hours and 1:30 hours.

Granada should cost a little more.

Both start at terminal UCA.

I understand UCA, but where and when do I get on a bus from Granada to Managua?

I saw a Granada to UAC Managua bus pass across Calle la Libertad at the ruins of a large building I assume is called Hospital Viejo.

It was mostly full.
