No summary yet. It gets written once a few grow reports are in.

Summarized from public grow logs, paraphrased. Sources:

Member reports come first, then public grow-log threads, then catalog suggestions. Each line says which.

A starting point gathered from growers' notes, not a measurement.

No member reports on Costa Rican yet. Yours would be the first, and the numbers above start from it.

Three fields is enough: setup, days to pins, and how it went.

No substrate, grain or agar recipes tied to Costa Rican yet. See all grow recipes.

Tips, corrections and “same thing happened to me” for Costa Rican as a whole.
