Mexican seed breeding

At my friend's house he has seeds that he got in Mexico from a giant operation. He said he just wanted to buy some green while on vacation down south, and the guy he met took him to where they grow and showed him the plants. No idea how big the space was but he said huge. They gave him a baggie of seed to grow, and he found some seed in the bud which he said he didn't keep. Hoping he didn't bring home schwaggy Hermie bag seed and instead find something worth keeping. Extremely variable and mixed genetics means this will be a fun little project. He had 11 seeds and wanted more, so every time I go over to his place and checking up on the plants and keeping a log. We will be selectively breeding these 11 plants, sativa to sativa, Indica to indica, that kind of thing. The goal is to just produce more seed, but not so randomly that we have no idea what it is; it'll be nice to know whether it's a sativa or indica dominant growth style. There will be no bud produced from this grow diary, just pollen and seed. Seeds were labelled with the ID MEXxx where the last two digits are number based on how fast they germinated, 01 germinated the fastest and had the longest taproot whereas 11 took an extra day. Stick around maybe I'll put some observations keep you all informed.
