plant making seeds

I planned a grow that was just for seed production. Purchased regular landrace seeds from very reputable source. (The exact strain is unknown.) Everything went as planned. I managed to sprout a female and make two clones who would serve as the seed-mamas. I recognized the male early by his structure, but decided to test it. Put it on a 12/12 cycle for a couple days. The tell-tale crab claws at the nodes were enough. I put him back into 24 to keep growing until “everyone” was ready. He made several flowers and pollinated all over himself a few times. Then, one day I noticed some odd growth at the canopy and what looked like pistils! I used a paintbrush and pollinated the pistils. The bugger has about 15 fat seeds growing in between his male flowers now. I have proceeded with my seed production and all is going as planned with the females.

Q: Am I wasting time and resources on a project that’s going to give me hermie seeds?

Q: Could the female parts have emerged because I stressed him with the 12/12 light trick?

Any experience or knowledge about what to expect would be greatly appreciated.

Why would you buy unknown seeds from a a “reputable breeder”?

Hermie seeds are not a good way to start. If you’re after the potential for stable and better genetics then toss it and start over and hunt for a stable male.
A potential lead for you:
Check out Heart & Soil. Brett is an awesome breeder who works with stable landraces. Afghan and Peruvian to name some. Good luck on your breeding project.

For landrace and heirlooms i tend to stick with rsc/kwik seeds for some other rarer lines and stuff seedheaven in denmark sells seeds for the likes of baldman and dergcorracollective they been pretty spot on ime if was me and i was breeding for seeds id discard anything that dont show sexual stability saves alot of work in the future
