You mean you're getting seeds from the plants but you don't see any male plant parts on the female plants? If you're getting seeds there's definitely some male parts on the plant dropping pollen and pollinating itself or other plants in the same room, that's the only way a female plant can produce seeds. I'm going to say it's growing some male parts inside the flower if you can see them, them producing seeds.
Opp's...yes as I recall there was a few males this round in the GH which I pulled out.But in the indoor there are no males and some plants still give me a few seeds with no males at all.
Cali connection is a good company, I've went through hating them, liking them, hating them, back to liking them lol. The owner of the company has had his quality control issues, but I think he's better now. His OG's are good, and his sour diesels.
In this thread I update pics weekly, it's quite a long thread to go through though, here's another thread of mine that I update weekly and it's not that long. There's a few grows with different styles of growing a single strain. Skip the first few pages because I was in the process of moving and the plants died.
