I suspect you're right. I don't remember where we got the seeds. I do remember that they were sold as autos, but obviously they're not autos. They also came in little zip-lock plastic bags, unlike seeds we've bought since that come in foil-like pouches. It was our first indoor grow, so we didn't know what we were doing. We've bought our seeds from Seed Supreme lately and are happy with them.
I didn't expect these to take so long. I only grew them out of curiosity. We didn't harvest our first Black Jack grow due to spider mites. So, we wanted to see what these plants were like. We also wanted to practice growing. It looks like we'll get a crop this time. We don't have any more of these seeds.
I'm thinking now that the initial problem was the soil. The Amnesia Haze I started after these was also slow, even though they were in different soil. It was probably another poor choice on my part. One of the next learning tasks on my agenda is to explore the qualities of good starting soil. I've been thinking about starting a thread on the subject. Then again, I could hardly do worse than I've been doing.
