so June 10th ... put in the dirt
I’m week 3 in to flower now
the seeds sayyyyyy there 90 day flowering
They'e 8 weeks old. They look about right to me.
I think you're saying the seed bank advertised then as 90-day till harvest(?). Thats' 13 weeks. So, you have 5 weeks go, which looks about right. (Usually seed banks say something like "7 weeks to harvest," which would have confused a new grower about a week or two ago. I think they mean "earliest possible harvest." It's good to see a more realistic estimate of 13 weeks.).
From what I saw on an autoflower forum, most people harvest around 11 weeks. I usually did 12, but 13 once. I think 90-days (13 weeks) is a bit long for an autoflower (and that's surprising to see a seed sold erring in that direction instead of the typical early estimates.).
You're just going to treat harvest like any cannabis plant. When some pistils are brown, and the trichomes are some amount of cloudy or amber (your preference). If you don't have a microscope to look at the trichomes, you probably need to start looking for one now. (Harbor Freight sells a set of loupes cheap. They have a magnifying glass that clips onto ordinary glasses. You can buy a pair of cheap reading glasses at the drug store. Get the strongest magnification. Probably 3x. Clip the Harbor-frieght thing onto those. The Harbor Fright thing has two round lenses that swing down in front of the reading glasses. With both round lenses it's strong. And then the 3x reading glasses triple that. It's not as strong as a microscope. But, just about strong enough to look at trichomes. (16.5x times 3x).
