Watch it closely to make sure that it does not hermy. Bag seed from dank is always always a result of selfing and the hermy gene is now a dominant gene. You can lose up to about 75% of bud weight in seeds if it self pollinates.
I wouldn't really expect you to be seeing nanners yet. But you will have to check it regularly the entire life of the plant. Nanners can show up anytime--the reason that I never ever grow bagseed. In addition, they can hide deep inside buds and/or be quite hidden. It is simply too easy for a plant to hermy (and it can happen at any time) and you can lose up to 75% of bud weight to seeds. This is very heartbreaking after you have poured 4 months of time, effort, money, and love into your plants to end up with useless seeds and a bunch of sub-par bud.
Are you going to take any clones? Even if you do not plan on continuing to grow past the summer, it might be a skill you want to try and hone. And I am sure that there will some little branches near the ground that you want to trim.
Kindbud, you have probably been lucky. I quit using bagseed sometime back around 2006 or so when I had a bagseed hermy and ruin an entire crop. When it takes 4-5 months to do something, I am not going to scrimp on good basics from the get-go. To me it is kind of like not just going out and digging up dirt out of your yard and throwing a seed in it. Quality genetics cost very little when you look at the big picture. A seed that cost $5-15 dollars will produce ounces of bud.
