Just toss it in a corner in the tent or somewhere in a covered corner that can stealth it outside and just let nature grow it for you.
I feel you on the bagseed note, but if it's for smoke and not sale I see no issues with using bagseed. Some of the best strains to ever Grace the planet came from bagseed.
With how it's growing I'd give it a chance to shine personally.
In my grow I started a bagseed that fell in a cup of water I was drinking and decided to roll with it. I couldn't be happier with how Tulip turned out. She's a GSC bagseed that is trying her best to compete with my main plant at a rapid pace and she looks way healthier too. She is a heavy feeder and if I went below what I was yelled at for using she would yellow and eat herself. Nothing I could do to her slowed her down. I've snapped her stems, given her very low light, overwatered her, and in general just treated her like she was useless and going to die.
My main plant Zelda for comparison got heavily clawed with the compost I added to fix my soil structure. Tulip got a bit darker, but never clawed up.
Now it's looking like Tulip will take over the tent if I let her and all because I took a chance on a seed I viewed as useless I had wanted to experiment on.
