I noticed that last year, but once the pods are bigger, the calyx appears way smaller. BSH is growing F2 and he has the same calyx. Kinda like the seeds. I've noticed that they're smaller than most Chinense. I'm pretty sure there is no way my seeds crossed because I isolated using glue. Do your baby pods appear to have a bigger calyx?
Well the old west used to put silver dollars in the barrels to make sure they were bacteria free, Fine Silver is great for antibacterial properties like people using colloidal silver solution. I used to put a piece of silver in the bottled water dispenser I had, it has to be fine silver not the mixed crap.
That could work.
I use a 99% silver coil in my PC water cooling reservoir to control algae.
