Great idea for a post. I wanna say, congrats on the prospect of getting more land--i am a satisfied small-scale repeat customer of yours and i love your business practices, my only possible complaint is you could stand to offer more variety and more land could help you do exactly that!
I also want to comment on your observation about PuckerButt's Reaper. It's a weird paradox or some shit that one of the most commercially successful varieties is so flawed. I hope you'll dump the Reapers, grow Primos instead. Or, better yet, maybe work on re-setting and improving Red Brainstrains or even maybe 7SR? A lot of heat potential there, and thru 2019, Brainstrain is so the most powerful chile I've eaten to date... And getting quality Brains send to be getting harder as time goes on.
Here are my somewhat pointless responses to your excellent questions...
1. What were the best peppers you grew this year? why?
All of my best peppers in 2019 were pretty much the same best peppers i grew in 2018 & 2017. None of the "new-to-me" varieties really blew my mind, although many of them impressed me, for sure. My old favorites remain Red Brainstrains, TFM Bonnets, Zapotec Jalapeños (to be fair, i didn't grow these in 2017), Naga Morich, JPGS. Standout new favorites include Aji Jobito and Big Black Mama, but neither of those send me like my top favorites.
I will say that this was the first year that my Primos kicked ass. I got many pods, all very hot, very consistent, very deliciously hot. My only gripe, which i also had last year, is that the pods were pretty tiny. It's tough to abide by Lilliputian Primos growing next to big Jonahs, Barrackpores, and Brainstrains....
2. What challenges did you have this year? did you solve them? how?
My biggest challenges, tbh, were unintentional crosses (from seeds i knew to be OP, so I'm not mad, but i will likely grow more from iso stock in 2020), finding homes for my ridiculous surplus of culls (which i mostly solved, i guess... Gave most away but i know probably 2/3 or more of those died. The rest i grew in fabric pots in media i improvised last-minute. Got mediocre results with those, at best), and StankBugs in my Jalapeño patch and SuperHot patch...i didn't quite solve that problem, but i did manage to reduce damage by quite a bit, using old fashioned ninjitsu techniques plus some FGDE.
3. What changes will you make for next year?
Slightly fewer plants, far fewer varieties... Trying to mix up hear levels and generally "types" a little better, and I'm even working out percentages of my grow in certain heat ranges, colors, species, etc. . . This year and last, i planned out my grow on googledocs using tables to represent beds, with the grid system providing coordinates showing which plants were where. Now, I've added the % of Supers, Hots, Mediums, and Milds, colors, etc.. and I'm also not carefully planning my number of seeds started for each variety, to suit my plan and my available indoor space, but also for having the number of culls, and even how many seeds I'm starting for plants i know i get good germ rates for, vs ones that i anticipate poor germination rates..
TL;DR: lots of pedestrian nerd-ass planning, with semi-dubious math and my usual pessimism in-place to muck up my results...
Again, thanks for the awesome thread idea, Juanitos. Sorry if my response is too long-winded.
