I started all my chinenses and wild varieties in early January and I need help figuring out why I'm having really bad luck with many of them. There doesn't seem to be any pattern connecting the varieties that refuse to sprout.
Some varieties (cumari pollux, mustard fatalii, BOC, Peru Bitdumi) seemed to sprout pretty quickly. Maybe not every seed popped, but the ones that did look healthier and more robust than any pepper I've grown in years past.
A few weeks ago, I heavily replanted all varieties that didn't sprout (about a half dozen seeds in each pot). Of these, some (chocolate habanero, 7 pot burgundy, 7 pot bubblegum) germinated like I'd expect - almost 100% germ. This is where things get weird.
Some varieties just refuse to sprout. And it's not the varieties that are traditionally difficult to germinate, either. I understand that my wild varieties and some of my pubes may take a while to sprout, that's fine. But what's up with 0% germ rates (for almost 10 seeds!) for varieties like Bonda Ma Jacques, Datil, 7 pot Madballz caramel among others?
(Start here if you hate reading long posts…)
The only hypothesis I have (spitballin' here…) is that this is the first year I have used a heating mat for germinating. I keep it on a thermostat set to 83F. I also have eight 4' T8s over them set to 18/6. My (possibly unfounded and hair brained) thought is that when the lights are on, the soil (4.5" pots under humidomes) warms up, causing the heat mat to shut off. Then, when the lights shut off, the top layer of soil cools until the heat mat has time to warm the soil (from underneath).
Is it plausible that this is causing a temperature swing in the top layer of soil (where the seeds are)? Is it possible that temperature inconsistencies inhibit seed germination? If so, why aren't all varieties affected? Who shot JFK? Do I need to do something different, or just shut up and wait?
Questions? Ideas? Let's hear 'em!
Thank you in advance!
