I realize I’m a bit late to the game and should have planted seeds in December…. but I’ll remain hopeful and give it a go anyway. Peppers are being started in Jiffy trays (Buy from US / Canada) on heat mats (Buy from US / Canada), under full spectrum lights (though admittedly not an ideal lighting setup in this case, but the best I already had on-hand. Seeds in the “ground” at this point include:
Yellow Brain Strain
Red 7 Pot Brain Strain
Yellow Carolina Reaper
Trinidad 7 Pot Douglah (chocolate)
Moruga Trinidad Scorpion
Of the above group I’ve previously had success with the Thai Dragons, Red Habaneros Moruga Scorpions and Carolina Reapers, but the others are new to me and we’ll just have to see how things go.
I’m convinced that without full spectrum lights I would have no chance of growing super hot peppers quickly enough to get a harvest in the Pacific Northwest. Similarly, I’m convinced that without heat mats I would have not chance of germinating super hot peppers reliably and early enough to get a harvest. If you’ve tried one but not the other, make sure you try them together, and start early .
In addition to the heat mat and lighting setup, I’m planning to add a fan after they’ve germinated to try and strengthen the young plants early. I’ve had a tough time in the past hardening pepper plants for the transition outside. I’m not sure if this is a common issue, a reflection of having started them late and trying to transition when too young, or just a fact of life given Vancouver’s somewhat unpredictable weather.
Most of our super-hots were grown outdoors on the roof (as one might expect given the title of this site), however we did keep two inside in our south-facing solarium. Both Trinidad Moruga Scorpions, the peppers grew well indoors, producing peppers, though not nearly as well as the top outdoor plants. At season’s end we noticed aphids on both plants and so pruned them back to just the major stems, sprayed them down with insecticidal soap (Buy in US or Canada) and tried to start again.
It appears we were successful.
Despite it being December in gray, rainy Vancouver we currently have two healthy Trinidad Moruga Scorpion plants. One with 4 nearly mature peppers colored and waiting to cause pain. Both plants have new flowers forming as well, promising additional harvests through the winter.
We did not use grow lights of any sort, though during the day the room is kept slightly warmer than the rest of the home. I will admit that I do have a grow lamp at the ready should it be needed, however I’ve been able to keep it in storage thus far. Other than that, no special treatment. Plants are watered regularly (with water from a nearby aquarium) and that’s about it. So… give it a try and you could find yourself in peppers through the year with little extra effort.
Fortunately we experienced another hot (for Vancouver) summer this year, which the pepper plants clearly enjoyed. Cold periods in the spring definitely delayed the plants materially, to the point I wasn’t sure if they’d survive. Fortunately both those started from plants, as well as those started indoors from seed managed to recover and produce.
Of all the hot peppers grown this season, the Carolina Reapers were the ones I was most concerned about. They started slowly (very slowly) and took a while to start setting fruit. Fortunately, once they got going they really took off with one of the reaper plants being the second largest across all varieties. Production was good as well, though not in line with plant size.
Observations & Learnings
These peppers seemed less cold tolerant than the other types I grew this year.
My reapers seemed to build heat later than others. For example, I (cautiously) tried a fully formed, but still green pepper and was able to eat it as I would a bell pepper. There was no hint of heat.
Don’t let point 2 fool you, these things are crazy hot. I still don’t understand how someone can just throw an entire, fully ripe Carolina Reaper in their mouth and not completely fall apart.
Carolina reapers require more post-harvest preparation for use than others. The reapers are not only ‘bumpy’ but folded in on themselves consistently. I encountered trapped material in these folds for most of my peppers, which required cleaning. This wasn’t easy and in some cases scratched the pepper itself, so wear gloves (which you should do regardless). I hesitate to mention, but I found small webs in some of these crevices, suggesting that spiders or something similar are taking advantage.
