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.
