My first experience with the Bhut's have been grown under lights, plants grew about 4 feet tall, had about 20 pods max. Only ever saw 2 flowers growing out of the one spot.
Since putting these plants outside, and even in mild temperatures (I'm talking 15C max during the day, 5C during the night), I'm now seeing a crapload more flowers forming. Compare that to my Red Savinas that really look to be struggling right now and will probably shut up shop until the temperature starts climbing.
Im starting to think the Bhut's are a little more hardy than expected.
