What exactly do you do to get the peppers to maximum hotness? The wiki article says runoff from worm farms or something like that. I know they can range from barely above a habanero to hottest in the world.
Run a search on this forum... There is a ton of good info on this.. Stressing the plant is one way. Also breed of pepper will also determine heat level.
Start reading the AACT Sticky as this is great info on feeding your plants (which once your seeds sprout you will need to do).
