I treated them like a bog standard houseplant, didn't let the media dry out to much, feed regular etc.
All I know (for me) is they grow like wildfire and quickly outgrew the windowsill I had them on (wish I had a green house). I would also add they can be a bit of a pest attractor, so watch out for that.
From seedling to a litre ice-cream tub full of Chillis from one plant in one season. initial outlay 50p per plant.
Growing regimes may vary between types, but other than that they seemed relatively easy to me.
Will I grow them again?.... When I have a green house, Yes
Cleaning, chopping and putting them in a bottle and filling said bottle with oil also provides another quick and easy option for future use.
