Complete chilli novice

If you’ve already got cayenne seeds. Then go for it. If you’re a real wimp with heat then maybe a jalapeño.
If you come over all flush if you look at the pepper grinder   . Then try a Trinidad perfume ( no heat, not quite so easy to grow, but still not rockets science   ). If you don’t eat much chilli you will definitely only need 1 plant. 
Welcome to the slippery slope of chilli addiction 

Not a complete wimp, supermarket medium curry is fine and I love black pepper in copious amounts and put dried chilli flakes in my own tomato dollop,  so  I will go with the cayenne.  Thanks SC.  Not a chance of addiction though,  I'm with Veggie all the way with aubergines.  I figure with more potential room I can branch out from the normal cucs and toms.   I expect I will end up with 2 gh stuffed to the brim looking like the Amazon jungle and a stern talking to from OH  (which won't make any difference whatsoever)  Thanks for the heads up both of you.
