All our chillies get the same start,each small batch of chillies goes in the airing cupboard tween some wet tissue paper and popped into a foil food tray with cling film over it,but depending on the variety some will sprout afore others,I seem to recall our bonnets sprouted about the same time as our cayennes.....any road once sprouted I stick them in a heated prop on a constant temp to help em grow on...I think there worst enemy is us as we like to interfere to often and the temp fluctuates and the sprouting process is stunted.
Good post this as im always looking to improve chilli growth methods.
