Make yourself a cup of tea and with the used t-bag make another and leave the t-bag soaking until you have drunk the cuppa you've just made and discard the bag.
Leave the weak tea until its cooled down before you use the tea solution you have just made.
Soak your chilli seeds in the tea solution for 24hrs.
Place 2 pieces of kitchen roll that have been folded into a quarter in a plastic bag/sandwich bag/freezer bag basically something you can Seal airtight and wet the kitchen roll so its as wet as a wrung-out sponge.
Place the chilli seeds in the plastic bag on the wet kitchen roll and inflate and then seal.
Place in an airing cupboard or propagator or on top of a warm not hot radiator.
Check the seeds every two days and dampen the paper if it starts to dry out.
Once the seeds have sprouted you can transfer into 75mm pots.
The reason why you use the tea is because chilli seeds have a hard outer coating and the tanin in the tea helps to scarify the seed coating and make it germinate easier.
The hot varieties of chilli can be tricky to germinate at times and will benefit with a germination temperature of between 80°F and 89°F, also do not leave your chilli plant on a window sill over night as temperatures can drop and it will not do your plant any good.
