@AliGal first time I grew them in a kit, ended up giving plants away as they all grew lol. Now I just buy the blocks of dehydrated soil/compost, pots and seeds. The trick I think is having a sunny windowsill and one of those little propogator (I think that's what they're called) to keep the heat in. Last time I grew from seed I just used a plastic tub over the pot. Once they're growing I use chilli focus plant food following the instructions on the tub, and water them when the soil feels dry. I think historically I was guilty of overwatering things. I've even killed cacti. I've grown lots of different types, but at the moment I've stuck to one plant as it's only me that uses them here now. It's a cayenne plant I grew from seed last year it was a little project at the start of lockdown with my son, we also grew jalapenos and apache, but I gave those away. The cayenne works for me, I throw them in soup as well as chilli and curry dishes. I freeze the fruit as well, so this one plant has kept me going all winter, and it's fruiting well again now. I cut it back in winter but it never really stopped fruiting only slowed down.
