My seeds came today! Any tips for those who have grown these varieties before?

The seeds are from whitehotpeppers.com. Top two were freebies 🤙🏻

I'm so excited. Especially for the aji charapita and the JPGS. Any tips from folks who have grown these before? I've heard the aji charapitas can be a pain to get past the seedling stage for some.

I have a photo of my set up in the text photo (not including the fan I have which is just off screen) all tomatoes and sweet peppers at the moment. I've been germinating everything in paper towels folded in plastic on that heat mat you see on the bottom shelf. It's been working great for my tomatoes and sweet peppers so that's what I'm going for with these guys too. This is my first time growing real hot peppers though
