I bought some T. bridgesii and T. peruvians seeds, and to my delight I had my first sprouts (on my birthday, no less) :d . A few days later, and there's 21 of the little guys.
I've never grown anything from seed, and never grown cactus, so any advice is welcome. Right now there in a closet with a window and have just had natural light. Should I switch to a grow light, and when if they're too young now?
Also, does the middle one in the first pic look sunburned?
Thank you!

I'm only one year into my cactus journey and I think growing from seed is a fulfilling path to trod. May you grow together toward the light.
