HELP! NEW CACTUS SEEDS! So I got some barrel cactus seeds (exact type listed below) and planted them and some sources say to cover with plastic wrap and a ziploc bag while plants says to make sure there is plenty of airflow? I get the humidity dome thing but I’m also worried there isn’t enough air and it could mold? Anyone have any tips on a happy-medium or is it okay just covered with the plastic and bag?
i personally like to use the paper towel method when starting from seed. 30 minute soak in 3% hydrogen peroxide to kill mold or fungus, then a 24h soak in water to boost chances of germination, and you put the seeds in wet paper towel in a plastic bag and forget it on your counter for two weeks 🤷♂️ easiest and least stressful way i've ever done it.

I have had luck with the dome method. Moist medium with dome on top, never had mold issue. Especially if it’s just moist dirt, not soaking wet. Where I have had mold issues and rotting with the paper towel method although I never did the peroxide method as stated above.
