What are you trying to grow???

Not talking ****
But growing carns from seed isn't exactly to best way to go for a NOOB

Get some established Plants / Let them flower & go to seed & go from there

But if you want to start your collection from seed
Dews Sarrs VTFs are pretty easy / not to hard to start from seed
But Neps can be a pain (IMIO) & can take forever
+ Be careful were you get your seeds from / Nep seeds need to be fresh

Good Luck

I'm interested in these plant, do you know where to get them? I also heard that growing from seed can be rewarding, and the roots are more developed
.

I would start with plants first not seeds. Try these vendors:
