Aren't long enough for what? As soon as there's a tip of a rootlet visible, a seed should be in the ground (/perlite/soil in a cup/etc.). It's not doing a thing other than using up that tiny little finite amount of stored energy that's packed inside the seed case with the plant embryo.
For that matter, the seed should be planted before the rootlet appears. But I don't usually do that, either. So I felt hypocritical even typing that sentence :icon_roll.
If you see a little white tip, put the seed where the little embryo inside it can begin growing.
Not for an auto man . Auto go in final pot this case 5gal pot . I like to get a good jump start on root depth so when I plant the tap root it's down a good inch or so already so it makes it easier for her to hit the bottom
Of that pot I Want that root going deep bud.. then it can reach sides ways everywhere the better the root and vegetation stage the more better the fruits no? Again this is me and how I try to make sense of growing cannabis. Hmm we have bumped heads but let's see where we can meet at least? Lol
