No , the roots seems to air prune themselves . I have never trimmed them and have never had any root rot at all.
what do you mean by air prune? is that like the root will dry out and the part outside of the block with die off? i germinated some bag seed and they all poped, i have them in rockwool plugs in a dome. they have only been in the plugs for about three days and roots are starting to come out of the bottoms of some. i was wondering
1. do i need to trim the roots at all? i'm guessin i don't judging from your post.
2. how big should i let them get before i put them in to the 6 inch blocks? i was thinking i would wait about a week but wondering if i should make the move now.
3.when would you start using nutrients when starting from seed?
sucks you broke a mainstem but like you said you have some new smoke for xmas, you should wait til xmas day kinda like a present to yourself. and as always thanks in advance, my grow room has come a long way thanks in most part to this thread.
