been following from the beginning, just didn't have anything useful to add.

Weedhound and Treetops are right, you can bury that stem right up to the cotylodons (lol, did i spell that right?), if you hadn't, those with the stems getting thinner would surely die, i've watched it happen. i'm not sure this will save them but they were gonna die otherwise so i hope this works for ya.

anyway, can't wait to see these babies grow, rock on man!
