things are looking good Herk. I haven't been on to much since roll it up took a break as I haven't been able to upload pics and it is annoying me. I took my plant that was furthest along down last night. she looks good. I took all the tops and big buds and left the smaller stuff on for a few more days, let it get light.
my others should be a week to maybe 3-4 for the big sativa plants.
I have heard from many they think soil smells better. don't wish to argue it since I only know dirt growing. so your observation is likely correct. even some ferts will change the smells quite a bit.
