The flip-side of the nordic outdoor strains is that they're notoriously hard to keep in veg because of their semi-af characteristics.
Let's discuss experiences here - and even better show pics.
Let's also avoid having lengthy theoretical discussions without any practical knowledge behind it - keep it real.
Here is my example - Freja mother that has been kept in veg since last year. She has tried flowering on me twice and both times all it took to reveg her was a little trim, a root-trim and a repot.
I'll clone her very soon and report back with the results.
I'm excited to see when she will finish outside - and also how finish times are affected by planting times - I will be putting out clones from May through July - possible even put a few out in early August.
Later this year I will update this thread with my experiences with other - perhaps even earlier - strains.
As long as these plants are not getting rootbound and getting enough hours of light they will stay in veg. Even indoor strains will start flowering if rootbound and mistreated but nordic outdoor strains really need to be watched.
A solution is to keep potting up - but of course that presents a practical problem when you start using 10 or 20 liter buckets... Trimming roots and branches a'la bonsai mothers works here, but long term I think making new clones from time to time is the way to go.
