I would think dumping boiling water in to the root mass would do more damage to the biome in that medium over any “plant benefit “.
This seems to be an old stoner myth just as Ice water.
just grow / cut / harvest / smoke
Plants do not care what week or day its on.
They will finish when they finish. And yes , some issues can stall or drag a grow.
Harvest times are just “ guides “ only.
Probably would work - even as a preventative technique. Wrap container like a wine bottle / wire tie around stalk ( open to water ).
Smokin Planet Red right now so … I am thinking from a cloud - sorry :bigjoint:
Repot ( double size )
What is that medium ?
If its “ soil “ - mix up a new container with added perlite ( don’t see any in your current pot ).
is this an auto or photo ?
( strain ) ?
