Some skinny about cannabis drought applications as I see things;
The application of late bloom drought improves cannabinoid yields in both foliar and floral materials.
The early application of drought is counter productive to florescence production. (smaller flowers)
The repetitive applications of drought stress are counter productive.
The indication of leaf wilt (LWA) is the measured angle between the petiole and the branch.
The turgid state is measured LWA when the cultivar is fully fertigated and healthy. This is your zero mark for LWA readings.
Attaining a measured LWA of 50 degrees wilt indicates full recognition of drought by the cultivars GRN satisfying our target stress. The GRN will have fully altered the homeostasis of hormones thereby re-directing the needed proteins in the synthesis of essential oils. The plant will use the essential oils to protect reproductive assets (seeds) from moisture loss.
Attaining measured LWA of less than 50 degrees during drought application presents a linear drop in additional oil production. (less time/intensity in stress = less extra juice)
Substrate composition will change mean drying times but does not impair LWA accuracy. Quicker drying mediums tend to produce the more drastic improvements in cannabinoid yields. LOS and other slower drying substrates can be utilized reducing targeted stress goals.
The process can be tweaked for any medium, but not all strains. This is all genetically controlled by the plants GRN.
Any ? don't hesitate my friends.
So, in an English walnutshell, "late bloom drought" = stopping watering two weeks before harvest can, in some strains, enhance cannabiniod production. This isn't something you want to do multiple times over the life of the plant, just once at the end of the flowering. This does not work for all strains.
Maritimer, thanks for your thoughts. Is there any way to know which strains perform well here?
