Yep,
Salut armistice,
C'est un phénotype spécial qui a atteint ce taux, pas tous loin de là (génétique encore )... Ce phénotype même si tu le cultives de façon merdique, il va pas te sortir une bonne zeub mais le taux de THC il sera stable... par contre comme dit Flask moins de résine etc.
Ce que tu insinue c'est que les facteurs environementaux n'influence pas sur le taux de THC.
Mais tu dis qu'il y auras moins de résine (trichomes), les trichomes étant l'endroit de la plante le plus chargé en THC, si y'a moins de trichomes la concentration en THC de la fleur serat moindre.
Je suis entrain de fouiner dans le bouquin pour trouver le passage mais c'est pas évident il est gros et il parlent de tHC a presque toutes les pages
En attendant j'ai trouvé un petit texte sur le net:

Abstract
Cannabis sativa plants submitted to 10 and 12 hours of natural light showed different content in cannabinoids. An increase of exposure to natural light of only 2 hours a day, at least, doubled the average amoung of THC, but decreased that of cannabichromene.
To study the influence of light on flowering of Cannabis sativa (Valio and Valle, 1973), seedlings and rooted cuttings obtained from hemp seeds cultivated in plastic pots were submitted to different photoperiodic treatments. Lots of 10 plants were used per treatment and all the pots were moistened every day with tap water and every 15 days they were given a complete Hoagland's nutrient solution. Temperature ranged from 17 to 34 °C.
During the 65 days period all plants on the 8-, 10- and 12-hour photoperiods flowered. Plants on 14- and 16-hour periods did not produce visible flowers. The flowering tops and leaves from plants with 10 (A) or 12 hours' (B) exposure to natural light in the glasshouse were collected, dried at room temperature, separated from seeds and fibres and powdered. Powders (A) and (B) were extracted with chloroform (Fairbairn and Liebmann, 1973) and their content of cannabinoids determined through gas chromatography by employing basically the procedure of Lerner and Katsiaficas (1969). Presence of tetrahydrocannabinol, cannabichromene and cannabinol was shown in both samples and quantitative estimation of these cannabinoids appears in the table.

aAverage and standard deviation.
Deceased February, 1973.
Kimura and Okamoto (1970) have studied the seasonal influence which interferes with the content of some constituents in differents parts of the plants.
From our data we may conclude that an increased length of natural light of only 2 hours a day at least doubled the average content of THC and decreased significantly the average content of cannabichromene. Cannabinol content, however, did not reveal significant difference.

pour resumer en gros sous 10 heures de lumiere 1.26 % de thc, sous 12 heures de lumiere 2.94%
j'ai retrouvé et viens de recopier un grand morceau d'un chapitre qui parle de THC ect, mais j'ai mis trop de temps j'ai du me relogger et j'ai tout perdu
