A question from a fellow grower:
If you were going to supplement your co2, would you use it in vegging the plants or in flower? I’d love to do both, but can’t afford it.
Roberts April blog post was really good (THC and cannabinol)… but there was this part.
While the plant is still living and growing, a large percentage of its THC remains in THCA form, which is one of the primary reasons that plants must be dried and cured to have strong drug effects. Extra CO2 molecules strongly inhibit the potency of the plant.
