how accurate are breeders harvest time info?

Under 'ideal' conditions, sufficient light, overall health of plant and lack of pests that harvest typically is within a 2 week period of the suggested time frame depending on the type of effect you are wanting. ^If wanting an upbeat effect with a lower THC quality you would harvest when the trichomes are milky, with some clear and no amber. ^For a more couch lock relaxing effect harvest when 85% milky, 10% clear, 5% amber. ^For a more medicinal, CBD effect with lower quality of THC harvest with a higher amount of amber. I found mine seemed to be at optimal harvest 2 weeks earlier under my Blurple Light and my plants under my standard full spectrum LED bulbs is ready 1 week past the suggested harvested window. Great Luck & Happy Growing 🍃

I agree with The8thChevron. You almost always have to account for more time, I think it's really rare for someone to harvest their buds with the flowering time the breeder provides. But anything is possible, treat each plant as an individual🌱

Breeders give you info on the shortest flower time with ideal conditions. Most of us give them an extra 2 weeks to ripen.
