It's not what I consider harvestable, it's when the plant is actually considered ready. If you want to harvest early that's cool. Telling someone their plant is ready when it's not hummm what's that oh your opinion. Well bud atleast my opinion is accurate, yours is based on your personal preference. If someone wants to harvest like you, it really doesn't matter what weed they grow. Harvesting early for a speedy head high can be done with any and all plants. Harvesting early for a speedy high is personal preference and incorrect, in order to get each plants effect in full harvesting when ripe is the correct way to grow, harvesting early is personal preference. Now I'll give the accurate way to grow, then it's up to the individual grower on how they proceed. Enjoy your speedy head high weed, but seriously if you want a speedy head high you grow durban poison, green crack, super green crack, amnesia haze, that's only a few sativas that if harvest when ready not early will give you the effects of a speedy high. You're basically not getting the most out of your plants. Not just the effects but also flavor and smell the terpenes. Harvesting before plants ready physically not personal opinion you lose out on all that. You may say you dont, but you obviously dont know what the final product is supposed to look like. You'll also hinder your yield as the last 2 weeks to 4 the calyxes swell. Good luck bud
P.s. which is why everyone but you is saying wait.
