those aren't ready my friend. judging from the amount of young and immature pistils that are still showing. Plus, I see hardly any amber trichs. I can see a couple here and there.. so I mean, technically, yes, you could go ahead and harvest them.. but you won't get the full effect from the product if you harvest this weekend. If I were you? I would give it another week worth of flowering.. then recheck them and see where they are at that point in time.
once again, for like the 57th time... I will try and help educate you noobie growers out with posting this article. This is the LAST time I'm going to post this article... period.
Is it ready yet?: This is by no means meant to be the definitive guide to knowing when to chop your plant, only my views on the subject.
Its my personal opinoin that 90% of the noobie growers on this site (And probably in general) harvest too early. By letting the plants go a little longer you're ensuring that the've plumped as much as they're going to.
Despite popular opinion to the contrary(and don't fool yourself, the jury is still out on this one) Recent studies have shown ;contrary to what was previously believed, that THC itself (And its predecessor THC-A) are quite guilty of causing the confusion and drowsiness associated with burnout and other cannabinoids (our friend CBN, and a handful of others) to be the catalyst (along with THC) to being 'high' rather than 'baked'
Regardless, whether or not theres any substance to the aforementioned study, its easy to get the high you want.
If you want a soaring 'cerebral' high: Get yourself a tropical sativa that contains a high level of THC-V and grow it until it is ripe.
If you want the narcotic couchlock stone, grow a rugged indica until its ripe.
Notice a pattern of growing it until its ripe? Its a really good rule to live by.
OF course we have to remember that there is more to a good high than just THC. At last count there are at least 66 cannabinoids, and we don't know what most of them do.
Now alot of people will tell you that you should harvest based on the colour of your trichomes. But (again, in my opinion) that is far too simplistic and there are too many variables to make that an effective strategy. I've made that point a million times before and i'm not going to re-hash it here,(maybe just a bit) but rest assured there is more to the picture than just trich colour.
A ripe marijuana plant will be filled in, will have an amber tinge to the buds. The pistils should have browned (or orange-d) off and receded into the buds. The seed bracts should be swollen and the trichomes should be sticking straight out with bulbous ends. Also, because you're coming close to the end of plant's life cycle, the leaves should have yellowed off and started to die.
Another very important (imho) reason to let your plants mature is Terpenoid production. Terpenes are responsible for alot of the complex (And enjoyable) flavours that cannabis produces. Some of the most intense flavours are produced on the "downslope" of cannabis's life cycle. My personal experience with this first came when i was growing GH cheese. One of the plants i harvested at 8 weeks and it tasted pretty nice and had pretty dense buds. The other i grew until about 9 1/2 weeks and it had most amazing, sour, skunky, delicious taste with rock hard buds.
If I could offer one piece of advice on picking the right time to harvest, it's all about watching the pistils. Not so much the colour, but the movement. They should have receded into the bud and the seed bracts should be swollen.
Follow this information correctly.. and you won't be disappointed. I know there are alot of incorrect articles going around. Hell, IMO, there is WAY TOO MUCH incorrect information floating around out there on the interweb.. and its hard to find correct information. However, this article.. is from my personal experience.. 5 years worth of growing.. and I just shared with the people that read this, how I personally check my plants to see if they are ready for harvesting. Again, keep this article somewhere safe where you can come back for future references. Lastly, once again.. follow this information, and you WILL NOT harvest your plant early.. but you have to MAKE sure you remember these important things in order to have a full ripe harvest.
Thanks for your time and thanks for reading.
Remember the following and you'll do great each and every harvest.. never worrying about an premature harvest again:
Maturation - Eventually the pistils start to turn color from pale white to red or brown At the same time the flowers close up, forming false seed pods. The small glands on the flowers now start to grow. These are called stalked capitate glands and are composed of a tiny stalk supporting a thin clear membrane. As THC is produced near the site, the membrane swells with the potent liquid. The membrane stretches and the gland takes on the appearance of a mushroom. When the glands have swelled and the pistil has receded into the false pod, the bud is ready to pick.
