When to Harvest Marijuana

How do you know when to harvest marijuana?

when to harvest marijuanaThe time when to harvest marijuana can be anywhere between 6-12 weeks after the plant starts flowering, then it should be ready for harvest. I know that sounds vague, so we’ll have to look for some visual cues. Look for the white hairs to turn red, orange or brown, and the false seed pods (you did pull the males, right?) to swell with resins. When most of the pistils have turned color, the flowers are ripe to harvest.

The male plants will be taller and have about five green or yellow sepals, which will split open to fertilize the female plant with pollen. The female plant is shorter and has a small pistillate flower, which really doesn’t look like a flower at all but rather a cluster of white hairs. If you don’t want any seeds, just good dope, you should pick the males before they shed their pollen as the female will use some of her resin to make the seeds.

Should I Harvest Early, or Late? What’s the Difference?

If you harvest early, the THC content will be higher, therefore it will produce more of a cerebral “head high”. When a plant is in the later stages of budding, the THC starts to turn into what’s known as CBD. CBD is thought to produce more of a body buzz then THC. The high will be less clear and will sometimes make you feel stupid. So the later you wait to harvest, the more CBD you’ll be smoking.

I would recommend experimenting a little, no I don’t mean you need to find a white lab coat, just try harvesting at different times and “feel” the results. Try and find a balance between the two. When 50-65% of the hairs turn color, it’s usually a good time. The right time to harvest marijuana is up to you.

Don’t touch those buds! Touch only the large fan leaves if you want to inspect the buds, as the THC will come off on your fingers and reduce the overall yield if mishandled.

Harvesting When Growing to Sell

When growing marijuana for the purpose of selling, many growers will let the buds over-ripen, which causes the weight to increase due to the extra resin in the seed pods. Some growers wait far too long, and the THC content is so low it’s hard to catch a decent buzz. If you decide to harvest marijuana late for weight purposes, remember to cut a few buds for yourself. Just make sure you cut from the middle or the top.

    Thanks for sharing info. This is my 5th grow, and i finally got me some microscopes. My plants seem to mature later then it is written on the seed package, That might have something to do with me using hydroponics and organic nutrients. My last grow was the worst ever i used wrong soil , plants never matured , lost all leafes and it tasted more like peoples pot rather then mary jane. I strongly recommend searching chinesse websites for microscopes.. Buy only copy products, never original.. they are just as good, and you only give like 5 bucks for 5 microscopes and jewlery lupes with UV light and white light, and the shipping was free .. I donno if i can link you anything here. But im sure you will find some chinese importer selling online with free shipping and stuff. It’s same microscope as original only difrence is the logo on it, same quality i had original comparred (original cost like 4-5 times more same image quality and same magnification) These lupes are cruciual to determine when to harvest.

  4. i have not grown anything is many years and probly forgotten more than anything ,,looking for the simplest way to grow good maryjane

    • I grow veg in a kitchen cab with 2 cfls-100watt–theyare tight and with good f\oil grow like champs. My gor room is 2-by 2 by 8.I let then gor 3 months and then in and always have 1 a month behing -when you pull the one the other will take off-i also use a 50watt quad red led light-works great-4 cfls-23 watt-they give off 1200 lumens-more the lumens the more the tigh tbuds.i cut hole in top right and have fan at 3 ft. pointing right at it pulling heat out. stays at 73-has seen 84. working great-let the plant totally dry out and only use organis fert-at 1 third the strenth always never more-spray the leaves every day —–once a week with miracle grow-high nitrongen-then clear bottled watter and flush 3 times and add potassium and watch them flower. good luck steamer

  5. do weed have to get sticky before harvest

  6. Indica vs Sativa. I’ve spent a lot of time choosing seed. Thought I’d try several different strains some Sativa and some Indica. Now I read that if you let your Sativa go too long the Sativa high get more like Indica high. Will I see more difference in the two strains or more from harvest timing of only one of the strains.

  7. The crystals start clear then turn milky when THC is ripe. Then as the THC turns to CBD The THC turns amber when the amber turns dark red your definitely couch-locked and feeling no pain

  8. 1st time seeing this info new to me lol had always read when about half of hairs turn its time. never knew specifics of the chemical changes makes me go hummm..time for some experimentation.

  9. I am Disabled and have Chronic Pain. I am on heavy drugs, that keep me stupid and sleepy. This is the first time I have tried growing. The plants were short and had magnificent buds with no big leaves. I left them too long, I am afraid, because new leaves began growing out of the buds! I purchased the seeds on line and they were supposed to be White Widow. There were a few white strands in them, but nothing like the photo’s on the web site. I have cut them down, after reading your blog and am hoping they will not knock me out! Peace & Love~
