when to harvest cannabis seeds

Personally, I prefer the following high success rate germination procedure. I take a glass of lukewarm water and gently chuck in the seeds. Then, I leave them alone someplace dark for 12 to 24 hours. I check them regularly: as soon as I see white tips (taproots) emerge, I carefully pick up the seed with a pincer. I place them root-down into a pre-watered grow plug. I use a water and root stimulator mix following user instructions. Then I put the plug and seed in my propagator and patiently wait for them to surface.

Welcome to the sequel to my first post on growing cannabis at home. In it, I explained what you need to get set up for your very first weed grow. After that, you ordered your perfect seeds to work with. That means we’re all ready to roll up those sleeves and get growing! Your weed plants will go through a lot between the moment your seeds germinate and that first taste of your harvest. In this blog, I’ll discuss the stages you’ll go through before you get to enjoy the fruits of your very first cannabis grow at home!

Baby Steps: Germinating Your Weed Seeds

I continue the growth stage until I’m happy about plant size. It usually takes about three weeks, but my perfect size will differ from your ideal dimensions. It’s all up to you, and when you’re done, it’s time to start growing flower buds. Let’s start the flowering stage!

There’s all sorts of techniques to keep plant size under control.

I hope I helped you make the best start at managing a first ever cannabis home grow! I wish growers all the best and lots of fun, as well as heaps of homegrown weed of course. Should anything go wrong along the way, then don’t despair. I’ve run into some minor setbacks myself – and major ones too.

The most fulfilling part of growing your own cannabis is the harvest!

FAN LEAVES WILL TURN YELLOW

There is a large debate surrounding exactly when to harvest buds. There are general guidelines for each cannabis subspecies in regards to the optimal time. Indica strains are usually ready after 8 weeks of flowering, and sativa strains after a 10-week period of flowering. Autoflowering strains often take approximately 10 weeks after the seedling stage. Although these guidelines can be helpful in estimating when harvest time may occur, more attention to detail is required to make sure you are spot on with your timing.

It doesn’t take much anatomical knowledge to identify this change. Fan leaves are the large and wide leaves that serve as energy-forming solar panels for your plant. During the vegetative phase, yellow leaves aren’t a good thing and often point towards nutritional deficiencies. However, if your plant is loaded with flowers, fan leaves will begin to turn yellow and die as much of the resources are directed towards the buds. This is an easy to spot and surefire sign that harvest time is close.

A jeweller’s loupe is a small hand-held magnifying device that can be used to get up close and personal with trichomes. Additionally, a digital microscope will provide a clearer image of the state of your trichomes, but at more of a cost.

Earlier on in the flowering phase, trichomes will appear translucent, meaning they are still developing and should be left to mature. When approximately 60% of the trichomes develop a milky look, they are ready to harvest. It’s at this stage where they will produce the most significant high . However, some growers wait until up to 90% of trichomes move past this milky look and become amber, as this will cause the buds to develop a more stoning and sedating effect.

This is the stage to pot up photoperiod plants into final containers, at least a couple weeks before switching to bloom or prior to Summer outdoors.

The way these differ from photoperiod plants is written in the name. Regardless of whether you feel the plant is ready, it’ll start flowering at a certain time depending on the strain’s genetic programming. In one sense, these plants are easier for novice growers because there’s less to think about in regards to light coverage and cycle adjustment. On the other hand, due to the limited vegetation time, you have fewer opportunities for mistakes. This isn’t ideal for first-timers, but the fact that it only takes two months from germination to harvest is definitely appealing. Autos tend to produce lower, milder yields than their photoperiod counterparts, but modern advances are bridging the gap.

STAGE 5: HARVEST, TRIMMING, DRYING AND CURING — 1–2 MONTHS

One of the best ways to truly tell if your flowers are ready for harvest is by getting up close and personal with a magnifying device. This visual advantage will enable you to detect minor changes that wouldn’t be noticeable to the naked eye. Some growers choose to use a jeweler’s loupe, which is essentially a pocket-sized magnifying glass encased in a piece of metal. Others choose to use devices such as digital microscopes, which provide greater detail.

Breaking through the germination stage, plants enter the seedling stage next. At this point, they’ll need about 18 or more hours of daily light. After two or so weeks of proper care, though, they’ll be well on their way to robust growth.

Looking for shifts in trichome appearance is the most accurate way to determine the stage of maturity of your crop. Trichomes are hard to miss and appear as a white frosty substance that covers the buds and sugar leaves. Zooming in on these structures will allow you to know how far along your plants are, and whether they are ready for the chop.
