from seed to harvest weed

Take meticulous notes on when and how you perform each step, as well as what the weather is like. Other notes can include how much water you give plants, at what intervals, and how much nutrients you give them. Pictures will also give you a better sense of how your plants look along the way.

As roots develop, the stalk will rise and you’ll begin to see the first iconic fan leaves grow, at which point your cannabis plant can be considered a seedling.

We can’t stress enough that the timeframes in the above graphic are ranges of time for the Northern Hemisphere. You’ll need to adjust them based on your specific region and local weather and climate.

Be sure to keep a grow journal to track the progress of your plants. Looking back on your notes will help you learn from mistakes and maximize the quality and quantity of your buds.

Harvest happens sometime between September and November. This depends on your local climate, as well as the weather that particular year—one year it could be the end of September, the next, end of October, and growers in the Pacific Northwest will have to pull down their crops earlier than those in Northern California.

Have you ever heard of topping, super-cropping or lollipopping? Using these techniques you can train cannabis or manipulate the shape of the plant. Growers use them to develop stronger plants with more buds. Opinions vary, however, on whether these techniques actually deliver results. They are only necessary for special cultivation methods such as the Screen of Green (SCROG).

Once the plant produces the full count of leaflets for each new leaf, the seedling stage is over.

Plants are living beings. They are at the base of the evolutionary tree, they heal our bodies and souls, they delight our senses. I think all our readers know by now which is our favourite plant: Cannabis sativa L. – a fantastic crop and medicinal plant, and one of the oldest plant genera in the world.

2 – Seedling stage (2 to 4 weeks)

Leafy plants like a healthy soil that is rich in nutrients. The production of chlorophyll and proteins depends on a supply of nitrogen. It is worth investing in the right kinds of fertiliser or even producing them yourself.

As it grows, the plant also needs more water. Young plants are best watered close to their stem, but later on water should be distributed more widely so that the tips of the roots can absorb water more efficiently.

A quick glance is usually enough to determine the current stage. Over time, it is not just the appearance of the plant that changes, its needs also change. Different stages require different quantities of light, water and nutrients. Furthermore, if you want to determine the sex of the plant or prune it, it is useful to know which stage the plant has currently reached.

Meanwhile the plant will grow its first “real” leaves with the characteristic marijuana shape.

Once you confirm you’ve got a ripe marijuana crop on your hands it’s time to break out the trimming scissors and get harvesting. After two weeks slow drying in paper bags or hung up, at room temp and approximately 50% RH, you’ve got a stash.

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.

If you opted to use the dry trimming method, then your flowers will be ready to cure straight away. If you chose wet trimming, then your flowers will need to be properly dried before you go on to cure them.

STAGE 3: VEGETATIVE PHASE — 2–8+ WEEKS

Outdoors Mother Nature dictates the grower’s schedule and flowering will only commence in Summer/Autumn as the hours of daylight naturally diminish, making for a longer more gradual flowering period. Weed growers in the Northern hemisphere don’t refer to October as “Croptober” for nothing.

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.

Photoperiod strains can be kept in vegetative growth indefinitely so long as 18+ hours of light and suitable conditions prevail. This is what allows indoor growers to keep mother plants for years and why outdoor grower’s plant in springtime. Indoors or outdoors 18+ hours of light facilitates taking cuttings too.

It’s always best to evaluate if a cannabis plant is ready to harvest by taking a closer look at those resin dripping buds. Using an inexpensive scope to zoom in on those resin heads to make sure they are milky and amber rather than clear removes all the guess work.
