If you’re growing photoperiod cannabis under 18 hours of light and otherwise suitable conditions, there is nothing that will tell your plant when to enter flowering.
4. Flowering stage (5–16+ weeks) – This is the reproductive stage of cannabis when it begins producing buds. How long your cannabis needs to ripen its flowers greatly depends on the strain you are growing. Fast-flowering indicas can be ready after about 55–60 days of flowering, whereas some sativas could take a few months for their buds to ripen.
If you ask most growers how long it takes to grow weed, chances are you won’t get a straight answer. This is because the time it takes to grow weed can depend on many factors such as strain genetics, growing methods used, and certain environmental factors. All things considered, it could take anywhere from 8 weeks to 7 months until you can actually smoke your harvest. Below, we offer some guidelines on the timescales involved when growing weed, so you can plan your grow accordingly and reap the final rewards!
PREPARATION TIME BEFORE YOU GROW
• Preparation time before you grow (0–4 weeks) – The time you need to get your seeds and supplies together, and to get your grow room ready.
How long you can keep your cannabis plant in the veg stage will primarily depend on how much space and energy (electricity) you have. Obviously, you want your plant to grow as big as possible so you can enjoy a big harvest, but you also don’t want it to get so tall that it outgrows your tent or grow space. Having an approximation of your plant’s final height is essential in this case, as some spindly sativas can easily double their height during the flowering stretch. The same goes for some modern hybrids and even indicas.

In this guide, we will look at the different stages involved with growing feminized photoperiod cannabis indoors. As we want to give you an idea of what to expect from the moment you decide to start growing to when you can finally enjoy your self-grown stash, we are also including preparation time and drying and curing time for your weed post-harvest. The following are the stages of a typical cannabis indoor grow:
What if time is not an issue?
Additionally, many growers prefer to ‘cure’ their buds for longer than the 2-week minimum for added flavor and bag appeal, which accounts for why some grows could take several months from seed to smokable harvest.
The time from seed to smokable harvest averages 3-3.5 months for me with a strain like Northern Lights, where I grow the plants for 3-4 weeks in the vegetative stage, growing with cheap, regular CFL lights in coco coir, and with that setup I can get a few easy ounces per plant.
How to grow marijuana as quick as possible:
Strains from warm climates like Haze 1 tend to have long flowering periods before their buds are ready to harvest, adding weeks or months to the time needed. Long-flowering strains often produce higher yields than short-flowering strains because buds have more time to grow.
Once your plant is harvested, there is a drying and curing process which takes about a minimum of two weeks before your buds are “ready” for use.
