growing weed from seed time

The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flowering.

Cannabis plants are considered seedlings until they begin to develop leaves with the full number of blades on new fan leaves. A healthy seedling should be a vibrant green color.

How long does it take to grow a marijuana plant?

The growth stages of marijuana can be broken down into four primary stages from seed to harvest:

Be mindful to increase your watering as the plant develops. When it’s young, your plant will need water close to the stalk, but as it grows the roots will also grow outward, so start watering further away from the stalk in the soil so roots can stretch out and absorb water more efficiently.

Vegetative plants appreciate healthy soil with nutrients. Feed them with a higher level of nitrogen at this stage.

Photoperiod cannabis strains enter the flowering stage depending on the hours of light they receive. The naturally shorter daylight hours in fall signal outdoor plants to start bloom. If growing indoors, you must initiate the flowering stage yourself by switching your lights to a 12-12 cycle.

How long it takes for cannabis to mature its buds can vary greatly depending on genetics. Some indicas bred for speed can be ready after 5–7 weeks of bloom. However, the average flowering time for most indicas and hybrids is usually 7–10 weeks depending on the strain.

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.

PREPARATION TIME BEFORE YOU GROW

Following a short pre-flowering stage where some plants stretch significantly in length, your plant will stop vegetative growth and put all its energy into producing what you planted it for in the first place: big, juicy, aromatic buds!

• Germinating your seeds
Time: 1–7 days

Germinating your seeds is the first “serious” step when growing weed. If something goes wrong with germinating, such as low-quality or old seeds that won’t “pop”, there won’t be much to grow after all. But you needn’t worry if you get your seeds from RQS, as our cannabis seeds are among the best-quality specimens on the market with the best germination rates.

2. Seedling stage (10–15 days) – The “baby-phase” of your freshly sprouted cannabis plant.
