how log it takes to sprout a marijuana seed

First, make sure you use the correct type of soil, either gently fertilized potting soil or a seed starter with a pH level of approximately six (6). The soil contains the right acidity and enough nutrients to strengthen your young cannabis plants for the first two weeks. Be careful not to add more nutrients, or you risk overfeeding and killing your seeds.

To employ water germination, fill a glass with tap water and let it sit until it reaches room temperature or around 65 degrees Fahrenheit. Add two to three plant seeds per cup and allow them to sit, watching for any changes. Change the water to fresh tap water every two days, making sure it stays at room temperature.

How to germinate seeds in soil

While many plants can be germinated in the ground, cannabis seeds are fragile enough that you should germinate them before planting.

Monitor your soil every day and keep it moist. Within four to seven days, you should see tiny stems sprouting from the soil.

If you’re one of those people that have to have control over everything you might find yourself wondering how long cannabis seeds germinate. The long and short of it is that it usually takes 24 to 48 hours for the cannabis seeds to germinate. If they are placed somewhere moist, warm and dark, like a cupboard or in a propagator. These are ideal places for the Cannabis seeds to germinate and they will crack out of their protective shells.

After another two days, they should have a pair of leaves then continue growing for another two weeks until they begin the vegetation period. If you are concerned that the seed cover is still on the leaf or concerned about how long the cannabis seed germination will still take, just remember the more warmth and moisture (not dampness) will accelerate the process for the Cannabis seeds to germinate and within 24 to 48 hours it should be completely out of its shell.

So now you know how long cannabis seeds germinate, what will happen after?

So, after you’ve bought seeds and equipment, grown a plant from seed to harvest, trimmed, dried and cured your buds, that brings us back to the original answer…

Vegetative Stage
Vegetative Stage: 4-8 week average (but if you want big plants it may take longer)
The length of this stage is a matter of personal preference. Most cannabis plants won’t start flowering until they’re at least 3 or 4 weeks from germination, but after that you get to choose how long your plant spends in this stage (except auto-flowering strains, which automatically start flowering in 3-4 weeks from seed). Except for auto-flowering strains, you have total control over the vegetative stage because you’re the one to ‘flip the switch’ and get your plant to enter the next life stage: flowering.

The size your plant achieves in the vegetative stage has a very large effect on your final yields since bigger plants produce more bud sites than smaller plants. However, you need enough light to cover all the bud sites or they will never develop properly. Light is like food for bud growth!

Here’s a list of some of my favorite and best cannabis strains by the length of the flowering period:

This plant didn’t spend any time in the Vegetative Stage. It was given 12-12 lighting almost immediately after sprouting. It’s so small that it spent its whole life in a solo cup, and its only light came from CFLs. I weighed down the bottom of the cup so it didn’t fall over. It ended up yielding about 0.75 oz.
