how long to germinate weed seeds before planting

Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.

Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.

Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.

But if the seed you found looks decent, you might as well germinate it and see what sprouts.

Is a bagseed good or bad?

Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.

Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”

If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.

Pros and cons of growing autoflower

Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.

Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.

Fill your container with pre-moistened soil and create a hole about a half-inch deep for your seed. The tip of a pencil works well for making the right sized hole. The seed should be about a quarter-inch below the surface.

Place your germinated seed, root down, into the hole and cover lightly. Do not pack the soil on top of the seed; a light protective layer of soil is all that is needed.

Now, on to potting (no pun intended). A healthy seedling will be ready for transplanting into larger container, with richer soil, in about a month. A 16- to 20-ounce container is ideal for a seedling’s first home (many growers use a Solo cup). The container must drain, so punch some holes if needed.

Cover the plate with an upside-down plate or pot lid. A plastic bag or plastic wrap also works. Don’t make the seal tight—you want to leave some openings to allow air flow.

Take great care handling seed and seedling. Most flower and vegetable seeds are simply planted directly in the soil, but because of the value of cannabis seeds, germinating seeds prior to planting is encouraged. Growers can achieve a much higher survival rate by germinating in a non-soil medium and then transferring the seed to soil once the tap root has emerged from the seed.

Keep the germinating seeds away from direct light. For best results, keep them at about 75 degrees Fahrenheit. A radiant heat source, like a heating pad, helps expedite the process. If you’re using a heating pad, be sure to keep the heat setting on low and place a folded hand towel between the heating pad and plate: Direct contact between the plate and heat source can cook your seeds.

If possible, get feminized seeds. Because female pot plants produce the bodacious bud that cannabis connoisseurs crave, starting with feminized seeds will produce more buds when the plants mature. Feminized seeds won’t provide 100% female plants, but they will greatly increase your odds from the 50-50 chances of a standard seed selection.

And maybe you have been using trial and error but ended up thinking, “Why won’t my marijuana seeds germinate?”” Truth is, you’ve likely been making some mistakes without knowing it. You can increase your results, although some seeds inevitably will be duds. No one can attain 100% germination, but there is room for improvement regardless.

How long does it take to germinate marijuana seeds? Typically, it will take anywhere from a couple of days to up to a week to see your seeds start to turn into plants.

A clear plastic cover on the top keeps the warmth in. You can make one of these at home or purchase one inexpensively at your local nursery or online.

Select the Right Seeds

If you choose the seed route, you will want to know the best way to germinate marijuana seeds. Experimenting with marijuana germination is your best bet for determining what’s right for you, since even seasoned growers often argue about the best methods for germinating marijuana seeds.
