If you want six total cannabis plants to harvest for buds and are growing from regular seeds, start with about 4 times as many, or 24 seeds. Some won’t germinate and some will turn out to be males, and then you’ll want to discard down to the six best phenotypes. If growing feminized seeds, you can probably start with about twice as many seeds in this case (about 12); a couple won’t germinate, and then discard down to the six best phenotypes.
Seeds can come feminized, meaning you can just put them in soil and start growing for buds. These seeds are guaranteed to be bud-producing females and growing them cuts out the step of having to sex out plants and discard the males.
If you buy a packet of regular seeds, they’ll come with a mix of males and females. A lot of cultivators prefer to grow these because they haven’t been backcrossed—essentially inbred—as much as feminized or autoflower seeds. You’ll need to sex out the seeds once their reproductive organs show during the flowering phase and discard the males—because they don’t produce buds and will pollenate females, resulting in seeded flowers.
How many seeds should I buy? Are they all going to survive?
Seed banks exist outside of the US and can sell them for “souvenir purposes,” but it is illegal to bring seeds into the US and Customs will seize any cannabis seeds they find in packages or on a person.
Autoflower plants change from the vegetative to flowering state with age, not the changing of their light cycle. They have a short grow-to-harvest time and can be ready to harvest in as little as 2 ½ to 3 months from when you put the seeds in the ground. The downside is that, typically, they are less potent, but autoflower seeds are great for people who want to grow cannabis but don’t want to spend a lot of time doing it.
Even one weed plant can produce a lot of buds come harvest time, so make sure you grow a strain you like. Note strains you enjoy when you pick something up at the dispensary or smoke with friends, and look for seeds of it when you want to start growing.
An inexperienced breeder might cross a male and a female one time and sell the resulting seeds as a new hybrid strain, but professional breeders usually put their strains through several rounds of backcrossing to stabilize the genetics and ensure consistent plants that reflect those genetics.
We want to restate that nothing contained in this article should be taken as legal advice. We are not lawyers and do not know the ins and outs of the law. And when it comes to the laws governing cannabis, even lawyers generally have no real idea of what is going on.
Buying or possessing weed seeds is illegal in New Zealand. The only way to buy them if you live in New Zealand is to order them from an online seed bank. Many don’t ship to NZ, but Marijuana Seeds NL ships all over the world, so they’re your best bet here.
ILGM still ships there, however. They do a great job of concealing the seeds with their stealth shipments, so most end up getting through. And if they don’t, they will send you a new shipment.
Is It Illegal To Send Other Seeds In The Mail?
Obviously the legality of mailing marijuana seeds varies from one location to the next. We can’t cover every country, much less every region in every country, in the world, so we’ll focus on those countries where the majority of our readers reside. And number one, by far, is the United States
But you can’t always ship them or receive them in the mail.
If buying seeds in Europe, we generally recommend one of the log-established banks. The aforementioned Seedsman is good, but our favorite is Marijuana Seeds NL.
You can basically have seeds delivered anywhere in western Europe. Spain is the most lax country, which is why several seed banks are located there, along with Holland and the UK. Due to the treaty, you should be fine in eastern Europe, too, but most eastern countries are a lot more strict when it comes to cannabis.
