42 Fast Buds is one of the best known names in autoflower seeds, and many US growers search for it by name. This guide explains what the company is, what its own website says about shipping to the US, how its autoflower seeds differ from photoperiod seeds, and what to check before you buy from any seller. We do not link to seed shops, and Kind Seed does not sell or rate 42 Fast Buds products here.

What is 42 Fast Buds?

42 Fast Buds, often called Fast Buds, is a seed breeder. Its own site describes it as “an international cannabis seed company developing high-performance genetics for growers worldwide, with a primary focus on autoflowering cannabis.” The site also says, “42 Fast Buds is a breeding company, not a reseller,” and states that all of its seeds are feminized.

According to its own FAQ, the range has three groups: autoflower seeds, fast flowering photoperiod and autoflower crosses, and limited photoperiod releases. Strain names usually end in Auto when the seed is an autoflower.

Does 42 Fast Buds ship to the US?

This is the question that most US buyers have, and the company’s own pages do not give one clear answer as of October 16, 2026.

• The FAQ on its main site says: “US orders ship from Los Angeles.”
• Its US delivery page says: “US / CA: – Unfortunately we are unable to ship to the US or Canada. But check out our distributors”

Because those two lines conflict, check the checkout page and contact the company’s support before you order. The delivery page points US buyers to its list of authorized distributors, and the main site says its products are sold through distributors worldwide. If you buy from a distributor, read that seller’s own shipping and guarantee terms, since they may differ from the breeder’s.

How 42 Fast Buds autoflowers work

Autoflowers are plants that start flowering on their own schedule. Cornell University researchers explain that most hemp grown for CBD or CBG “will only terminally flower when the night is long enough,” but autoflowering cultivars “will flower regardless of day/night length.” Cornell has mapped one genetic locus behind this trait, which it calls Autoflower1.

That trait shapes how you grow them:

• Fast finish. Oregon State University Extension notes that autoflower varieties are “generally ripe to harvest around 75 days after planting, while full-season types require closer to 120 days.” Each strain listing gives its own breeder stated time.
• Early planting outdoors. OSU Extension explains that because autoflowers do not need the late summer day length cue, “they can be planted earlier in the year.”
• Less time to recover. Autoflowers keep moving through their life cycle, so stress such as a late transplant can cost yield.

Fast flowering strains are a different story. They are photoperiod plants bred with autoflower genetics, so they still need longer nights to flower.

Reading 42 Fast Buds strain listings

Listings on breeder sites usually show cannabinoid levels, size labels, flowering time and genetics. Read these as breeder claims. They describe results in good conditions and can change from plant to plant. When you compare listings, focus on:

• Total time from sprout to harvest, which matters most for an outdoor season.
• Stated size, which tells you whether the plant fits your space.
• Seed type, which for this breeder is always feminized according to its own FAQ.
• Germination terms. The breeder’s site says it provides a germination guarantee and that support will “review the case” if you followed its recommended method. NC State Extension notes that “there isn’t a minimum standard germination for hemp,” so the seller’s written terms are what count.

How to buy 42 Fast Buds seeds in the US

1. Check your state and local rules. Seed and home grow rules vary by state and locality.
2. Confirm shipping before you pay. Because the breeder’s own pages conflict on US shipping, confirm at checkout or with support, or use a distributor that states US shipping on its own site.
3. Read the guarantee terms. Note the method you must use, the time window and the proof you need, such as photos and an order number.
4. Check the seller’s address and contact options. A clear way to reach support matters if an order goes wrong.
5. Start small. Order a small pack first, grow it, and keep notes before you buy more.
6. Store seeds well. Keep unopened seeds cool, dark and dry until you are ready to plant.
7. Germinate with the seller’s method. Guarantees often depend on it.

Other ways to find autoflower seeds

Legal note

Marijuana and hemp are both Cannabis. Virginia State University Cooperative Extension explains that marijuana was bred for its production of cannabinoids, while hemp was bred for fiber and seed. Seed and home grow rules vary by state and locality, so check the rules where you live. A change to the federal hemp definition currently does not apply before December 11, 2026, and rules may change, so check current federal and state law.

The company’s own FAQ says all Fast Buds seeds are feminized. Feminized seeds are meant to grow female plants, but results are not certain, so read the seller’s terms.

Under current federal law, hemp, including its seeds, is cannabis with 0.3% delta-9 THC or less on a dry weight basis, and hemp is not a federally controlled substance. State law still decides whether you can buy, possess or grow cannabis seeds, so check your state and local law before you buy or plant. A change to the federal hemp definition currently does not apply before December 11, 2026, so check current federal and state law.
