Are Real Growers Behind the Brand?
A lot of companies selling cannabis seeds online are distributors. They source genetics from breeders, list them in a catalog, and fulfill orders. The business is logistics and marketing, not cultivation. That is not automatically a problem, but it does mean the strain descriptions and grow recommendations you are reading may not come from personal experience.
When growers are behind the brand, things work differently. They have grown the strains they sell. They know how a plant actually behaves in weeks three and four of flower, not just what the breeder spec sheet says. They drop genetics from their catalog when something does not perform the way it should. That kind of curation only happens when someone has real skin in the game.
Look for evidence of real cultivation experience: grow photos from their own facility, guides written from first-hand knowledge, and a founder story that includes actual time spent growing, not just starting a business.
At Triangle Seeds, Matt Spitzer and Chase Werner have been growing plants commercially since 2013, starting with Endless Sun Farms, a hydroponic lettuce and tomato operation in Raleigh, NC. They founded Triangle Seeds in 2017. Over a million plants and seeds later, every strain in our catalog is one we have grown and believe in. The ones that did not perform are not listed.
Do They Offer a Germination Guarantee?
A germination guarantee tells you something important about how a company views its own product.
If a seed company is confident in their genetics, a germination guarantee costs them very little. Seeds from healthy, well-stored stock germinate at strong rates. The guarantee is easy to honor because it rarely gets triggered.
If a company does not offer one, ask yourself why.
What to look for in a germination guarantee:
- Does it cover the full seed count or just a percentage?
- Are there conditions, such as following a specific germination method?
- What is the resolution: replacement seeds, store credit, or a refund?
- Is the process straightforward, or does it require extensive documentation?
A clear guarantee with a simple resolution is the sign of a company that expects its seeds to germinate and is prepared to make it right when they do not.
Will They Support You During the Grow?
Most seed companies are set up to sell you seeds and move on. The transaction ends when your order ships.
Growing cannabis takes months. Problems come up. Plants show deficiencies. Timing questions arise mid-grow. When that happens, being able to reach someone who actually knows what they are talking about matters more than most people expect before their first grow.
Before you buy from any seed company, test their support. Send a growing question and see who responds, how fast, and whether the answer reflects real growing knowledge or a generic reply pulled from a FAQ.
At Triangle Seeds, we answer growing questions before, during, and after the grow. If you bought seeds from us six months ago and something comes up in week four of flower, reach out. That is part of what we do.
Feminized vs. Regular Seeds
Unless you are breeding your own genetics, you almost certainly want feminized seeds.
Regular seeds produce both male and female plants, roughly half and half. Male plants do not produce usable flower and will pollinate your females if left in the same space, seeding your entire crop. Managing a regular seed grow means identifying and removing males early, which adds complexity most home growers do not need.
Feminized seeds produce only female plants. Every seed you plant becomes a flower-producing plant. For home growers working with a legal plant count and limited space, that matters.
All Triangle Seeds genetics are feminized.
Autoflower vs. Photoperiod
This choice shapes your entire growing experience.
Autoflowers flower based on age, not light schedule. They move from seed to harvest in roughly 9 to 12 weeks regardless of how many hours of light they receive. They stay compact, require no light timing management, and work well indoors under an 18 to 20 hour light schedule or outdoors in almost any climate with a reasonable growing season. They are sensitive to transplanting, so start them directly in their final container and do not move them.
Photoperiod strains flower when the light cycle shifts to 12 hours of darkness per day. Indoors, you control when that happens, which means you control how long the plant spends in vegetative growth and how large it gets before flowering. Outdoors, the shift happens naturally in late summer. Photoperiods take longer overall, typically 4 to 8 weeks of vegetative growth plus 7 to 10 weeks of flower, but they give you more control over yield and structure and respond well to training.
If you are a new grower growing outdoors and want the most straightforward path to harvest, an autoflower is usually the right call. For a larger indoor setup or more control over yield, photoperiod strains are worth the extra time.
Our strain selection guide includes filters for grow environment, experience level, and genetics type.
Does the Company Ship to Your State?
Cannabis seeds sold under the 2018 Farm Bill are federally legal to purchase and ship nationwide. Triangle Seeds ships to all 50 states.
That said, home cultivation laws vary by state. The seeds are legal to buy, but whether you can legally plant them depends on where you live. Check your state’s rules before you grow. We have guides for every state at cannabis seeds by state.
Things That Matter Less Than You Think
Catalog size. A seed bank listing 3,000 strains is not necessarily better than one listing 30. More listings often means more genetics added for marketing reasons rather than grow performance. A smaller, curated catalog from growers who have actually grown the strains is usually the more reliable option.
Free seeds with every order. Common in the industry. Free seeds from unknown genetics with no grow data behind them are not worth much. Do not let a freebie promotion drive your decision about where to buy.
Stealth packaging. Seeds sold under the 2018 Farm Bill do not require stealth packaging. If a company leads with this as a selling point, it is worth asking why.
Frequently Asked Questions
Is it legal to buy cannabis seeds online? Yes. Cannabis seeds sold under the 2018 Farm Bill are federally legal to purchase and ship to all 50 states. Whether you can legally germinate and grow them depends on your state’s home cultivation laws.
What is the difference between feminized and autoflower seeds? Feminized refers to the sex of the plant. Feminized seeds produce only female plants. Autoflower refers to how the plant triggers flowering, based on age rather than light schedule. A seed can be both feminized and autoflowering, which is common. Most seeds sold for home growers are one or the other.
Do I need a germination guarantee? You are not required to have one, but it is a meaningful signal of seed quality. A company confident in its genetics will offer one without hesitation.
How do I know if a seed company actually grows their own genetics? Look for real grow photos from their own facility, cultivation guides written from direct experience, and a founder story that includes actual growing history. You can also reach out directly and ask.
What should a new grower start with? A feminized autoflower is the most forgiving starting point for most new growers. They finish faster, stay compact, and do not require light schedule management. See our strain selection guide for recommendations.
Does Triangle Seeds ship to my state? Yes. We ship to all 50 states. Check cannabis seeds by state for your state’s home cultivation rules before you grow.
