Long before social media, a handful of web forums shaped how people learned to grow cannabis. Overgrow was one of the most important. In the early days of the internet, it gave growers and breeders a place to share techniques, photos and genetics knowledge at a time when growing was illegal almost everywhere. The original site shut down in the mid 2000s, but its influence lives on in today’s forums and seed catalogs, and the Overgrow name has since returned as an active community. This guide covers why Overgrow mattered, what the forum looks like now and how to get the most from it.

Why Overgrow mattered

In the late 1990s and early 2000s, most growing information came from a few books, magazines and word of mouth. Overgrow changed that. It brought growers together from many countries to post grow reports, ask questions and compare results. A few things made it special:

• Grow reports with photos. Members documented grows in detail, which turned private experience into shared knowledge.
• Breeding discussions. Breeders and hobbyists talked openly about selecting parents, stabilizing traits and testing seeds.
• Strain history. Members traced where popular strains came from, helping preserve stories about landrace and classic genetics.
• Community culture. A tone of mutual respect and learning encouraged careful, honest posting.

Many strains and breeders that became famous later first gained attention in forums like Overgrow.

The shutdown

The original Overgrow went offline in 2006. At the time, it was widely reported that the operators shut it down because of legal pressure on cannabis websites and the people behind them. Members scattered to other forums, and many of today’s grow communities grew out of that diaspora. For a generation of growers, the shutdown was a reminder of how risky it was to share growing knowledge online.

Overgrow today

Years later, the Overgrow name returned as a new forum. It aims to carry on the original spirit with a focus on growing, breeding and genetics. Like any forum, it has its own rules, culture and regulars. Before you join, read the forum guidelines and spend time browsing.

What you will find

Today’s Overgrow typically includes:

1. Grow sections organized by indoor, outdoor and specific methods.
2. Breeding and genetics discussions for people interested in making their own crosses.
3. Grow diaries where members follow a grow from start to finish.
4. Troubleshooting areas for plant problems.
5. Community and off topic areas.

The breeding focus sets it apart from more general forums. If you are interested in genetics, open pollination, selecting mother plants or preserving old strains, it is a good place to learn.

Getting the most from Overgrow

Learn the vocabulary

Breeding discussions use terms that confuse newcomers. A few to know:

• F1, F2 and so on. Generations of offspring from a cross.
• Backcross. Crossing offspring with one of its parents to strengthen certain traits.
• Phenotype. How a plant looks and grows, shaped by its genes and environment.
• Pheno hunting. Growing many seeds and selecting the best plant.
• Landrace. A strain that developed in a specific region over a long time.
• Feminized. Seeds bred to produce female plants.

Read old threads

Some of the most useful information is in older posts. Long running breeding threads show how a line developed, which traits were hard to fix and what testers found.

Contribute

Forums depend on members who share. Post your grows, including failures. If you test seeds, write honest reports.

Stay private

Use a username unrelated to your real identity. Remove location data from photos. Do not share your address or details about your plant count, even where growing is legal.

How breeding knowledge helps home growers

Even if you never make a cross, understanding breeding helps you choose seeds. You will know why some strains are more uniform than others, why feminized seeds are popular and what to expect when you grow a new hybrid. You will also understand why a strain name alone does not tell you everything. Two plants with the same name can look and grow differently.

A word on legality

Growing laws vary by state and country. Forum members may live in places with very different rules. Before you grow, check your state’s laws on home cultivation, plant counts and security. Seeds are a separate legal topic. Federal rules on hemp and cannabis seeds are changing, and a new federal definition that excludes certain seeds is set to take effect on December 11, 2026. We explain what that means in our seed law guide.

Where to start

If Overgrow’s history inspires you to explore genetics, start by growing a few stable, well documented strains and keeping careful notes. Browse our marijuana seeds to find genetics for your space and experience.

Reading a seed test like a breeder

When you read seed test threads, look at how many seeds were sprouted, how many plants were kept and how much they varied in height, smell and flowering time. A strain that gives very similar plants across several growers is more stable. A test from one grower with one plant tells you much less. Note the grower’s setup too, since a strong light and a skilled hand can make almost any strain look good.

Grow legally and responsibly

Home cultivation is only legal in some states, and each state sets its own plant limits, locking rules and rules about whether plants can be visible from a public place. You must be 21 or older to buy seeds from Kind Seed Co, and you should grow only where your state and city allow it. Check your state rules in our guide to the legal requirements for growing weed plants in your state before you plant. Federal treatment of cannabis seeds is also changing, so read our December 11 2026 seed rule explainer before you order. Keep plants and harvested flower locked away from children, pets and visitors, and never drive after using cannabis. This article is general information.

Final thoughts
