Can I mention my product or service if I do not ask for money?
No. “No Buying Selling or Trading” bans buying, selling, trading, giving, and asking for seeds, weed, clones, extracts, and equipment, and it also bans naming suppliers.

Works well
- A written grow diary with your own photos, showing what you did week by week and what you learned.
- A detailed question about a specific grow problem, with context about your setup and what you already tried.
- A plain writeup of a mistake that cost you a harvest, explained so other growers can avoid it.
- Helpful answers in other growers' threads, building trust before you ever start your own post.
- A walkthrough of a technique or process, written by hand with enough detail that it clearly took effort.
Avoid
- Posting about selling seeds, clones, extracts, weed, or equipment, or asking where to buy them, under “No Buying Selling or Trading”.
- Naming or discussing seed or clone suppliers in any form.
- Asking people to DM you, in the post or in comments, under “No DM”.
- Using AI generated images or text, or posting memes, under “No AI or MEME”.
- Dropping a thin link with no grow detail or question, which fails “No Low Effort Posts”.
- Asking whether a plant is male or female, which is covered by “No discussion about sexing plants” and the FAQ instead.
What r/cannabiscultivation Is For
This is a forum for sharing information about the cultivation of cannabis. The people here are growers who talk about how to grow plants, from seeds and clones through to harvest. It is a learning space, not a marketplace. The rules make clear that no one is here to buy, sell, or trade anything, so the value is in grow knowledge, shared experience, and helping other growers solve problems.
Rules That Matter Before Posting
The rule that decides most marketing outcomes is “No Buying Selling or Trading”, because it bans any post about buying, selling, trading, or giving seeds, weed, clones, extracts, or equipment, and it also bans naming suppliers. The rule “No DM” means you cannot ask people to move the conversation to direct messages. The rule “No AI or MEME” removes AI generated content and memes, so automated or templated posts are out. The rule “No Low Effort Posts” means a thin link or a one line promo will get removed. The rule “No Bad Vibes” covers how you behave in comments, so keep replies respectful. The rule “No discussion about sexing plants” sends that topic to the FAQ instead of the feed.
What To Post
Post plain, useful grow knowledge that stands on its own, like a lesson you learned, a problem you solved, or a question that shows you did some thinking first. Write it yourself in your own words, because AI content and memes are banned. Put the full value in the post itself rather than asking people to DM you, since DM requests are banned. Give context, detail, and effort, because low effort posts get removed. If you are a founder, the safe play is to participate as a knowledgeable grower and let your reputation do the work, with no sales angle anywhere in the post.
What To Avoid
Do not post anything that touches buying, selling, trading, giving, or asking for seeds, weed, clones, extracts, or equipment, and do not ask about prices or name suppliers. Do not ask anyone to DM you. Do not post AI content or memes. Do not post low effort material with little to no effort behind it. Do not start discussions about sexing plants, because the FAQ covers that. Do not harass anyone or get into personal attacks, because “No Bad Vibes” applies to you too.

Common questions about r/cannabiscultivation
Can I ask people to DM me for details or a demo?
No. “No DM” bans asking for DMs, so invite replies in the thread instead.
Can I use AI to write my post or generate images?
No. “No AI or MEME” removes both AI content and memes, so use your own photos and plain writing.
Can I share a link to my blog or guide?
Possibly. “No Low Effort Posts” removes posts with little to no effort, so if you link, add real context, your own results, and a genuine question.
Can I ask how to tell if a plant is male or female?
No. “No discussion about sexing plants” bans it, and the community points to the FAQ for that information.
