Can I promote my grow tool or seedbank here?
No. The rules ban selling, trading, asking for hookups, and self promotion, so a founder promoting a product will get removed.

Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.
Rule summary
- No selling, trading or asking for hookups: No selling, trading or asking for hookups
- No self promotion or flooding: This includes @ symbols. Any post or comment containing an @ symbol will be caught by Automod
- Please show respect to everyone and follow reddiquette: Please show respect to everyone and follow reddiquette
- Autoflowering related content only: Autoflowering related content only
- Memes & low-effort posts will be removed.: There are already plenty of cannabis / growing subs overrun with memes, they're off topic here. So are pictures of your cat or dog in front of your tent. So is your AI-generated art.
- No referral codes / links: Posts and comments with personal referral codes for seedbanks, Amazon, etc. are spam.
- Youtube posts must note why they are on topic: If you don't say why your video is relevant to autoflowers in the post title, the mods aren't going to watch it to find out why -- we'll just delete your post.
- No help requests with "blurple" light.: If you want help, post in-focus pictures with natural light. Intense purple-red light obscures many important details. Posts with blurple lighting may just get removed regardless (we want to make it clear they are unwelcome), and if the OP keeps reposting them they may be banned.
- Posts asking about yield are discouraged and may be removed.: It is difficult to meaningfully estimate yield, particularly well before harvest. Factors such as nutrients, light, medium, training, and watering all play a role in expected yield. Every grow is different. Therefore we often remove these kind of posts. If you want to get a rough sense what grows can yield look at [growdiaries](https://growdiaries.com/), particularly grows whose setup is similar to yours.
Works well
- A detailed writeup of your own autoflower grow, with in-focus pictures taken in natural light
- A troubleshooting answer in the comments of someone's help post, based on your own growing experience
- A question about nutrients, light, medium, training, or watering that invites growers to share their setup
- A Youtube video with a title that clearly explains why it is relevant to autoflowers
- A harvest recap that walks through what you did and what you learned, without linking anything
Avoid
- Any post or comment with an @ symbol, because Automod catches it and rule “No self promotion or flooding” applies
- Promoting your product, service, or grow content in any way, since “No self promotion or flooding” bans it outright
- Selling, trading, or asking for hookups, which “No selling, trading or asking for hookups” prohibits
- Dropping referral codes or links for seedbanks or Amazon, which “No referral codes / links” calls spam
- Posting memes, low-effort content, pet photos, or AI-generated art, which “Memes & low-effort posts will be removed.” covers
- Posting anything not about autoflowering cannabis, because “Autoflowering related content only” filters the topic strictly
What r/Autoflowers Is For
This community is for the cultivation of autoflowering cannabis. The people here are growers. They post about their plants, their setups, and their harvests, and they help each other troubleshoot problems from seed to harvest. The rules make it clear this is a working grower community, not a hangout space. There is a line in the low-effort rule that says plenty of cannabis and growing subs are already overrun with memes, and the mods here want to keep this one focused. So you get real questions about real grows, pictures of plants under proper lighting, and detailed discussions about nutrients, light, medium, training, and watering. If you are a founder, the honest framing is this: you are a guest in a hobby community, and the only way in is to care about growing as much as they do.
Rules That Matter Before Posting
The rule that decides everything for a marketer is “No self promotion or flooding”, because it bans self promotion outright, and the rule text warns that any post or comment containing an @ symbol gets caught by Automod. “No selling, trading or asking for hookups” closes the commercial door completely. “No referral codes / links” makes personal referral codes for seedbanks, Amazon, and similar things spam. “Youtube posts must note why they are on topic” is the one conditional path for links, and it only works if your title explains the autoflower connection before the mods read it. “Autoflowering related content only” keeps the topic tight, so off-topic posts do not survive. “Memes & low-effort posts will be removed.” sets a quality bar, and it explicitly rules out AI-generated art. “No help requests with “blurple” light.” matters if your post includes pictures, because purple-red lighting hides detail and repeat offenders can be banned. “Please show respect to everyone and follow reddiquette” is the baseline for how you talk to people.
What To Post
The safest useful post here is a genuine contribution to a grow conversation. Share your own experience growing autoflowers, answer someone's troubleshooting question with what worked for you, or post pictures of your own plants in natural light with clear focus. If you have made something useful for growers, do not pitch it. Talk about the growing problem it solves, in your own words, as a grower, and let people ask you questions in the comments. If you link a Youtube video, write a title that says exactly why it matters to autoflower growers, because that is the rule. Keep every post on topic, keep it substantive, and skip anything that looks like marketing, because this community has closed every commercial door on purpose.
What To Avoid
Do not promote anything. Do not sell, trade, or ask for hookups. Do not drop referral codes or links for seedbanks or Amazon, because the rules call that spam. Do not use the @ symbol anywhere in a post or comment, because Automod catches it. Do not post memes, low-effort content, pictures of your cat or dog in front of your tent, or AI-generated art. Do not post anything that is not about autoflowering cannabis. Do not post a Youtube video without saying in the title why it is relevant to autoflowers, because the mods will delete it rather than watch it to find out. Do not post help requests with blurple light, because intense purple-red light hides important details, and reposting blurple pictures can get you banned. Do not ask about yield, because those posts are discouraged and often removed. And always show respect and follow reddiquette.

Common questions about r/Autoflowers
Can I share a Youtube video about growing?
Yes, but only if the title explains why the video is relevant to autoflowers, and only if the video itself is autoflowering related content.
Can I include my referral code for a seedbank?
No. Rule “No referral codes / links” treats personal referral codes as spam, so leave them out entirely.
Can I use AI-generated images in my post?
No. The rules ban AI-generated art under the low-effort rule, and AI content is treated as banned here.
Can I post photos of my grow under my purple LED light?
No. Rule “No help requests with “blurple” light.” requires in-focus pictures in natural light, and repeat blurple posts can get you banned.
