Can I promote my product or brand here?
No. The rules ban selling, trading, asking for hookups, and all self promotion. You need to earn trust by contributing genuine autoflowering cultivation knowledge instead.

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 grow journal post showing your autoflower plants week by week with clear natural-light photos and notes on nutrients, medium, and training.
- A text post explaining a specific autoflower cultivation technique you tried, what happened, and what you learned from it.
- A YouTube video about autoflower growing where the post title itself states why the video is relevant to autoflowers.
- A help response to another grower that draws on your own autoflower experience and stays focused on the plant problem at hand.
Avoid
- Do not include any @ symbol in your post or comment because Automod will catch it automatically.
- Do not post referral codes or links for seedbanks, Amazon, or anything else because the mods treat them as spam.
- Do not post memes, pictures of pets in front of your tent, or AI-generated art because the mods remove all of that.
- Do not post a YouTube video without explaining in the title why it is relevant to autoflowers because the mods will delete it without watching it.
- Do not post help request photos taken under blurple light because those posts may be removed and repeated posting may lead to a ban.
- Do not ask people to estimate your yield because those posts are discouraged and often removed.
What r/Autoflowers Is For
This community is for people who cultivate autoflowering cannabis. The public description says it plainly. The rules reinforce that everything posted must be autoflowering related content only. People come here to discuss growing techniques, share their progress, and ask for help with their plants. The mods work hard to keep the focus tight, removing memes, low-effort posts, and anything that drifts from the topic of autoflower cultivation.
Rules That Matter Before Posting
The rule called 'No self promotion or flooding' is the one that will shape your entire approach here. It bans self promotion outright and even catches any post or comment containing an @ symbol through Automod. The rule 'No referral codes / links' closes another door by treating referral links for seedbanks, Amazon, and similar sites as spam. If you want to share a video, the rule 'Youtube posts must note why they are on topic' requires you to explain the relevance in the post title itself. The rule 'Autoflowering related content only' means anything off topic gets removed. The rule 'Memes & low-effort posts will be removed.' keeps the bar high, and it specifically calls out AI-generated art as off topic.
What To Post
A good post here is genuinely about autoflowering cannabis cultivation and nothing else. If you have real knowledge about growing autoflowers, share it in a way that helps people. A useful grow update with clear photos taken under natural light could work. A detailed explanation of a technique you tried with your autoflower plants could fit. If you make a YouTube video about autoflower growing, you must say in the post title why it is relevant to autoflowers. Keep your post focused, practical, and free of any promotional angle. The community wants substance, not marketing.
What To Avoid
Avoid anything that looks like selling, trading, or asking for hookups because the first rule bans all of it. Avoid self promotion entirely, including any use of the @ symbol, which Automod catches automatically. Avoid referral codes and links of any kind because the mods treat them as spam. Avoid memes, low-effort posts, pet photos in front of tents, and AI-generated art because all of those get removed. Avoid posting YouTube videos without explaining their relevance in the title because the mods will delete them without watching. Avoid posting help request photos taken under blurple light because those posts may be removed and repeated reposting may get you banned. Avoid asking people to estimate your yield because those posts are discouraged and often removed.

Common questions about r/Autoflowers
Can I share my YouTube video about autoflower growing?
Only if you say in the post title why the video is relevant to autoflowers. The mods will not watch the video to find out, so the title itself must make the connection clear.
Can I include a referral link to a seedbank I recommend?
No. The rules say posts and comments with personal referral codes for seedbanks, Amazon, and similar sites are spam and will be removed.
Can I mention my Instagram handle or social media account?
No. The automod catches any post or comment containing an @ symbol, so avoid it entirely.
What kind of photos should I include when asking for grow help?
Take clear, in-focus photos under natural light. The mods remove blurple-lit help posts and may ban users who keep reposting them.
