This community is for cannabis growers of all experience levels, from beginners to people with years of cultivation behind them. People come here to share tips, ask questions, and show off their growing journey from seed to harvest. Topics include strains, nutrients, lighting setups, low-stress training, and troubleshooting plant issues. The rules make clear that every post must be directly related to cannabis and include cannabis images, so this is not a general gardening space. It is a cannabis-only network where members support each other and keep discussions civil and constructive.
The rule named No Promotions/Advertising is the one that will decide whether your post survives if you have any marketing intent at all. It says advertising and self-promotion are not allowed, no affiliate links, and no referrals, with direct links to relevant information only. The rule named NO Giveaways is equally important because it carries an immediate and permanent ban for a first offense unless a moderator pre-approves your giveaway. The rule named No Trading or Selling will get you permanently banned if you try to offer or supply anything, including testers, gear, seeds, tools, or equipment. The rule named Strictly Cannabis Posts means anything off-topic gets removed, and repeat behavior leads to a permanent ban. The rule named No Blurple Light Pics!! means posts promoting blue and purple grow lights may be removed. The rule named Be Respectful covers the basics, and violations can lead to warnings and eventually a ban.
If you are a founder doing respectful Reddit marketing, your only real path here is to be a genuine participant first and a founder second. That means sharing useful, cannabis-specific knowledge with no promotional angle attached. You could write a detailed post about a growing technique, a lighting setup using full-spectrum lights, or a troubleshooting guide for a common cannabis cultivation problem. If you link to anything, it must be a direct link to relevant information only, with no affiliate code, no referral parameter, and no landing page that sells something. Your post must include cannabis images or be clearly tied to cannabis growing. Think of this community as a place to earn trust by giving away real knowledge, not by pushing a product.
Avoid any form of self-promotion or advertising, including affiliate links and referrals, because the rule named No Promotions/Advertising bans them outright. Do not post giveaways or links to giveaways without explicit moderator approval, since the rule named NO Giveaways says an unapproved giveaway results in an immediate and permanent ban even for a first offense. Do not attempt to buy, sell, trade, or offer any goods, including seeds, gear, testers, tools, or equipment, because the rule named No Trading or Selling carries a permanent ban. Do not post pictures or discussions that promote blurple, meaning blue and purple, grow lights, because the rule named No Blurple Light Pics!! says those posts may be removed. Do not post anything that is not directly about cannabis, because the rule named Strictly Cannabis Posts says off-topic posts will be removed and repeat behavior leads to a permanent ban. Do not insult, harass, or discriminate against anyone, because the rule named Be Respectful says violations result in warnings and repeated offenses may lead to a ban.
