Can I post a discount code?
No, the rules ban advertising, affiliate links, and referrals, so a discount code will not survive here.

Rule summary
- Be Respectful: Treat all members with respect. Disrespectful behavior, including insults, harassment, or discrimination, will not be tolerated. This community is a space for cannabis growers to share knowledge, ask questions, and support each other. Healthy debates are welcome, but keep them civil and constructive. Violations of this rule will result in warnings, and repeated offenses may lead to a ban. Let’s maintain a positive, supportive environment for all members.
- No Trading or Selling: Any attempt to buy, sell, trade, or offer/supply (whether legal or illegal) — including but not limited to testers, gear, seeds, tools, and equipment — will result in a permanent ban. This type of solicitation violates Reddit's terms of service and is classified as prohibited transactions for illegal goods.
- No Blurple Light Pics!!: Blurple (blue and purple) grow lights are not recommended for serious cannabis cultivation discussions. They often provide poor results and make it difficult to assess plant health accurately. Posts or discussions promoting blurple lights may be removed to maintain the quality of advice shared in the community. Please focus on sharing information about full-spectrum, high-quality lighting options for optimal growth and plant care.
- NO Giveaways: Giveaways or links to giveaways are not allowed unless explicitly pre-approved by the moderation team. Any attempt to post, promote, or share giveaways or links without prior approval will result in an immediate and permanent ban, even for a first-time offense. This rule is strictly enforced to maintain the integrity of the community. Contact a moderator before attempting to share any giveaways to avoid penalties or permanent bans.
- No Promotions/Advertising: Advertising and self-promotion are not allowed. No affiliate links! No referrals! Direct links to relevant information only.
- Strictly Cannabis Posts: We have cleared some posts that did not include cannabis images! Please respect this community as a cannabis network and only post cannabis images and posts related to cannabis. Any posts that are not cannabis related will be removed, repeat behavior will lead to a permanent ban.
Works well
- A grow journal with clear photos of your cannabis plants and honest notes on what worked and what failed
- A troubleshooting post showing a sick plant and asking the community what is wrong
- A question about nutrients, lighting setups, or low stress training that invites growers to share their approach
- A harvest recap sharing what you learned from seed to finish
- A direct link to relevant information that genuinely answers a question being discussed, with no affiliate tags or referrals
Avoid
- Posting an affiliate link or a referral link, both are banned outright
- Announcing your grow gear product or app as a post, that is self-promotion
- Offering seeds, testers, tools, or equipment in any buy, sell, trade, or supply form, that earns a permanent ban
- Sharing a giveaway or giveaway link without contacting a moderator first, that is an immediate permanent ban
- Photos taken under blue and purple grow lights, those posts get removed
- Images or topics unrelated to cannabis, repeat behavior leads to a permanent ban
What r/HerbGrow Is For
r/HerbGrow is a community for cannabis growers of every experience level. People come here to share tips, ask questions, and show off their growing journey from seed to harvest. The topics cover strains, nutrients, lighting setups, low stress training, and troubleshooting plant problems. The welcome message says it plainly, this is a place to share knowledge and support each other, so the room is full of growers talking to other growers.
Rules That Matter Before Posting
The big one for anyone with a product or a link is “No Promotions/Advertising”, which bans advertising, self-promotion, affiliate links, and referrals, and only allows direct links to relevant information. “No Trading or Selling” is even harsher, because any attempt to buy, sell, trade, or supply things like gear, seeds, tools, or equipment earns a permanent ban. “NO Giveaways” means you cannot post or share a giveaway without asking the moderation team first, and skipping that step is an immediate and permanent ban even for a first offense. “No Blurple Light Pics!!” gets posts removed if they promote blue and purple grow lights. “Strictly Cannabis Posts” requires that your images and posts relate to cannabis, and repeat off-topic posts lead to a permanent ban. Finally, “Be Respectful” sets the tone, and repeated rude behavior can get you banned.
What To Post
A good post here looks like a grower helping growers. Share your own cannabis grow with clear photos taken under proper lighting, ask a real question about nutrients or training, or write up a problem you hit and how you worked through it. If you link to anything, it must be a direct link to relevant information, with no affiliate tags and no referral code. If your product happens to help growers, the safe move is to join the conversation, answer questions honestly, and let people ask you, rather than pushing your thing in a post.
What To Avoid
Do not advertise or self-promote, and never drop affiliate links or referral links. Do not offer to sell, buy, trade, or supply anything, including testers, gear, seeds, tools, or equipment, because that is a permanent ban. Do not post or share a giveaway without contacting a moderator first. Do not post photos shot under blue and purple grow lights, since the community says they hide plant health problems and those posts get removed. Do not post images or topics that have nothing to do with cannabis. And keep it civil, because insults and harassment are not tolerated here.
