Posting links
No links to any competing commercial websites.
You can post links to Amazon as they are our affiliate partners.
You can post educational links and youtube links as long as there is no commercial branding, merchandise or links to merchandise offered on the page. If you go to a page at another cannabis website and anything is for sale, a banner to a seed bank, or anywhere that sells grow supplies; You cannot post that link. Links that show tools or supplies that can help member and are not available on Amazon or other approved vendor will be considered on a case by case basis. The ownership of ILGM fully supports helping all growers.
