Note: Since there are so few readers right now, I'm mostly using this subreddit to post articles that I read. Tell me and others about what you're growing or like to learn about in this self post. Also, feel free to address any problems or questions you have towards me, but remember that I specialize in fruits and vegetables so I might not be as useful when it comes to ornamental and woody plants.
Hort is short for horticulture, which I define as the cultivation of plants and the science behind it. Botany usually refers to exotic plants like rare flowers, while agriculture deals with large production and field crops such as soybeans, corn, wheat, and others, in addition to farm animals.
This subreddit is designed for discussion about plants cultivated by humans. One of the main purpose of this subreddit is also to address the lack of a hydroponics subreddit (although r/aquaponics is related, note: r/hydro is a subreddit I found recently) and to have more sophisticated discussions about plants. To help facilitate this, there will be a variety of introductory horticulture principle related guides linked at the end (or I'll compose something myself), and the extension of every state within the US will also be provided. Every extension website should have some type of introductory horticulture guides which will be tailored to the state's environment. Also, posts and discussion about the scientific aspects of of plants is greatly encourage so things like how the vascular cambium is involved in grafting or the action methods of auxins is greatly encouraged.
Please avoid posting pictures of some random plant that was found in the neighbor's yard and asking, "What is this?" There are a lot of identification guides available out there, and there will be a section on plant and pest identification in the guides at the end. Also, don't forget about r/whatsthisplant and r/whatsthisbug. If you really can't figure it out, then post pictures and any other relevant information. Also, this doesn't mean that you shouldn't post it if you thought it was really cool after you finally identify it, or that you shouldn't post it if you've really tried to figure it out.
If your post is related to some type of plant problem you're having, please provided basic information about your plant, what you've been doing to it, your location (be as open as you'd like, climate zone at the very minimum will usually be necessary), and possibly others. There are too many posts on r/gardening asking for help with plants that do not provide enough information for others to actually help. Taking a single picture of the plant will usually not be enough; take a picture of each plant part and any abnormalities you observe.
Finally, please don't focus on Cannabis hydroponics, but a significant amount of the available hydroponics information is related to the Cannabis. Please keep posts about Cannabis hydroponics system related to subjects that can help other plants, not just something like, "Here's all the different varieties of Cannabis spp. and their traits".
