If you have the time check this out https://www.coursera.org/learn/plantknows Or check out the book what a plant knows, you can find it free online, it's really fascinating and shows just how aware/alive plants really are

I'm not sure if you've heard of Coursera but I think it's such a great resource. Free online courses taught by university professors from all over the world. You have the option of purchasing a certificate for each course but even if you choose not to, you can still take the classes 100% no cost. I've taken maybe 4 courses with them. This course is taught by a professor from Tel Aviv University. It's one of the first courses I enrolled in on the site. I will admit though, I ended up unenrolling because the material was a bit difficult for me and I didn't have the time to dedicate to extra studying. I come from a foreign language background so science of any kind is like....well, a foreign language in its own sense lol. I do plan to enroll again in the future though! Hope this helps :)

You're having a weird thing happening to your plants. There is something weird about your environment, but you're insisting there's no connection between the weird thing you're doing and the weird thing that is happening.

Sigh. 99% of the time, the weird thing you're doing is causing the weird thing you're seeing with the plants. You don't need to understand any botany to do that basic sort of reasoning here. But for the record, here's the explanation of what you're seeing.

Ed Rosenthal's books talk about how you can grow cannabis under blue light. They will show sex but not fully go into flower. It's a good trick for sexing plants! I've never tried it, but it makes perfect sense from a biochemistry perspective.

Cryptochromes are proteins that are photosensitive to the blue-green part of the spectrum. They control the circadian rhythm (biological clock), in both plants and animals. (Which means that the circadian rhythm developed billions of years ago.

So it's not true that plants don't respond to green light. Chlorophyll A&B don't respond to green light. But there's a lot more to plants than chlorophyll.

Photoperiodism (when the plant goes into flower) is controlled by the ratio of red to far red. But if the plant's biological clock is getting screwed by constant blue/green light, that doesn't matter.

Here's a good course on botany that explains how photoperiodism (flowering cycle), phototropism (bending towards the light) and thigmotropism (growing in response to low stress training) all work. You can take it for free: https://www.coursera.org/learn/plantknows

But like I said at the top, just some basic reasoning is all that's required here. Stop giving the weird input, and the weird output will probably stop.

I just started learning, and have learned a lot from Wikipedia. (I'm not the best auditory learner)

Each session that I dedicate to learning, I just start with a different term (like, e.g., taxonomy, or flowering plants (Angiospermae), or Asteraceae) and then just read and click on whatever I dont know.

Wikipedia on desktop is nice because you can just hover your cursor over the word and it will give you at least a portion of the first paragraph of the article on the term. On mobile, you create folders to save and categorize articles. Like I've created the folders 'plant genus' and "plant families" so far.

Also, Coursera has some free beginner plant courses. I'm doing this one right now by Tel Aviv U and it has a lot of videos, as well as transcription of the videos.

I think the best place to start is to grow some plants that you're interested in. I use OneNote to jot down research info on things that I'm either growing or foraging but you could also start a physical notebook. It's fun to learn about the native range and habitat that your house plants are used to.

I took this course for some more detailed biological info on plants and how they interact with the world https://www.coursera.org/learn/plantknows

I like to keep an eye on this site https://phys.org/biology-news/ because it usually has info from new plant studies that are coming out and sometimes just fun info.

If you're into podcasts and blogs http://www.indefenseofplants.com/ is my favorite. Their blog posts are good little nuggets of knowledge. A few of the early podcasts can get a little dry but you can learn so much good information here in a way that's a lot easier to remember.

look into getting a tree identification book, they're always good to have for reference and then go for a hike, you can even walk around your neighborhood and practice identifying trees. Then you can go to /r/whatsthisplant/ if you get stuck on one or are unsure if you've found the right ID.

There are also more specialized subreddits depending on what you're interested in diving into.

/r/gardening/ is for personal yard gardens and questions discussion related to them

/r/marijuanaenthusiasts/ is for trees

/r/bryology/ is about moss

/r/Lichenology/ is about lichens

/r/savagegarden/ is about carnivorous plants

/r/foraging/ is good for helping to ID edible plants and mushrooms you find in the woods or to see what other people are getting from the woods

/r/houseplants/ is for indoor plants

I hope this is enough to get you pointed in a good direction. Maybe your area has a garden club you could join because I found just talking about plants is a great way to learn.

Does anybody want to take an online farming, social (or regular) entrepreneurship, or Android Development course with me?

Anybody interested in any of these? We could meet in a coffee shop or library and/or chat online.

They don't have nociceptors, so plants don't feel pain. I took a coursera course a while ago that was really interesting. It's being offered again, and I would recommend taking it if you have time. It can be taken for free.

I read an article on phys.org regarding beliefs. There's an idea called 'motivated reasoning' that people use when deciding whether or not to accept evidence, and a person's intelligence or ignorance doesn't always predict whether or not the evidence will be accepted. Political beliefs do.

In the end, we all have our reasons for becoming a vegetarian. It's not something I advertise but it comes up often when picking a restaurant or ordering food at work. Most haven't really cared unless they are too. My manager asked some questions and has been accommodating when he or the company orders food for us.
