I'll have some wine and chill.

When you post statements that are incorrect, expect to be corrected, it's happened to me.I do think that KK's original comments were a bit snide. While I understand that's its frustrating to see misinformation spread by newbies, and I myself have often come across as snide or rude, I believe that its best to just give the information when this occurs, no extra commentary, like "haha". I'm not trying to attack KK for pointing this out, but I've noticed there is some eltitism and "posh" language/attitude that people pick up as they become better known in the CP community and as more people look up to them. I have seen this attitude in myself sometimes, and while I am usually blunt with info (I just try to leave corrections at "no" or "this is incorrect"), I have been working to try to be friendlier to people who are still learning, but without necessarily sugar coating everything (such as telling people "who knows? Maybe your conditions will work for you!", it is better to know someone that, while there may be a chance of success, there is a high likelyhood of failure, than letting them spend a bunch of money on a plant they will kill).
I've read about and researched an obsessive amount on CPs daily for a year and am still a complete noob. Get off of the defensive and you'll learn a lot more.
Smooter80 wrote:Peak photosynthesis(Chlorophyll absorption) occurs in blue and red. From my understanding, photosynthesis happens across the entire visible light spectrums. It may be less efficient in yellow, orange and green but it does occur. There is some debate on the subject and I'm not a photosynthesis expert either. LolYep that is correct that peak absorption happens in red wavelengths but the the leaves still absorb 80-90% of green light, generally. Apparently how it works is that green light can actually penetrate deeper into the leaf and the small amount of green light reflectivity helps the green light reach more chloroplasts inside the leaf. So once the surface-layer of chloroplasts is saturated, red and blue light don't do you much good and only green light can provide further benefit to the plant. Of course you need pretty intense light to get to this point and most of us probably aren't using lights that bright for our plants, but green light still benefits the plant at lower intensity.
Like you said, if you're using direct sunlight, you won't have to worry about artificial lighting.

Frankly I can't recall the original topic and I am too tired to look [WINKING FACE].The OP was originally asking if he could use a regular light bulb to supplement light for his sundew during winter, since natural light is a bit lacking. Lots of people do that, especially for small collections, and it certainly works.

They can be found in North America, Canada, Central American, South America, Africa, Europe, Asia, the Philippines, and Australia + New Zealand.
