are the red and blue spectrums the only ones used by plants? and are they specific spectrums or swoops of them? ie...infrared and ultraviolet
thanks

plants use more than red and blue but they are the main ones.

uv ive been hearing lately increases trichome production toard the end of flowering

i see, but do you think that there are specific light waves that are not acknowledged by plants at all, the reason i'm asking this is because i was thinking that since with indoor growing you can control near the complete enviroment of the plant, is it possible that some of our visible light inhibits growth, which could very well be true. then if thats the case could we have a way of using only those spectrums? ie...uv light is helping thc formation.

thanks

some ppl say they dnt absorbe green light and you can use green light too look in on them during the 12 hr of dark but i wouldnt risk it, i dnt think any visible light would inhibit growth just infared light\the heat comming off your hps burning your plant up if your lights too close

i don't see why certain light wouldn't inhibit plants, there are many organisms that are killed by UV light. i am not saying that a wave of light is going to kill a plant but who's to say it isn't being inhibited by a certain wave...ie you said that infrared(heat) is bad in excess, and honestly on a broader case of other things heat is bad so we try to limit infrared(heat) so why wouldn't it be the case with other waves of light?
thanks

on a more basic sense, we know that theres the right mix of K P and N for its nutrient needs, same with we know there are specific lighting hours, ie 12/12, 18/6, 24/0, and 14/10. saying that i would say the odds are on the upside that there is a certain mixture of light waves that is an absolute ideal for plant life
thanks

Okay basically infared is bad because it induces the plant to stretch like a bitch ( heat ) as you said.UV is good because trichomes use it well u know what... Ill let this chap do the explaining :D says it all mate. How the plants use it? Why they use it? Why it the best weed is produced in high areas with uv?

peace

i'm drawing a conclusion to my own question that there is an ideal ratio, i keep thinking of already proven examples, to add to my list..we know they like a certain ph level, also a certain co2 level, we're finding out that molasses gives them needed carbs, they have an ideal temperature and humidity, umm someone help me out and add to the list
thanks
