a lil off topic but, what about 10000k lights and cannabis? will a 10000k power compact 40 w floro do anything at all for the plant? do they put out any kind of uv?

im not sure what the 10000k part means, every one i looked at has a kelvin of 6700k or 7100k on google

10000k is a very deep blue aquairum light for coral and shit. it has to have some effect on cannabis im guessin. i aint no scientest, but my fathers a chemist. lmao.

10,000k is just over doin it. i am not saying it wont work, i am just saying that the sun is not THAT blue, so it probably wont benifit weed too much.

overdoing it? i dont think so. the sun is that blue. seeing how coral grows underwater because 10000k light penetrates thru the water from the sun in the ocean. the sun puts out all spectrums, so why wouldnt we try to recreate that as best as we can indoor to get very fine results. from what i hear/know, outdoor tree is way better then indoor when it comes to taste and i think potnecy. kinda like the whole uvb thing and pot. uvb can increase potency by what 25%, the sun puts out uvb, but most of the lights used for growing doesnt put out uvb. why wouldnt we try to recreate the sun as best as we can. i bet indoor would be 10 times better, then it is now.

u havent been here that long (neither have i) but bak to the sub. ive seen ppl use 65k for flowering and they say u get tighter buds but they also said they didnt yield too much

let me rephrase that one......
10,000k wont do good by itself . and of course u are right about having the whole spectrum including uv would be better for plants.
what i am saying is that the sun dont stay at any one kelvin temp all day. 6500k is kinda the "average" k temp of daytime sun. now in the early mornings and late afternoon the kelvin is alot lower. kelvin and plant light (lux , par, lumans, ect..) are a very complicated subject. (which i am not qualified to explain in detail)
a 10,000k bulb is very blue and very good for making a fish tank "stand out" same with the 20,000k bulb , but mostly they are just a supplement to the 6500k bulbs which are a little better for plants then a 10,000 but way better then a 20,000.
all these light temps, ect... are fairly new to the majority of the "growing world"
so we know ALOT about lights, but dont know how to properly add everything up to "useable plant light, per/plant, per/genetics, ect.." so it is just easier to make just a few different k temps of bulbs to grow with. (i can answer a few questions but i cant go any further with detail on this subject , it will take pages)

as for outdoor doing better then indoor , that is almost untrue. i guess if mother nature had a perfect year for plants , then some outdoor plants might be better then some indoor plants.
Outside is completely up to nature , water, food, genetics, ect.. (outside does have a few things to offer plant that the inside does not)
Inside is completely up to your environment ,YOU, water, food, genetics, ect... (also inside has a few things to offer plants that the outside does not)

now if your lookin for that better taste then i would say you want to grow in dirt, it dont matter if it is inside or out.
but on the other hand , i can grow in dirt and get a fire taste but the next man can take my same genetics and grow in hydro and it will blow mine away in taste...

Outdoor vs. Indoor all depends on who is doing the growing not as much as where its grown at.


you are just like me though..... and that is good , u are willing to learn . just like the uv subject .... i am currently trying that on a couple. and constantly reading on the subject. 25% is a awful high goal to shoot for but why not try ..eh?

i have done 6500k for flower and i got a very good yield (more then once) but it didnt seem
like the buds were as tight ?
its just a matter of getting what is right for your strain. some strains like less light , others like as much as u can give um. same with food .

The proof is the science not the bulbs. Look at the way plants grow veg state and using the 6500 is cool white signaling the start of summer and the warm red spec the 2700 signal the end of summer. So there ya go
