10K Lighting ?

[JohnnySocko]

I've asked this before but perhaps I framed it wrong.....

all things being equal: I was wondering if there might be some advantage to using a bluer spectrum (like a "Radium" for Marine tanks) not only during veg but then also partially into flower (like maybe the 1st week or two past 12/12), esp. if height restrictions are in play....just thinking of ways to mitigate stretch vs. height restrictions after my Newb C99 disaster with a insane, uncontrollable stretch even under POINT BLANK 600W of HPS

...anyway; not sure if this post has any relevancy or not (I might be misunderstanding it) but found this in a debate over in nutrients

You would start losing intensity after 6 months..i dont care what you hear from all of these so called ganja gurus on here..This is what happens i know.Change your bulbs out every six months or so..third grow with them.Can you use them longer than 6 months..YEA..you can..will you start losing production..YEA..you will after6 months..If you lose even one ounce of production because your bulbs are weak and old you have lost money.If you lose 14 grams of production you have lost money.I have seen no noticeable difference between using expensive bulbs vs inexpensive bulbs as far as production or quality goes.The sun leaf bulbs made in china actually OK..They however are somewhat unreliable.And no..dont waste your money on a expensive light meter..It would cost around 500 to 600 dollars for a light meter that is good enough to tell you about what is going on with your bulbs..if you have any question about if your bulb is good or not..change it.
If you really really want to have the blue spectrum of the dual arc bulb just buy a zoo bulb with a nanometer spectrum of over ten and add the additional bulb to your grow room for the UVB rays.
But in order to have any effect upon the resin production of the plant you must run UVB in your veg room too from the studys ive read.The dual arc bulbs at the grow shop i go to are around 250 bucks a shot.A HPS bulb ranges between 60 bucks and 125 bucks for the ushio or the eye hortilux.In other words the money you pay for the dual arc you would be able to purchase not only the HPS bulb..but the zoo bulb and still have money left over..AND have UVB that are actually effective at doing something.

...and yeah, I "reasonably" versed with a understanding of bulbs, color temps, and spectral demands during different plant stages...just wondering if anyone has bothered experimenting beyond the proverbial switch from MH -->HPS/veg-->flower thing (basically restricting use of the lower color temps during the latter 2/3rds of flower)

10k 600w and 1000w for the last week or weeks are awesome. Been using them for a wile you can 100%tell a difference

full spectrum all the way thru harvest. I dont think it helped slow down my sativa though.
