Your Grandpa's Weed or is UV supplementation really needed?

The temps got a little low for a week and had a negative effect on my babies.They slowed down, a lot.
Have since made corrections, but it happened.
The corrections were to mostly stop venting the tent and let it keep its own heat and that has worked.(there is some smell leaking out though)

This is today, almost 5 weeks into 12/12...
Like I said, a bit behind.
So i got my bulb and i and my plants are loving it so far... new light 1.jpg

I just recently came across the realization that my old 400 watt MH bulb/fixture/ballast combo is a real UV emitter! I'm using my Timber CXB 400R, but I don't think it puts out much UV light.....SOOOOoooo I think I'm going to switch out the COB for the MH for the last week of flower to try and enhance/ripen that last bit of "stuff" in the plant with that excessive UV. I've heard that finishing the plants with MH light is a fairly common practice, actually....I've got the stuff...brand new bulb....What the heck?....right?

Also, the price on the 400 watt bulbs has gone waaaaay down since back in the 80s when I first started using them! I got one for around $20...on Amazon no less! Too easy to not give it a shot! :)
at one point in time i bought a cheap 14k metal halide bulb from amazon. like the actinic bulbs rm3 & illumination used to use

My bulb is a Sylvania/Osram Metalarc MS400HOR -says it's 4200K. Sounds like yours was a LOT bluer than mine!

it was a violet like color, cheapie chinese bulb for aquariums. wish i had a meter to get it tested to see the scientific output of it. it did make the girls frosty though...image.jpg i love these pure uv though, wish i could find the originals somewhere...

i also ran a cheapie 5500k aquarium bulb for veg... i figured with them originally being for aquariums, they would have even less protective coating to block the uv they emitted...

i currently have those, but they produced one that was all uvb, no uva at all, people really fried shit with, plus they figured out that uva is also beneficial
For uvb I just use spiral style reptile bulbs

http://m.petco.com/shop/en/petcostore/product/reptile/reptile-habitat-hoods-and-lighting/exo-terra-reptile-uvb150-bulb#i use one of these in an overhead fixture in my garage, I'm gonna move it into my flower room when it's time


It's only 26 watt so I leave it on for the full 12 hrs, nothing bad yet

The UV emitted from that bulb is only effective 18 inch's from the bulb!
I keep it on a dangler, thinking about maybe mounting new ones, verticles in the end corners of the new space now that I'm in here foaming the walls. Thoughts?1484500207038999148185.jpg Capture+_2017-01-15-12-12-09.pnglike where the red is, or centered where the hps would be? (Separate timers of course)

i used the 150's & kept them inches away, worked well, but compared to the pure uv's, you might want to switch due to them being almost equal in cost with more power.

I know several that hang the damn things all over a plant. I mean I get it for a small grow or small plants...Average 6' plants so they're not the best idea for me.....

I'd bet a single Agro 2'er would be all you would need in there! Might as well go with top-o-the line stuff! 1 is easier to deal with too.
I'd say a 400 MV but their getting expensive and harder to find. They are being replaced with "MultiVapor" bulbs......FAH!

great point @Dr. Who ,would you really prefer the mv? i kinda wouldnt want to cool it & the space it would take up with a hood if i was not using it vertically ? but it is a great addition though

When running HPS only in my 5X5, I also run five lizard lights -- one in each corner plus one dangling. They are on the entire time HID lights are on. Never had a problem as long as plants don't get too close. (12" minimum).
I recently reconfigured my lighting due to cold temps. Now I run 400w MH - 600w HPS - 400w MH. Since they are "bare bulb", I've switched off the lizard lights for now. I'll probably leave them off unless I switch back to HPS only.
Too much UV is a bad thing. Based on personal experience, I am convinced that sunburned leaves are much more vulnerable to PM infection.

Nope. You'd be that guy.

soon as I get some room maybe just in the winter.....

I think they do a 10kw too 6000k

1.High pressure short arc xenon lamp is also called the ultrahigh pressure short arc xenon lamp (work pressure in the 10 atmosphere above).



2.short arc xenon lamp (arc length in several millimeters), spherical xenon lamp (shell is spherical), referred to as the xenon lamp.



3.The lamp is a kind of high brightness of point light source, color temperature for 6000 k or so, light color close to the sun, is the gas discharge lamp in color rendering one of the best light source,.



4.suitable for film screening, searchlighting , train driving and simulated sunlight, etc.

I was thinking I might be jammy and hard start it and pop it down to 3kw see if I can get 1200 hours+ out of it but I`m not sure if its run time or starting up that kills a xenon ?




Ok now even a 200w one looks fun to play with
