Yeah I wear sunglasses so I can stare at them beautiful girls for much longer. Or, if my glasses are missing, I just put my hand to cover the hps light. I don't want to ruin my good eyesight.

What does the c in CMH stand for?

Are you really paranoid about this ? the sun is 1000 times stronger than any 1000 hps or mh do you ever go outside without sglasses my eyesight is better than 20/20 and ive been staring at them for 10 years chill out.

I' not sure it affects your distance vision (20/20, 18/20, etc), rather, it's my opinion that it affects your night vision more. Constant osure to high light intensity levels should lessen your retinas' sensitivity to visible light. If this is the case, then it would mean someone who has stared at 1000w lights up close or the sun for a period of time would have less effective night vision than someone who avoided those activities.
Conversely, someone who has been locked in a dark basement their whole life would have higher retinal sensitivity to light than someone who has lived a normal life and spent time outdoors (or staring at hps lights up close).
I'm not a scientist.......its obvious........but just trying to use logic here.

what people don't realize is that bright blue/purple light is an eye killer.
yes, there's a reason your eyes go 'oh no' when you look at a brilliant blue/white 6500k light source
the eye's defense mechanism for uv light is in the surface of the eye and is absorbed there - hence cataracts later one
but blue light makes it right through and causes very harmful photochemical changes inside your eyes - they eye's natural defense for this is lutien, a yellow pigment that is supposed to build up in the eye from the diet which is now lacking it
anyway, long story short - if you've got metal halides going (veg) wear rootbeer tinted uv400 quality sunglasses, and not cheap shit either, and NOT yellow, those cause your eyes to dilate and let more light in
if you have hps' going, wear dark grey uv400
never look directly at an hid element
i don't do either, my friends basement has shoplights & cfls everywhere so he just powers off he hids and turns those on and life is good
I guess I don't need to tell anyone how dangerous a cracked halide is, emitting UVC?

basil: nice info all around, but especially about the glasses.
good info here, i went from 400 to 1k it was a whole different story............
400w can even fuck you up but I can't even get close to lookin at that 1k.
I am gonna get some uv 400 shades for when i unzip the tent

you're welcome guys
by the way, those light boxes for seasonal depression are terrible for your eyes
yes, they help depression, but the blue/white at that intensity is not a good thing
extensive studies conducted by the US air force has proven that green light at about 550nm will have equally good results for seasonal depression without eye damage
its easy, in this case, just get uv400 green (not light green) tinted glasses and your blue/white light box is now ok, just dont stare at it directly
they make specific green lightboxes but stay away from him, he is a rip off
--------------------------------------
lutien is available in dark leafy greens, egg yolks and supplements and is important to protect the eyes from oxidative damage not just filtering blue light
--------------------------------------
another thing - the human sleep cycle is dependant on the brain producing melatonin, which causes a natural deep sleep with proper mental & physical regeneration
you should not expose yourself to bright full spectrum (or bright green) light after 8pm or you will not have a proper nights sleep
has anyone noticed being their flower room without sunglasses before bed and then not feeling quite asleep for half the night?
i have a red light in my bathroom for this reason, because i dont want to be blasted awake just to take a wiz
peace

keep up the good info!
eye saftey in grow rooms is something a lot of people overlook. I have a green bulb for my back yard i cut on when i blaze but its closer to 500nm more of a "dark green" hopefully the 50nm makes a difference.
I crashed out early in the day today around 5pm and it was 1:30 am when I woke up i knew i was gettin up early but damn not this early haha i think i may have screwed up my sleep schedule again....
I was looking at the spectrum chart you posted i was wondering has anyone experimented with anything lower than UV for growing pot? gamma rays? x rays? radio/radar/am waves? kind of out there but its a thought.

sorry to get off topic.... but hey
yes, people have experimented - by accident - when they had a cracked halide and the UVC damaged the plants and them as well
i'm sure crazy scientists have dosed plants & seeds with x rays; the end result might be out of 60,000 seedlings - 1 or 2 mutated plants that would make g13 look weak lol
the japanese disscovered in the 80's that the chrorophyll molecule/photon reaction takes (?from memory) about 1 50th of a second so if a light (led would be perfect for this) pulsed 50 times a second, but the 'on' flash was only 25% of the 50th of a second, you would not just save 4 times the power, but more because the other 75% of the light must be dealt with by the plant as heat waste to expel, which it would no longer have to do --this is why plants are green, they cannot use green light so they try to reflect it because it is just a heat burdon
many in the growing community have poisoned themselves & others messing with Colchichine (a poison more powerful than nerve gas ounce for ounce, and very carcinogenic extract from the russian crocus) which causes mutations and out of 300 poisoned seeds, a few may turn out to be super potent mutants
on the other end of the spectrum - invisible infrared is definately used by flowering plants in a way we do not fully understand, which hid's give a lot off anyway
and, if you have to go in your grow rom during dark phase, don't use those silly incandecent green lights; they appear green, but really still have lots of blue and red (photosythetically active) light coming through; so use a green led and try not to directly point it at the plants. the right leds have a very exact bandwidth. this clipmate from streamlight is only about $17 at resellers
a very low current of electricity running through the plant has shown to increase growth and production on food plants
a bit of aspirin in water (aspirin is just based on extract from the bark of white willow trees) causes a false alarm within the plant and it thinks its under attack by fungus or microbes so it beefs up its immune system, hence, it ends up being far more resistant to root rot and maybe (cant remember) bud rot too
thats all the mad science I can remember off the top of my head

you're absolutely fine there
I just meant really bright bluish white light or really bright green light after 8 pm
i hate those super blue white floros but the plants seem to feel differently

if you're farming with vertical lights especially and not wearing shades, you are killing your eyes. those white spots? yeah.

I always wear sunglasses or the pair of welding/cutting goggles I keep next to the door.

I went a couple weeks into my second grow without using eye protection but quickly discovered I needed glasses whenever i added a uv lamp. i started getting headaches and my eyes hurt often. I went out and bought a cheap pair of sunglasses with uv protection. These suckers are huge and are the kind of sunglasses older people wear outside of their prescription glasses. They protect all around your eyes and have great visibility. They were on sale for 50 cents. I also work outside all day so I appreciate protecting my eyes now. Never look directly at the light (no matter the wattage). Hell you're supposed to be looking at your plants anyways. Be safe and always protect your vision
On a side note, its a good idea to switch off all HID lamps when entering into a room. Have some cfl's dispersed throughout your room and use them while in the room. You shouldn't have to spend that much time in your rooms when you get everything dialed in.

lol valid point!
this. as long as you arent staring into the bulb it should be no different than being outside in the sun, you dont stare at the sun do you?
