Are people using this in veg, what unit are you using if so?. Read it's not safe due to uv.

What are the health risks?, say 315W if you turn it off when in the room surely it's little to no risk then?.

Think of it like a weak tanning bed.... you can spend 15mins in there and not have any problems...

Dont harvest your plants under it, you dont wanna sit there for 4+hrs.... will piss off your skin/eyes....

Don't stare at it, but thats a given... don't stare at any light source that you grow plants with.... Sun, HPS, MH, CMH, LED..... even CFL, if you are able to stare at it... it belongs on a night stand for reading a book..... lights that produce plants are painfully bright...

What type of hood/fitting did you buy/modify in order to hang it bare vert?.

They're called vertical socket cordsets, they're in both the Sunlight Supply and the Hydrofarm catalogs, versions vary somewhat based on plugs and such. They're very inexpensive because you aren't buying a reflector.

Any HID lamp will emit some UV. Most such lamps have glass that impedes UV transmission because most lamps are made for humans to see things by (duh, lol but it does need to be said! ).

Only COB LED has zero UV emissions, which I think is a good thing on balance; first, my ladies don't seem to suffer for its lack and second, one could supplement with UV and run it on a separate circuit; one that shuts off anytime people are in there.

Seems a lot of those fitting are US plug sockets ;/

Could you use this and cut the hood at the mounting?. The hood does not look like the right fitting though o0.

You can get them with mogul socket base in Hydrofarm, Sunlight Supply and regular 120V grounded for big CFL lamps.

Seems the shipping price etc works out almost the same price as just buying a horizontal hood local. If only for it's fitting.

Leading back to the other question. Are you able to take a standard horizontal hps/MH bulb, unscrew or cut off the cheap alum horizontal hood and then use the bulb vert?.

Similarly could you do it for this as well. http://www.ebay.co.uk/itm/Omega-315W-Daylight-Ceramic-Metal-Halide-Grow-Light-Kit-Hydroponics-/262384774152?hash=item3d1759ec08:g:NnAAAOSwv~xXDg6I

Yes but double check your lamp. Not all can stand being run vertically.

Ok will do, by lamp you mean only the bulb itself?, the hoods I've read up on have no warning of wrong orientation. Out of curiosity what is the outcome of verting a bulb not fit for it.

Hopefully my quote is pertinent to the topic, I run 2 bulbs 600w each hanging vert, hoodless , hps + mh spectrum along. An old school grower told me that as a tip for a set up and I don't see any thing wrong w that and I had to hang the bulbs w a vertical mogul socket w a 25 ft long cord so I could keep the ballasts out of the room and made sure to get vertical bulbs as well.
Does the combo w led + hids result in better yields ? IMG_2333.JPG
peace.

My plants responded better to the 315W CMH lights than they did to 600W HPS.
