Discussion in 'Vertical Growing' started by Chip Green, Sep 24, 2017.
Thanks for the information jon.
And some are marked V for vertical operation only.
Certain MH and CMH/CDM style HID lamps either won't work in the wrong orientation or will suffer severely shortened lifespan.
I've never seen an HPS lamp that wasn't a universal mount, so a vertically mounted DE should work fine.
But LED lighting is a better choice for vertical growing for lots of reasons.
So. Here's the "high school grade" Nugbox. I've got enough room to do eight (6L?) Buckets. 6 looks a little better. But 3 has the most even spacings. -edit- they're 12L buckets. I tested their capacity with an empty 3L milk container.
They are called "base up" not vertical.
Specifically mentions not to mount vertically.
And as usual your opinion about Led is inappropriate here.
And as usual you're answers are incorrect and unsupported.
Damn MM, I am really conflicted here, as much as I enjoy seeing him proven wrong,it's not true in this case. lol Easy mistake to make, the warning was against trying to install vertically. Its good news for anyone wanting to try vertical de's.

Oh well, you'll get him next time!
So who makes a vertical designated DE CMH bulb ?
Growershouse makes a DE cmh, you would have to email them to find out if its universal mount.
Not true. V is for vertical base up or down, it's in the codes if you care to read them.
LED is the better solution for vertical gardening. But you're welcome to keep living in the dark ages.
I just read the light manufacturer's own white papers. What do I know?
I have been in contact with a firm in China, about positioning of their DE bulbs, and this is what they emailed me back today …
Thanks your kind reply
about our 630w double ended cmh bulb , When using our CMH 630W Double ended bulb, be sure to use "horizontal" installation; can not be "vertical" installed, otherwise it is easy to damage the bulb
our 630w DE bulbs are better to position by horizontally,it can help to protect the bulb very well
Looking forward your reply soon
Yeh, they probably make the Growerhouse bulbs.
He did print an assumption as "educated" fact but I did only look up a couple of bulbs.
What bulb are those stats for and where did you copy it from please?
I am asking because I searched out light manufacturer info rather than re printed from a retail site for example.
If I am wrong I am wrong. I will apologize. But now I want to know why?
Growers house and HTG both have printed pretty bad mis-information like offering open hoods with single jacketed cmh bulbs.
Philips Lighting White Papers. Search by lamp. It's a great resource.
Maybe post one? I looked before I posted. The code is BU
Haven't seen base down or V.
But if I'm wrong I stand corrected. About the orientation of DE bulbs too if Hortilux is printing warnings for no reason.
Sorry. But learn to post proof before you speak with authority. You have been quite incorrect in the past. And never post any proof. And that is the main problem with Grow sites.
See previous response.
Never heard the term white papers before. Can I see one?
And there is nothing better with hanging your plants against the wall and needing a whole wall of lights to actually cover them.
I could buy another house here with your build and operating costs.
But you show no greater output per square foot than an average Grow. And poor quality.
As Popeye used to say "Gee, this is embarraskin! Whip yer apologies out Matey!"
It is from the manufacturer, the same link you posted, but you have to select wattage to see the specs.
This is the direct link.
From now on, do your own homework.
Huh. My phone shows no link or button where it says select wattages.
So is it universal and fine or is it recommended to be horizontal? They say both.
But like I said. I am wrong if it is universal mount. Sorry. I should have researched further.
I got a question now though. Know if universal mount means open or closed reflector instead of what we are arguing about that I shouldn't have started? Lol
