Where to begin........

I dont know if you can run a de in vert unless you jerry rig a fixture(but i havent looked)

But they nomally throw a rectangluar pattern

Would be bout perfet for a 4x6

And if you have issues like me then you stretch her over a 7.5x7.5 to see what happens lol

I would imagine that the bracket would still cause a shadow of some sort too

They are doing something wrong.

I spoke with several people about the idea. One problem is the frame, that could be fixed with a skinny metal piece, think of the frame of a micrometer.

The bigger problem is that in order to work properly, the DE lamp must operate at about 650F, or performance, efficiency and spectrum output all suffer. A bare DE wouldn't run hot enough, especially if there was a breeze.

I dont know about that



It really doesnt hold much heat but i could be wrong

Elsewhere in this section there's a discussion about a vertical DE fixture with built in cool tube. It's sexy but it's already obsolete.

Nice trip down memory lane here.

Everything you're doing or considering, I've done the same.

In my case I was extremely happy with my LED lights on vertical trellis panels.

If people aren't happy with the frost from LED lighting, consider adding a florescent UV lamp.

Don't recall saying anything about not being happy with the frost from LED lol......

Also if you're going to take an LED and add UV to it then what's the point put the HID/CMH back up and you don't need the "added" UV. This is where I don't get the arguments for LED. How can one say the spectrum is "complete" yet you're adding UV and Reds to your lighting setup. Guess what already has the reds and the UV.......

I'm not picking on you brother just discussing the topic.

We are going to find out soon lol

That cool tube setup did look sweet

Id copy the design

This is why i went with the gavita

Although i fully admitt to seeing great grows with leds.

But at the time (year or 2 ago)

I wasnt quite sold on the leds reading thing like needing to run high temps (i thought over 80 degrades terpines) to having mag deficiency just from using the lights

Plus the cost.....for 450 bucks my gavita is killing it for what im asking of her.


A comparable led seteup would cost arond 800 plus.
Thats the main reason i went with the gavita

I KNEW it would PRODUCE and i liked the price ...i also use the heat in the winter so dont have to pay for just heat...

There are SE lamps on the market that have a DE Arc tube in them...
Anyone who thinks that a DE has more output due to an SE having to pass it's current around the wire within the lamp should turn of the lights now and just pack it up.
It is about the "chemistry" in side the lamp, and the type of glass.
Plus as far as I know most all DE lamps have a specific Hz rating that they are supposed to operate at which is higher than most SE lamps.
And to top all that, Straight from the Hortilux reps - SE HPS has a better spectrum for use as a SOLE lamp source than a DE Hps.
Yes, less overall photons but better spectrum and we are taking about using these things in close proximity in the vertical section.
So, Screw in your economical SE lamp and grow some Dank!!!

My idea was since gavitas are meant for high ceilings if i could control the heat they would be more intense at shorter height.

• So now begins my great de/hps plus led

Experiment.


If i set up the room like in my head i will have my scrog side double stacked with led strips (this will mean i just increased my footage by around half )

Then in the other half ill run the gavita to make up for various strain heights in the seed running table.

Im hoping
That the light from the gavita will "spill" over to the led side there fore negating the need for uv lights (provided by gavita)

And HOPEFULLY this will mean a stanrdard nute solution and mabey i wont have to run at higher temps since the gavita will provide some i r light

What do you fellas think

In my head it seems like a good idea .....but dark and scary things live in my head lol

I could be very wrong cause i read way too much without retaining lol

But wasnt the gavita supposed to have a very full spectrum even though the light looks like hps?

It's just hps, unless of course you supplement with their plasma
The rumor is that the Hortilux DE lamp has a tad nicer spectrum and will run in Gavita's but not sure if they are doing a 750 yet

Nice yea i coulda swore reading something about it having more blue then hps

The other thing to consider here if your talking a single 600 per 4x4 is "vertical coverage"
For those who have used vertical 600's, how many inches of vertical canopy can Mobo ecpext to have good light coverage on without moving the lamp up and down with a mover etc?
As we see @zep_lover has his lamps double stacked

Click to expand...

i would say for premium light zone only 24 inches per bulb.that is why i used two stacked in each of my three cabinets.

No offense taken. 'People' in this case was just a placeholder for whomever might think there's inadequate frost. I'm not one of these people. I wasn't implying you were, either.

I have never added red or UV to LED and I've always been happy with the results.

Adding UV to LED does make sense for extra resin production. It is also true that very few HID lamps emit enough UV to make any different, because they're specifically made to shield it so as to avoid damaging the eyes and skin of people working under them.

People have shown that additional UV light increases potency when it's used judiciously.

If I had the ceiling height I'd be running the gavita 600/750 fixtures no questions asked .Especially like the controllers they have now for them . And for under $400 for the fixture in most places including the bulb you really can't beat it for something plug and play.

Ok I'm exhausted it's been a long day non stop. The stand is built for the tray and the 600 is hung vert in the center over it. I would have 4 feet to the glass of the raptor or 5 feet to the ceiling with the bulb bare. I turned it on let it warm up no issues with the breaker etc. Just gonna slap up some pics. I need to order one fitting online and then the hydro will be ready to go on this side of the tent. Next is to get that done and get the trellis net setup around the sides and the back wall. This bulb is BRIGHT hanging bare let's see what happens. Need to get a fan under it too but I think this will work. Time for a smoke break I need some meds for pain. All this crap with a fractured shoulder is no joke helped my bro cut his grass too that was the trade of for his help running me around to the hardware store and helping me build stuff. I'm happy with how the stand turned out with the res and the lower height vs the veg tent. I don't think I will change the stand design in the veg tent as I don't see height being an issue there. Got the last two plants in veg into the 9" pots, topped off the res in veg and adjusted nutes accordingly, and the closet is rocking with the flood and drain and the clone dome as well with the T5 above. I took 5 cuts off of each of the moms the Peach Puree, Blood Diamond, and the Suzy Q.

I am thinking of an 8 plant setup with the vert two up front on their own with stakes and then two on each of the three "walls" with the net. I think it would be better to just use the net as a guide and not necessarily stress the plants weaving them through, any thoughts on this?

Anyways here's a few pics, also the girls in flower have started to bulk up and really push out the frost wow..........

Thanks for checking in
