Multiple bulbs in vertical grow - inefficient?

The primary benefit of vertical growing is that you take advantage of 360' around the bulb, and the floor below, right?

So, for the many vert setups that use 2 bulbs, are you not counteracting this benefit by having the light between the 2 bulbs being wasted?

Shouldn't all vert grows be done with a single bulb?

Yes, I would agree. But when I am trying to grow as much pot as I can, in a small closet, I have to just stick lights everywhere and anywhere that I can place them..

Roseman, I don't disagree with your use of lights. I'm speaking of colloseum type grows with the lighting in the center, surrounded by plants.

I was jsut saying that takes a lot of room to do.

ive seen what ur talking about but not what ur thinking. ive seen where they have 3-5 lights haning in the middle but instead of side by side like ur thinken they put one underneath the other, since very little heat comes from the tips

...they say that not a lot of light is wasted at the 'tip' of the bulb... that most is emitted along the sides of the bulb (hence horizontal placement in fixtures in a flat grow).

many vertical grows don't actually even bother to use the 'floor' space, just using the walls. you have more sq. ft. of canopy, but the canopy doesn't seem to be equivalent sq. ft. wise (a flat canopy allows for better bud growth per sq. ft.)

the real benefit of vertical growing seems to be in it's ability to maximize a limited space. if you are limited more by Space than by Electrical Consumption, then VERT is the way to go because you can use the top half of the room, which would otherwise be wasted.

if space is not a limitations, but rather electrical consumption Is, then a vert garden seems to offer only marginal gains for the amount of increased time in the garden. I have yet to see a vert garden that blows a 2 gram a watt Flat garden out of the water (please share links if you have one)...

also take into consideration the VEG time needed to properly fill-out and train a vert garden. if it takes longer to veg in a vert, then any gains that you see per watt may just be a factor of increased time.

recently saw that ALL gardens should actually be broken down into a formular that takes grow time into a account... something like Gram per Watt per Week... so that the ACTUAL efficiency is determined.

AeroKing I get your first question, and I think I agree that light is wasted. Most light comes off the sides of the bulb, not the tip, like DaGambler said. So the sides of the bulbs facing eachother is wasteful in my opinion. It'd be better to put a wall with plants on both sides, between the 2 bulbs. I DO NOT HAVE ANY EXPERIENCE WITH VERT. I am still on my first grow even. I just figure that it seems pretty easy to figure out it'd be better to have plants between the bulbs than not. See what I mean in the pic? JUST MY OPINION. PEACE

the guy that grows like this is a god in my book. he grows other ways also not just vertical. all it takes is experience. in the middle on the floor is a fan blowing straight up to cool the bulb. im going to try something like this useing cool tubes.
i like the idea of doing horizontal for indicas and vertical for sativas.

tell me hes rotating them plants, i dont see any other way hed get such fat nugs on the parts of the plant that arent facing the light

i beleive he rotates about every 3rd day early on. once they start getting big he ties the back branches towards the cage and just tucks everything best he can.
i think nowadays he also provide some side lighting in the 4 corners.

This is exactly what I'm talking about. That makes sense. I'm saying I keep seeing threads(not just RIU) on vert grows that are using two bulbs hung next to each other in the middle and no plants between.
It just seems like a waste to me.

I'm trying to plan a vert project and I'm just looking for feedback.

As far as plants on the floor, I understand that the real point of vertical is to use the walls, but I've seen grows that utilize the floor space as well. The way I see it, is again, this maximizes all of the light being emitted by the bulb - bottom as well as sides. I don't see why you wouldn't use this space.
I saw that one with the box fan in the middle, but it seems to me that a cool tube could accomplish the same effect, but only take up 6" diameter of floorspace, leaving room for several more plants.

Now, the real challenge for me is going to be trying to design the system inside of a box. How can you use 360' around the bulb, but still be able to access the middle?

heres those pics back up. i just wanted to get permission from prawn over at the planet before i left these posted up here.
