left and right ?????it puts light into the hood at 360*, and is pushed down to the canopy, plus its alot closer ? supplement to existing lighting ???lmao
horizontal or verticle hoods(reflectors)......?????

interesting theory the mind boggles ,
why do you think your getting best light coverage form a horizontal ????

actually vertical set ups dont reflect the light they emit it............ and the best set up for a vertical light is a circle of plants and the light in the middle......and there is no right or wrong answer tho but i think that horizontal is better because there must be a reason why people use them in major grows think about it they hire scientist at these seed breeding places to give plants the optimum nutts, soil temp, humidity, genetics, and light!!!! what do they use horizontal lights with reflectors point blank...

That hood doesnt relflect it 360... The hot spot in the bulb is in the center of the bulb. It seems like it will slide right past the reflector, Jorge Cervantes and Mel Frank (Weed Celebrity's) Strongly recommend to never buy a light like that. Especially if your trying to get the most effiecent lumens per square foot, I have 4,500+ Lumens or more per SQFT and its reflected all on my canopy and roots. You tell me whats more efficient? Your light conversion chart is composed with horizontal controlled experiments, Its whats best.

and you prolly have a old bulb in that horizontal set up you have...............or you meter is wrong no matter what a horizontal unit will give more lumens than a vertical unit
think about it the bulbs are the same basically except ones shooting light in 360 degrees and one is all focused down...so what you say it losses 40%(witch i dont think is actual facts but ill run with it) that means that you have 60% of the light from the other side of the bulb going down so thats 60% more light than the vertical unit going to the one plant.

but my parabolic hood is reflecting it tho , and i suggest you go to amsterdam , i have , and all breeding houses i went to are using parobolic hoods ? yes i have seen a setup like you say , kinda like a stadium deal , and is my lumens metre lying to me ???? how do you count for my hood being closer , my growing medium is fresher as not been pounded by heat ? i agree alot is down to genetics and strain quality, what about the other side of your bulb facing the hood ? 40% lumens are lost ? it may look like your plants are getting more light, but the plants are not using the light that you can see!! at least you gave a reason for your theory, +rep for that =D

ive got over 10,000 lumen per sq/ft with my 100w and hood horizontally hung.
and all of that is reflected straight back down into the plants, not go out then back up then reflect down more reflections = less lumens!
that hood will work fine and im sure you will grow some dank. but its def not the best out there. if you want a true canopy and lumens get a sun system XXXL hood and 1000w bulb. best hood you can buy right now its just gigantic!
I also Lst my plants so i want as much as i can shining straight down on them making those stems and lower branches get fat too not just the tops. with a photometer at the stems of my plants they were still getting i think like 3,000 lumens all the way under a 4ft tall canopy. but like everyone says its personal preferance. and depends on your style

Theres been a heated debate for years, If you ask people on a forum your gonna get mixed opinions.. You just gotta do you. I have been to Amsterdam as well, Barneys farms uses horizontally hung bulbs in the same reflector style that i own. Its preference, Im telling you in my opinion and in my garden style, I would rather hang horizontal. In Amsterdam they use vertical and horizontal mixtures, which is the best of both worlds, all light conversion charts of your bulbs, the graphs is with horizontal results. Its also more cost effective to run 2x 600Watt HPS lights VS. 1x 1000Watt HPS, Its a proven fact for more lumens per sq ft for the price.

i guess its like this ......
Horizontal puts more lumens down , but has to be hung furthur away from canopy
verticle puts less lumens directly down but can be hung closer and covers a greater area ,
thankyou all for constructive input,
all work i guess its what works in your area and works for you =D
peace all

i try ha another thing is how the light gets absorbed into the plant if the lights is on top it would penitrate through more leves directly i think it somthink like 70%percent of the light travels through the leaf.......im pritty shure with the light comming sidways allot less gets absorbed into the leaf and just shoots st8 through the plant................look at a plant from the top and then one from the side ther are al,lot more flat surfises to such up the light from the top

also the plants grow toward the light. If you have tried lst you would the plant ends turn up. If you grew with horizontally you probably have to rotat the plants everyother day. this would have the plants spending energy chasing light rather than growing taller and creating nodes, imo.......

It depends on the hood you have. Most people buy horizontal hoods so they can reflect back some more light to the plants.
Other people grow vertically so they can have 360 degrees of growing.
Also some use vertical bulbs for other reasons. I.e. some cone type reflectors need the bulb to be placed vertically (I wouldn't buy one of these reflectors). I don't see the point in a vertical style hood or bulb unless you're growing in 360 degrees.
Generally just stick with a horizontal hood setup.

no 1 seems to care about coverage or the distance between hood and canopy , funny that , as its what i wanted the info on mostly lol i understand why people like horizontal hoods , i have already decided vert is best for me!!
