I mount mine horizontal and use LST
yes but why do you think horizontal is better i am interested in ??
i dont think the fact you are using lst is relavant as im sure your only doing that because of limited height ?

A parobolic hood with the bulb hanging vert , can actually be placed closer to your canopy , as the heat is dispersed sideways not down to your canopy ,
i am wondering this ,
a vert bulb pushes light out to the sides, and a horizontal bulb pushes the light downward, but only from 1 side the rest is slammed into the reflector ,
i guess my question is which way sends the most light to your canopy ?
any more info that is useful a REP will be given......ty

No I don't have any height limitations really, I do LST to get some "sun" on the lower branches 'cos in nature the sun moves and I don't have a light mover. That being said, The sun is strongest and longest from above than it is at sun rise and sun set so therefore my light is hung above. I do have a couple T8s hung on the side though!

A friend of mine recently went from a horizontal 400 watt hps to a 1000 vertical hps. Aside from the need to rotate the plants continuously it seems to use almost all of the light. I think if it works for your space, that would be the way to go.

Horizontal is better because the majority of the light that coms off a bulb comes off the sides this is true with most cfls and mh/hps systems

and what about the side of the bulb that is rebounding from the reflector ? this alone loses 40% of its light just doing that , plus with horizontal more heat is aimed toward the plant , sorry i dont agree..........

ahh i see , well the side lighting seems like a good idea , dont forget tho , even growing outdoors they dont get pure 12hours sunlight, plus cloud cover ,shade caused by diff things and of course the days when it rains , i am gonna rep ya for your info ....=D

just a thought , i wonder if anyone has tried growing on a glass shelf and shining light up from below ?? theres a thought .....

ok well it all depends on how your room is set up you say that the light bouncing off the reflector wasts lumen's but i think your wrong lets say you have 1 plant

a horizontal reflector at least bounces light back at the plant with a reflector a vertical one doesn't so if there aren't and plants on the other side you get what gets bounced of the walls and more heat is aimed at the plant because more light is aimed at the plant instead of radiating in a 360 degree circle its being focused down

i disagree again lol sorry , its the change in light direction that reduces the lumens , my grow area is the same shape as a teepee tent, and i would add again , my vert hood can be placed much closer than a horizontal hood (fact) i can put the parabolic a few cm from canopy as oppose to the horizontal 1 that needs to be a foot and a half away....+rep tho for ur input.....

Hang horizontal, it reflects light down to your plants if a efficient reflector is used... I have seen vertical setups, you need to be careful when heat spots if hung vertically. Good luck

so verticle does not then ?? heat spots are a danger in any set up ??? read the question , they both reflect light , which is best ???

I just told you.. Horizontal is better, It reflects ALL LIGHT DOWN. If your asking this question you definitely shouldn't even consider hanging your lights vertically.

Hanging vertically aims light to the left and right of the bulb and not down on the canopy and roots. Most people hang vertical lights as a supplement to existing light. No offense but you got probably the worst reflector on the market.

you just told me nothing ......it does not reflect ALL light down, 1/2 is pushed into the hood when 40% of lumens are lost, what are your reasons ???????????
please note i have always grown vert for 5 years , i am looking for valid reasons not mish mash, deffo shouldnt hang vert so tell me your reasons , i have also a 600w horizontal diamond hood , and my lumens metre is telling me that my parobolic hood is putting 14% more lumens to my canopy so you are wrong, im looking for overall opinions , how can you make such a statement when your horizontal hood is at least a foot more away from your canopy , be constructive plz , and add reasons not just bold statements that dont add up, thanks

ya and if your trying to mimic how the sun moves around plants and gets all of them,
I had a crazy idea for when i actually have money and no worries.
take a square room and cover all the walls in T5's and the ceiling. or whatever light, i would use t5 because of the fact they are eay to habg and square so they would all fit together without too much heat.
then use times to make it so that say 1 side of the rooms starts lighting up at 5am then in succession like how the sun goes through the sky the rest of the lights turn on till finally at mid-day all of the lights are on then they start turning off from the side they started on.
so basically a room of just lights that mimics the way the sun moves.

But hey just a theory. im pretty damn stoned as it is but i think it makes sense.

but right now i use a horizontal 1000w best light coverage of my whole room by 1 reflector
