1000w HPS covers an area of?

[tekneeqs]

Hi,

Just a quick question. What is the space to be used with a 1000w HPS light?

I'm asking because I was wondering how much of these lamps I'd need to cover a space of 11x10.

a space that big would need 4-6 lamps i believe they do a 3x3 area

I HAVE 2 1000W HPS COVERING 18 PLANTS WITH A 6'X12' FOOTPRINT.

PLANTS ARE IN 3 GALLON POTS.

LIGHTS ARE 3' APART.

I ALSO HAVE A 1000W MH IN A 3.5'X6' VEG ROOM.

WHITE WALLS MAKES THE DIFF

it kinda depends on what type of hood or reflector your using .
are you trying to grow the entire 11 x 12 or is that just the rooms dimensions ? thinking big is cool but leave yourself enuf room to move around n work . my rooms 11 x 12 too and w/ cooltubes i think i can cover about a
6 x 10 ft. aera effectivly .
peace

Stop what your doing and read this and remember. I messed around trying to get more production out of my 1000s. After reading some threads saying their 1000s were at 10 inches and 18 inches I lowered mine. Also pumped up nutes to 1400ppm from 1200....End result fan leaves burned as fuck!
Did some research...If you have a good reflector you light should never be closer that 3 ft. It is pointless you have all the lumens you plant can take. Raise your hood and get better diffusion from refracted light and a larger footprint. 1000s are rated for 6x6 area. I use 4x4 tubs and the plants end up at 5x5. I use PL lights that have incredible coverage and light distribution. under the center of the light reads the same foot candle readings as the corner of the grow area.
If you feel like burning your plants lower your lights.

Disclaimer..you could run more airflow & keep the room cooler & keep nutes lower than normal & shut off Co2....etc but why? Your plants want uniform lighting and that is achieved through distance and refraction. That is an argument for running "less effecient" 1000s instead of 600s.

Drawback...height restrictions...

Good luck friends.. -J

in general most will cover a 4 by 4 or 4 by 5 area effectivly but it does vary with different reflectors as per the light being 3 ft away from the plants that is to far away, and while you should make use of refracted light by using mylar or something similiar on the walls.

i flowre w/ a 1k HPS in a 4x4 (feet) area

The buds that are grown with a light 12 inches away from the canopy look nothing like the buds that are grown at 36 inches away..

If you can not keep the temp down or cool the canopy then raising your lights may be your only HOPE...

But if you want forearm sized buds and actually get your monies worth from your electricity bill, the lights often need to be no higher than 12-18 inches...

A 1000 watt HPS with no C02 should yield 2lbs... This requires adequate ventilation and perfect light proximity..

A 1000 watt bulb can do a great job on a 3 X 3 grow space....

After that, the lumens are being compromised...

and NOW you KNOWM

attached are 2 pictures of a grow room with 2 - 1000 watt HPS bulbs on a light mover that are never more than 4 inches from the canopy...
