How much Canopy is covered by 1k watts???

So basically i already asked the question but just in case i wasnt specific enough

How many square feet (meters if you have to but id prefer feet) of canopy does a standard 1k watt HPS light cover and i dont mean total space where light is reached i mean like how much of that light is optimal for the plants. also is there a difference of canopy coverage of HPS vs MH?

You can get a sweet canopy with a 4x4 or 4x5 area with a 1000 watter.

i have 1k watts in a 4.5x4.5 foot room with a 95CFM fan it keeps the temps nice, 30~C lights on, 22~ lights off.... im getting the same results as you.


my personal opinion, is a 5x5 foot area is optimal for every 1k watts you want to grow with.

whats up with those wires on the batch to your left. you trying to SCROG?
i love those grow tables. homemade???
too many buds i cant count them lol. how many plants per table?
are each of those lights 1k? whats your electric bill?
whats been your average yeild with that flower setup???


sorry for so many questions but your setup is almost exactly what i had in mind for mine. cept i think ur using hydro correct?

the area of coverage depends on the footprint of your hood. a super sun 2 won't get as much coverage as say, a vertizontal...

They are in 4x4 black tubs from hydo store. Foxfarm soil. lst and then lstd on screen. 3 oz per plant. 8 to 9 plants. 1000 watt lights. Navarna seeds from seed boutique.

Pictures of set up.

how long do you veg to get 3oz per plant?

In your pics is that the distance your lights are from your plants all the time? that looks so far to me.

i get my 1000 watts 18" or even closer with no heat probs. my hood is completely sealed and vented though.

yeah me too, like 14 and 15 inches. i got a crappy Sun systems hoods. Your buds look great, so i just wondered. i was actually going to upgrade to all cooltubes soon, i would like to get the lights to 11 inches or so.


edit- i am using a 1ks

i run 2000 watts in a 8x5 wit the 4 ft parabolic hood 12 inches above canopy

yeah thats close to what I'm doing. i am 105"x53" with 2k. The reason i asked was becuz his shit looks good. It doesnt look like it was grown with the lights that far away, lol! This has me interested.....

I just bought a light meter yesterday, and my lumens are ranging from 3,800- 5,900(averaging about 4,700)under a 95,000 lumen 600 watt HPS, covering a 4' x 4' area. So, those extra 50,000 with the 1000 watt light should easily cover 5 x 5 and still average over 4,000 lumens per square foot(the math says 6,000). If you run more than one light, they overlap and give you a little extra coverage. I am getting over 8,000 per square foot where the 600 and 400 overlap.

You must be running a light rail, right? How do you like it?

no light rail.. just two 4 ft parabolic hoods stationary over the canopy wit two 1000 watt quantum ballasts wit the lights on the yoyo type hangers by sunmaster i think which allows me to raise them when i need to work and lower them to canopy level when im done.. check out the perpetual link for my last grow harvested 2 weeks ago and the double vsion for my current

Shit, i misread that. I thought it said 1000 watts, not 2000.LOL Man, that's a sweet setup. I have one of those 4' reflectors too, and I love it. I made the mistake of buying a second one with a 400 watt MH conversion, but the bulb was way to weak for that reflector, and my plants stretched like a motherfucker.LOL I still have it though, so I guess I'll have to add another 600 or 1000 to the project.

get the quantum 1000 watt dimmable ballast three lights in one
