2 600 watt or 1 1000watt

You have 4x4 area? 2 600w is overkill and 1000w is probably also. Light's don't push out lumens and they aren't constant. Lumens decrease with the square of the distance and you need to be looking at foot-candles to accurate figure out your light requirements.

The 1000w lamp is going to have to be placed farther above the canopy so the 145,000 lumens it is 'pushing out' has to be translated to either lux or foot-candles based on if it is going to be 18" or 24" above the canopy.

A 1000w would be helpful if you are going to grow a few large plants where you need penetration below the canopy, otherwise the 600w will be most efficient and you will spend less on electricity for virtually the same amount of bud.
this is what i was going to say basically :

if you have tall plants then use the 1000 cause it will penetrate much deeper into the foliage
if you grow shortish plants then 2 x 600 would give you more bang for your buck

and personally i dont believe you can have too much light, just too much heat :)

Definitely man i myself dont have the spare cash to max out on lumens but if is in your budget go for it man! Ive seen a couple buddies grow with hids @ around 5000 lumens per sqft and have baseball bat colas! I would definitely like to see what 10000 p sqft can yeild! Like a couple people said , just make sure you carefully select your strain. you could have 250000 lumens a sqft but if you dont have a good strain you will still have a less than max yeild.. Good luck man, let us know what you decide on and keep us updated on your grow.:blsmoke:



well thank you very much to start, i will have great genes, i actually already do, whether i go with 2 6's or 1 1000, im gonna be up there in lumens per sq ft so im excited also, ive really never scaled up a big indoor thing before although ive had over 50 plants outside one year, im going to be excited to see if i can get like 2 or 3 ozs like poeple say per plant, kinda cool to think u can do what the sun can, i mean like i said i grew c99 inside first time grow indoor, i got like 3 ozs off of 3 plants, i mean thats okay but its newbie compared to some shiot i see on here, i just wanna go big or not at all, im not trying to go to jail but at the same time if im going to do it im not gonna waste my time and fuck around, i want the best possible results, anyways thanks again man ill be doing lots of outdoor this yr so ill keep u up to date on that, this is an ongoing thing for right now i plan on setting up shop come winter time for indoor, but keep an eye out for some outdoor shit coming up soon

im starting to lean toward the 2 600 watters, im not gonna have 1 ft tall plants but i wont have 3 or 4 fters either, im looking for like 2 ft or 6 inches more no higher, i think with 2 600's i can get them nice and close cause ill have em air cooled and get some good effeciancy, now, someone give me some good strains, favorites and grown strains only!

thats the way i thought about it man, if im going to jail im going to jail doing it the right way u know, i dont want no hassle, no bullshit, 100 percent business about it, cus like u said 1 plant or 100, 1 light or 50, i get busted im going to jail for a long time, i like that pic, is that 1 plant lstd or some shit? also u said u get 3 oz per plant in a 9 plant setup with 1000 watter, that comes out to 27 ounces per harvest every 3 or so monthes, which sounds what im lookin for, cus iwas gonna do 16 and hope for an ounce off each which would be a pound every 3 or so, so i like that idea alot, but could i optimize it with more plants or adding that extra 600 watter, thats the mystery:eyesmoke:
no thats one plant not topor any thing done toit.tahts how i cut mt clones. and that was'nt me cuz i get 4oz to 5ozper plant. this plant is ungodly compared to my last grows when my pant got 7ft indoors and i got 4 to 5 ounces per plant.

2 600w.
Why? Because I run that setup!

Why REALLY? Because with a 4x4 area you can use a MH bulb in the 600w and be just as efficient while vegging. (600w MH is plenty for veg). You can save the 400w used during veg and use 1 light. If you feel its necessary you can end up using both lights to veg.

If you go with 2x600w, you have the option of running 1 MH and 1 HPS. If they're on light movers, you have an amazing combination. Not to mention you can get the 600w closer, more lumens.

my .02 :D

cuz after this summer im going with 2 600wtt hps and use my 1000forveg. that should GET~R~DONE LOL


haha yea, why do u choose to only go with 1 plant? i can see the advantages, only taking care of 1 root system and such but u could easily incread yield by adding 2 or 3 more u know

could u tell me your results? have u run 2 hps for a full grow then 1 and 1 for a full grow? yes i would def save on energy and only run 1 for veg, fuck veg haha jk, what strains have u run under this setup, hydro or dirt? heat issues?

1 600 watter will cover a 4x4 area well.
1 1000 watter wil cover a 4x4 area very,very well.



you said u were able to get about 27 ounces per harvest using 1 1000 watter, is it on any light movers? do u experience drastic bud size on the outer edges of your garden? are all budsites covered more than sufficiently?

You're asking the right questions, keep it up.

BUT, the downfall is I'm a first time grower. I am running 12 plants and hoping to veg them to get niceee and big. I have a small yielding strain and I'm hoping for my first ever indoor grow to get 16 ounces. People say EASY but its my first grow. If I get anything better ill be WAY more then happy. The first 3 weeks has been MORE then slow. here is a link. https://www.rollitup.org/indoor-growing/154500-8x4-1200w-og-kush-1st.html

No light mover.

The 1000 watter cast the light even over the area. Perhaps off a cunt hair, but even.

27 ozs with 1000w is nice, what was your veg time? what kind of bulb? what strains and nutes? what kind of reflector?

4x4 is too small of an area to use a light mover, just get a high quality reflector and a single 600 or 1000 is sufficient coverage for that area. 2 600w will be a waste IMO, unless you do what bterz said and use 1 HPS and 1 MH. There does seem to be an advantage running both spectrums during flowering, hence the extended spectrum and dual discharge lamps.
