1000 hps vs. 2x 400 hps?

You are seriously going to claim that 1 x 1000w will out perform 2 x 600w?

That is absurd. That has to go down as the most Ridiculous Claim of the Year. I have grown with 2 x 600w before upgrading to 2 x 1000w. I can honestly say I can grow a fuckload more with 2 x 600 then 1 x 1000w.

It's the claim that EVERYONE I know that has used 2 600's and changed to a 1000 makes. 9" here says the exact same thing.

Why not run CFL's? They are way more "efficient" than 1000w lights hands down....ohh that's right, it doesn't work like that.

And the most absurd claim is definitely that a 600w light is more efficient than a 1000w light JUST because it puts out more lumens. It falls short in the only thing that matters to me $/gram.

as i have said iv grown side by side in the same room but split in 2 and venting one room in to the other i.e i could not run the 3 bulbs together so in the winter the dark room would get the heat from the light room and then it would change round i.e growing 24/7 but always in 12/12 saves a shit load not needing to run heaters and air con doing it that way.

the 2 x 600 yeild around the same as the 1000w may be a bit more, but i get over a gram per watt from my 1000w but dont get it with my 2x600 work that out? yeild comes down to the grower and since im the grower of both rooms that use the same soil and feed same extraction same air venting in and out of each room and both rooms on the same extractor fan pumping to the air out doors ( 3 fans 2x6" 1x8") over all i grow more bud per watt from the 1000w than the 2x600 and iv been doing it that way for the last 5 years or so.

Well you cant compare CFL to HID lighting...


Seriously though. 200k Vs 150k max....You tell me whats better? Theres no comparison.

If your not yielding as much with the 2 600s vs 1 x 1000w then get them closer to your plants or go back to the drawing board because you have Issues.

Theres no comparison. You and 9". Thats 2 people compared to Every other grower on the planet who knows what they are talking about, will tell you 2 x 600w will yield more then 1 x 1000w.

Not only do you get 2 points of light. 600s are more efficient for Watt/lumen and have a Lot less heat so you can get them closer.

The way I see it is 2x600 would be more efficient because you can cover more sq ft.

4x4 for 1000w and 6x3 for 2 600w.

yes but the deeper penatration = more bud under the canopy 4x4 room with a 1000w will grow good sized buds 3 feet down the plant 2x600 will grow good sizes buds 2 feet down the plant, plants grow 3D not 2D or flat canopy.

you can play all the numbers on paper and what should be better, but put that in to practise and you will find out something diffreant .

have you seen the size differance of colas grown under a 1000w to a 600w light???. look at it like this

1000w room 4x4x3= 48 feet cube'
2x600w room 3x6x2= 36 feet cube'

again plants grow bigger under the 1000w than a 600w each 600w covers 1x1m that grows bud worth while 2 feet down the plant. a 1000w will grow bud worth while 3 feet down the plant what room as the more room to grow bud in?

ps
put a 400w next to a 600w your eyes will see a small noticable differance between the two put a 1000w next to 1x 600w and you will see ah huge differance like fuck i have to turn my head kind of differance.
I can look in to the naked 600w bulb for a 10-20 seconds i cant look in to a 1000w for more than 2 secs its like looking at the sun.

I would certainly hope that you could achieve very similar results with the 2 configurations, all things the same you actually should achieve approximately the same result. The difference is that you can achieve it in a smaller space w/ 1x 1000w light.

BTERZ, your setup is different because of the dimensions of your room. I definitely agree there's times for each configuration depending on the size/shape of your grow space, but given say a 5x5 space to grow in, I would design a 4x4 area to grow w/ 1 1000w light.

But given your shape/sized room I would definitely use 2 600's. Well, I'm a bit of a lunatic, so I would probably end up with 2 1000's because I LOVE bud.


You also have to figure the cost of the lighting into the equation. I can get a 1000w light for about $500 total. I can get 2x 600's for about $950.

That's a $450.00 difference! If I'm going to yeild very similar and use less power with a 1000w and my grow room shape/size doesn't dictate the I should, why would I use 2x 600w's?

I guess if you are doing a SOG w/ very small plants it migh be worth it to do that way (even then, eh), but if you veg your plants at all, that 1000's gonna light the 2x 600's up.

Where do you shop? Everywhere I looked, 1000w ballasts cost considerably more than 600w. The difference between 600 and 1000w ballasts seemed a larger jump in price between 400 to 600w.
I paid about $360 for my electronic 600w, Radiant 6 reflector and Ushio horticulture bulb including shipping (therefore a little less than double if I got 2, so let's round down to $700). The same dealer I would have paid almost $500 for the 1000w of the same setup, very similar to your estimate (Lumatek ballasts are about $115 more for 1000w than 600w).

If you use a cheaper setup for example, from the great equalizer eBay or HTG supply, the 1000w setups cost on average $100 more than a 600w setup, even with regular ballasts. Add the cost savings of a dual 600w ballast into the mix and someone could easily buy a dual 600w setup for around $500 still paying less than $.50/watt and a much smaller difference in startup costs than you claim so either you are ignorant of the cost difference and failed to research it before you posted the wrong information AGAIN, or you are a liar that uses artificially inflated numbers to win a debate.

just x2 the £££ will be around what you would expect to pay in if £100 = $200 http://www.greenshorticulture.co.uk/Grow-Lights-182/Grow-Lights-189/Cooltube-Grow-Light-786.asp

you would want cool tubes to run in a small room such as 3x3 or 4x4 so you would have to buy an extra cool tube if you go for the 2x600s + 1x 6" fan will do up to 3x 600w and up to 2x2000w using a 6" ruck fan. that would just do the lights in the cool tubes you would need another fan sucking air out of the room its self if you only use 1 fan and vent from in the room you will be fighting low humidity in other words make 2x6" holes with ducting coming in one side and going out the other side with the cool tubes in the center of the ducting thus no air from the room is vented out making the air humidity nice for plant growth you will be much better off if you intend to use C02 later on.

2 x 600w with cool tubes = £260 or $520
1 x 1000w with cool tube =£189 or $378
cost of replacment bulbs 2x600w £40 or $80
cost of new 1000w £45 or $90

everything else will cost the same fans ect..

Cost of the equipment has absolutely Nothing to do with this. Initial cost of lighting has absolutely No relevance to the fact that 2 x 600w will grow more then 1 x 1000w and do it more efficiently.

how much does it generally cost to be running 3 600watt HPS lights electricity wise? will it be putting a heavy dent into the electricity bill?

eletricity costs are negligible when you only run a couple of lamps

whatever you pay for a kwh on your electric bill x that by 1.8 and you get your cost for 3 lamps per hour

why dont you and mindfuk get a room together? you are so far up each others arses!

I know what your going to come back with next thats how predictable you both are your thinking along theses line in your next post

"Hahahaha. Wow Im sorry, Im trying to keep it friendly" or something like that and you love the word absurd in most of your posts, if you think im ridiculously unreasonable then take a look in the mirror

no you are not trying to keep things "friendly" at all you are trying to do is stir shit up in this thread and alot of others threads all the time. you think you have the last say in this> https://www.rollitup.org/indoor-growing/181185-what-plants-food-5.html

i can find more flors in the both of your last posts under the one i last made than you both can find in all of my posts.

BC big cock have you run both rooms? if you have then please say so if you have not shut the fuck up! you are only speculating on an out come that you have no idea of because you have never run it in practice only in theory.

you and mindfuk are a bunch of kiss-ass let real growers get on with growing and why dont you 2 do one in a motel

ps
i talk to a master grower in botany in the real world of growing cannabis

taka a look at my pics AKA scot blaky (shantibaba) look it up!

^ Excellent advice. If the two move in together they can grow with 2x600 AND a 1000. That'd be awsome. Please post pics !

Wow! You really are a sad, angry person aren't you?

Interesting that you picked this response of BC to rail on about him and I agreeing, when he had a totally different take on the red-herring about start up costs.

He said he doesn't think they are relevant to the discussion, I never said that and in fact agree, that initial outlay of money may determine if one chooses a single 1000w or 600w. Personally, it should depend on the grower's and growroom's need, not pocketbook but the fact is, we weren't in complete agreement on that topic.

Your emotional outbursts and personal attacks will not continue to be tolerated.

Lets put it this way.
2x600 will cover a 3x6 area no problem.
1000w will cover 4x4.

200 extra watts, a bunch more lumens, and more cover area.

like BC said, if you cant get MORE weed from 2x600 then you have some SERIOUS problems.

Do you really think you can fit 12, 3 foot tall plants under 1 1000w?

BTERZ, try it. No one said you can fit 12 - 3' plants under 1 - 1000w light. (But I can show you pictures of someone who does), the point is that 10 - 3 foot plants under a 1000w light will yeild more.

Instead of speculating, try it. I don't disagree with the idea of multiple lights (obviously) and I don't disagree with the idea of growing alot of plants (obviously) in a short period of time.

I do disagree with 2x600w's being more efficient than 1 - 1000w light. What you're not seeing is that 2 600W lights doesn't equal 1 - 1200w light.

Especially in your scenario where you don't have the lights overlapping much. You are basically doing 2 600w grows. Which is a good use of space, but you could've grown equal or more bud in less space with less electricity using a single 1000w light.

yes you can the same as you can fit 16 to 36 in the a 4x4 room under 1000w and grow buds like this




16 plants with 7 days veg = 79 grams per plant. work it out your self


been there done that i also use 2x600 what do i hve to brag about??? if ii grew bigger buds and more yeild i would be the cunt saying 2x600 are better than a single 1000w.

Why would 2 x 600w be a 1200w light...? 2 x 600w lights is 2 600w lights and thats why its better then a Single 1000w.

600w lights are the MOST efficient for Lumen/watt. 1000w is no where near as efficient as a 600w HPS light as far as power/lumen output.

I dont understand how you can possibly think 150k lumens at 1000w can be better then 200k lumens at 1200w.

We agree on indisputable facts and that makes us "up eachothers arses"...?

What are you 12?

So does that mean you think Everyone who agrees with undisputed facts has their head up their ass?

Do you ever feel like everyone else is an idiot and your the only smart one?

Maybe thats why only you can comprehend that light is somehow food..
