1000w v 600w

[rangersroy]

i know 1000w are better than 600w but if you had 100m2 and 60000w would it be better to use for yeild 100 600w lights or 60 1000w in 60m2 for a better yield or would it end up the same so equipment wise your still better with 1000w

[nibec]

most 600 watt hps bulbs acutally perform more efficiently than a 1000 watt hps.. more lumens per watt

you can get 600's closer, and overall, overlapping 600 watt bulbs will result in better yeilds.

running 10 - 600 watt hps bulbs, is better than 6 - 1000 watt bulbs, although setup would cost more.

however, you could go really expensive, and get some dual arc 1000 watters.

that would be (per bulb) basically, 600 watts of hps, and 400 watt MH in ONE bulb on ONE 1000 w hps ballast! ... now thats cool... veg with the same lights as you flower with, and get the best of both worlds plus more!

I concur, if cost is not an issue go with the multi 600s.

WOW! I wish the grow shop guy would have said something to me about that! My friend has a 400 W MH and was going to go with a 600 HPS for flower, that would have been perfect! we are using the old style ballast because there are only a couple bulbs made for digital ballast, and growers are reporting burnout rates of bulbs in as little as 6 months. So anyway, now he has to buy another ballast and bulb. 2 questions, how much do this cost and what about using a single 600 HPS in a 5X5 area? we thought about switching to a 1000w hps, but I read somewhere that a 600 would work better...what do ya think? Peace

600 watts can easily cover the 5'x5' area if you use the right reflector!

1k for sure! I used to grow under 600s I just got my 1k in Nov and I gotta say my overall bud size and yields have doubled! Same strains, results don't lie, plus the fact that lumens don't add up 140,000 lumens penetrates deeper into the canopy than 90,000. I have two homies that have switched from using (2) 600s to 1k(s) because I now yield more than both of them, I am using a light rail but I grow organically and they use Advanced Nutes Connie line. 600 = nice yields/ 1k = bigger yields!!

Lets not forget the brand of lamp your using. There are many different variables that could play into this. I actually use 1k's for my 2bdrm apt grow and 600's for my 1bdrm apt grow. Now the 1'ks actually perform the same as the little ones, it really comes down to HOW your using them; distance, positioning for maximum overlapping, air cooled or not, etc. The brand of the lamp is what your going to best determine the power your going to receive. I believe they can be equal, just depends on the grower and the ability he/she has to maximize!

I've got to weigh in on this one, I love the 600. I use a GE Lucalox with an Adjust a wing reflector. I have been using it in a perpetual grow for about a year and a half. The yeilds are not spectacular but they are ok. I figure with the amount of money I am saving on electrical cost due to exhausting and refreshing / cooling I'm better off in the long run. I use 2 8" duct fans to exhaust and 2 6" fans for intake, 2 recirculating fans for mixing and 1 tiny fan to cool the ballast. My room is 5' wide by 8' deep and 8' tall. I started off with 4 plants 24" tall and was yeilding 1 to 1 1/2 oz per plant. I have 8 plants under it now, each about 30 to 36" tall in 3 gal pots, 5 different strains. I do a version of lollypopping and some bending on the sativa doms and am yeilding about an ounce per plan and harvest about every 10 dayt. I'm not in it to break the bank so the outcome is acceptable.
I would like to try another 600 watter overlapping but space and money say no right now. In my humble opinion the 600 is a great tool.

600 watts can easily cover the 5'x5' area if you use the right reflector!

I go by:

2x2 = 250w hps
3x3 = 400w
4x4 = 600w
5x5 = 1000w

Now on the other hand if you have your setup dialed in with area and ventilation you can up the power. I ran a 600w in my 4x4 for a year and did good, but swapped to a 1000w in the same tent and now have great yields. The 600w is good for the 4x4 but I just didnt feel I got full amount of light to the edges of the 4x4. My buddy runs a 1000w dimmable dimmed to 750w in his 4x4 and does as well as I do from my 1000w at 100%. 750w is just about ideal for a 4x4 tent.

4 x 4 tents....4 x 250 w every time, double the light of a single 1000w and half the heat...

Double the light and half the heat??? How so?

[eye 1 der]

inverse square law...I = 1/d2
light intensity (I) =1 divided by the distance from the light source(lamp) squared (d2)

[growcraze]

eye 1 der got real technical on us with that one... lol What's the recommendation for a 400W area 2x6?

I think ganjadin said a 600w makes a great tool... My opinion is that there's the real answer, all this equipment is just that, tools in a toolbox. And like someone else said, it depends on so many variables. Certainly some tools fit some situation better, and its the creative mind that applies those tools and materials that maximizes any particular set of circumstances. After all, that's the fun part right? That's the REAL therapy, the therapy of creation!

But, for the hypothetical question posed at the onset, holding all variables constant (i.e., you can cool the suckers down enough and not counting the logistical nightmare of venting 100 lights as opposed to 60), my guess would be the 600's, cause you can get them closer, cause like homie said, the upside -down square and all that science and stuff.
