2x 400w or 1x600w?

[Hazelnuts]

I'll go with a CMH if you can provide me with a link to a grow shop that has them as a 240V version or at least is fairly cheap/has cheap ballasts and shipping to switzerland. Thanks for your pm btw!

Also could the ceramic bulbs be used in a standard 400w ballast or does it use a special ballast

 

[ginoberde]

I can purchase a 400w ballast over here but not the CMH bulbs
if I had to order a ballast from abroad the cost would not be worth it

You do need a 240v ballast, a standard 400w hps ballast, nothing fancy, no electronic ballasts! The lamp does not care about 240 or 120, a 400w is the same for both voltages. Follow the link in simba's signature to buy a cmh lamp.

I'll grow tree style, maybe a bit of LST, but in the end it's gonna be tree style. I guess I'm gonna go with a 600w HPS(I'd like to use a CMH but 1. they are expensive as shit and 2. I can't get them anywhere since I'm swiss)
But thanks for all the advice

You're rights, MH are expensive as hell over here in the EU, don't know why?
Have you visited hanfburg.de? Best/cheapest growshop I have found in the EU. If you know of a better one,please inform me! We European's should make a own tread, because we have our own problems with supplies and so fort

Dude, the voltage is determined by the ballast (most are switchable) the bulb is the same whether the ballast is running at 120,240,277,408 etc volts.

Stoned2Death has very good argument in favor of 2 x 400 vs. 1 x 600 - light distribution.. I'm just thinking - what if you hook the 600-watter onto a light mover: how would it compare to 2 x 400 W.

(For Hazel's practical purpose, though - if you could afford a light mover, why not grab another 600-watter instead. So the above question is rather theoretical.)

But lightmovers are really expensive,if remember right?

What is the legal status on growing at home over there in Switzerland?
I heard you'r government is growing some top quality bud for "aroma therapy", heh, I love that

Isn't that what I already told?

Samba, I sent you a PM. Also, I think I'm going to get 2 normal 400w hps, then, when the first round is done and has got me some money, I'll get two of those CMH bulbs, cause they look like theyre the shit! So my first grow won't be the best imaginable, but that makes the second one even better...

 

[simba]

Hzlnuts.. when ya do.. you wont go back.. Conosuor quality.. (impho Sun and CMH are Unbeatable Effects taste everything LOL)

now for light movers.. 2 400s hps or cmh vs 1 600 on light mover the 2 400s will give way more light allover.. the 1 600 is devided.. so basicly using a 600 for that much bigger area.. I only like light movers when you have the right amount of light and just using the light mover to simulate real sun moving and getting all angles..
a light mover wont give you more light..IMPHO>>

Hey Simba

Hey Simba

Hzlnuts.. when ya do.. you wont go back.. Conosuor quality.. (impho Sun and CMH are Unbeatable Effects taste everything LOL)

if what your saying is true then predominately outdoor strains like FS/Maroc, Mighty Might & other od strains not suggested for indoor growing would probably do pretty good under CMH & also equatorial sativas that tend to do much better outside than in would probably again grow much better under CMH than HPS ?

I believe cmh would be perfect for making seeds for outdoor strains, any opinions ?




thanx

 

[simba]

well in theory yes.. however i have not tested it..

yes the light is a big part on them but humidity and temps are also..
however even under hps even if u get temps and humidity to match the spd isnt there even with using mh and hps bulbs or even EYE MH BLUE one part of that is in equator there is more blue (ya and more red to) therefor keeping the plants shorter. also. under hps they would stretch..
so yes IMPHO they would do Very well..


As far as breading.. I would assume they would be healthier moms and probably carry over to Hartier Seedlings (as seed was made with Full spd) Just my PO...
and yes if you could grow the Outdoor strains under CMH you can Breed off them..

**Disclaimer these questions have not been tested so its best guesses and theory at this time.

 

[masterlow37]

well i see 08' answering all these questions, not to mention the 600 & 1000w cmh's !!!

 

[Colma]

wait, how is it possible that 1 600W produces more lumen output than 2 400s? each hortilux 400W is 55,000 lumens vs. the 85,000lumen of the 600W.
2x55,000=110,000. Am I missing something?
I would go with using 2 reflectors because it spreads the light more evenly

It's about lumens per watt - 600W bulb generally is the most efficient among the 'traditional' 400 - 600 - 1000 watters, and produces more lumens per watt than other wattage bulbs.

[simba]

ya 600 is more electrically efficient than 2 400 hps's
however 2 400 are have more growing efficiency IMPHO
and 2 400 CMH are even better cause inv sqr law of light and height..

but ya id rather run 2 400 hps than 1 600 hps.. (changes grow setup a bit)
