it was the lamp not the fixture
the phillips blows all cmh lamps out of the water
but honestly
for the money
and high production
I say
run 2 1k's
or less watts and more production
3 60o's with your open batwings
only 200 more watts than a 1k + 2 315's
but much more efficient
I always come back to the issue of bulb life...
One thing is for sure I will agree with you on..
it is better to have multiple lights of a lesser wattage,
than 1 or 2 of high wattage...
We talked one time about gpw,
and gram per Sq foot...
We kinda just barely touched the surface...
So in this, im gonna guess we are more concerned on how much is achievable from a giving amount of space if all varibles are accounted for and tuned in... which in this case is 4x8x6
So the question,
What would yield more?
We are gonna do a little comparing.
We are gonna make all the variables the same
EXCEPT the light...
And for my reference we will use my setups configuration...
So 4x8x6 tent
c02 1200-1500
Ac controlled
rh controlled
We will assume your the grower, and you are using what ever growing technique you would use in this situation,
which im gonna assume is the canopy control top deleaf that you have had me watch 3 hrs of :)
lol Was very interesting, but now you got me hooked, and i got to keep watching :(
So here is our selections....
1. (2) hps 1000 (super horti bulbs)
2. (3) hps 600 (super horti bulbs)
3. (4) cmh 315 (Phillips bulbs)
5 . (2) cmh 630 and a 600 de (with the optional wide throw reflector)
6. (6) cmh 315's staggered = = = (Phillips bulbs)
Maybe there is even some more configurations im not thinking of..
I think it would be wise of me to note, and get your comment, as to
some of there are a overkill of light IF NOT for running c02, eh right?
I dont want to send nobody shopping for a light to big without understanding that..
I also know that there is a huge difference in upfront costs for these, which would play a factor in the decision a person would make. Some would also run cooler saving money on AC, but by how much is the question. AC is expensive.
So the question isnt which is the best choice upfront money wise, but yield, and yield only...
This is more along the lines of which would yield better because of light distribution, spectrum, and heat dissipation....
So if you were having a yield contest with your buddies but you got free pick of what lights to use, which do you think would be the top performer?
On a side note, between me and you, if i did go (3) 600
I mean keep this in mind,,, for my 3 600 watters replacement of bulbs( I use super horti, and I like them) is gonna be $200... and thats every 6 months....
This however doesnt play into the equation of my prior question of which would yield more...
Just ponder on that for awhile today...
I got to mow the yard. ugh, I hate physical labor anymore...
I also hadnt said nothing, but a few of you know i got some hella back problems, and im gonna go under the knife sometime in the next 90 days... so im gonna be off work for 3 months are so... Getting down in the grow room and doing much of shit for the first 2 weeks is prob nil... Im thinking i will have the pheno run done, and i will have a couple mothers and fathers and i will just bring my 3x3x5 tent up and put the 400 watt mh in it in my bedroom. As for as im concerned, if my bedroom is livable for me it will work for them. Just old school it with just a fan/filter/ speed controller.........
