1k Watt vs 2 600 vs 8 bulb T5HO

[bankcee]

I know my yields will be better, generally with the highest amount of watts, but in a 4x4 scrog, what light would give me the fastest growth. I wanna fill the screen 75% before the flip and I wanna do that in 4 weeks.

will the 2 6s cause the plants to grow at a faster rate?

or will the t5 or 1k?

2x 600 watt would be my choice

I'm with @ISK on this one .

but is it going to cause for faster growth. cause I wanna fill a 4x4 scrog net about 75% in 4 weeks veg. I1 wanna do 4 week veg transplant with superthrive and some mycos and flip the lights.. let them stretch for 2-3 weeks to fill the net and watch them buds fill out? you think the 6s will make it possible?

Just don't do the floro.

2x600 would be "fastest growth" and the most light; but a single 1k would be easier to cool.

If u can make it work then 2x600 > 1k >>>>>>>>> >floro for this case.

what do you think? is the growth from the extra 200 watts really noticeable? or if not should I just stick the 1k in there with the ease of cooling? Or would it be close to similar on cooling? cause if the growth is 10x faster than the 1k but 10x harder to cool I'll figure that out. but if it's 1x faster and 1x harder might as well stick with the 1k. lol if that makes sense.

but what's your opinion? I'm in socal and summers get pretty hot here I'm afraid of the heat being an issue at that point..

Air cooled 1000w with low iron glass

2x 600s is a better footprint and 1.5 X as much light put out. 600 watt hps are the most efficient hid bulbs.

the 600w hps is the most efficient light output per watt of the HPS. So 2x600w hps > "1x 1200w hps." The issue here would come with trying to cool two hoods next to each other because your inline fans will lose a rediculous amount of CFM with the bends that would be required. You would probably need like an 8-10" 700-1200 inline fan.

but yeah

2x600w hps > 1200w hps

2x600w hps >>1000w hps

BUUUUT, if temps get out of control cuz the double 600w, then maybe the easier to cool 1000w would be better.



Also Sun Systems LEC315 exists, I think 2 of those would perform best.

those extra 200 watts could be an extra QP pretty easy

IMO just start with a single 1000w HPS with like a Magnum XXL hood. Its the safest option. Maybe after running that for a while mess around with 2x 600w.

If it were a 5x5 tent then I would definitely go the other way and do the 2x 600w, but for a 4x4 a 1000w will do great

Ime 2 600s are easier to cool than 1 1000.

Do u have a pic of 2 600s being cooled?

Honestly I was making an assumption based off the fact that you lose a ton of CFM when you start curving your ducting, so the 1x 1000w being easier to cool i suppose was more based off of my understanding of fans/ducting

Keep your ducting straight. Lol it doesn't have to bend to have two hoods running. Make sure you cut you ducting to exact lengths. I'll throw some pictures up when I get back from vacation of 3 X 600s with 1 inline 8" no ac.

Hah that sounds like a saying. Guess my brain was overthinking it.

OP, 2 600w would be like 25%+ more light than 1x 1000w, so if its just as easy to cool then the 2x 600w is probably a better idea

I think it's almost 50%. 600=90000l 1k=155000.

na 2x 600w would be 180k vs 155k. So an extra 35k

I think were confusing each other O:


OP Until you dial in your grow space I don't think it will make a dramatic difference, once you do dial it in it would likely make a pretty awesome difference to have the correct one

if your able to tell and show me how to cool these 2 6s, i'll be forever in debt to you. lol
and i'll def do the 2 6s my next grow.

Truth is forget about the lumen idea means fuck all ,, what you really need to decide is what kind of yields you are looking at..
600's are more efficient watt per watt but this can be confusing
Take a look at what people are honestly pulling as in yield its know where close to 600 dry grams there usually 400 - 500 grams truthfully speaking sure some are killing it
But lets not forget about them 1000 watt bad boys now they throw out power as in par when comparing them to 600's and also you will get well i can run my 600's lower sure you can shit i have run my 1000's open ended 14- 16 " from plant tops. with out any issues aslong as you got good cold air in between canopy and lights ..
but the problem is coverage lower you go less coverage you got
Higher you go with 600's par is shit
so with that said with a canopy height of 30" a 1000 will destroy 2 - 600 as in par , a 1000 20 - 30 inches from tops its litterally same par ..
do this to a 600 watt set up and watch that par drop drastically

So with all this said what are real true growers all BS set aside really getting close to a pound + couple oz ????
Years back one of my first indoor grows experienced grower thou .. with mag ballast and medium yielding strain i pulled 2 .5 pounds off 1 - 1000 watt light
now years later pulling 3 pounds and just under 3 pounds consistently ..
You are not going to pull that with 2 -600's so where does it end right ???
and like i said search the web what most are pulling with 600's seriously there is lots of BS out there as for people calling yields but seriously , they do not call them 1000's the Bad boy on the block for no reason they pound out yields

so this is exactly my aim. 4x4 tent scrog with 4 plants. 4 different strains, similar growth strains of course so the next is larger than the next. idk maybe 10 gallon smarties.

wanna do perpetual and pull 2 pounds at least 1. 4 week veg? sound insane? every 4 weeks.

 

[2ANONYMOUS]

not with a 1k its not its lots of work i did perp 3 rounds harvesting 8 pounds every 2 weeks and its lots of plants at different stages clones pre veg and veg pulling plants all the time and plants in all the time to get 2 week harvests TBH i was burnt out after that and said fuck that no more
