question on tent size?

Planning for 2x 5'x10' secret jardin's w/ 2 600w HPs in each tent. Will the 2 600's be a sufficient amount of light IYO????

You need at least 2500 watts to fill that space completely with light so I would say 2 air cooled 1000's or 4 air cooled 600's.

If you really want to run each tent well you should definitely run 2600 in each or maybe get some of those stands with the 2x4 as the support bar in the middle and you attach a mover to the 2x4 and just use 2000 in each tent.

If you want those amazing nugs i would go with the 2000 with a 6 in the middle of each 1000

you dont need 2600 watt's in there bro that is for absolute optimal( best )
it's not a have to..set in stone..or anything...
2 x 600's will jam a 5x10 fairly well...grow nice big bud's that are sticky and have lot's of tric production.. i have a 5x7 and it was only lit with 2 x 400watter's...pullin pound's bro..hid is way more intense than sunlight to MJ...so no you don't need 2600 watt's to grow it indoor's..it's not a "need" it's optimal..
now i bumped it up to 3 x 400watter's for 1200 watt's in a 5x7 and expanding to a 7.5 x7.5 area...using the 3...



this is only one corner if my flower room now... for example..lol
these clones are all afghan kush and LA woman...they were all flowered at the same time when they were only 6-7" tall..
there not even known big bud producing strain's but you can see the bud's for your self..these are lit under 2 of the 3 400's...that's it!
a proper soil mix and feeding reg will go a long way bro...in hydro, it will be proper feeding , flushing , and ph control...not much to it really..

When you use 2 light's instead of one..your working against the inverse square law buy supporting light in a wider area from 2 light sources spead out rather thjan just 1..like a 1000 w hps for example..
to get it to cover more area we raise the light, the hood will only alow so much of a foot print..
this is why using 2 600 watt light's is way more efficient that 1 1000w..your blending two seperate foot print's into an area rather than only 1..thus working against the inverse square law..

hope this help's cheer's!:wave:

I run 2k in 5x10 tent. I definitely wouldn't run 600s, thats a 5x5 footprint each, and they will penetrate more.

This is exactly right. Some people go only by what the "formulas" say. Think about it, a 5x5 area is perfect for a 1k. Go with the magnum xxxl hoods for the best footprint. Please trust me, I have intimate knowledge on those 5x10's. If you grow scrog consider 3 600s but 2600 watts? good luck keeping that cool and getting about a 5% higher yield. not worth it imo.


2k in magnum xxxl hoods ftw.:tiphat:

This is not true. Everything else is good, but hps light is NOT brighter than the sun! Never, ever.

"Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux, which includes infrared, visible, and ultraviolet light."
Wiki...
just to quote something, but this can easily be achieved with hid lighting..
HPS are also 70% more uvb on average than sunlight and red spectrum's are more intense than sunlight when using HPS lighting..

There are plenty of other things I could put here to prove my point that you'll never acheive the suns power indoors but this is a thread about tent size.


2k will do you fine

2k is plenty 3 600s will give you more. we have done tests side by side same strain. theres my 5x10 packed seaofgreen from 2kw

thanks for all the good info folks, I think ima go with 4x8 and stick with the 2 600s and see what happens. thanks again!!!!

not according to my light meter, it even read's higher in my grow room than it does outside..
it's a fact..
hid has come a long way..and i can do the simple math on sunlight...
93 lumen's per watt on average ..so for every 1000 watt's the sun can produce it's only 93,000 lumen's...
1000watt hid...hmmmm 155,000 lumen's...and it is all about lumen output..
it's a measure of light intensity...
that's why 600's will alway's be a more efficient light than a 1000watt and the more lumen's a hid pushes the more $$$$..
so ya the lumen output is key...sorry bro but this is dead on..it even tell's you this in the lighting section of just about every good grow bible out today.

"sorry bro" but you are totally wrong because you forgot to account for #1 coverage area -- the sun is an ambient light source that is hitting the plant not only directly all across its surface, but also indirectly as reflections from every single object within visual distance. #2 you also forgot to factor in the light spectrum; the sun has a FAR greater and stronger spectrum (in all areas including where it counts for growth) than any indoor lamp.

when you add it all up, the TOTAL amount of light hitting your plant in an outdoor setup with good sun visibility is FAR greater than ANY indoor grow.

no the sun has a spectrum of around 6400k it's been proven..
hid increases spectrum in area's where red's are needed...
3000k-2400k spectrum for example..hid is way more intense and has even been proven to have 70% more uvb than sunlight as well... and i did factor in light spectrum and uvb go back and read this thread you will see i did in previous post..
clearly..
and yes the sun has more coverage area, but you grow in a 5x5' area outdoor's with a particular strain and i will go grow that same strain in the same space, under hid indoor's...same veg and flower times mind you..and let's see who's got the dense nug's and better growth along with tric production..then tell me i'm wrong ok..

i understand what your saying but i'm the only one who's quoted fact's! the sun is brighter i never said it was not, but hid is more intense..! so yes the sun cover's half the world but at only at about 93 lumens per watt..were as hid , in a givin area is proven way more intense!
yes the sun may have more coverage area, but when you factor cloud cover,rain,storm's,smog etc..
you rarley ever get a constant measure of light coming from the sun, as were hid you have that same intense light 24/7 it does not have these variables to factor in..also.

so your calling my light meter and i guess all math a lier?

let me stop you right there. first this very first statement it is obvious you have no idea what a light spectrum even is, and are thus completely unqualified to participate in an argument on this subject. please do some more research. hint: what is a nanometer, and how does it apply to photons in the visible spectrum?

by the way: no, HPS does not output UVB light AT ALL (nor does MH) because ALL UVB light is filtered by the bulb glass. please educate yourself before attempting to argue in subjects you clearly do not understand.

I really hope your not using a cheap light meter. Like one that's under $1000? Thought so.

man did you seriously just even say that? lol
why would i spend over 1000$ for a light meter?
why would anyone?
i'd rather buy strain's, lighting, vent, nutrient's ..lol
to spend that much on a light meter is silly...really man...silly..
you could buy a used car, and drive by the guy walking around with the lightmeter in his hand...lol
And the math is still there, you guy's are saying math is incorrect..on average studies show by scientific research that the sun is apx 93 lumen's per watt...
about as much lumen output as a 600..actually to be exact, 2,000 les than a 600watt hps...
math does not lie!

ginger,
And not all uvb light is filtered through glass, that is crazy..there are lot's of lighting choices out there that offer uvb..
yes hps and mh...
actually there are debates all over the net right now on mh vs hps and uvb...
some are claiming that a mh conversion or reg mh bulb has more uvb than a hps, thus better for flowering, due to mj's use of uvb to help create thc! google it! lot's of stuff on it!
so i guess your weed lack's a lot of thc then...lol

it has also been proven over and over that plant's grow about twice as fast under hid than outdoor's, but i guess that's cause the sun is more intense right!?...
geez really? i mean guy's look at your plant's, do some side by side study instead of bookworming your way through mj forum's...actually grow it...then tell me..
besides you guy's are hyping 1000watt light's in this thread to, what a waist of power and money..
funny though he got 2 600's ...lol why? because there more efficient..everyone know's that...pretty simple math on that to...
so all you guy's are off...
