What size of area do hps make useable?

[KP2]

Ok scrub go look at my january album.
lol never used a hps...rofl

Thats ONE 1000w hps in a 10x8x8 room.
Get good.

AHAHAHAHAHAHA!

i'm sorry, hopefully you'll have a better outcome this time. this is a picture of sog plants. that big one was 4 oz dry as a bone. there were 34 more plants under that 1k, 2 more in the room (5x13). couple other pix for you too....

get good . smart ass.

 

[fureelz]

uhh awesome...i can do the same thing...if not better.. good day

 

[Jtoth3ustin]

*drool..... purple... Pe@ce.

 

[KP2]

uhh awesome...i can do the same thing...if not better.. good day

and with only 1k, right? pix would help, your gallery is quite lacking.

i'm done, toodle loo!

 

[fureelz]

Eh no thanks, I like to keep posting pictures to a minimum. I don't flaunt anything to degrate someone else, but you're more than welcome to stop by.

I see many grow rooms in my travels and I also see lots of bad practices and nasty looking canopies. I thought I would try and shed some light on the problems I see popping up the most.

#1. Improper use of lights!

It is common for growers to want to group all there plants under the hoods but this can cause a few problems. Many Sativa varieties will fox tail and form dready buds if the light intensity is to high.

Your wasting space if your not covering 6x6 with a 1000 watt hood!

Indoor Theory​

Lighting​

Lets discuss a few ways to construct a indoor grow room. According to your local laws, each state has a different limit of plants that can be grown in a space. I find it best to always have less plants budding than allowed so we will be learning to keep our plants in the vegetive state longer than normal all the while training and shaping the plants for maximum production indoors. In my youth we would run as many as 40 plants under 1000 watts in a 6x6 area. Now we design bud rooms to run between 4-6 plants in the same area with the same wattage lights. The yield is very similar and the main difference is the amount of time the plant is grown under an 18/6 lighting schedule. The plants are topped and shaped to form a wide bush that will finish with multi-headed and at a height of around 5-6 feet. Think of each area covered by a 1000 watt light as a 6x6x6 Cube that you are going to fill with Cannabis. By using 3 separate areas designated as Cloning area, Vegetive area, and Budding area, you can continually harvest medicine every 60 days.

We are going to use some firm measurements in this teaching example but almost any configuration will work that allows the three areas to be constructed. Every light/bulb has a foot print. This means the area that can properly be covered for maximum production.
They are as follows
1000 Watt Hoods…………6x6
600 Watt Hoods………….5x5
400 Watt Hoods………….4x4
250 Watt Hoods………….3x3

i got my 1000W in a 4x4 room.... im getting some light problems.. i think caused by the light... i have it about 3-4 foot away.. im realy perplexed...Pe@ce..

I agree but the best growth will be under a 1000w is around 4x4 room if you have a 6x6 room you will grow more but then it comes in to plant numbers 6x6 room will take shit loads of plants in SOG. work on 50 watts per sq foot and grow a worth while crop with sold buds than harvest a grow with fluffy buds and lots of stalk.

there as been many tests done on cannbis and what covarge lights = yeild and the more light you give it the more it will yeild up to if i remmber was 75 watts per squre foot, but 50 watts per sq foot of area in sog yilded the most bud. the tests were done on overgrow where the members came in the millions every day from all round the world if you never had the privalage to be a member of overgrow then you will not understand where im coming from.

yea i guess we are gonna just have to disagree here....

 

[fureelz]

do what works for you...I am actually moving to 1200 watts but my 1k watt in a 10x8x8 room works just fine....im out of aluminum foil, can I use a mirror instead...how about some cheap ass white paint?, laff.

 

[fureelz]

oh and my awesome light is EXACTLY 18" away from the top...lol..KMA!

 

[9inch bigbud]

yea i guess we are gonna just have to disagree here....

have you ever grown under a HPS? it looks like you use CFL's the post about 6x6 room is copy and pasted iv read that from somewhere else before. proof is in the growing i use 600s and 1000s and know what area they cover to get the max yeild out of them. A 6x6 room is only 27watts per sq foot the rule of thumb is 50watt per sq foot. o.k 27watts will grow a 6x6 area but it will not grow more worth while buds than a room that is 4x4 using the same size lamp, trust me my 1st ever grow room was 8x8 if you leave enough room to walk around it about 6x6 most of the plants were tall and lagy because of lack of intense light.

150/175 watts covers approximately 2’ x 2’ area
250 watts cover approximately 3’ x 3’ area
400 watts covers approximately 4’ x 4’ area
600 watts covers approximately 6.5’ x 6.5’ area
1000 watts covers approximately 8’ x 8’ area


from sunlight supply

i belive you need more and will always give more but thinking outside the box can get you great yeilds and can fuck you aswell.

exp and see what you like

that is maximum light covarage the rule of thumb is 50watts per sq foot. "TAKEN FROM OVERGROW" where tests were done on light = yeild fuck what some hydro shop tell you all they want is your $$$$

i agreed then and do still now

but every garden is diffrent and can not be held to one starderd

1 sqm is 11 sqft and 400 do them just fine

i had a flower room that was 3'x6.5 whitch is 19.5 sqft time 50 watts by your set parimter would be 1 1000 watt bulb where i belive 2 400 were the better choice at 800 watts where as if it was s.o.g i would have went whith 3 250 maby

i say there is no starderd but the ones you set for yourself
right now i am blooming in a 4'x8.5 whith 2 600's and am debateing on switching to 2 1000 or adding 1 more 600

not trying to argue just point out there is more to good growing then fourm reports and test.
i would be tempted to belive 80% of growers have no clue what a fourm is.

on a side note 50 watts a sqft is weak get it up to around 75 and let your bitchs bling

thats what im saying rule of thumb 50w per sq foot should be the minumum the more the better.

i dont know if you ever went on overgrow? some of the best growers i have ever seen on the net used to go there i think everyone who grew weed used to go there? LOL. you would find growers who were fannatics who would do tests with scientific results from everything such what light was the most efficant to side by side tests on nutes/ bosters just about everything to do with growing was looked at and fucked around with in experiments to try to tweek the grow room to the max.

 

[fureelz]

yup og was the shit.

i would only go by watts psf with cfl =... lumens are the way to go with hids and i do use hids and have been for 8 years. and i know ppl say lumens vs par watts thats all bullshit lumens are what we mesure the sun with and what we mesure our grow lights with, there is no reason to have a light brighter than the sun at its peak. you use your first grow as a comparison maybe it wasnt your light but you... it was your first grow thats silly there is no need for a 1000w in a 4x4 room. i could see useing a 600 but no more it would be a waste you do what you want but i know how to grow and i know how much light is needed and have been getting great results for a long long time... you speak of your first grow and try to use it as an example. i cant remember my first grow it was so long ago. i didn't come here to argue i came here to get the right info out.... 3x3 room with a 400w and a 600w in a 4x4 is all i would change about als post that i copied over to here and al does this shit for a living and has been for a long time so he would know he has seen many grow rooms

5-7000 lumens per sq ft has always and will always be the correct answer maybe up to 10000 if you add co2

i dnt care what everyone says thats what you need and what works any more is a waste of money and energy

your rule of thumb stinks like its been in a dirty anus

Overgrow GrowFAQ's http://www.drugs-forum.com/growfaq/GrowFAQ%20Basic%20Topics.htm

A very general rule of thumb is that your garden needs 50 watts of HID lighting per square foot of illuminated area. This rule ignores the shape of your garden, so the following is really a better guide:

A 250 watt HID will illuminate a 2' x 2' garden.
A 400 watt HID will illuminate a 3' x 3' garden.
A 600 watt HID will illuminate a 3.5' x 3.5' garden.
A 1000 watt HID will illuminate a 4' x 4' garden.

From Jackerspackle, here's a different take on watts-per-square-foot/meter (WPSF).

WPSF assumes that the bulb's intensity is equal over the entire grow area.. in other words each square foot/meter receives the same number of lumens. But in reality light diminishes rapidly the farther you go from the bulb (1/4 the intensity for each doubling of the distance). So each bulb has a limited range, beyond which you do not have good growth.

For example, a growspace that's 2 x 10 feet would require 1000 watts if you go by the 50 WPSF guideline that's commonly mentioned.. But a 1000 watt bulb only covers an area about 5 feet across - meaning the edges of your garden will be dark.. A better choice in this case would be three 400s or two 600s.

Another problem with WPSF is it assumes all bulbs have the same intensity. But 1000 watts of HPS is not the same as 1000 watts of fluorescents or (yuk) incandescents. Fluorescents have their lumens spread out over a long tube and are therefore dim.. incandescents have the wrong color spectrum and are also dim.

Nor is a 1000 HPS the same as four 250 HPSs.. 250s don't have anywhere near the intensity needed to penetrate thick canopy or tall, bushy plants. (Don't even think about growing meter-tall plants with a 250.)

I could go on, but here's a basic guideline for lighting a growspace for good growth using common HIDs:

WATTAGE -- COVERAGE
1000 watt - 4 to 5 feet across (1.3 to 1.5 meters)
600 watt - 3.5 feet (1 meter)
400 watt - 2.5 possibly 3 feet (.8 to .9 m)
250 watt - 2 feet (.6-.7 m)
175 watt - small, less than 2 feet

These numbers assume you have a good reflector around your bulb and also reflective wall coverings. You can increase the figures a bit if using multiple bulbs, due to their overlapping effect. You can also increase coverage using a light mover...

I know this won't put to rest the old WPSF idea, but i hope it shed some light on the subject.

above is taken from overgrow FAQ and is that is pritty much the holey grail when it comes to growing.

here is my 4x4 room with 1000w lamp this room yeided over a gram per watt

and here is a room under 2 x 600w each light is covering 1m x 1m
