my blueprints, where should i put my lights?

picture?

 

depending on how much you want to grow you could use 250w's 400s or even 600s. id stick with the 400hps's tho.
you can pay anything from £50 to £250 for a 400 depending on what you want and how well you shop around.

 

2 x HPS 400 = 250$ x 2 = 500$

7 x CF and fixtures = maybe 50$ tops.


ill bet a constant production stash of 4 oz a month
4 oz x 400$ oz = 1600$/month.

 

oops

forgot about the rotation

 

if your gonna mount 2 400s to cover a 11foot long space then atleast mount them with the bulbs facing across the grow not along the grow like you have in that last pic or there will be some real dull spots in that grow. even then 5.5ft is a long streach for a 400. imho 3 or 4 250s will do a much better job as the grow is only 2ft wide. and if your gonna use 250s then why not throw 1 in that scrog aswell, would meen you having to carry less spare bulbs and ballasts if 1 did go bad on you.

rotation along the long grow is a good idea.

 

what i ment was...

if u set it up like i had it, thru a rotational system u could harvest about 5 plants a month in there.

here is maybe a better explaination of what i was thinkin...

use the small square to do all ur 'veg'in room'.

MH or CF or someother kinda fluro system. then that compartment is sealed off light and on 24/0 or 18/6 forever. once a plant has gotten to a 12" height, it moves into the 'flowering room which is ur longer room.

as ur plant matures it moves down into ur room closer and closer to the fan. why u ask? do u want ur stinky thickly leaved plant closer to the fan then the airy more spindly plant nearer the door?
so ur air comes in thru ur airy unflowered plants and gradually brings thru the stink til it gets outside. (im assuming its venting to the outside).

 

so lets do a pretend time line for ur 4oz a month system u gots goin here. fyi, u could easly do more if u were so inclined with as much room as u have.

u seed 10 seeds at a time in veg area #1. in about 35 days, those plants could get to be about 1 ft tall, which is large enough to go into the flowering room.

u should be able to weed out the males within a week of flowering cycle. one of ur jobs is to get good at that and after a few grows with ur plants, ull get the hang of that pretty good. 9/10 times i can tell a male/female even before flowering bench.

u then put the plants 5 at a time (or 10 and weed out the males very shortly as not to take up space, unless ofcourse u wanna make ur own seeds which i would highly recommend. why pay for it if u could get it for free?) into the #2 area which is ur newly forming flowering plants. these are the ones that u need to take care of. prune, tie down, whatever ur gonna do to em to increase ur harvesting techniques. this #2 area is 12/12 hps and CF filled lighthouse of lumes. i want this area to be glowing like the sun. as these plants are harvested off the back end of area #3, the plants are slid over, slowly getting older and older and more mature (and stinky) until the day comes when ur seed is now about 1oz of stash for ur pleasure.

my estimation is that u have enough for 4 diff cycles going in the amount of room that u have, maybe even 5. if ur 5 plants takes 120 days roughly from dry seed to harvest day and produces about 1 oz of stash, divide that by 4 cycles and u come up with about 5oz a month. 1 oz will be not up to snuff and some of that u will use for ur seed making. so in the end...u have 4oz a month.

ya?

 

by the way...as i read this im not sure of something.

my assumption here is that u can keep light within the boarders that u have drawn. meaning that one part can have a diff light cycle than the other part.

also...these walls have to allow for proper air circulation. exausted air goes thru the path of least resistance. if u have ur exaust fan right next to an open door...ur back part of the room isnt gonna get ANY air. make sure u set it up so that its a sort of a 'wind tunnel'. how to check is to light an insense and watch the smoke blow thru. and check around the building to where that smell is going to. if that smell leaks into ur neighbors place, it wont be long till someone comes knocking.

a chamber when u close the doors, air comes in ur veg area, circulates thru the room and spews out the end of the flowering room. also allowing for no air or lightage escape.


also, 3 gallon pot is my perfered soil holder. 5gal too big. and if u are gonna clone, 3 is plenty big.

as to lights? i agree with thug, more da better. easly u could do 4 x 250's in the flower room. but i dont agree to put HPS in the veg room. i think its a waste of $$$ for the results. MH yes, CF's yes, HPS no. CF's are cheap to run and easy to use and cheap to buy more with. if u get 3000 lumes per cuft, ur good to go. however many u need to get to that point is up to u.

 

hps = reds which are most used in the flowering stage.

mh or CF's = blues which are most used in the veg stage.

also, hps puts out alot of lumes. u dont need that many to veg it. u could easly grow all ur veg area with 250w MH or maybe 200w (8x 50w) of cf's put together.

but there is no doubt that u need HPS for flowering or dont even bother.



as to how many HPS? ive done a little calc work.

11ft Lx 2ft Wx 2.5ft H = 55cuft. 55x3000 lumes for max growth = 165,000 lumes needed. with mylar and good lighting placement, my guess is u need about 125,000 lumes.

400w = about 50,000 lumes ave thruout the life. so u need about 1000 watts for a full grow. 6 x 150w is close.
900w of HPS is gonna be hot. and i would supplement with CF's like blazin's grow journal if ur gonna try and push some serious plant growing thru this system.

again...this is pushing alot of harvest and wattage thru ur place. certainly u can scale this all back.
