HPS Lamp Question..

Hi everyone..
Starting to set up a grow room, was thinking of 2 1000w HPS lamps to start with, any ideas on how many plants that would cover, or am i better with one Metal Halide & 1 HPS ?
Thanks in advance for all the help :p :thumbsup: :)

It's quite an advanced set up to just start off with, check this guy out:

Hey Faithless, thanks for the link, i'm thinking of getting the lamps as i start to basically save myself money in the future, meaning buying one set of lamps only to buy those later on

1000 watts wil cover alot of space and 2 even more, if ur space isent huge u dont need that much watage it would get very hot unless your space is large anough and well ventalated, get a HPS ballas and 1 HPS bulb and 1 MEtal Halide both of the same wattage you can run your Metal Halide in the same ballast as the HPS of the same wattage.

Hey Bongo, the room we will be usin is 11' x 12', and i'd say about 9'x9' will have plant growing in it, would the 2 x 1000w lamps still be too much?, i just don't wanna buy too low a wattage only to go out and buy more, as you know they arent that cheap..

9x9 would need about 4 to 5 1000w's to get decent coverage with the 50W's per square ft rule of thumb.
Any how, buyying 2 1000w's the lights would be the cheapest part most likely, after hoods, possibly air cooled or cool tubes, substantial inline fan, scrubber, possible AC unit and other misalanious items, nutes and so on you would be thinking that the lights were the cheepest part of the set up.

hey j.a.b
my spot's exactly the same size as well as the area wanting to be actually grown , 9 x 9 , in a 11 x 12 room . i use 2 -1000w. hps . start to finish and have no problems . i use 6in. cooltubes and a damn good 6in. hurricane fan to draw air from outside the room thru the tubes and back out of the room and don't have any heat issues . 78 deg. n balmy . i only do 8 or less in waterfarms to keep plant count down . i veg for 4-6 wks. depending on strain , i'm mean to em to, l.s.t , top em , pinch em etc... on average we can net 10-17 oz. per girl . it takes a lil longer this way but i find it's alot less work n upkeep to only care for 6-8 girls . but i'm not looking to supply the masses .lol . i'm a med user and only have to do it once a year .
wise move thinking like you are w/ equipment etc... the shits expensive. to start out in a lil cabinet n find out "damn this is easy" and want to expand and have a 250-400 watt light that can only penetrate a foot or 2 at best .you'll end up wanting the 1000's belive me , once you've got the bug look out .

peace

Thanks bluebear & xcrispi for the input. We've got about 600GBP/1000USD to kick start a growroom, we've priced up other stuff, extraction, ferts, fans etc etc etc, it's just this lightin and the different opinions on ferts that's crackin my head up. And to finish of this cold horrible day, i have just crushed one of my little seedlings trying to take a picture.. gutted :(

I think your best bet is 1 600Watt MH and 1 600 Watt HPS....much less heat than a 1K and correct me if I'm wrong anyone but I believe the 600W HPS bulbs have the most lumen's per watt. If your needs are greater than that then go with the 1ks but you better have a good fan.

take it from me J.A.B. your going to need alot more money than that for your room. 1000USD will barley cover your light costs. i thought when i start seting up my room "im not going to spend more than $700 on my room since this is my only 2nd indoor grow..." than it was like "no more than $1000" and now im at around $1800+ for everything and have about a $2700 room (i barrowed alot of stuff luckly). if your going to do it first set up your ventilation, light proof, bug proof, reflection, and every thing you will need for your room then buy your lights and add as you go. it sucked for me having to add on to my room and drill holes in my wall when my room was full of plants. one of my plants died due to it. it is very possible to add on as you go but it sucks having to wait from pay check to pay check to get stuff your ging to need imidiately. ~ I would go with 2 1000w switchable ballast and start w/ metal Halide and switch to HPS. then add CO2 or sulfur vaporizer or humidity controllers, ect. and my room which is a little smaller barley fits my 17 plants so i wouldn't have more than 20 if i was you. the amount that you yeild will justify your cost 5 times over and $1800 out of the $2200 of stuff you can reuse. make sure you do it right or you might lose all your yeild; it happened to me last time. thats why i invested months and alot of money to do it right.
