2 1000 watt HPS lights, how big of a room to frame up?

Making plans for a room being built in a shed. The ceiling is about 6' 6", I might be able to cheat some more space by cutting holes in the floor for buckets to drop into. I should do this to give my plants another foot to grow, right? If you guys could build a room with these 2 1000 watters what would the dimensions be, with both lights in the same room. Thought about two rooms but that might be to much for me, seems a lot more expensive than just going with one room. This is my first attempt to grow inside, I have no indoor experience at all. So any suggestions are welcome. I live in the SE and it get's hot and humid here, any idea's on cooling, I have a little money to throw into the room so a window unit a/c is what i'm thinking.

5'x10'

5x5 is a good coverage area for 1kw

I've seen a 1k light cover a 6x6 with outstanding results. just get a good bulb

Your looking at a 4' x 8' area. Each light (1000w) covers a sq. ft. of 20.25 which is 4.5' x 4.5', which is 1 (1000w) light. Times that by two = 4x8.

Beat it spammer, were not going to your website to watch midget porn.

id go with 5x5 per bulb personally OP, with some xxxls or raptor hoods.

Id go with a one 5x5, and grow vertical with a screen around those 2 bulbs stacked. Dont have to pay for hoods. 2 Ballasts, 2 corded sockets, a fan and your ac. Done.

Pics or it didnt happen lol
this is kind of a tough set up for most guys and he said somthin about a 6'6" height restriction.

I would go do 3.5 to 4 feet square for max yield per 1000 . 4 med size plants. per lamp . light would be no more then 2 feet away. cool hoods.

6'6" should be fine on heigth. Ok maybe not for full sativas. but indicas should be good. As for pics, just go over to the vertical forum. Lots of peeps doing this.

Horizontal is not the way to get max yield. with a hood your growing on one flat surface. Just my 2 pennies.

it hasn't happened yet, but it's in the works. I'm a electrician by trade so I should be able to handle it, I hope. I don't know about the aero thing I'm going with ceiling mounted lights, from the sound of it I'll frame a 5x10 room for it. How about my height situation, u think I'll run up on a snag? I'm thinking about cutting the floor in between my floor joist to add at least another foot, being that the buckets/pots will be recessed in the floor.

Sounds good, but sounds a little complicated, I will check into that type of design (vertical).

I guess all this for me is subjective. I used to use a T5HO 8 bulbs for flowering. 4 plants, harvest 1 every 2 weeks, each plant gave me just over a zip. And for just me that was all i needed. Guess it really depends on your goals. Im changing my shit around to a vert 600 in 5x5x7. Have 3 others im supporting their medicine on.

vertical growing at its best

Heaths shit is pretty dope for sure. Ive always wondered how that would yield if he did some deflorification to it around week 4.

This dude is correct. People always talk about what size room they would build for a 1000W HID. 4 plants under 1 1000W HID is great. I have seen growers do this. Plants get really good light penetration which leads to bigger denser buds almost all the way down the stalks. As far as size of room goes most people say 5x5 or bigger which is correct. But that is to distribute the light across a bigger area. A smaller area with 250W per plants as long as your PH, PPM, Nutes are all dialed in is really the best way. Depending on the strain you are using with that amount of light you would be able to keep your plants pretty short and bushy in a smaller area as you said you have only 6.5 feet of headroom. Kind of like compacting you plants with light if that makes sense. But this will also partially depend on strain used as well.

It really depends on how you are growing. Do you plan on growing outright normal term plants without LST, Scrog or the alike. Planting seeds and letting them go feeding all the way to harvest without any training is when you would want to use the 4 plant under 1000W. I have seen some pretty big plants like this. If you were going to scrog or anything else you want the light to be distributed. as you really only want the light at the canopy anyways. But either way 1000W with 4 plants or scrog or the alike will yield around the same. I know some people will disagree with me on this. But if you compare. They are pretty close to one another as far as yields go. Doing the 4 plants per light gives them room to grow as well as saves you room. You wont need as much room say if you went with a 5x10 with the plants all crammed in there.

How many plants are you planning to grow anyways. Or did you want to grow? Do you have the room for 5x10? are you looking to to do a scrog, SOG, or anything like it?

Personally I would go 4x8 with a 1000W spaced right so each light covers a 4x4 area with 8 plants. 4 per light like Kinddiesel stated.

Another thing is though. Kinddielsel stated cool hoods. This setup would work wonders but you have to be able to cool it. What kind of ventilation are you planning on using?

Oh and so you know I was not talking about vertical growing either.

Its always been the ventilation that gave me pause. seems to me that whatever you spend on hood/ballast/bulb your going to damn near spend that again on ventilating the heat/scrubbing odor. seems like a lot of extra expense cooling the room and hoods. imo of course.

So what is your solution? Just curious what you came up with.

Running barebulb. I have a 40 dollar fan blowing up at the light, an ac unit to cool the room and a ona block for smell. I did already have a A/C unit for the room. So my cost was 1 ballast, 1 bulb, 1 light socket, and i bought a Lasko fan with remote. 320 bucks.

If you build a room w 4x8 or 5x10 or whatever you choose you need to be able to get all the way around room so a 4x8 room would actually need to be prob 6x10 so you have 2 foot all the way around plants. Also you need room for a reservoir dehumidifier etc so you need more room then a 4x8-5×10 etc. You can place res outside of room but then a res is visible in shed etc. Look at all equipment you need draw it to scale and be realistic. You might think a 1 ft walkway is enough but when plants get bigger that foot is no longer . My room is 7ft wide x 12ft long and I have 2ft on one end of room and 3 ft on other with no walkway between or around plants I have 16 in 5 gal buckets. I would not cut holes in floor to drop buckets into either cause you will need to move them around. Also think of watering if you water you dont want water under shed to rot shed out etc. Do alot more research your missing alot of important areas and questions that need answered. Just being honest. If 1 plant is 1.5ft in diamrter 2 plants is 3 ft etc. So 4 plants is a 3x6 area. As you know plants will be bigger and smaller so make room much bigger to allow room etc.

i have run 2 1000 w in two different room both with height issues because of where i had to build the room. i went 8x8 so that i could walk around the outside of the plants to work on them. the height is only an issue if u let it be an issue. i would suggest you scrog or otherwise tie down which by the end looks like u sprayed your room with silly string. as long as u keep an even canopy you can really maintain the height, and i only say this because i have done it for years now.
