Hps lighting in lrg room

Question about 1000 w hps. Mag ballast.
New grow area is 11x14 ft. How many effective sq ft will I be able to use for plants. @dbrn32. @Covertgrower.
I’m just getting things planned out for arrangement. Looking at middle of room for access to all sides. Thanks in advance.
Peace. :v:

I would think a room that size can handle atleast 3 1000w lights :thinking:

Room can handle it. My wallet won’t at this time. @Liljoe. Box says up to 8x8 but that’s a stretch isn’t it for 1 light. I’m only doing 4 plants. :v:

My buddy did 3 of my GSC clones in a 3x4x6 tent, and 1000w light, abit of height issues near end but great results. I think 4 girls would b perfect under one 1000w light

Thinking about 6 HPS in that space. @dbrn32 says they flower a 3x3 each. So with that in mind, consider that for the “best” coverage. Anything less than that, you’ll end up with a few dark spots. @Oldguy

Thanks @Covertgrower. I’ve also got a small (300 w) blurple UFO that will be in there as well for supplement if I can use with benefit ?

Throw it a corner for funsies if you want. Not necessary though. since you have it adequately covered. @Oldguy

I said what? Lol! Maybe a 315 cmh.

A fresh 1000 watt hps bulb is good for about 20 square feet. People will run them in both 4x4 and 5x5 tents/spaces. But if you’re designing a room you want to perform well I’d stick with one per the 20 sq ft. You can get more coverage out of a double light like gavita pro, they’re also quite a bit more expensive.

You say this ^ @dbrn32 I’ll just blame blue dream. :grin: swear it was HPS too though. Now I know.

Thank you @dbrn32. Where I’m only doing 4 for now with the one light I should keep it under 5x5 ? And if I put more in grow then more light is then needed.
Thanks. Just running ideas for my setup and trying to make easier for my arthritic joints. :v:

Ya, I’m sure I’ve said that about a 400. Not a 1000 though.

@Oldguy yes, 5x5 or less. And you should probably wrap that space with something reflective to keep light in too.

Kool. Was wondering about that too.
Room is going all white but thinking a closer surface would be better for reflectivity. Mylar ? Or would just all white be good ?

All white is good. Something like panda film is available on Amazon.
