Grow Room Dimension Advice.

Greetings,

I've done this for about a year and would like to build a new room. I'm looking for advice on the optimal size. I'd like to arrange my hoods in a row the long way, so the venting is a straight shot out to keep things cooler. I'd like to have at least 9 plants at a time with 3-4 weeks veg times before going in. Do I have enough power to run 9-12 ~4.5 feet in size?

Thank you for the advice.


Equipment
3 x 600W HPS
3 x 19"x21" air-cooled hoods
1 x 8" inline fan
1 x 10" oscillating fan
(Mylar for walls)

dont for get the ac and dehumidifier.

6'x24' would be my guess.

I run a 14x7 flower room with 15 plants. Tryed my 3 lights that way but lights wounding cool even. Last one was hot. Almost like I wasn't cooling at all. Here is a vid I took of what I found to work best. Just need a filter on the intake to create backpressur so air flow is even thru the lights. And I wouldn't use your rooms air for cooling lights. Just have a second fan running a filter.

Watch this vid and check my sig. Posted alot of photos.

Greetings,

Thank you for the advice fellas. I guess I should provide a bit more info.

My old room was 8x8 with one 600w HPS. The temperature never got above 72ish, without air cooling the hood and humidity wasn't a problem either. In my 11x11 room right now, two HPS brings the heat up to about 82 max, again no humidity issue.

I guess I should debate if I want to stay in the 11x11 upstairs or move back downstairs. I want to boot up this third HPS a.s.a.p. but I also want one of my spare bedrooms back. Plus, in the basement I can put the room back up right next to the panel, which is way better and cheaper than the 40 foot run to the current room.

Any more opinions?

I'm not feeling to have a small ass room that gets hot. If you ask me, using an a/c and dehumidifier in a non-CO2 supplemented environment is the stoner way out of building a quality functioning garden.

Thanks.

what does using an ac and dehumidifier in a room without co2 have to do with anything? that makes no sense. take a look at my room in my thread, perfectly sealed, no odor control. and i didnt run co2 for 2years in it and still pulled 30+oz every three weeks. not bad for a stoner, huh? its called controlling the environment, what all indoor growers should thrive to do.

Sorry if you took that to heart superstoner1.

I was implying that I strive to have a garden that systematically controls itself. And so far my last two have just fine, and I know plenty of growers who do the same.

To me, unless your house is too hot and/or humid to begin with, or if you run CO2, there is no reason not to use an outside air source to control humidity and temperature. I don't see a reason to waste the exhaust air either. That air can really help suck moisture from a house during the summer and help keep a space a few degrees warmer in the winter.

A friend runs a 30x20 room with 15k watts. No air conditioner, no humidity control. It's well thought out and highly efficient. Of course he could have thrown two huge a/c's and dehumidifiers in there. But like I said, that is the lazy way. Like another friend who has a 12x15 room and 6k watts, two dehumidifers and a/c's. (and CO2) Their electric bills are almost identical and I'm sure you can guess who produces more. No one ever said it didn't work or that it was wrong - please don't take offense.

It would be nice if I could use my outside air to control my room. Unfortunately it is not a option. It's ether hot 115+ and 10%. Or it's cold. 30f with 80%. so I can't realy do it. It's not lazy don't have a choice. Many others are the same. I'm working on ideas for my next room. Water cooled.

Those would be the underlying circumstances I mentioned! You need that stuff then no doubt. So I guess I spoke wrong, glad we are both on the same page now.

My basement is a pretty nice spot as far as environmental stability. It does need a dehumidifier during July/August, but the majority of the time all the windows bring in and pull out the air quite well. In the winter you just need a fan cirrculating the air around the room. My forced heating system has two ducts down there, I tape off one as not to waste and it stays above 65 all winter. Because of that, my winter grow was fucking gorgeous yellows and purples and oranges.

So what do you think Warlock, maybe I should just go with the 8x8 again?

I would. Sounds like you want to go that way but your asking us to talk you out of it. You already stated temps where better and easyer to control. Plus the larger one takes up a room in the house that you could use. So a 8x8 in a unused area or a 11x11 in a space that could be used. Bigger area bigger plants. But a 8x8 would easily house the 9-12 count you want.
