Help design my grow room

I have a 8’ x 8’9" x 8’ room to start a grow room in. It’s a blank canvass that I can do with as I please. I have been doing homework on it for several months, but was hoping for some advice on the layout. I plan to start out with several feminized plants and some auto flowers.

For equipment to start I have:
2 - 600 watt HPS
1 - AC Infinity 6 inch inline exhaust fan
1 - 2x4 grow tent (was ordered before I decided on room)

I can legally grow at the same time 12 flowering plants, 12 plants in the veg. that are at least 14 inches tall, and 12 clones or seedlings.

I think the exhaust fan is too small for my area. I plan on adding a 3rd light in the future, and I have allowed for up to a 12 inch exhaust fan to eventually replace the 6 inch.

This is my first ever attempt at either a grow room or a grow. ANY help on the layout or equipment would be very welcomed. I do have some additional funds to start the room. If it was your room, what would you do?


I think you will be fine with the 6 in for a 2x4. I have one and it sucks the walls in on low. Also would do only 3 ladies max at one time

What I plan on trying is the SOG on the regular plants. I won’t be using the tent unless needed.

I should add, I plan on growing in soil until I learn a better way.

Very nice start. Welcome to ILGM.

I like the idea of keeping mother plants in soil anyway.

You won’t regret having that tent, and you may decide you want a few more.

Can you describe the room more? Do you know how many power circuits run to the space, and what amperage they are?

How is the room currently heated and cooled?

That’s about as awesome as it gets. You won’t know what you don’t know until you know, you know? Once you get some plants going in there, you’ll be able to figure out the fine tuning, timing, etc. Homework is good! Do lots of research, ask lots of questions, and don’t worry! You’re in very good hands here. Lots of pros already on this thread. Welcome to ILGM, @letitgrow!

Here’s my spitball: I’d figure out a way to section off the room into two sections, either another couple, larger tents, or a temporary wall covered in panda film. That way, you can have a separate flowering section that you’re constantly rotating plants into. That would take a lot more lighting, if you plan on using the entire room. For now, though, I’d put one light in the tent, one outside it. Then you can have them on two different schedules. I’d put the younger plants in the tent, since they’ll take less space. Then when you add the third light (if you want to go with all HID) you could make your flowering space larger. The only issue there would be timing. You wouldn’t be able to go in other than during “daytime” for your flowering plants. Unless you run all autos. Then you can just light the hell out of the entire room and go for broke filling it haha!

I know the guys with more experience in this stuff will give you great advice on the specifics. I’m just the pothead welcoming committee. :v::joy:


I have an electrician helping with the power needs, so I’m covered there. I can do with the wiring anything that would be needed.

The room connects to a larger living area. Plan on venting and taking fresh air from living space. Which is central heat and air.

At the current time, the room is just a box with unfinished inside walls and no window.

That’s excellent.

What separates the grow room from the living room? I’m just trying to brainstorm how you might draw air in from another space. What’s above and below your grow room?

I’m going to bed in a little bit, but I’m happy to continue talking about this later. Check out this other thread where another grower had similar questions.

I think I was a little confusing on my last response. I will be venting the grow room through the ceiling and out the roof. That’s where I am allowing myself for future expansion to a 12 inch fan.

Above the grow room is an attic. Separating the grow room from the living space is finished drywall on the living side and bare 2x4 on the inside.

Thanks for your help!

I’m having a little trouble picturing it. How do you enter the room? How are you planning to pull air in from the occupied space? Sorry if the answer is obvious. Climate control is just really important.

Enter the room through a door from the living space. Was planning on putting a vent between the room and living space to draw air from the living space.

And climate control is one of the areas I really need advice on. I’m having trouble wrapping my head around how to control the climate in the grow room, if the air is constantly being exhausted from the grow room.

Go with a 4x4 instead of a 2x4 you’ll tah k me later

There are window duct kits. Use inline fan to duct from one window to another. Then use another duct pulling air out close to your lights. Would be nice if you had a privacy fence or hedges.

What about through the attic? Just cut a couple holes.

The space in question doesn’t have a window.

Oh shit yeah forgot. Well that sucks. If I were you and had the resources you’re saying you have I’d be installing some serious stealth ventilation from either the ceiling/roof or right below the soffit on the wall, high up.

How to control climate. Or atleast something that can help

@letitgrow is the space going to be used for drying too?
