Garage grow Building room need help.

Hello fellow buddah bros and girls, lol.

I have a garage my parents had in construction but was never fully insulated, and walls werent put up in the inside of the garage.
So my idea is to put up a wall to split the garage into two rooms. We are operating on a budget, so we can only really fully enclose and insulate one side to use as a grow room.

Will I be able to keep the temperature regulated properly if my grow room is finished but not the other side of the garage?

Does anybody have any ideas, tips or advice to help me build the room?

Thanks a lot.

come on guys would love opinions bump for a genuine question..=P

Are you trying to do a separate room for veg and flower? and if so one room will be insulated and the other not? Or are you going to have one room and start the seeds/cuttings and just switch the light cycle as needed??

If you're only using one half of the room I think as long as you insulate that well you should be fine. Be aware that concrete floors get very cold at night also depending on your geographoc location. Hopethis helps you out!

Check out my sig. grow. I did exactly as you are describing. It was the best thing I ever did. Hit me up with any questions I would love to help.

Well if you are in a cold area you can move your ballast inside and keep it low as heat rises, you can not have fans on your lights just have them on the plants, or if you can front the bill yuo can run a small heater the hole time and construct your wall out of panda paper .. the white inside black outside plastic .. make walls with that and pvc is what i did. you can see my link and post .. I have a small setup but im just trying to help or share info ... or and if heat is a problem and you are trying to cool your room vents circulation, airducks, and small ac units can help or maybe adding more zippers or doors... I have to do that here soon as my room is starting to heat up myself but here is my link maybe we can share some idea .......here is a pic at bottom as well

Thanks for the replies guys, I'll try to snap some shots of the garage today and post it up later for you to view. My idea was to insulate half the garage, the insulated half will be the grow room also i was planning to put up sheet rock for walls in the grow room. The other half is everyday storage. So i'll try to measure the area also. SureShot your help would be very apperciated and nice. Once again thanks all and if you guys got any other info on this subject post away!!

At my house, the garage is the only real area that we have to use for growing. While I have not yet converted the whole garage, a small portion could be very simple to create. Take a 8x8 area from your garage, and build the walls with 2x6's. This will alllow you to use 6" of insulation. I would drywall the room and paint it preferably, but there is some merit to using Poly for the walls. However the more thickness of the walls the better.

One thing to not skimp on would be the floor. You do not want the plants touching a large peice of concrete that has any contact with cold outside air as this will make for a frosty floor and no root growth. Instead plan on builidng up a floor using wood and insulating it as well.

One thing that a garage might have going for it is no ceiling. My garage has 14ft ceilings at the peak, giving me a good 7-8 ft above my grow to move hot air into. This is an advantage that some people forget with working with higher ceilings.

Now remember that in the winter it will be easier to cool with more insulation but if you ventilation is good, this can also help you keep it cooler in the summer. You might find that you will need to add air conditioning or heaters depending on your climate.

I am in the same planning stages as you and unfortunately we are both going to have to become test dummies over the summer and learn the pros/cons to climate control as we go. I have a feeling tha overbuilding ventillation will be the key with this kind of grow.

What is your guys opinion on a homedepot shed? http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100626321&N=10000003+502320+10401022

It would be way better to grow in your garage than a shed. Shed's get broken into easier and neighbors can see you going in and out all the time, and taking supplies and stuff in and out which is very very bad.

Use the garage like you planned, some thin drywall and cheap 2x4's are all you need. Build a raised floor with 2x4's also and then when it's all framed up with drywall on the outside and open framing on the inside insulate the space with spray foam including the roof and floor. (just tell the insulators it's a new home office or something.

You really need good insulation to pull this off. If you don't get spray foam then use the most insulation you can and always be sure to keep the humidity in line.
(humidity ruins regular fiberglass insulation, and it's a big problem with a garage grow.)

A space in your garage that's well insulated like that will be easy to maintain temperatures in... A small space heater in winter and maybe A/C in the summer if you need it.

My sentiments exactly.

Thanks for more replies lots goin on. Hopefully I'll get the time to measure tomorrow and post pics. Sorry guys busy week. Bare with me Sure Shot hit me up with PM on info and add me everyone.

Takes a lot on $ to start a grow. Ever grow before? What type of system? Cooling?

Still here man. Puffing away

Hey everyone sorry about the wait on pictures but here they are take a look suershot check it out.

That looks promising.
Some pointers,
You'll need a ceiling, sheet rock(best) or particle board(okay).
If you make a platform in your rafters, your ballast will be high and dry.
If you have the funds, it's a good idea to insulate the exterior walls.
The floor should be paid special attention to;
My partner has a similar room and mold is always an issue.
You see any small cracks or crevices in the floor can harbor life.
Your safest bet would be to coat the floor with some flat white paint to fill in the cracks.
Here is a DIY for framing interior walls.
Black/white plastic is what I use to seal my room off.
To secure the plastic I used a nailgun and some trim board from the hardware store.


How many lights are you using, and what size is the room going to be?
Remember to give yourself room to move in there.

I'm going to take a toke and wait for your reply.
Meanwhile...
Dude, three days ago this happened!
The cops just came!

I'm going to have a new video up later on tonight.
My girls are three weeks into flower and beautiful.

Your words bring me hope thx shot. Length of the room is 15ft and 5 inches, Height is to rafters 8ft and 3 inches, Width is 10ft and 8 inches, In veg i have t5/t8 and for bloom im using a 400w HPS. I was thinking of doing the outside with new plywood,drywall, and siding. Becuz i heard sheetrock promotes mold growth? And doing the insides with plywood,insulation,tyvek weatherproofing paper, and thin drywall cocking every crack so no moisture or anything gets in. First im probably going to clear the area and disinfect then start working on the outside, putting up plywood,drywall, and siding... Man the cop thing is kinda funny and scary at the sametime.

I live at Home Depot (I'm there alot). Around here they are very helpful. Looking at your pics a gotta ask. Is that moldy wood by that wired up window? I'm not crazy about partical board either especially with projects dealing with moisture it falls apart. They make a press board with big chunks of wood laminated together. That stuff is great with moisture because the glue they use is water proof. Ask the HD people about a vapor barrior on the external walls and how to help the walls to breath. This will help with the moisture. Also the floor studs should be pressure treated. A little $$ up front will save you big time down the road.

How is your project going?
You have an update?
I only have insulation on the garage walls.
I use fiberglass rolls that you can find at "Home depot".
The other two walls are actually a mix of different board types.
I recommend whatever is reasonably priced.
Got mine for free, can't complain.
The interior of my grow lab has been completely sealed off via White/Black plastic.
I left my wall interior open faced and used long strips of trim to nail gun the plastic up.
If you ventilate your hot air from your lights into the adjacent room it will act as a heater and should do well to regulate temperature all around.
I play darts and smoke in my garage. Since I exhausted into my garage I can do this at a comfortable 72degrees.
In the summer though it may be a little uncomfortable. Then I'll vent through the roof.
Hope that gives you some ideas.

get a pump sprayer and mix water and bleach, spray the walls, rafters, roof deck, and concrete floor. That's the first thing for any build out. If you need any outlets, do your electric ruff in before insulation of the walls. hang sheet rock on the ceiling. Mud the screw holes,tape the joints,keeping it smooth. plan your layout. cut your vent holes. cover the room,walls and ceiling with panda. Now your 1/4 done.

You can vent out the top of the room. You can insulate all the walls, insulation is cheap and fast. Oh , put sheet rock on the walls also, I left out the walls. Are you going soil or hydro? what is the size of the room? How many lights? You have water in the room? water in the room is nice.
