Hey every one i have recently moved to the country and after much debate with my friends,
I have decided to make a "hidden" room underground somewhere on my property (over 400 acres)
since i really don't want to try to grow out side ( i see deer all over the place).
I cannot grow in the house since my significant other does not like it :wall: .
But I have always wanted to do it I have searched the forum all over and have not found
any threads on digging and making an underground grow opp.



So I have 3 Questions I have searched for on the forum but I cannot find any Topics on it

I have made a basement before so this will not be a problem but I am worried about the roof
any suggestions to make a roof I can cover with dirt and it will not rot?

I have no electrical experience how will I grab a full power line from one of my buildings and
get it to my “hole” (I don’t want an electrician to do it)

And lastly

How deep should the roof be underground so there is little or no heat signature from the ground?


So I have
- Tractor with a back hoe
- 1000 LB Cement mixer
- Lots of cement
- Rebar
-
Any help would be awesome

Thanks
Sean

i have seen 1 underground operation before........my friends dad.........it was under the shed...well small garage but yea a shed. the floor had a trap door under a tool box that sat in the shed on top of carpet........i partyed in there all the time and never suspected anything until she told me and showed me.


the walls were angled in dont know why but they were. and the ventilation system went out orf the roof of the garage shed type thing.....it had a garage door but never parked a car in there just lawn mowers and stuff......

as far as the electric......it is not hard to hook up just run it and tap into a panel somewhere...very easy i am sure you can get someone on ehere to help you with that part

ok that’s a good idea if i make a new shed or something it would not look sketchy if its warm eh? But i want it totally underground and non-discoverable though…

The place i have chosen is really bushy area on my farm so i was going to just put a trapdoor hidden somewhere. i have a friend good with pneumatic actuators and he is going to make a large trapdoor with 2 powerful pneumatic actuators tied to a remote so all i do is go there press the button on my key chain and presto the door will lift vertically so i can pile like dirt and brush so it will be very discrete. i know i am going over board but i want a flawless grow room

I have seen underground grows on the internet. One had semi trailers buried that were connected together to form different rooms. Another option would be a conex container. The containers you see on construction sites or at receiving ports. These containers sre designed to stack on top of each other so 4-5 ft of earth won't collapse them. You could paint the outside with a rust inhibitor.

You will probably want to bulid a small building or shed to conceal the entrance. A little dilapidated out building in a random place on a farm is pretty common so I'm sure no one would suspect anything.

Running electrical to your site should be run underground in grey electrical PVC conduit at least 1' deep. So you will probably want to be somewhat close to your power source. Then you need to consider whether or not you have enough power coming to your existing electrical system to adequately provide juice to your grow op. If not then you will have to get an electrician to help you. Just tell him the lil outbuilding is going to be a workshop and you need power run to it to run tools and what not. When he asks "why isn't it a lil closer to your house?" tell him that your wife wanted to move out to the country for some peace and quiet and she'll be deamned if she is going to listen to you bang and tinker out in the shed all day. A generator would also work well.

You are also going to need water at your site as well. I would suggest a well. Tell the well guy the same excuse you will tell the electrician. Good luck with your endeavor.:bigjoint:

You say you have a shit load of concrete and rebar. You could just construct a basement under your building.

alright, building an underground grow room is a lot of hard work if you're going to do it yourself. do you have access to a digger?? how big do you want this to be??

and don't be ashamed of asking an electrician for help. they don't care what you are up to, as long as they're getting paid.

don't construct a basement under you're house. you risk damaging the foundation, and that will end up costing a lot LOT more than you ever EVER EVER wanted.

he never said it was going to be under his house.

Anyway, for safety sake get an electrician involved. You could say your building a storm/bomb shelter. Only problem with that is that he will likely have to pull permits to pull power from your main breaker panel. Remember that this is still going to be tied into your house electric so you want it done right. You should be able to find an electrician that would do the work without permits but he wont put his name on it.

As far as size goes, that depends on you and how much you are wanting to grow.

i think you would be a lot better just building an above ground structure preferably near your house. just have an electrician hook it up with enough power, and water can be hooked up using hoses, that shouldn't be you're biggest concern. what you should be worried about is the cost.

a secluded, underground grow op, with pneumatic whatever can run you about 60 grand plus, and that's without any grow equipment, that's just digging the hole, and building the damn thing, running the electricity....then you have to worry about water seeping in, mold and a whole host of problems underground structures face.... fuck that.... underground grows are notorious for attracting LEO because they grab headlines anyways....

a above the ground grow room, even made out of concrete will run you about half of that, without many of the structural problems.

i'd just build a concrete structure, doesn't have to be big. 10' x 10 ' inside will allow you to get 2 4.25 ft x 6.5 ft rooms, plus a little foyer/storage area it's plenty of room.

i attached a pic of what I would do, imagine the walls are 6" thick, for illustrative purposes... i know 6 inch walls are probably not going to be used, specially if you use board or wood to make the interior, but it's just for an example!

i would also recommend looking up ways to disguise the exhaust, which actually shouldn't be a problem, cuz that house can be a utilities housing unit, giving off exhaust is just part of making you're house livable. especially if it's out in the middle of nowhere.

here's what you could do, it's crappy, done in paint, but yeah, i'm too lazy to fire up the autocad right now...

he doesn't have to explain shit to the electrician. he could say it's his personal man-cave. he needs all the power because of the entertainment system, kitchen, etc.

You'd have some pretty serious pressures underground, Surely you arent thinking about making it all from concrete though?? (of course it'll depends on how deep you go. Just get insulation in there to disguise the heat signature. The chimney would be a dead giveaway though!! LMFAO

Here is an excellent suggestion from a dude @Grasscity

Well if I had a hidden basement with marijuana I would install a extra telephone line.
To the telephone line I would install a electronic relay machine that responds to codes. So when you call to that line, you would be asked to enter a six digit code.
After entering the code the electric relay would activate a fire that would burn everything in the room and then activate a water line that would put the fire out.
When you get arrested you have the rights to one telephone call. And with a massive armored door it would take the DEA atleast 24 hours or more to get through the door.
Insane I know, but hey that's just me
