i think u would have to make it out of brick/concrete. what happens when u get a hard rain and that wood is the only thing holding that wet dirt back? not good....
but i do think its a good idea, if done right. the plant material above(grass?) would block out the UV rays, so a cop chopper with a UV camera cant see it. maybe not all, but some im sure. also it would have to be a pretty big hole for it to be worth it. i once thought of burying one of those 50ft cargo containers under my yard =P that would be such a sick growroom
that would be awesome
, sick grow room. and dont worry about the walls caving in, i dug a 6 foot deep hole in my yard and not a drop of water anywhere near, and the walls didnt fall in or anything, just depends ont he soil....
im pretty sure some wood with some waterproof plastic on the outside will do for the walls and floor..
just have a large sheet and then fix beams accros lengthways, insulate and add more wooden sheets.
the roof would have to be waterproofed aswell.. if it was outdoors then it would be difficult to make it look natural afterwards.. but under a shed or porch would be fine i think...
it is feasible to place a grow box underground but i don't think it's a safer idea, police don't just kick your door and find your growroom by accident, and if they already know that you grow, then they will find it. they only have to watch the garden to see and take pics of you opening the growbox lol. i'd find an indoor private spot to grow in and keep my mouth shut about it, maybe smoke less, and take long breaks between grows like i do. this way you will be much less paranoid. seriously, if you dig a hole for real to hide your grow, you gota hit the clinic lmao
the cops bust grow houses all the time with crap evidence, a bit of heat from an upstairs bedroom and some shit intel and they will raid you... you see it all the time, they raid a house and fine fuck all... it would sure give me some peace of mind..
not long ago i decided to think of a more secret grow room ... i was up strairs and my friend dropped a mirror and if fell down the stairs and smashed at the bottom.. i was in bed at the time...
Can you imagen how fucked up and parranoid i was running to the grow room ready to eat all my clones tripping up as i try to put underwear on so im not busted in the nude.
what would you think if your woken up to ... BANG BANG BANG BANG BANG SMASH!!!!! i would have felt a lot better about the grow being burried lol.
It dosnt matter if its solid dirt, ground water will seep in if its more than a couple feet down
To make it worth while, the hole in the ground would need to be big enough that you could walk into it, so your not just taking the lid off a hole in the ground and trying to reach down 4 feet to tend to the plants. I would lay the base slab first, then lay concrete walls in.
But concrete is porus and water will leech in thru it, so you would have to water seal the concrete floor and walls.
Then for the roof, lay some heavy corugated iron sheeting over it, then lay a slab on that with reo mesh in it.
Im not sure you would need a sump pump or not, if you could water proof the concrete...
You would need a power feed from your house on a circuit that could handle all your lights and fans ect, and a water feed, and a water drain which would be hard since you cant use gravity to carry the water away back up, another pump needed for waste water
you know people make these underground grow rooms all the time, and the cops still find them, they just use a dog to sniff it out
you can prevent this to some extent by rubbing a bag of weed all over your house and garage and everywhere, the k9 will be alerted to all areas and no specific area will be pointed out as suspect... you have to re-rub every now and then to freshen up the decoys
just some thoughts...
Thats a good idea too... I used to carefully pull back my grass in the yard, dig a hole and burry my weed in a box.. then put the grass backand let it grow over the box.. if i needed it i could still get to it without killing the grass. if you have a dog make sure you bury it under a pile of dog shit... then it wont look so bad when the dog sniffs it, pretty sure they wont dig it up.
