First time indoor basement grow

Hey farmers just was given the opportunity to start this basement project i have limited experience growing last year outdoors with success but understand indoor can be significantly more difficult.
Right now the basement at 7ft ceilings not surr if that's tall enough it has dirt floors i have dug about a foot already to get it to 7ft but can dig if needed.
After ceiling height is correct i plan to use 6 mil plastic on the floor to create a vapor barrior and a thick durable tarp on top to help keep the barrier intact maybe thinking plywood floor on you the tarp but not positive yet
I plan to insulated the ceiling and again use 6 mil plastic ceiling
As for walls i plan to run 2x2 to outline on ceiling of the room and stakes for the bottom. Id screw plywood to 2x2 at top and stakes at bottom and seal with foam
Not sure the stakes are the best idea but it would create a solid wall im thinking
venting straight from outside and exhaust straight into the rest of basement using charcol filter
the room would be about 10×10 after built would be lined with white plastic
I have 20 led lights i plan on using for grow i don't have all he specifs on them yet but they are quality lights thats have grown good flower full spectrum will post soon
Any ideas or tips any one can give is appreciated any idea of possible yeild out of a 10x10 basement does hold moisture which is why I'm using vapor barrier and my air for the room is vented from outside

I wouldn't dig out more as that has the potential of making the foundation footings less stable.

If there is a humidity problem a dehumidifier will be in order.

As to attaching walls to the floor, using wood, especially non pressure treated lumber will be subject to rot if the soil is moist. A concrete footer would be the best way to go but I know that is more work.

don't mind concrete just wondering how thick would it need to be can a 2 inch floor work

What if you just filled that hole with dirt and plants? kind of like an indoor raised bed, but lowered lol

Depends on the stability of whats under the concrete. Probably smart to put some steel rebar or at least some welded wire fence like this

One concern there would be drainage.

Would be cool though to dig holes for buckets and plumbing to connect them all together for a RDWC thats mostly below ground. That would probably help keep the nutrients cool. A shop vac could be used to empty the system.

Yeah maybe a good layer of stone at the bottom. I don't know just an idea I had when I saw the hole in the floor .

I dug it out to create more vertical grow space im at 7ft right now im thinking that should allow good yields

I plan on using smart pots and soil

I’d put some rigid foam board on the floor and plants on top of that to help keep root zone warm. Check soil temps to see if they are warm enough for direct plantings for that is what wou want to do.

Didn't think of foam board but sounds like it would definetly help thanks

if your uninterested in pouring concrete for a slab, you could use preserved wood. could put crushed stone down and compact it. put a layer of poly ontop of the stone once compacted and level. then frame a floor system using preserved wood. would easily be half the price of concrete.

Thanks

I think a pond liner for floor prob be tougher than poly. Instead of plywood or in addition to plywood you can use those big 4x8 foam insulation pieces that are silver on one side they work great for reflecting the light.

I agree with the pond liner. 45 mil and it's tough too. Not cheap tho.

This correct pond liner

Yep, thats the stuff.

It is high look like 200 for a advert the size i need im now not positive bout the stakes at the bottom 200 i don't want anything puncturing it
