DIY Grow cabinet help

hey
i live in a country where marijuana is illegal, so i can't ship fem seeds nor a tent (draws so much attention), so i decided to build a stealthy cabinet and here's my planned grow op;

SETUP:
-i am planning on building a wooden cabinet, 150 cm width, 50 cm depth, 200cm height, split the room at 100cm width, resulting in one 100cm wide 50cm deep room, and one 50cm wide 50cm deep.
-get two QB96 Elite v2 for the 50cmx100cm room, and one qb132 for the 50cx50cm room.
-add ventilation and paint everyting white.

PLAN:
-since i cannot grow from fem seeds everytime, i plan on popping seeds in my 50cmx50cm room, select best females and use 1 or 2 as mothers and grow from clones.
-in the 50cmx100cm room i plan on growing 2 clones each cycle, veg for 2months with training and topping, then flower.
-so the big part of the room will be for an entire grow from veg to harvest and the smaller part will be for keeping mothers and clones (or maybe split in half height and veg two plants under CFL's if i can get my hands on a consistent supply of females seeds somehow).

QUESTION:
1- my plan is to harvest 500g each cycle (approx 4 months), considering everything (lights, environment, nutes, ph...) is in check, is a 50cm deep 100cm wide room able to produce 500 grams each cycle? or do i need to upsize the area?
2-i seek opinions from experiences growers, what do you think of my plan? is it the most efficient way to grow considering the limitations i face? or other grow styles (for example keep mother plants, take many clones, and then do a SOG 12/12 from seed in the other room) or (a perpetual grow where i put the 50cmx50cm room on veg and 50cmx100cm room on flower all the time, veg random bag seeds for a month then move them to the flower room, throw the males keep the females, veg some more in the veg room while the females are flowering.. and so on)

but the main question is; can a 50cmx100cm room hold 500g per harvest?
i live in lebanon so most probably ill be growing a lebanese strain, which is a productive strain.
i need to make the decision upfront since my financial ability is limited and there is no room for mistakes. i'll grow no matter what, and F*CK the government. peace

I'm new, but my research suggests you can expect 450g or so from a square meter of area.

...in perfectly optimum conditions, and depending on the strain. You should never "expect" anything when reading about yield.

True

I think you're going to find that too tight to hit 500.

so no way to achieve 500g every 4-5 months using 50cmx100cm?

Wait, no I take that back, you should be able to hit that with the right lights.

You can make your own feminized seeds with colloidal silver. I would use the smaller cabinet as a perpetual veg area constantly popping new seeds to feed the flower cabinet. You don't even need feminized seeds though, it's just more efficient than having to remove males during veg.

I would line the sides with aluminum foil and use good lights. 500 g is a lb. That is really pushing it to get that out of that space unless you are an experienced grower. There are several people on here that could do that hopefully they can mentor you. I'm not that good.

Its a big target to be hitting, I cant say its impossible because it isn't but its not common.
I can pull a pound from a 2x4 space. more on occasion but its work, if I scrog the best I have seen with a big yieder is 9.5oz in a 1.5x2ft screen, hit 18 in a 2x4 dry weight before, hoping to hit that again but what I currently have is not a high yielder so I will be happy with 14oz.

I would aim to increase your space slightly. Or go higher and split into two sections horizontally (check out @zypheruk 's threads)

Plenty of people cant pull 1lb out of 1mx1m

I don't really have much experience in SOG, though it yields well, 12/12 from seed may only net you 7-10 gram per plant.

I cant split the room horizontally since ill be using quantum boards that should he at least 30cm away from the plant.

The biggest issue with a 1m deep room is stealth, it will draw unwanted attention.

So a 50cmx100cm room is physically unable to hold 500g?

The Stealth/Micro Cab Section here at RIU might be a good place to find some answers. It's not as active as it used to be but there's plenty of examples of what others have done with limited space/resources.

I used to get 400g out of an Ikea closet using 400hps so I don't think you'd be that far off with quantum boards and the right strain with the right plant numbers.

Do you live on your own? If I were you I would kit out a walk-in closet rather than building a cabinet. When I first started I was trying to veg and flower in my closet, which meant vegging in a little cabinet that I built. That cabinet is now storage, and I veg in a tent outside of the closet. The closet is now just for flowering. If my math is right, one foot is approximately 30cm, so your dimensions seem pretty small.

Do you live in a dictatorship where internet traffic is censored and monitored? If you do you’re already screwed for posting here about it and ordering a grow tent won’t change anything. Unless you live in someplace with really crazy laws like the Philippines I wouldn’t worry about ordering seeds or a grow tent.

I also want to strongly recommend Atreum’s boards over HLG’s. They use the same lm310b chips but the finish is a little nicer and they include a very nice machined aluminum heatsink with the board at no extra cost. They’re also less expensive than HLG boards. I’ve used them exclusively with my light builds and I’m very satisfied with them. They’re nice people and I chat with them on insta quite a bit.

Not unable, just not common, would depend on the strain and canopy management. Limiting the space limits the potential yield regardless of how nice your lights are.

Since your building a cupboard I would go floor to ceiling, allow two flower chambers and a veg if you can, get as much space as you can without been obvious.

If your using quantum boards in the minimal sense , two boards powered fairly hard, you want 18" between tops and light. If you run more boards ran a bit softer you can get them closer but obviously it costs more. Though if you run enough of them you can do it without heatsinks so can save some $ there.

All I can say is in the space you have qb's are not the way to go, strips give better spread, can be run really close to the canopy, and less concentrated heat because there is more airflow around the strips. Scrog your plants properly and your yield will give you a little shock. I personally wont be getting into the debate past this as I have a lot of work to do in my cab before I can get flowering again. If you need any ideas just take a look in my diaries at what can be done in low height and narrow spaces.

I agree completely and would have suggested this if it had occurred to me. Strips are a lot better for what the OP wants to do. A 120 watt QB still puts off a fair amount of heat. Once you get your lighting figured out you’ll want to figure out how to ventilate it for optimal conditions. Refer to the vapor pressure deficit chart for this, because it will have a lot to do with the ambient temps where you’re growing. I run a single 120 watt board at full blast for vegging in my tent. Without an exhaust fan it would get toasty in there and the driver isn’t even in the tent. The driver never gets very hot though.

in the middle of this atm.

II decided to get a 60cm deep 180cm wide and 200cm high cabinet. Its over my budget but this is the perfect size for stealth and limitations in my apartment. That way ill have a 2x4 room powered by a 250w quantum board for flowering 2 plants , and a 2x2 room split at 50cm height to make some room for clones and/or moms, powered by 125w quantum board for vegging 2 plants, and some t5 strips for the clones and mothers. Sounds good? ?

And no i dont live in a dictatorship i live in lebanon but i prefer to take extreme precautions and stay safe. I am sure fem seeds wont make it through the customs, and the tent draws attention in my place not when ordering, thats my concern.
And btw im posting from a secured network so no one can really know my real location

This looks badass. Kinda hard to visualize for me since I’m used to looking at construction blueprints which always have more context, but I see where you’re going with it. I’ll have to check out those Samsung influx strips. I love my Samsung chips.
