Need help with stealth microgrow

Grown once before and failed - outdoors plants were practically growing in mud and got found!
yielded an amazing 0 pounds, 0 ounce, 0 grams.
given the seeds for free so no loss, just experience gained right?

I wanna grow indoor this time in a little space i got where no1 will know I just need help fine tuning/ completely dismissing my plans

first off Im gunna fork out and buy Lowryder #1 seeds (small, low odour, autoflower)

gunna grow in a white sprayed plastic container about 12" x 6" x 6"

Using a rectangular plastic plant pot container with miracle grow soil for grow medium

Got a 100W equivalent (20W actual) CFL thatproduces 1160 lumen (can easily part with, didnt cost)

I'm tempted to skimp out on ventilation, as i've hear with grows so small just opening once or twice a day is plenty ventilation. That and it also means smells easier to control.

Will use a Thermostat or whatever to measure temperature

Will water 2 times a week, only introducing nutes if it looks like i need to

Might use LST with gro


If people do agree with my setup i'll give it a test run first to check temp humidity and other stuff

Feedback please? Will give rep for first helpful reply

12" doesn't leave much room...Have you considered doing a stealth PC Grow box? You can grow a lowryder to full maturity in one and still remain super stealthy. I actually have one on the way and plan to grow a similar dwarf strain. Also you can do soil or hydro and there are plenty of journals to follow outlining all the do's and don'ts. Check out crazytrains posts. You can build your own or get one one online. That way you can basically learn all aspects of the grow using the same techniques just in a smaller environ.

my grow box is practically the same size as yours, im using 2 23 watt cfls. you definitely need ventilation sorry but its a must, i grew in a 12*6*7 without ventilation with 2 23 watt cfls and i left for a day, came back and my plants died of heat stress. ventilation is a must. its super easy, just take out a fan out of anything that runs like an old ps2 or an xbox, just connect that to an old power charger and hook it up to your box so it sucks the air out of the box, then poke some holes in it for intake. super supe easy, and also your prolly guna need to water more in such a small box especially without ventilation. their guna dry up fast.

you need more light more space more ventiliation i got a small cabnet grow with 4 cfls and need to open alot to not let it get hot since i dont got fan yet
