my situation, need advice.

I got a blackstar 180 flower and the 3 fans on it are loud to endure or to stealth it.

i got a built in storage shed in my house, it is only partially heated and too cold to grow, but with the led in a small 1'x2'x4' box with small drilled holes for a passive intake/out , the temps are good. the led fans makes the air flow. the led needs to stay on 24/7 to keep temps up, will passive intake/outake outside colder air be enought to not stress the plants. and i only got a few lowryder #2 seed.. can it do a seed run on 24 hour light, how does a 24hour compare to a 16/8 with lowryders in terms of days/potency/seeds/yield.

even autoflowering strains require a dark period to recover and produce more flowers. I would say 16/8 is good. 18/6 works too, and I've even had success with 14/10.

Try it out and see what works. As for your air flow, have you tried kaulking the holes or even using duct tape?

? do you like with your parents or why is the noise an issue. I mean if you have a shed you should have more locations to place, my personal favorite is the basement or attic
