is it ok to grow in a open room as long as in dark time it has no light ?

i will be growing in my basement. about the same size as my living room.
in its dark time ( at night time ) its near enough pitch black.
and i will be using a fan for circulation
but i have no exhaust thing set up but there are like 15 small holes in the wall leading to the outside below my front door. ( its a flood gap )

will this be ok or do i need a proper exhaust.

Darkness at night, and good air flow are both pretty important.
Sounds like a damp space to me, so I'd sterilize it pretty fiercely...
Plus, is it cold where you live? If it's freezing outside, it's going to be
pretty chilly on the other side of that wall.

Good luck though! Sounds like you can fit lots of ladies in there.

P.S - If you're worried about effecting your plant's night time cycle, you
should most likely be more worried about light leaking out in the day.
You can still see grow lights inside a room, from outside, during the daytime.

to be quite honest, its not a flood gap at all. i think its just house ventalation haha
but to be honest it is kind of damp down there.
theres no chance i can do this any other place though.

i guess damp means bad then..
and yes your right i could fit many many ladie in my basement.
although its my first grow so only one lucky lady this time round.

If it's your only spot to grow, then just adapt it to suit your needs.
A long time ago I did a few rounds of 100 plants in a basement in Whistler.
This place was probably the worst spot to grow imaginable. Dirt floor, actual water
seepage, ridiculously low temps at night, and there was mold down there to start.

But... with some prep it worked out great. Wasn't easy, but doable.

First of all, i would seriously recommend making yourself a grow space out of black/white
plastic. You really want a contained space. I started with a small tent like structure framed
out of 2x4s and added 10x10 room a few weeks later, leaving the smaller room for veg/cloning.

Framing lumber (spf) is nice and cheap, and plenty of hardware stores sell Black/white poly by the
linear foot. So you can just figure out what you need for your space.
Home Depot also sells zippers w/ taped edges, used for site protection. Just peel off the backing
on the tape, stick it on your poly wall, make a quick cut with a razor blade, and you have yourself
a fancy zipper door into your grow space. They cost about $10, but are just so snazzy and easy to
install.

I also started with one plant, but vegged it up a bit and cloned it into oblivion. It set me back some time,
but I was a lot better off harvesting 20 plants and waiting the extra time. Those 20 I cloned far less aggressively,
and more than doubled my harvest for the next cycle.

Good luck sir, will check back to see your progress.
Just joined this site myself, will post you some pics of my old basement when i find them.

you might want to think about getting a dehumidifier that might help a little and a heater if its to cold besides that clean up and give it a shot good luck

If your on a low budget then yea you will need to do alot of prep work like try said i would also say making a grow space inside of that room like a tent or box white or reflective if you can that could help with unwanted surrounding and maybe temp

Go right ahead and see what happens, no reason not to. Good luck.

By the way I'm sure I can find 20 reasons not to but that's not the point, you go with what you got, so get at it and quit talking and start growing. If you have issues come back and we will help you.

i guess he took that literally wood lol

nothing inherently wrong with what you propose. The plants won't be offended by the room they have. Really you are just left with the things every grower has to deal with, heat, venting, light, etc. Having exhaust is important, but if your area is large enough and you have good air movement within, won't be necessary. Only way to tell for sure is get lights going, and find out temps. could go either way, but the proper way to do it would be some sort of venting regardless of heat (oxy/co2 replacement is often overlooked, but can be of paramount importance). If that fits your budget/situation, then by all means do it, if not, see if it's a necessity with a day or two of dry runs and look at temps.
