people have told me to keep it on bc potential of mold issues and that there is no benefit except saving electricity but the risk of mold is not worth it. You told me not to but for me to know if your answer is legit i asked you to explain why to turn them off.

i need more help here guys im still confused on what is best! thanks! +rep

well your not really helping me here so either explain why not to exhaust during the night or move on to another thread. not exhausting i feel like will lead to mold problems potentially since plants transpire at night. If they do not use co2 why is exhausting a problem? whats the benefit to...

its giving off co2, your talking about co2 here im assuming

so leaving co2 in the tent at night would not be ideal when i can exhaust it into the main room and into the other tent that is in an opposite cycle therefore needing and taking in co2...

that will lead to mold i would think if air isnt moving through there... are you sure plants use co2 at night?i know they give it off at night and absorb it during the day...

? why not just leave the fans on.

im not going to vent one tent to another, im going to exhaust into the same room and draw air from the same room. the tents are in the room so while one tent is 'on' taking in co2 the other tent is 'off' putting off co2.

that chicks got a dick

so would the co2 be a benefit to do the room like this?

maybe i should be asking....has anyone tried transplanting mid flower and had BAD results?

what is the risk here?

? i cant transplant yet, the pots i am using are doing their job of air pruning the roots and wont be ready for transplant anytime soon and i need to put them in flower or they will be too big....all i am asking is if it's ok to transplant during flower? i understand its recommended not too, but...

is it ok to transplant during flowering? i am using rootmaker pots and i need to put my babies in flower but they are not ready to transplant just yet....maybe in a month. if i put them into flower now and see that they need a transplant mid-flower is this ok? will it stress them too much and...

So these are some new fixtures that my company makes for growers all over the world mostly commercial and not just cannabis, we dont stock inventory and are gearing up to offer our product on the retail end through third parties...i am not going to spam if you want more info such as name or...

i have a room that is 11x10x12...in it i am putting two tents, 5x5...each tent exhausts into the room and pulls air from the same room...question is can i seal the room with the scenario below....thanks ahead of time! since plants produce co2 at night, oxygen during the day my thought is if i...

the video was great, no such thing as too much air circulation if there is no co2 involved since normal fresh has very low ppm.... next grow i will do co2, thanks to all!

very nice i understand it a little better, thanks. but in a sealed room are plants themselves providing enough oxygen/fresh air? and do you need to use CO2 in a sealed environment? with me having a tent inside a room i can see myself putting a AC unit inside of the room and my tent will stay...

look in my signature for the diy your light...this will be fine, it is all cfl but this light and reflector kicks ass. i grew 2 good size bushes with decent yields, hps would of been better but this shit works....use 2700k bulbs for flowering tho, maybe leave in 2 6500 bulbs... both 2700k and...

i still dont understand how you can grow without bringing in fresh air, if you keep using the same air over and over how does that work? why do people advise to circulate fresh air as much as possible? thanks to all helping here +rep on the way
