ventaliton & smell?

ok so i have a 1.5 m by 1.5 m by 1.5 m depth (m for meters ) in the middle of my room in the garage with carpet ova the trap doors,
im planing on growing 5 plants with a 400w hps lamp.
will ppl be able 2 smell the plants when they get 2 flowering stage?
im planing on opening my trap door for an hour each day..will the smell ingolf the room for more then an hour..(my room is 3 by 3 meters)
is that enough to let out old air and bring in new?
plus i have a fan 2 serculate the air in the hole

i herd about theses glad plug ins..the kill odour..does anyone know where i could get them or have u even herd of them?!
anyhelp wil help

ok...now we're getting somewhere.....your space is good enough....for 5 plants that is....the air will be renwed every time that you open that door....you don't have to keep it open for one hour.....you see, every time you open the door a small stream is created that exchanges the old air with new....in the meantime any odours will escape to the outside....the plants start smell from week 3 or so during vegetation, only the smell gets stronger as the plants get bigger....now i am in week 2 of flowering and i can manage to handle the smell by burning a candle right outside my growroom....propably i will have to burn more candles as the time goes by and my ladies produce their flowers...burning candles is really helpful because as they burn, they kill odours and produce CO2 by consuming the O2 that is in the air.....maybe you can handle the problem better by using an ioniser which produces negative ions that clean the air...i replied to another question you posted to this forum already.....your space of 1,5x1,5 meters is ok for your 400 hps and can accomodate maybe another 3 plants....keep it at 5 though as when they grow to 3ft/1meter you will be able to move around them....i grow 8 plants into a space of 1,5x0,8 and i am simply not able to handle them without changing their positions every time i want to tie them down or do something with them.....if you have any questions , simply ask....there are many people over here that will gladly answer them!

exactly, i could not have said it better.

thanks bigtime man..that helped alot
i was thining of making my own ozone generater
looks pretty simple.
but do u burn your candles 24/7 ? or just when the smell gets bad?

i use the candles outside the room so as the escaping odors will not be detected from someone that happens to be around there (not that there are people there, just in case)....this candle i use in 24/7 basis (of course i keep changing it when it burns out)......today i started burning a candle inside the growroom so as to consume the oxygen produced by the plants and in exchange release CO2 that in return will be used by the plants for their metabolic activities (photosynthesis) and thus grow bigger faster.....however it is not wise to burn the candle when lights are out because in that time the plants a)need oxygen and b)this would interrupt the dark cycle and propably as a result they would turn hermies :)
