Ventilation

So... I don't have ventilation per say and I am wondering how much this will affect my flowering period. People with experience with and without chime in. I do keep the door open for awhile but this is the last part of my setup I have not done.

extremely important, circulate air for now at least.....put a fan in blowing on the plant till u get your intake and outake vents and fans set up.

only exhaust is necessary. passive intake will be fine. get it set up asap.

I have fans and ac for the summer installed and it is getting cold so I have a shop/room heater for the winter. I just seemed to fix everything except the intake and filter. I also wondering because for a test I kept a tomatoe plant and jalepeno in my area and they didn't flower and bloom. My white skunk is taking its sweet ass time also but I had a pretty good light leak I overlooked. I try to keep the door open at least when it was warmer for a couple of hours.

put up a pic and its easier to answer.

the picture of my setup is older and is now more complete. I put the light above the table which is unscrewed and movable to size when they start grwing close to the light. It is in a attached shed wich is sheetrocked and has electrical.

Ventilation is the second most important thing in an indoor grow. Keeping your room well ventilated reduces humidity levels and removes excess heat. Your plants need Co2 and unless you exchange the air frequently your plants will use up the Co2 in the room quickly. This can be mitigated by supplementing Co2 with a bottle. I wouldn't even think about running a LPG Co2 generator in a sealed room. Even if you do use Co2 you really need to keep your humidity levels down. If the humidity gets to high the stoma's on the bottom of your leaves will close reducing the amount of nutrients the plant can trans relocate. No nutes, no carbon, no grow. It's that simple. Also humidity levels have a lot to do with pest. Most pest like higher humidity. Spider mites in particular love the higher humidity levels. It actually affects their breeding cycle. When humidity levels are above 60 % in warm temps they can reproduce every three days making it next to imposable to get on top of an infestation. Long story short; you really need to vent your room.

im also looking into ventalation so far i have fond this:

http://www.icmag.com/ic/showthread.php?t=29341 - stanley blower , moves about 256 cfm and for 45$ thats not bad
https://www.rollitup.org/do-yourself/234834-diy-icebox.html - then i plan on making an icebox
http://www.icmag.com/ic/showthread.php?t=33123 - and then make a chiller to keep it in a cycle as to not waste water.

also with this method you can have a closed room so you can put your c02 in without wasting it and recycling the air.

total estimated cost to make this unit:
50$ for radiator
10$ for mounts
45$ for stanley
10$ for ducting
30$ for used craigslist water cooler
10$ for a used icechest
total: 155$

not bad considering thats the price of "the ice box" alone. also you could use a used radiator from a junk yard or something i just would rather spend the extra 20 bucks to get a new one and not have to really scrub a used one down.

thanks guys I will get this part of the room done asap and see if it fixes my issues.

I have a 30 dollar 6" fan. It doesnt seal when it stops. it looks like a big industrial fan in a 50's warehouse.

I am running at aroung 70% humidity at the moment and was going to buy an aircon. however, would it be better for the carbon filter potential and humidity reduction if i just invest in a good 'cone' shaped, sealing fan that pretty much the entire world uses? I have been fine with this exact enclosure for years ( i run stupidly high co2 to kill bugs )

It will be louder but will need to run less time. Would a good exhaust fan be able to reduce the humidity in an enclosure, significantly? (my current fan removes smell, but doesnt seem to affect the heat or humidity at all. also doesnt block co2 escaping.)

thanks for any wisdom.



thanks for any advice.
