New setup. Unsure about circulation.

Hi. I have concrete room with no windows (only door) with a fish pond next to it. I have 2 fans. a 8 inch extractor fan attached to a scrubber that would exhaust the air into the pond (in the water itself) and then a 6 inch fan as intake. However that intake lies 4 inches just above the pond underneath a flower box. What am thinking is may be the air am exhausting will just be sucked up again by the intake fan. Am I correct?

I was thinking may be the fish in the ponds would produce some co2 that could actually be sucked up..not sure of that though..

Also I cannot run an AC since my dad will notice the compressor outside. So it is out of question to use an AC. Hence am trying to promote continuous air circulation. The room is 11 feet by 11 feet. I am planning to get 14 red dwarfs and 1 big bud in it. I dont have any co2 enrichment (does any1 know if fog machines produce co2? coz i can get my hands over one). I use salt to remove humidity and I have a 600 w HPS and a 250W HPS


Any suggestion as to how am going to hook up the whole setup? I mean how to adjust the timers of the fan combo and the lights. I plan to switch off light for 6 hours during the day when temp is hottest. Also how about the air circulation? what would be best? do i leave it as it is or I drill another hole in the walls on the other side?

You have a good start here. As far as AC goes, if you don't have any, you will need cool tubes. youy can't have the intake next to the exhaust. Whatever you do, make sure your fan is sucking the air through, not blowing it around. You will need an oscillating fan for circulation. High humidity will make a scrubber fail, you'll smell it. Better put it somewhere away from water.

Seems like you might have some dampnes issues there, but the size of the room is going to make it so much easier for you than a closet.

One trick I learned, was simply to leave all the lights on all the time. When you flower, just move plants out of the light into a dark room (with air circulation) every 12 hours. You will double the number of flowers this way. The drawback, is you have to be there to swap the plants out twice a day.

Don't even think about CO2 until you have a couple grows completed in any given area. You'll need the experience.

You have the potential to make a full out grow area that can provide you with a couple zips a month if done right. Problem is, your dad is going to notice. It will make noise, there will be traffic, messes, stuff thrown in the trash, electric bills will rise noticeably, etc... You have the makings of a nice room, it's just going to be hard to hide.

Whats your outdoor amb temp? Do you have the exhaust pipe under the water?? This sounds interesting! As Prodigal says one step at a time lol. If using CO2 you will have to stop all ventilation while using if you want it to actually be effective. And I assume Prodigal meant move plants from light to dark and other plants from dark to light?? how far are the intake and exhaust apart, 3 feet is lots BTW and could get away with less if terminated properly.

See the product in my Sig for C02. So, your dad does not know you are going to grow in his house? If that is the case you are going to catch hell here by most members...

Are you living in this room as well?

thanks for your advice mate. Am not sure what you mean by sucking the air through and not blowing around.. I am going to buy a bladeless oscillating fan today.I think it makes less noise. I presume if I cannot control humidity the scrubber will fail. Does that mean i need to buy a dehumidifier? BecausE i dont have any equipment to measure humidity. I thought of using salt just to save on cost of dehumidifier and also less heat in the room.

Not sure what to do now though.

Well in summer like now is between 24 - 30 degrees C and winter drops to 20 degrees. Yes the exhaust pipe is under water. The pond i build is about 1.5 feet in depth and the exhaust goes into the water itself making bubbles to hide the noise from inside the room. Imagine a wall with 2 90 degrees 8" PVC bends coming out from it. Each of them 3 feet apart. As both of them leave the room they go through a flower box. so the soil in the flower box hides the bends. Now i use one of these bends to exhaust the air. So the one exhausting is conected to a pipe that goes into the water whereas the other is is not connected to anything. you cant see anything. You will have to go in the pond, bend in the water to see under the flower box to see that it has an 8" hole :) but now i presume i wont be able to use it. right? What u meant by terminated properly?

Well am not really growing in his house. He lives ground floor and I live 1st floor. But he has access to everywhere. I build the room and pond on the unused ceiling floor of our garage. i told him am just building a porche :) The grow room is outside the living area but when i say outside its still in the same compound. It difficult to explain.

I think if I manage to create a negative air pressure in the room the smell cannot go out ( this is used in hospitals) and i think thats easily achievable. The concerns now are only for sound. Here i got the pond. And I am hoping that the sound o bubbles through water will mask all other sound. As for electricity..well you know...i think you guessed it already :) And i did ll that by myself...no1 knows about it

I was talking about your evacuation fans, the ones used with the carbon filter. The fans are more efficient when you set it up to suck through, and instead of blowing through.

Yes, negative air pressure is what you want. If you go with CO2, it won't work. As soon as you get enough airflow to create a negative pressure, you will suck all the CO2 back out of the room.

So, you don't think your dad is going to check that room out for 3 months at a time? Do you have any clue how much weed smells when you harvest it?

well when i harvest am going to chop everything at once and use the same room to dry up. I know that some might not be ready yet but this is how am going to do it: chop everything and then new set of crops. Fan with scrubber will still be on, Lights switched off. And yes I know how much it smells :)
