placing a big order for new grow room PLEASE HELP

i have made a couple of threads and havent really found what i want. Tomorrow i am ordering 2 1000 watt hps air coolable lights that will go over 20 plants in an 11x11 foot room with 7 foot ceilings. I have a seperate bedroom for my veg that will have 2 400 watt MH. the main ? i have is i will be exhausting through a carbon filter then through the lights then out of the room. What size carbon filter and inline fan do i need for the exhaust. And also what size inline fan will i need for my intake. I also need to no what size fan for my veg room it is 7x7 with 7 foot ceilings. I will be growing in soil in 7 gallon buckets.
Thanks for all help.

Light cooling should be a seperate circuit from ventilation systems. The intake for the lights should be outside the grow and the exhaust should also exit the grow so that the air never mixes.

Its math here this will answer your question https://www.rollitup.org/grow-room-design-setup/126799-ventilation.html

I was wondering if you guys could take a look at my order and tell me if i am missing anything before i order and if it is the right stuff i need. Here is a little info on my room.
I will have a bud room that is 12x6 running two 1000 watt hps aircoolable lights with 20 plants under them. The veg room will be 10x7 with two 400 watt mh lights in it, also with 20 plants. the set up is in two seperate bedrooms. Is this Carbon filter gonna be big enough for 20 plants? any input would be great. Hopefully ordering tomorrow.


Wow, thats a lot of information. Carbon filters are not sized by the number of plants, there are sized by the cubic feet of air they move. What you want to be ale to do with the carbon filter/ exhaust system is replace the stale air in the grow area with 'fresh air' every three to five minutes, do the math. Understand that the listed cfm is with no flow restrictions, no bend, no twists.
I am not real sure what you are trying to accomplish here. 12x6 room 2-1000watt lights, ok. What system, medium etc are you planning that you would only have 20 plants? What is the height of the room? You will need, this is not an option, to air cool the lights. Period. Let me explain, it saves you money in the long run, and lots of grief. Without it you will fight to maintain all of the other things in the room. I just installed a 1000watt light, air cooling dropped the temperature in the room 2 degrees. That 1000watt light replaced 2-4'-8 bulb t-5's. Its over (2) 3'by3' flood tables, at one plant per sqft, a standard for most soil grow, that would be 18 plants? Why are you planning on only 20? The light covers these two tables.
If you are only going to feed 20 plants into a 12'x6' room you will not need (2) 400watt lights. The plants will be smaller and can be covered with just one. With the information you have given, I would suggest dropping one of the 400's and getting the cooltubes, more information about the type of grow may help us give better advice. VV

Soo.... what makes you think putting all of the information in one thread is a bad idea.
You haven't gotten what you want because you are setting your system up wrong and no one is going to be able to give you any kind of an accurate idea of what cfm fan and carbon filter you would need to put all of those items in one line, you will have to do the math. I am guessing that with all of the flow restrictions you will have a restaurant style exhaust would be best for you. Southfloridian posted a source that sells them at a reasonable price. Its a professional looking roof mount, they have a wall mount as well.
All of us are telling you the same thing no matter how many threads you start. Pretty soon you will become like Peter..... you know like the guy in peter and the wolf..... don't be a peter. VV
