Building new grow room--ventilation and fan question

Hello--

I'm working on constructing my own grown room and I need some suggestions. I've purchased a secret jardin 150 tent (60" x 60" x 79.2") and an ebb n gro setup. I'm now working on trying to figure out what I am going to do with the ventilation.

I believe I am going to run two 600 w lights, each with equipped with a cooltube. However, i have never used a cooltube before. Should i run separate ventilation through each light, each with an inline fan or can I connect both lights to the same ducting and run a single inline fan? If I did this, would i be able to run a single line of ducting or should i use a t-connector right before the fan and run the lights on separate ducting? In either system, would a 6" fan be ideal or would an 8" fan be necessary?

In addition to the fan on the lights I think I am going to use an intake and an additional exhaust fan for the room, because the air-cooled cooltube lighting system is separate from the air exchange in the grow room and would need to be exhausted. What fan would you recommend for this?

Thanks! Any feedback is appreciated

Are you sure you want to run two 600w lights in there? One would probably suffice.

If you want to use two cooltubes, I would daisy chain the two together. Every bend in ducting reduces your CFM's so a T probably isn't the best way to do it. You could do a sort of U connecting the two tubes with some ducting.

A 6" fan would probably work, but if you are worried about heat issues you could grab an 8" with a speed controller. You can use an 8 to 6 reducer to keep the 6 inch ducting.

Are you going to be running CO2? If you aren't running CO2 you can use the same fan to cool your lights and exhaust your room.

For any fan suggestions, I always visit my local hydroponics store to check their selections. I personally run an Oracle 6".

Thanks for the suggestion--I'm thinking now I might want to run a 1000w setup as opposed to 2 600w's...what do you think? I felt like 2 600's would give me better coverage with 12 plants but then again it may be a bit overkill. I'm not going to be running co2 on this setup, maybe the next. Do you think with a 1000w I'll have heat issues? It'll definitely be air cooled (either way, 2 x 600w or 1000w) but I still hear of people having heat issues. Also, after some reading I decided to go against the cooltube route and I'm going to be using air cooled hanger(s)--any suggestions for these?

Thanks

use this set up but use the hoods inline and a bigger scrubber.
tent.jpghave an intake(out side air is beter inside will work) run exhaust out side. y pipes only nesscary if you plan on useing one intake and one exhause port.

Woah nice thanks AB! So the red boxes are fans right? And the carbon filter is above the hood to the right before the intake of the exhaust? What fans would you recommend to run this ventilation system, and should I do two 600w's for better coverage or just 1 1000w?

Thanks in advance

1khps is good for a 4x4 area. you can use the larger hoods(xxxstremes,xxl mags, raptors,) only problem with these a bit expensive and useing the same watts for a bigger footprint. I dont know how many pots you plan on running but u ccan fit about 10-16 in a 4x4 no problem.

I wouldnt run 600's just beacuse buying two balists hoods exc adds up. 600's are beter suited for lighting up a 3x3 area but i dont really see ac hoods built for a 3x3 footprint.

Also you can run a switchable 1k and run mh for veg and hps for flower

scrubber up top to take out hot air createing a passive intake. Get a thermostat to run this i would think that a 4 inch fan and scrubber would work.

6inch for the hood have a timer with two outlets one to run balest one to run fan

Dude, slow down, lol, please god not another bull at a gate..........
Firstly the Manufacturer of your Tent, Secret Jardin, only recommend 1 x 600w hps for that size tent ( 2 x 600w hps are recommended for the DR240W not the DR150W ), youll kill your expensive tent very fast using 1000w or 2 x 600w, 1 x 600 w hps will cover a 1.2m x 1.2m space, to maximize the most outta your tent and equipment, dont over crowd either, 4 nice juicy resinous plants will be perfect for that space and light, also cooltubes and enclosed hoods are nice, however, highly over rated and really geared towards commercial growers that have lots of space, Adjust-a-wing reflectors ( open reflectors ) work just as well. Grab a 6" centrifugal fan, a 6" inline fan and a fan/temp controller ( PrimeAir Temp controller ), plug your fans in, set your desired temp and fan idle speed and leave, all done....your tent will remain at a constant. looking at around $400-$500 bucks for that equipment, but well worth it.

Well I was going to setup up my intake/exhaust like you had in the diagram. Both would be connected to an exterior wall drawing/pushing air from outside. I have the finances to run 2 600's or 1 1000w, so I figured if I could support the light why not use it as long as I can keep the temperature under control. Planning on growing 12 plants in my 5x5x6.5 area. I just want to make sure before I get everything that my ventilation system is going to work and keep my temps under control.

Thanks for all the input guys!

holes cut in to your walls, windows or what for the intake source and exhaust source

IMO thouy's (1000 watters) produce much denser colas because of the intensity of the lighting.. 2 6's will give you like 180,000 lumens and a thou will give you 145,000... not a bad deal for less power, less startup cost, and easier management..

With one thouey you could put a carbon filter in the top of the room and pump the air straight out passing through the filter, through the one hood and out of the tent.. Nice and smooth with minimal restriction.. then pop a fan for the intake in their somewhere and your venting would be simple and solid...

Just food for thought.

grow tent is going in the garage next to an exterior wall. Figured I'd cut some holes in the wall.

try to track down exterior dryer vents to its just not a hole in a wall with ducting comeing out. you might want to bild a light box in case you have light showing
