new grow room 250w or 400w hps?

Well, the only differences I see in what you are doing is using the axial/duct booster fans and that "box" on top...

I can imagine that it adds considerable drag to the airflow...

And I would bet that you would get more intake if you removed that fans and had proper sized holes...

I think I'm going to try hooking up an axial fan in the 4" passive intake hole to help draw the air out of the flower room. When I close the doors the axial fans in the other chambers spin from the suction so I thought for sure the 465 CFM fan would be powerful enough on its own. Hey, sorry about the previous pics, I didn't realize how small they were.

The axial fan will actually block the airflow... they just get in the way...

Make that hole bigger for one thing...

another consideration would be to isolate that box with the ballast...

Use your axial fans to exhaust that area and use ALL cfm of your big fan for flower room...

That's an excellent idea!:clap: I'm going to move things around tomorrow. If you wouldn't mind, I'd really appreciate it if you would also follow my grow journal. I haven't had anyone offer any good advice on my heat issue and it would be great to have a pro to turn to when problems come up.

BTW ForcedInduction, sorry I kind of took over for a bit, that wasn't my intention when I posted my experience with a 400 watt hps but I hope that people who read your journal are able to learn from my mistake.
 
I am not a pro bro...:lol:

I am just a newb...

I just followed proven recipes... that is why my grows look so good...

But I am just a copycat...:lol:

I'll take a peek at your journal...

But I subscribe to 659 threads...:razz:

Feel free to drop by my journal with your questions... that is the only reliable place to find me...:eyesmoke:

yeah its pretty cool. instead of using plywood to block out the light, i used black and white poly and velcro.

i'll post up the dimesions later when i open it back up but its a good 8 inches deeper than it was. still the same height and width.

i also scored a 70w hps streetlamp to hold me over till i get the 400w. then it will go in my veg room.
it took a while to pull it apart and rewire it, but it was worth it. i put 6 feet of wire in between the ballast and reflector.

My setup is currently a bit different than your drawing in that I have my carbon filter and fan inside my tent. Hot Air/Smell is sucked from the inside of the tent through the filter, through the cool tube, through the fan and out the top vent.

I have a 250watt right now in a 20x36x54 tent and am considering going up to a 400 watt. We do a lot of LST, so I'm not expecting height to be an issue, but if it does become one, I was thinking of moving the fan and filter outside the tent to gain some height back.

Have you noticed any difference pushing air through your filter vs pulling it?

Thx
 
Go for the 400, they're almost the same price as the 250 but work on the air ventillation system, that's gonna be the bitch!
 
thanks, i'm going for the 400 and the cooltube.

weellll i just called up HTG supply to place my order, and they are SHUTDOWN till next week!!!! WTFFF???

From the looks of their site, I'd say they're back up and running today.
