Help with box set up idea...

Yeah so this is what I have to work with.... I need help figuring out what size fans and exhaust I should get. Also any other suggestions would be helpful... thanx

i wish i would have designed mine and not just banged it together lol

your design is very good

plan looks good, but it seems like alot of bulbs/ballasts in a small space, you might get too hot. i have a similar size area, with a 400w (air-cooled hood) hps in the flower area and CFL's for vegg. each area has inline fans pulling fresh air in and inline fans pulling air out along with axial fans to move air around (7 fans altogether) and it stays around 75 but on a hot day pulling in fresh air it can get above 80 easily. Of course i run them at night also

What part of the country you in??

Yeah, not sure but I think if a put a 265 cfm blower on both sides of the box it would be enough to keep it around 75-80 degrees. Also I have to filter the air coming in or else I would just use axial fans. So I'm thinking about two inline fans for both sides of the box. If I get one for the flower side it should only need to be the size of the blower sucking the air out. The other side though needs more because half of the air goes into the clone area. This is the problem I run into because if I got something around 300 cfm blower it would cost a lot of money. If I got two 125 cfm inline fans for the left side. I could put one in the veg. and one with the mothers. However I would have to run more duct work and buy another filter. So not really sure. I could cut the lights down but I would like a little extra just in case if I have to put in another plant.

Here's an old post on my setup: https://www.rollitup.org/grow-room-design-setup/37283-before-after-pics.html

I think were on the same page? are you growing in a closet?

re510 your setup looks very well thought out mines a flippin mess lol

This is kind of what I'm thinking about... btw you did a really good job setting yours up with the split in the middle

What would happen if you had more air going out then in?
