2 small rooms 1 fan?

I have 5*3 veg and a 3*3 bloom then my fan space and window. I could put a fan on top in btwn or some how and or run a second fan farther away .. I don't want to buy and run and hear a second fan but I want to use a second hid light. Can I use one fan to cool two hoods? Yes I think so but can I have it cool two rooms also with a 440 or 720 cfm fan? As I think about it I could switch the order of my tents to suck and filter the bloom room first then go through the second hood and out my out hole; a window or my room in winter. Any suggestions?

Only thing to do is try it with the one fan for both tents and monitor the temp in each room. Is it pulling enough hot air out of both tents?

I have 225w of flor lights in the 5*3 it's on the left in a corner then i have 600 w hps dimmed to 400 in a 3*3 the filter and beginning of the suck hose is in there it has one passive intake to the 5x3 one out the back. The fan is 200 cfm and the connection to the light hood is not tight so both tents get up to 84 86 easy unless out side or room air is bellow 79 and I'm in socal so that's about 2 seasons. for the rest of the time I will need to do better and add ac. I plan to switch the tents around run a fan 440 cfm to start from the 3x3 sucking through the hood out to the other hood and out that 2nd tent with out sucking any air out of the veg/2nd tent just out to window.
As you said I can try it? I think it will make it so I can run 600w in bloom and 250w in veg. And I will upgrade the fan to 720 cfm and add ac. In summer.
I also have small fans blowing in both tents.

Ya dude it sounds like you got it pretty under control. Seal up your connections for now to improve the air flow. Buy a bigger fan, not that expensive. Check your local pawn shops for good deals. I've sold a couple lights and fans to pawn shops. Good luck bro, wouldn't mind seeing pics of your setup.

Yeah I want to start a grow journal. Did a test . No one responded.. have to go back see if I can find it.
