Thinking of joining another drobe to mine

[scorpion]

I have a drobe with passive intake and 4 inch extractor and I was hoping to connect the other straight to it without having to buy another fan/filter, am I right in thinking the 4 inch wouldn’t be strong enough to work
Cheers

Just thought My fan is the rhino twin speed one and I normally have it on the lower setting so could turn that up, the other drobe will mainly for drying but might want to grow a plant in it at times

Probably be ok mate, trial and error. You can work out roughly by gettin the area of the 2 grow areas and calculate it to match what fan you need. Havin said that I have a 6 inch rvk in a 5x3x7 ft room and it sucks the door in on 1/5, no smell either. I keep it on 2/5 to be sure. Your areas are quite small. If it's 2 sealed rooms though you may need a Y and another filter for the second room. Depends how you're settin it up, maybe stick the filter half in half out of each grow space. Probably be some better ideas though

Just figure out the square footage like MrC says and you should
know.

Hmmm i have 1.2x1.2x2 and extraction fan have been running on 400m3/h. I could switch it to lower speed and its 220m3/h but not sure if its getting too hot because i noticed yesterday when i have window open grow tent gets kinda cold also. I am fitering into room so i think i have to keep it open every now and then to get better air and cool it down

LxWxH=sq.feet

Then see how many sq. feet your fan does a minute.

Yeah, need to see the sizes we are talking about first...
