What temps and TOO much ventilation?

[md.apothecary]

Everyone says 90 degrees is too hot, what is the optimal temp ranges again for veg and flower modes?

Also... is there such a thing as too much ventilation? I am sitting at 90 degrees in my small grow cabinet I built with three 105w compact flouro lights. I have a fan pulling air through a carbon scrubber... but was thinking of adding 2 more 55cfm fans (one intake and one exhaust) on the box in addition to the 110cfm fan already on the carbon scrubber.

At this point, I am more concerned with cooling temps than scrubbing the air. I plan on setting it up so that if I need to seal the holes up some later I can do so to scrubb the smell... or even just remove the carbon scrubber and scrub the air in the room instead of the cabinet.

Anyway... is there such a thing as TOO MUCH ventilation?? Do you think adding the two 55cfm fans would cool the temps down say at least 5 degrees??

Ambient air temp sits around 78 degrees.

i wouldnt say theres too much ventilation less you got temps droppin into the 50s haha, and as long as it isnt all directed over tiny sproutlings either, 90 f is liveable but it will increase stress and male ratio, 75-87 is good i hear

I am testing it now out of curiousity to see what it gets to with out the scrubber running just to see what kind of temps it gets without any fans.

I mean I don't have an internal fan circulating air in it due to lack fo space, but it wouldn't matter if the air temp is 90, it's just going to circulate 90 degree temps in the box...

Hoping to sustain at 85 degrees... just trying to calculate approximately how much cooler it was with just one fan. In hopes it was about 5-10 degrees cooler.

You cannot have too much ventilation... it'll STINK w/o a filter when flowering tho!
