thanks for the tips if the plant leaves can be happy at 85 does that mean the ambient temp can be higher than 85°F without causing stress ?

thanks guys i think i will setup a second grow tent after i finish this grow the good news is that i fixed the temp issue by powering only 8 Cobs which according to you is enough and putting a stronger fan in the tent ! i will try powering all the 16 at half the power and see if the temp...

so how many cobs should i run for this tent (4x2x5,90) ? i'm venting in the same room but the ambient temperature remain the same (75°F) because the house has good air circulation good to know right now it read 79 °F with 4 Cobs at 25w as for the watts/space, where i live people use...

yes they are quite nice for that it's not an electronic speed controller, the motor doesn't make a "hum" on it, it's barely audible at low if i increase the speed of the fan the sound of the air will be audible and i want to avoid that thanks bro

it's not a duct fan, don't know how you call them in the US but it's an industrial exhaust fan

the clip fan is off, it is useless, i will replace it by a tower fan and see i thought the leds wouldn't produce too much heat and that a clip fan would be enough but i was wrong the little gray box you see is the exhaust fan controller, it doesn't produce any heat, the drivers are outside...

i will try a stronger fan and see, i'm starting to think the problem come from air stagnation

actually i thought this setup was "stronger" than a HPS 400w but only by a little i never thought that it would pull that much light actually i not going to grow in DWC anymore, i'm just waiting for my smart pot and coco ok thanks bro

2gpw would be crazy, i would be happy to pull half that lol i could decrease the power as i already soldered the potentiometers or i could just power off a driver which one would be the best option ?

i have the B version of the MW is 1300ppfd alot even for 3 plants ?

it's an inline duct fan ( RVK sileo 125E2-L) it can move up to 323 m3/hour but i decreased the speedto minimum because of the noise i don't want to dim the drivers, i want to grow under 400w

yes i think i will invest in a "silent" tower fan

the problem is that even if i run 8 of them (like in the picture) the temperature is still a problem, right now the temp is 84

my drivers are outside the tent the room temp is around 75°F even with the exhaust fan set to max the tent can only go down to 84 degree but i can't run it to max because of the noise maybe the problem is the fan which seem too small to move the air effectively

i'm running the leds at 25w each, i use two 200 watts drivers
