Hello I just recently finished up my box and am now testing it to control heat and humidity. I am using a 300w mars hydro LED (~150-170 draw power). the size of the box is 1m tall, 1m wide and 0.5m deep, with an extra top to place the light. it is 0.6m^3. My passive intake hole is twice the size of the hole my exhaust fan is located. At first when i had my light on, my oscillating fan and my exhaust fan the temp quickly rose up to 33-34 celsius and then stalled at that point. I then tried stopping my oscillating fan and shortly after the temp fell down to 28-29 celsius. However i would like to the temp a tad lower, and need suggestions on what i could do to achieve this? Maybe i should make the passive intake hole a bit larger? I kinda dont want to add more exhaust fans as this will make it harder for me to controll humidity.
