Ventilation Help please!!!

[keithybaby]

hi there everyone. I am planning my second grow and will be using the secret jardin dr240 (8x8) and would like to know please what fans i will be needing. Will be running 4 x 600w lumatek ballasts with ajustawing reflectors. I was thinking along the lines of 8" out and 6" in or would 10" out and 8" in be better?

Thank you for your help.

Blaze on.... x.

Summer is coming soon, if you have any fear of the tent getting to hot. Go wit the 10-8 combo. If not the 8-6 should be good. IMO I think it's better to overshoot than under when it's come to heat and maintaining proper temps.

Marijuana ventilation fans

For proper ventilation fans, You have to calculate the area of your grow room and then select the fan, The fan should be quite enough to ventilate/ remove the volume of the air in the room outside every 2 minutes...
