in a 4x4 grow tent I have an 8 inch oscillating fan blowing over 2 plants and a 6 inch clip fan blowing behind the plants from above … should I have a fan blowing under them also … plants are in flower and are fairly bushy ![20190321_130639-2](https://global.discourse-cdn.com/growingmarijuana/original/3X/4/6/461d5c1527556753a23b0d23d14f565d06d26774.jpeg) ---

Do you have an exhaust fan if so 8 inch and 6 inch you should be covered good with exhaust fan pulling hot stale air out. ---

have 6 inch exhaust fan that runs at 50% when lights are off but only runs 15 minutes of every hour in the day so I can keep temperature up to about 23 c … tent is in basement … no insulation on walls … keeping humidity at 50% or lower most of the time ---

When the plants get more mature and starts putting off more odor you may have to run the exhaust fan 24/7 in order to keep negative pressure in the tent to. Control smell. Good luck ---
