You are correct. Extracting the bottom can be very beneficial with leds.
Thank you, the problem is there isn’t any holes to extract from on the bottom on my ac infinity tents
Run a duct from the top exit and pipe it with 4 inch pvc to the bottom of the tent. Follow a tent pole down to the bottom. The " air " will now exit the tent from the bottom.
Thank you! I’m trying to picture the duct and pvc going from the top of the tent to the bottom, would the fan just be blowing the air towards the bottom vent ? my idea was to have the exhaust fan sitting at the bottom of the tent on a low speed blowing out the air, but I thought that may be a fire risk, so perhaps having it sitting outside the tent right on the vent to suck out air and push it out. The problem with this would be that it’s not a duct so there would be air escaping. Perhaps putting some kind of duct that matches the dimensions of the vent hole on one side and the exhaust fan on the other.
Ah, now I understand what you mean! So, the long duct would go from the top of the tent all the way to the bottom, where it would be sucking out air. So would it be a good idea to have the all bottom vents open? The vents on bottom have screens. thanks for your replies!

Well, I have a mini split ac in the room. I’d leave the fan running 24/7 at a low level. Would you close all vents and only have that one fan on top sucking out air from the bottom via the duct?
That is what will draw from the tents lower and cooler air. It will not pull as much humidity down but keeps temp up. Are you doing this to keep your temp up while venting the tent?
Yes, I already am able to obtain a steady 82-86 temp in the tent depending my settings on the ac, but I wanted this to conserve humidity instead of sucking it right out. Right now, I still have my exhaust fan on top, on the lowest setting, and it isn’t a problem keeping the tents humidity at around 65-70.
I would think that can be a good thing as long as it is being exhausted out
Others have posted ideas for airflow diagnostics like lit cig along zippers and filling tent with huge vape hits and turning on fans. Never done it. I can track humidity and temp at 4 locations in grow area. I keep controller sensors at canopy level and have pretty acurate growee sensors in bottom area with DWC buckets. On panel which is plant floor and even with light up top. The controller has an outside tent temp and humidity sensor.
Yes I’ve definitely noticed the increase in humidity as the plants grow. What level do you have the humidifier set to for flower? Do you exhaust from the top-out?
I use the ac infinity cloudforge t7, with the Controller 69 pro, set for 1.0 vpd.
So I was thinking about exhausting the way you mentioned and I’m wondering if having the fan sucking air on the bottom and exhausting it at the top via the duct is as efficient as just having the exhaust up top. With the humidifier hose not far from the fan, would it not just suck the vapor right out and not allow for it to flow around like it would if the exhaust was up top? For my small veg tent, the fan is intaking air up top, and blowing it on to the light. The winds are moving the leaves around, maybe too much. I believe the vent with screen at the bottom is allowing a slow exhaust and also a bit of intake of cold air.
Is the 1.0 vpd for flower? What temperature do you keep your room? I have some plants that are just starting to bud and I set them at 1.0 vpd last night. Noticed the bud sites staying wet so I figure I better raise vpd settings. Thinking about getting a small clip fan too but the ac infinity ones are pretty expensive.
I go 1.0 early flower, 1.3 - 1.5 late flower.
