Air flow
Ultravioletanswered grow question 2 years ago
Hey Ghost, nice grow you got going on there, congrats.
Personally wouldn't bother with a carbon filter unless you are worried about legality, smell is generally contained if you are venting outside.
Big side note though if you do use a carbon filter you should at least double the CFM rating of the exhaust fan.
Exhaust - up high (Humidity/Heat rises)
Buy a 15w inline fan and have it suck in the air outside the tent about 1inch from the floor, c02 is very heavy compared to o2 and will gather at the lowest point in the house.
You will certainly still need to keep some air circulation within the tent and prevent dead spots ,a small upward-facing fan spreading around the co2 as it comes in.
Oxygen makes up 21% of the air we breathe
Carbon Dioxide makes up 0.04% of the air plant's breathe
Can never have enough circulation, you want the entire tent just happily "breathing"
Good luck pal!

oscillating fan is a must if you want to grow big strong plants, which produce fat colas.
At veg it will help to form stronger stem and branches, in flower - makes buds goes bigger. I have no phD, but was reading very interesting article about correlation between wind and pollination mechanism in weed or plants generally.
Nice grow !

Hi! It depends on the differences of wind before and after.. if the flow is similar, teorically you can replace, or you can replace only one fan of It is too much strong :)

Ventilation set upI just got my first grow tent- a Vivosun 32x32x64 and a Vivosun 4” fan and carbon filter combo. It came with directions for the tent- but nothing on the ventilation system. What’s best as far as set up? Any tips, recommendations, or photos.? Does it need to vent outside?Setup. Ventilation

Won't Oscillate AnymoreI was wondering what type of oscillating fans that everyone uses in small grow tents. I have been using the Vivosun fans and since they won't last I'm looking for alternatives. In case it matters I'm growing in a 27x27x63 MarsHydro tent.

(Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?
