Hello all, I was wondering would a VenTech 440 cfm 6in, inline exhaust fan with carbon filter be enough to control heat and smell? What would be the minimum need for an intake?
5x5x6.6 grow tent, newbie. Intake/ exhaust

Do you own the ventech or you're planning on ordering one?

Not sure, on how many plants yet, may do 6-12. Not sure I want to do a scog yet. Not really planning on using CO2.

We need just a little more detail. Where is this room going to be located ? Main level house, basement, garage ? All of which would require slightly different needs in environment control.
The ambient temperature of the grow room (temp of room surrounding the actual grow room/tent) will affect the ultimate temp of the grow room itself.
That being said, there is a way to control the ambient Temps as well. if you can pull the hot air from the light/hood and grow room, and send that air to another portion of the house, you should effectively be removing most/all heat being produced. Which of course would result in little to no temp increase.
On the other hand if your just pulling air from the tent and exhausting it into the ambient enviroment, your basically just prolonging the issue.
But to answer the question directly, yes that fan will work, if you exhaust correctly.
For the filter and smell, that's highly strain dependent.. But golden rule, better to be safe than sorry.
If your still debating plant numbers I can give you advice. Although it will always be trial and error when it comes to canopy management. ALWAYS. No matter how much you read, experience is always wins.
Anyways, the most ideal way would be to do 1 plant per square foot. Only veg for maybe 2 -3 weeks tops depending on strain. No topping, but maybe some lollipop (trim lower branches) to reduce popcorn nugs. I like this 1 plant per square foot because regardless of the room size, you always know the veg time, and the training for each plant is minimized. This results in less chance of untamed bushes producing ounces upon ounces of larf. If 25 plants is too many I would suggest 9 plants veg'd for 4 weeks. Topped once early in growth and lollipopped.
Whatever you choose, just remember to take note of the veg time, snap a picture with the plants before they get put into flower so next round you have a good idea of what your babies grew into so you know to to train/prune accordingly.

Location will be on a main level house, strain for the moment will be bubblicious. Right now I have a air cooled hood.

You will be good with that fan

Is there any others that would be recommend? How many cfm should the intake fan be? I have a small 4in 100cfm, it should be larger correct?

With 1000w HPS in an air cooled hood, in a 5x5 tent, you're going to want more than 440cfm to remove heat from that tent, IMO.
If your hood is air cooled, what fan do you have set up to move air through it? Where is the heat going? Try to keep the hot-air from the hood from making its way back into the tent.

So, an air cooled hood is kinda sealed right? If i hook a small fan that pulls air from outside the tent pass the light, and out the other side of the tent that would cool the light down a little, right? If so, how much CFM would be needed? That with a say 440 cfm fan with a carbon filter to exhaust the hot air from the top of the tent, should control heat pretty good, right? How much cfm should be needed for the intake? (This as been the only part, i've been a little confused about. Thanks
