5x5 gorilla tent

5x5 gorilla tent. What is the best fan to reduce heat if no odor control(filter) is required? If I’m running 600-750 watts of lights can i use a raxial s6 to reduce heat or something cheaper? Would one be sufficient as an exhaust?
I hear a lot of people talk about maintaining humidity. Does this vary plant to plant or is there a humidity in general to maintain? Would using this one fan as an exhaust and then a towel inside be sufficient enough. Trying to be cheap, but willing to spend more to do it properly.
Thank you for your input.

If you can afford it, buy urself an ac infinity 8 inch and their 69 controller, you can then set rh and temperature on the controller and the fan will speed up and slow down to maintain these parameters.

depending on the stage of life the plant requires different parameters

I like high humidity 70+% and high temps 28-30c for veg
As we flower it’s beneficial to taper down the humidity towards an end goal of around 40%

I hope this helps

It depends on your climate as to how much air you extract per minute to maintain proper temps.

Same for Humidity, if your in high humidity area you might need a dehumidifier.

If not then the extraction will keep it down , entirely depends on your environment.

Also it's no good just venting that tent out into the sane room, it needs to be vented out of the house ideally.

We all have different environments so there's no one fan oer space to solve all problems for all people

I think the humidity in the area is naturally around 60. I’ll need to vent to the same room, but the room will have air flow to disperse the heat. I wanted to keep open during veg, but close up during flower and use the fan. Is humidity that critical?

You’ll find that the relative humidity in a hot grow tent will be less than the humidity in the cooler outdoors, this is because hot air can hold more water than cold air so that rh% should drop as temp rises.

we also need to factor in the water that will be being used by the plants though so this isn’t always an exact science, my fabric pots release a lot of water into the air from the soil, much more than say a hydroponic drip system with rockwool media

if you absolutely have to vent into the same room as the tent then make sure ur drawing fresh air from 1 window and blowing spent air towards another window, try and keep ur intake and exhaust air as separate as possible. Although I would reccomend long ducting runs or holes cut in walls etc before I’d reccomend doing it this way

Yes the humidity is critical for many reasons, the biggest being not losing your entire crop to rot .

So you'll have to set up and see what happens, but a 5x5 is not a tiny grow and its going to create a lot of humidity.

All I can say is you might get away with it or it could be a disaster.

My first option is always vent up a disused chimney. But I'm lucky that I've never grown in a property without lots of chimneys.

It sounds like I need a dehumidifier in the room, but I also have ac running as well. This will not be sufficient?

Not growing a lot. Just have bigger tent then needed.

I’m the wrong person to be talking to about ac mate it’s cold where I’m at.

maybe if u let the guys know what Btu ac you have and what type, and it’s proximity to ur tent they can advise you.

I mean you don’t NEED a dehumidifier, but I certainly wouldn’t grow without one, I understand this hobby’s not cheap but there are core pieces of equipment that are worth what you pay for them.

bud Rot is no joke!
But having total control over humidity is one of the most important things in order to maximise your potential. leaf temperature and rh% have a very special relationship with transpiration. This is abit advanced for the stage ur at, but if you’re like me you’ll spend all night reading about VPD now lol

leaving tents open is never a good idea, create a proper ventilation system now, don’t cut corners, and it will put you in good stead for the future. If you get it right now you won’t be sat wondering if it’s temp/hum/co2 every time you have a problem

hope this helps mate

I had all sorts of problems with a 5x5 until I vented out. I'm also running a controller 67

Ok I have a couple things I use but my conditions are kind unique during the winter the room with my tents has a wood stove going all winter so its dry and hot. I do 2 things to control my temp and humidity one is I use a humidifier in the tent with coldest water I can get without being frozen. The second is I have a 8 inch inline fan pulling air through the tent and a 6 inch hose that I have attached to my cold air return for the house to draw colder air than the room provides. I am able to control my environment pretty well with these solutions but every setup has its own challenges.
