Seddenstarted grow question 3 years ago
I need to create an air exchange scheme inside my grower, but I cannot afford to buy an exhaust fan, I have some coolers and I would like to know if it is possible to continue with them and how many coolers would be recommended to put in my grower

The air exchange is so that the plants can transpire and get a fresh intake of CO2. You can use any regular fan to do this. If your only getting a day temp of 20 then you should not run into any heat issues so having coolers will not help. At the current stage your at its not that big of a deal. It will be when your plant gets bigger and starts to fill out the tent. You will need to get some fans to move the air around.

autoflower? if so, just leave tent open and a normal fan circulating air is enough... if photoperiod, can do that for vege phase, but by the time you get to bloom you'll probably need to close that tent up at least at night... you still want some air exchange one way or another.
evaporative coolers? Those are fine as long as relative humidity % is not too high already... don't add so many that you create an incubator for bacateria, mold and other microbes.
my current grow has been as warm as 33C with no problems. Around 30C is a better ceiling to stay below. Warm is good up to a point.

Brauche ich unbedingt einen (Schwenk-) Lüfter in meiner Growbox?Habt ihr schon mal ohne (Schwenk-) Ventilator in der Growbox angebaut? Wenn ja, welche Erfahrung habt ihr dabei gemacht? Ich möchte nur ungern einen Ventilator einsetzen, weil das vermutlich die Lautstärke der Box deutlich erhöht. Schon mal vielen Dank für eure Erfahrungen.

2x2 Circulating FanWhat is the best circulating fan for a 2x2 tent available on the european market?
I bought a Secret Jardin MO20 oscillating fan, and I highly regret it because I have read several reviews mentioning that it can catch fire. Is there any other good alternative for circulating air?

How crucial is an exhaust fan and a carbon filter?I cant find anything in my country as a kit, but would buying them piece by piece work?
Example something like in the photo connected to an air duct and then to a carbon filter?
Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

it's getting too hot. I added 2 fans inside. Do you think I can enable them 100% of the time/all day? Or is it bad for my plants?

I am facing a temperature problem again....My tent reaches 84.2F, which is too hot in my opinion. But my humidity is perfect. On the other hand, if I activate the ventilation, the temperature of the tent reaches 76F, which is perfect, but the humidity level drops dramatically to 35%.

Risk of bud rot with these conditions?My tent keeps bouncing between 55-65% throughout the day during mid-late flower stage. Staying between 24-26 C. I have two fans moving air in the tent and the plants are we defoliated. An in-line fan is pulling air out. How much at risk am I for bud rot? Thanks!

Peltier dehumidifier @300ml per day adequate for 3x3x6 tent? Alternatively, a conventional dehumidifier outside the tent?Peltier thermoelectric dehumidifiers extract 300ml of water per day. Weak compared to compresser units, small and use less energy. Is it enough?
Would a conventional dehumidifier set outside of the tent near the intake be effective, or does it need to be inside the tent to worka year ago
