Maintain 50% RH in Socal?
Bonerdonor99started grow question 3 years ago
So if it's 1. LIGHT 2. WATER 3. ENVIRONMENT...what are you doing indoors to maintain ur environment. I'm in week 2 of Flower n since I cranked my lights up to around 75% (850 PPFD) temp is ok (72*-85*) but I can't get down to 50%. I can keep it around 57%, but nites it goes up

I live in SoCal. I run my AC with 2 windows cracked slightly on both sides of the room. 1 T6 intake on low on the floor of my tent, 1 small fan moving the light heat away from the canopy. 1 T4 exhaust on high directly next to my lights to pull heat.
Ac is outside the tent. Seems the air flow goes into the tent, exhausts up to the ceiling and runs out the windows. My temp stay from 74-85F (85 during a heat wave of 100+) my RH stay between 45 and 55. Day to night. If my windows are not cracked my RH goes to 65 and stays there. I do not use a dehumidifier at all.
Probably not helping you out but it's what I do. Smell isn't a problem for me either.

I run a dehumidifier and oscillating fans in a 10x10.
It’s a battle cuz if you bring in a dehumidifier- your temp is gonna go up sharply too to drop that RH. As long as it’s not above 65% at night I wouldn’t worry too much

Umm check out VPD charts on google for flowering.. shows you the best range for temp and humidity for plants.
I’ve realized you don’t need to be down super low RH in flower. I’ve had great success around 50-60 RH and upper 70s F
As long as you’ve got plenty of air movement and fans moving the plants you’ll be good..

Even with a AC Infinity T6 inline fan w/digital temp/humid. control I found that at lights out my RH rise was substantial (not a surprise since RH is humidity in relation to temperature)...the easiest thing for me was to add an extra large fan (box fan) in my grow tent that angles upwards that's on a timer to coincide with lights out. The RH still goes up but now only to 60% instead of 70-75%.

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.

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?

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

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%.

Carbon filter sleeve needed?I use the carbon filter on the exhaust side. On the intake side, I have a dust screen mesh.
The tent is quite clean so that’s why I don’t see the need of the pre filter. Would also probably load the inline fan a bit too.
What’s you thought?
