Ventilation help needed please guys

[Enjoil]

Hey 420 family, I got a couple questions about environmental control. What are you using to cut off fans and ac and all that mess. I hear you guys talking about Inkbird controllers... is that still where I should be looking or is their something else I should check out... I got two more can fans and another carbon filter and a big ass portable a/c. I just need help setting all this expensive crap up! Lol. please. I don’t want to set it all up and have to take it all down and do it differently... thanks guys and Ganja mamas!

For the AC operation I use a Willhi digital thermometer controller.

My fans, i keep on a timer and ultimately would have them go off a few minutes after lights off.

That Willhi also has a R.H. meter that can be used, which would be keen for air exchange.

Just my .02

Thanks patient puffer. So I plug the ac up to that then it kicks it on when temperatures get within a certain range? Is it really that simple? And where did you get yours at? Online?

I got my at the "zon". You can set parameters to turn on and shut off.

I set my high temp at 80° to turn on and I set the low at 70° and that's when it shuts off. I keep my meter/probe in the grow box, so even though the unit and control box itself are outside the box, it still only functions by the environment in the box.

It was originally bought to keep the AC on for our animals in the laundry room. Turns out it works excellently for growing.

I leave fans and ventilation on 24/7 never turn them off.

Reason is: Transpiration and stealth.

Lights I use a 20A pool timer heavy duty. It shuts off fans blowing on power supplies and lamps. Everything else stays running.

It depends on your needs. I would see how your environment behaves once you have your lights and air exchange going. Inkbird and Govee both sell bluetooth temp/rh meters that graph it all out on your phone. Maybe not necessary but its convenient. I order inkbird humidity and temp controllers right from their website. Shipping is quick. I leave all fans (ventilation/circulation) on 24/7. I don't have a problem with high heat where I am, I actually have an oil heater in my tent on like 24/7. But I use a controller to turn my humidifier on when it drops below whatever rh I set.

I would expect to be dialing things in and changing it around for a while though. Its a process

Hey Enjoil,

I’m low tech because I can get away with it in my space. No controller at all here, no extraction fans either. Just a fan or two running 24 X 7 and another fan or two on a secondary timer. This is for 12 X 12 room but only using part of that and lights total about 620 watts of led. I ramp up fan usage as seasonal changes occur so in summer I’m running at least 3 or 4 fans depending on weekly temp averages.

Anyway prolly not what you were looking for but that’s my deal. Heard a lot of good about inkbirds and also ac infinity fans which have their own built in controller

Thanks for trying to help bro, my situation is a little tricky.... hopefully I will find a method to my madness soon. I want to supplement cO2 eventually and run a sealed clean room. Till I get the tanks Ima continue to vent out the spaces.

I was pretty confident my input was as useful as tits on a brahma bull... but wanted to give diversity of opinion. Anyway ah yes co2 would be really nice, you will get it dialed in!!!

I do the exact same thing for the same reasons.
