Oh and here are the controllers I use to keep my VPD in check: https://www.amazon.com/Inkbird-ITC-308-Temperature-Controller-Humidity/dp/B01N56KEU6/ref=sr\_1\_5?gclid=CjwKCAiAyPyQBhB6EiwAFUuakoYiJCjVmYemncw13TtaruJPmlFN\_pxM7aAxfzr-j-qa9LnCDbJTGRoCE3cQAvD\_BwE&hvadid=580995958316&hvdev=c&hvlocphy=...
Any mini fridge. I don't think they're too different, also try craigslist/etc. to source them.
You can get something like these temp/humidity controllers, and thread the probes into your fridge: https://www.amazon.com/Inkbird-ITC-308-Temperature-Controller-Humidity/dp/B01N56KEU6
Plug your into the heating/cooling outlets, and configure your temp/etc. settings. If you find you need a heat source, an incandescent light bulb plugged into the heating outlet is usually sufficient.
For the humidity, dehumidifying is typically taken care of by the fridge compressor, so you'll just need to purchase a small humidifier and plug it into the humidity controller to keep the humidity at the level you're looking for.
>you plug both the humidifier and dehumidifier into one unit and the unit controls both to the humidity level you want
So this combo of controllers
I use these temperature and humidity controllers for my cheese aging fridge.
My humidity setup is a little weird, but it works. I have a 1 gallon self filling dog bowl, a terrarium mister, and a usb fan and it keeps the humidity on point even when the fridge is running.
I have some homebrewer friends who use Inkbirds and love it. I was thinking about grabbing this to control the temp and humidity.
I agree that a lot of youtubers and blogs are either "cure meat with only $2!!!!!" or "build a curing chamber for no less then $1,200" which makes it hard to really figure out how to start. It seems to be a pretty big differences out there.
I appreciate the reply.
$70 for the controllers and $50 fogger. Probably cheaper at a store.
Looks like it's the referral stuff that broke it - shortening the link seems to work for me: https://www.amazon.com/dp/B01N56KEU6
Yeah, no prob. Right off of Amazon.
If your humidifier does not have a humidistat and your space heater/AC does not have a thermostat:
AC infinity exhaust fans are known for being pretty quiet. Most peoples grow tents are kinda loud tho.
AC infinity has controllers to help regulate the tent so it's not exhausting too much or not enough.
If you exhaust to the room that your tent is in, your lung room, it can cause problems (heat/humidity) but can be done. It's best to just exhaust outside.
Carbon filters work best when the tent is under some negative pressure (walls suck inward). I don't smell anything until I open the tent up.
I try to support my hydroponics stores, even tho the little things are usually overpriced. Soil is usually cheaper at the store because of shipping cost.
If interested, I highly recommend this piece of kit. (You can purchase them separately if needed) : Inkbird Controllers
Depends on what you are growing. If you're just overwintering citrus, and the outside temps don't drop much below 32, you're probably fine. Starting or growing vegetables you will need at least a heat mat, and potentially something to keep the greenhouse above 40 or 50F. I keep my low temps at 48~52F because I'm an orchid fiend.
Greenhouses lose heat fast. Especially if you use single pane windows. Most greenhouses these days use Twinwall, since it helps diffuse the light, as well as has a slight R value. My tiny little Harbor Freight greenhouse manages quite nicely with a $50 ceramic heater, a dehumidifier, and an Inkbird controller.
these things are a game changer
I have the temp one hooked up to a little space heater and dangle the thermostat somewhere in the tent and it'll kick the heater on and off as needed. The RH one turns on and off my humidifier and dehumidifier too so I don't have to mess with environmental controls at all. That and my automated exhaust fan are my favorite pieces of hardware.
