0% humidity

[PJ Diaz]

Yes I understand that after watering there will be some level of humidity. My question was regarding the possibility of flowering cannabis with very low humidity levels (1-10%).

You'll want to run lower temps than you would in high humidity.

Um, was that your question though? I'm seeing that you asked about 0%, and you said that 0% is your friends RH. Oh but you obviously meant 1-10%. Gotcha. Bahaha. Its okay. We all ask stupid questions sometimes.

Not literally. It's a hypothetical question to see if low humidity affects a plant when flowering. It's okay. Not all of us have the ability to read between the lines.

It's not that it's impossible to flower in low humidity, but if you're not giving optimal conditions for growing, don't expect great results. Limiting factors come into play, and humidity is one of those factors.

Makes sense. It’s been hard for me to grow in a small closet but I have still been able to make it work somehow. This is my last plant.

At that level of ambient RH, I would definitely look to incorporate a humidifier and get a PulseOne. The Pulse is the brains of my setup. I use an Inkbird humidity sensor to control a "reptile humidifier" that has twin outlet hoses so I can direct the vapor stream wherever I need (2' x 4' tent can get pretty full).

Is 0% humidity in flowering okay or not?

I'm inclined to a yes, as I found someone who grows absolutely massive healthy plants in a high altitude desert climate with 0% humidity through flowering.

That's the guy, and there are others too. I came to this because I grow in a closet as I have no other space to grow in. I had problems in my last grow with bud rot as there is no ventilation besides keeping the closet door open.

Without circulation it's problematic at night when the door is closed. I want to use a dehumidifier for my next flowering phase but as the closet is small I'm sure it will reduce my humidity to 0% which is why I'm trying to figure out if it's okay, or find some other solution.

Why is this an 'all or nothing' situation? A dehumidifier set for something like 35-40% in flower will be a good point without generating all the extra heat of running the thing all the time to get down to 0%...and you'll also have a closet that's 100 degrees, which would be more of a worry to me. It sounds like there's air circulation issues at the very least. I've flowered in that 40-50% zone and never had bud rot issues due to humidity.

I haven’t been successful finding dehumidifiers with adjustable settings for humidity in my price range. I was looking for something that costs up to $100 but the ones I found are around $250-300 and they are sizable which also doesn’t work because they don’t fit in my space. Yes there is no air circulation, although I leave the door open during the day and temps are always good. I need something to control humidity especially during the night.

For any that don't have on-board humidity level sets, you need a controller with a sensor. They're like 35$.

I’m looking into it now.

Okay problem solved, thanks. That’s all I needed to know.

They are 50% off in the inkbird store on Amazon.

Pick a dehumidifier that has a physical on/off switch that can be set to 'on' and doesn't reset to off when it doesn't get power.

Good point.
I bought a Waykar last year because it's pretty compact. No complaints.

Thank you. I just got an inkbird with a huge discount and a dehumidifier with a physical on/off switch. Now I don't to worry about humidity rotting more of my buds.
