Sadly this is not it... (humidifier by SF)

Tested the Spider Farmer humidifier and I have to say: I'm not a fan of it.
It beeps everytime you push a button, like an old microwave or nokia phone.
When you empty it some water runs out of the tube, where in the user manual it sais you should not get water in.
The mist is cute but doesn't really do anything in a well ventilated environment I added 2% RH after an hour letting it run at 95% Target.
Should have known this was too good to be true with 25w, save yourself the 100 bucks, folks.

cheers, 420

Do you grow in a room, or tent? Sq.ft?

Tent, 8x4.
Blew the mist directly at the RH-Meter 1m away for almost an hour.
Had my little vent running in the tent at lowest setting (sleep mode).
Have good extraction tho. If I get my room to about 50% RH with a big pot of water on the stove it also goes down to 30 in 2 hours.

Not sure what the normal ambient humidity is in your neck of the woods. I live in semi-desert area, and so it's common here to be 20-30%rh at times. I grow in a 4x4 and during early veg, so not very much plant matter, I run two humidifiers so I can adhere somewhat to VPD. In seedling and early veg, I try for a VPD of 0.8. With AC Infinity 4" inline intake, 6" exhaust running on 1 or 2 setting, I am able to get there, but humidifiers are running almost full blast to do it.

My ACI humidity box draws up to 140 watts on setting 10. Highest setting used on was 4 of 10 When pushing seedlings and early veg at 75% RH. It was in a very small tent but I am moving it to a 4x4 as soon as drying is complete.Unless I get lazy with fans and positioning it stays 1 up and 1 down. It was also almost 2 times the cost

You are correct that the math was never going to work out. 25 watts is just not enough to do any real work.

I think OP said yes, on lowest setting, and I do also, on 1,or 2. Air needs to be exchanged, unless you are running sealed w/CO2, no?

My take as a new grower that did a lot of research you def need air exchange when you run the highest humidity, but this is during seedling and early veg. At this time in the grow a cycle for the duct fan works fine. 2 on 2/ 1 on 3 off whatever you can stabilize the humidity with. This will slow the humidity venting into the lung room. Also reduces water requirements for the humidifier and slows the lung room humidity climb in smaller lung rooms.
Later parts of the grow require lower humidity and usually higher temps making humidity control easier with larger air exchanges.

Are you saying your are VENTING at the same time as trying to add humidity?

So ure saying everybody who has a humidifier doesn't have any air extraction?
I don't see what turning it off would do since I have to turn it on again at some point and then the moist air is gone just 5 minutes later.
Anyways... this is maybe good as an inhaler for a grandma who has asthma or something. MAYBE for a seedling tent.

I think you get it, but yeah the slower/less often you can run the exhaust, the more that humidity is going to stick around inside the tent.

In general, if you have a tent-in-a-room situation, it's probably better to put the humidifier/dehumidifier in the room rather than in the tent. It'll save space inside the tent and make your environment more stable overall.

You could also try putting the humidifier outside the tent but right next to the air intake, so that you're pulling humidified air into the tent, rather than pulling in dry air and trying to add humidity to it before it gets exhausted out.
 
Like I said in a previous post, ambient humidity around me is low. I'm only in a 4x4, and need two humidifiers to hit a VPD of 0.8 in early veg (65-70%rh), and still maintain some extraction with inline fans on intake and exhaust. I suppose with young plants you could run extraction on an on/off cycle and maintain more humidity, but I'd rather keep more ambient CO2 flowing into the tent, continuously exchanging air. Seems to me, running on and off extraction would create more peaks and valleys in temperature and rh values, whereas continuous extraction, even at a low level would keep the environment more consistent.

Also, 4x8 is double the size of my tent. Not sure on an acceptable solution in your situation. 4 humidifiers? Not sure that is realistic either. Someone else with a setup closer to yours should weigh in on what they do. Maybe just grow at lower humidity. Not something i want to do. My 2 cents.

I tried 3 different humidifiers in the tent and all failed because they are not meant for small spaces and for operation on a demand schedule. They are made for single rooms and for raising large amounts of air to a steady humidity.
Commercial humidifiers unless that are ultrasonic have a spool up and spool down event that is hard to control. Using an inkbird the closest I came was 3% up and 3% down, obviously not very good. I did not have the option of humidifying the whole of the basement so a purpose built humidifier running on a controllable app fit the bill.
My larger tent is in a much smaller room now and I will be throwing away all my data and figure out 4x4 tent in a 12x10 room.
 
Yes, my humidity does fluctuate at least that much at times. I only have a controller that runs my inline fans and set them to the levels I want, but it isn't perfect. It doesn't appear I'll be upgrading to better, more precise equipment anytime soon unfortunately.

Do you run extraction 24/7?

My only comes on when temp or humidity get too high.
 
On another note I looked up professional humidifiers that could handle 250m³/h they are equal in watts (250) and the size is about 2-3 times the size of the SF unit.

Might as well put a pot on my stove again when it's too dry and pray for rain every now and then.

:rolleyes:

I think it would A: turn on and off too much and B: I don't like my room smelly.
I don't even use the TC from the fan tbh, just let her rip 24/7.

What's too much? What's the difference if it turns on and off intermittently, or runs continuously?
Mine runs ~every 2 mins.
You could be standing next to my tent, blindfolded, and never know I had bud growing.
