Options for dehumidifier

Anyone using either of these or familiar? Or other recommendations in the same price range. Currently running a small unit for night time spikes and gets me down to ~60% from 80-85. Need something that will get me lower for flowering as I’ll be switching soon.

I bought something similar to your first link, the Colzer. I think both units you've listed let you get your RH down big time. I think your issue may be the unit is so effective that your water storage container fills up quickly and then the unit stops until you empty it.

My decision came down to the bigger container. The Colzer only holds 9.5 pints. The Vremi holds almost twice as much at 1.8 gallons.

I use a 50pint in 4x8x8. Black and Decker.
This one is on my wish list, for when I need a replacement.

Tried a 70pint. Overkill. Big, excessive heat, and sucked too much elec.

30pint. Weak sauce, no good.

Many variables.

This is what I use in my room.

I need to buy one when I hit hit flowering. Do you all happen to know if the water that collects smells like weed when you dump it out? I'm trying to keep things discreet when I can.

I went with a combo portable ac/dehumidifier. Not sure if they make this model anymore I could only find it as a refurb.

Honestly, I didn't notice.
I suppose that one could take a good healthy dump to mask the odor before flushing the water...

Excellent! I have not noticed any odor myself. The water is not usable though as the materials are not food grade and the water can become contaminated.

still very usable for the plant

Dehumidifier water + Sugar + Yeast = CO2 for plant growth and alcohol for cleaning pieces. I love science and science loves my wallet.

Dehumidifier sizing is such a complex matter with many variables. Ambient RH% and biomass are two big variables , as is temperature both ambient and in the grow area.

During days 20 - 50 ish of 12/12 plants in an ideal situation will transpire at a much greater rate and biomass is increasing rapidly. When the line is crossed where the dehu can't keep up then the spikes will happen big time. So what works well for veg and early flower may not be enough for "peak drink" as I call it during that period around days 20 - 50. Funny thing is the speed up is drastic and it doesn't happen gradually. Same with the slow down. I never noticed this until I was doing top feed peat based mix and coco and using a moisture meter to determine when it's time to water.

So I find dehumidifier sizing to be somewhat of a mystery. I personally have to run swamp coolers to add humidity during veg since our ambient is low and after I hit peak drink I am running several dehumidifiers to keep the RH% below 50.

I tried a larger unit and didn’t like it so I bought the ivation in the link you posted and it’s a great dehumidifier! Has no issue getting me down from 65 to 40 and keeps it there. I can’t use the drain option unfortunately so it fills the 1.3 gal tank in 2 12 hour cycles. Casters are really good, it rolls around with ease. Only downside is the white plastic cover is fairly thin so it buzzes a bit from the vibration of the compressor when running. Still recommend it 100%

I have the larger Ivation ac/dehumidifier combo. As far as the buzz, I can definitely hear mine running but it still makes less noise than my hurricane fans for instance. Not quite as silent as the AC infinity exhaust fans but I had my Ivation running outside of a tent in my living room for a year and barely noticed it.

This 50-Pint WIFI has moved to the top of my wish list.
