Hey redrain and littleamsterdam.. are they noisy? Quiet?
How long have you had them? will they work on a timer?
and RR> thanks for the thought on night time heat load..
something else I didnt concider.
Compost.. RR/LA, thanks...
if the fridgidaire works on a timer.... I'm in.
they are virtually silent, mine is brand new, but I have seen em work for years and years. l have even seen little bits of soil fall into them and look pretty beat up, but they keep on going. they have a check valve in the output nozzle, so no water flows back as well. They will definitely work on a timer, but I leave mine on 24/7. When the water level gets to the top, the unit starts to pump.
i would say that is sufficient. are u running a sealed room?

I just got a 70pint and love it so far. It is so less noisy than the lg it replaced. Good thread op

Thanks for this thread, compost.
On average, about how many gallons per day is your dehui currently pulling?
(I'm in the process of sizing my condensate reservoir--I'd like to be able to leave it running for 72 hours.)
Oh yeah, and because of this thread I googled "humidifier condensate pump"; easier and more compact than making my own.

I've put the dehumidifier on top of a 25gallon tub...
how much will acumulate, depends on your situation..
if you live by a lake or an ocean you'd get more accumulation than if you lived in a desert.. etc...
in a 1600sq ft home in Florida that has central air kept at 72F, 50-55% RH... it doesnt take much out.
Usually add more RO into the tub, than take out condensate..
The tub, then feeds the humidifier... for lights on time..
some times I'll have to add RO or old condensate to the tub, for the humidifier,
and some time, take some out and save it to add later..

My 50 pint is pulling out about 2-3 gallons a day during winter. During summer I can see that jumping up a lot. Yeah a condensate pump is the way to go. I am still trying to figure out a way to use one of those inline with some sort of water sanitizer.
Potlatch there is 2 huge factors when it comes to how much water your dehumidifier is gonna pull from the air.
The first is how well your room is sealed esp. when the lights are on and your air cooled hoods are running. A poorly sealed room will have less air moisture in the winter and a TON more during the summer if you live anywhere that gets hot and humid.
The other factor is how fast your plants are transpiring water. The more green in the room the more water that is gonna be used and disposed of by the plant. Also the temperature of the room will play a role in this. A C02 enriched room thats 85 degrees will transpire a lot more water then a room at 75.

Compost, here's a link to VPD (vapor pressure deficit) < Humidity vs Temps, or >transpiration.. great article^^^..
Yeah that is a very nice link. I am gonna read up more on this I might change my lights on humidity esp in the hotter months.

GD article is telling me that I've NEVER had enough humidity during blooom..
even with what I concider very good yields.. now there's a humidifier (Commercial Grade) that when outside temps & RH go down at night (outside) it can pump 3-4 gallons of RH into the room at night (Inside the tent) keeping RH at 50%<60%..
I will admit that ther are way more tricombs than b4..
Hey, by the way,what do you use for photograph software?
I used to use MS photoshop, comp. died, that'sa the end of that but cant find a simple SW photosho that I can navigate..

I am a simpleton. I just take the pictures on the digital and upload them right to the sight. I am wary of any step that might leave more traces of what I am doing. One day my wife changed the settings so pictures that I uploaded onto the computer automatically uploaded to snapfish. Thank god I noticed and our albums were private but....
To deal with a summer room that is sealed I would say the minimum dehumidifier you will want has to be at least 25pints per day/per 1k light. For those living in low humidity areas you could probably go alittle lower. At those settings during the hot summer heat your AC will still be pulling water also. One thing to keep in mind is that if heat is an issue for you then you should oversize your dehumidifier as much as possible. As you step up in the pints per day the efficiency goes up and there for you produce less heat in your room. My 50 pint is all I need with lights out to keep my room heated down to below 15 degrees with just 4 inches separating the room from the weather.
One thing I have found helpful is once about halfway through lights on I will turn off the CO2 and come back 15 minutes later and let the room air exchange with the outside air to drop the room temperature a ton and lower the rooms RH to give the dehumidifier a nice little 20 minute break or so. Also right at lights out I will do the same. As the room cools there is gonna be alot of humidity that needs to be removed. Instead I drop the temperature and humidity in the room. Just things I do when I am bored and around the house.
