Help me get the right equipment for lowering humidity

bwahah i said 'ambient co2' ... meant say ambient RH conditions...

Hi also für so ein kleines Zelt hast du mehrere Möglichkeiten entweder holst du die ein kleines Gerät für h ter 100 Euro gibt's die bei Amazon. Oder eine. Andere Möglichkeit sind die boxen mit salzen. Suche daa mal das sind kleine plastim boxen wo du ein beutel eingibst dieser saugt die feuchtigkeit aus der Luft. Sie brauchen kein Strom und sind relativ klein und die beutel kann man nachkaufen wenn sie leer sind. Du must dan. Lediglich das Wasser aus der Box entfernen, aber das muß man bei den elektro entfeuchter auch.

youre looking to control the air, you gave your static volume (not really but close enough) of air but not your flow rate like CPM...which means there is nothing anyone can say as far as actually giving devices that is worth a crap on this topic for you considering dehumidifiers are going to be rated based on their flow rate (think liters per day) controlling the humidity in your tent? control your lung room controlling humidity in your lung room? control the temp in your lung room and repeat on and on and on and on and extrapolate out strongly disagree with the TEC advice below; a TEC works in principle by exploiting a voltage drop on a surface and removing said energy from both sides...long story short, your TEC output is just a linear combination of the drop, surface area of the plate, and the energy being removed.....aka any effect you get on the condensing side is going to come with heat on the hot side. past that, they are not efficient and will fail over time about 1000 times faster than any compressor driven device built in the past 10 years. there just isnt a way to meaningfully incorporate TECs to do this job without rippin a tent apart and mounting them into the fabric, then what? like you just dump heat into your lung room anyway and then the air has a higher capacity for moisture and you're just spinning your wheels not understanding what you're doing. just my thoughts

The small dehumidifiers dont work at all. I found a hundred dollar one on amazon thats a 3000 sq ft that works well enough to keep my unsealed garage low as i need. Its a cheap chinese offbrand one but for the price it was the best option for me and now i actually have the ability to lower the humidity

Need more info. What is your ambient co2? Is it consistently in a good spot? do you also have to control that occasionally? You probably have to control the room that contains the tent or wherever it draws air from. If your local climate is great, you could also cosnsider exhausting fromt the tent to the outside. Depending on ambient RH, that might be sufficient. If you have to control the lung room anyway, might as well put it outside and set it at a level that causes what you want inside the tent -- possibly 5-10% lower deending on context.. whatever the offset is inside and out will be roughly the same unless you change the rate at which air is exchanged in the tent, at which you can easily figure out a new offset for the RH setting outside the tent... cause and effect... "pints per day at AHAM" is what you want to compare, not pints per day at saturation. If they don't give that value, it's a bad sign. Energy star rated is a mnimum.. even that is wide range in efficacy. Believe ~2.0-2.1L/kw-h efficacy is top of the line? But even 1.8 is 'energy star' stamped. (i may have gotten the L/kw-h metric wrong but the numbers are right.) Get one for the size of the room the tent resides. Go a bit bigger than necessary and it'll last longer. Go even bigger if ambient RH is often higher than your target RH... on those days you have to fight transpiration and atmospheric RH. Maybe a dehum rated for 2x the size of your lung room.

For a tent that size, you don’t need a big dehumidifier, a mini one will do the trick. Look for a Peltier-style (thermoelectric) dehumidifier rated for small rooms or closets. Brands like Pro Breeze, Eva-Dry, or VIVOSUN’s mini dehumidifier are all decent options for tight grow spaces. Just make sure whatever you get fits outside the grow area, or has low enough heat output if you put it inside. You can also run it during lights-on only if heat becomes an issue. Pair that with a small clip-on fan for airflow, and, if needed, a low-cost digital hygrometer to closely track humidity. If your RH is high and temps are in check, you’re likely dealing with trapped moisture, so increasing exhaust airflow or running a passive intake can help balance things before relying too much on machines.
