Can you use Eva-dry renewal dehumidifier in a grow tent and if so does anyone know anything about these good idea or not?

Don't waste your money on that. You need the kind that has a reservoir. Something like this. They make them bigger depending on what you need. I have one a little bigger than this I use in a 4 x 4 tent if I need to. This particular one is under $40.00. It's not very good but it's much better than that Eva-dry thing. There's dozens of different models on Amazon.

I just used that one as an example. I use a bigger one in my 4 x 4 tent flower tent when the humidity gets too high. It kept the humidity within acceptable levels. Controlling the entire room sometimes isn't an option.

You need a real dehumidifier. Get one with a decent reservoir so you can dump it less frequently...or hook the water line up to a drain.
My 45 square foot room pulls 1 gallon of water per day to maintain 50 RH...without it i would be at 70.
And they produce heat. It works for me in winter because i needed the heat but...everything adds to the ying and yang.

Trying t maintain humidity in my tent at night. During day it's great once it hits night humidity goes up. I'm n flowering and it's ruining my babies!

Defoliating might help a lot, trimming off some of the large fan leaves... But yeah you probably should get a real dehumidifier the peltier dehumidifiers don't control humidity swings well

Tents with inlines/exhausts will not allow you to create a microclimate in that space and hence why it was said to control the room.
If you could you could put a tent in a snow storm and it would suffer no ill effect but as such you have to draw in and exhaust air at cfm's/m3 meaning the outside environment is always the inside environment.
For years i have had to control the tents room and there is no work around unless sealed and recorculated with exspensive co2 and air exchange gear normally suited to very huli tech labs.

Use a heater to warm them at night. This helps the humidity spike u see.

Good info! Not many new growers think about this.Tents with inlines/exhausts will not allow you to create a microclimate in that space and hence why it was said to control the room.

I push the basics hard because once new growers realise they have a hard and fast set of rules. Also thermometer/humidity meter placement and wind speed.
Its so obvious but so overlooked - i know i made the same errors when starting and few picked up on it so i feel its worth saying so others can bypass the hell i went through before realising.
Cooltubes are pointless to me to and point out heat as radiation conduction and convection.
