If a dehumidifier is something that’s needed a lot for your grow I would not cheap out and get something small. Invest the money now to save yourself problems later on 👍

Cardboard box method for dehumidifier
Hi 👋 can anyone tell me what success they’ve had using the cardboard box method for housing their dehumidifier? My unit is heating up inside the tent so much as it works harder during flower to keep humidity levels lower. Before I make the switch I wanted some opinions?

Is it possible for me to take down the walls of my tent and leave the frame with the lights on it to let the plants get more space? I don’t have a way to ventilate the entire closet from an external source, just been ventilating the tent w/ an exhaust fan and carbon filter

Can I close the door of my closet?
My tent is located in a closet kind of room (5x2 meters) and I was wondering if could close the door during the night because the fan is a bit noisy. Will it fill the room with exhaust air/humidity and damage everything inside (the plant, also the clothes that are in the room)?

Do any body have any experience in making your own carbon filter?
Thinking about making one from two steel mesh "ovals" with +-2cm in between. Use some filtration cloth so the carbon don't go through the mesh. And will fill the space between the meshes with activated carbon used for this purpose. Do you think its going to work? Thanks

Best Humidifier for 3x3x2 grow tent and best way to set up?
I’m about to buy a dehumidifier. Finding one with programable humidity levels makes them too big 4 my tent & the small ones can’t be programmed to turn off when humidity is too low. Can I get a cheap one with no controls and manage humidity with my Humidistat alone? Will it work?

Cooling whilst using humidifier outside a small grow tent
I have a small 90x90x60cm grow tent with a VIPARSPECTRA 300W LED. Heat levels are crazy and running a small humidifier with ice blocks inside the tent along side extraction isn’t cutting it. Could I buy a bigger humidifier, keep it outside the tent duct it in to keep it cool?

Grow tent Temperature
I have a 90cmx90cmx60cm grow tent with a VIPARSPECTRA 300W LED Grow Light inside.. How much will an extraction fan and carbon filter bring down the temp inside? In this heatwave my tent is running at 33 deg C, no plants seeded yet. Will the fan be enough or should I get a cooler?
