Just had a quick look and that looks fine to me, I like to put the fan on a timer to give it a little break a few times a day. Unless it’s too hot with lights on, then I will have it off for a couple of hours while they sleep.

Smell problemI have a small tent from airontek, not the best in quality with a carbon filter and extractor inside the box, but the smell outside is too strong. When using carbon filter do i have to expect to have (almost) no smell or maybe Im doing some mistakes? The smell is very strongSetup. Ventilation

High humidityHello. Even with a dehumidifier and a 24-hour extractor, the humidity is still above 70% and one of the plants is almost in the flowering period. Can I add expanded clay on top of the vase to see if it lowers the humidity or putting more perlite will solve this? Thanks.Other. General questions

My exhaust fan has no speed control and drops the humidity. I have my humidifier on almost full blast(not full blast because of i dont want it to overheat) a wet towel and a bowl of boiled water.

Grow tent TemperatureI 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?Setup. Ventilation

Circulation / ExhaustGetting ready to install carbon filter; found myself wondering if growers typically leave their filters/exhaust/fans on during dark periods?
Up to this point, I've had everything on one power-strip/timer: circulation fan, exhaust fans, and lights. Should I keep anything on 24/7?Week 11

I made a firebomb?Is it a fire hazard if 5v computer fan is jammed and the power is on for 2-3 weeks?
I'm far away from home and I have camera in my growbox. A tape has fallen to the fan and it is not rotating. Can it heat up so much that fire starts? Should I drive 1600km for that?Setup. Ventilation

High heat in greenhouse, how hot is to hot?I built a 16x20 greenhouse with dual vents and a 24” exhaust fan. I hit a max of 122 (it’s 92 outside). I typically reach 105-110 on regular days. Everyone looks happy other than an nutrient burn issue. Can weed plants handle this kinda heat?Setup. Ventilation
