I run one that blows over the top of the soil and another over the canopy. Don't see an issue with what you're doing

Auto Tent Help
I’m looking to get a tent for my current single auto grow. I have 24inx24in worth of space and would like something maybe 55in tall or more. My space is clean and climate controlled already. Can I get by with a desk fan for nighttime ventilation without a duct system?

Hey guys. I have an air pump and air-stone for a hydroponic set but i decided to use a “smart pot” instead. Would putting the air-stone in the soil or directly under the pot help in any way?

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

Subterranean fans on 24/7 Y or N?
Was wanting everyone's thoughts on fans on the ground of my tent being on constantly, I want to try an keep airflow as well as make the stems stronger from the movement but always end up getting leaves that get wind damage. Luckily most tends to be where lolipopping will be.

Messy Extractor Install
Bit of a mess this! Though I do have a smell-free grow area now 😇 Would there be any issues with putting the fan outside the tent with the filter inside at the top and ducting going out and down to the fan? Thanks

Is high humidity at night bad for cannabis?
During day, I can maintain the grow room temperature to 75-77'F and humidity 55-65%. But at night, temperature raised up to 77-80'F and humidity up to 70-80% because I closed vents and air condition. Could this effect my plants in long term? Should I open vents at night also?

High humidity in the morning
I’m having a very hard time coping with humidity (goes up to 85%), since I physically cannot get the airflow outside my house for various reasons. I open the window each morning, but could it lead to rottening in the late stages of flowering? Thanks for your replies ;)
