Humidity problems
Can I have some advices on how to lower my humidity? I’m having some troubles lowering it since my plant is now flowering. Usually I can’t lower it from 60% while my temps are always on 27/28 C during lights on. I will leave a pic of my setup here. Should I change something?

Ventilation on schedule?
If I put my ventilation on an hour on/hour off schedule to raise the RH (RH when cold is around 30%) and help relieve my heaters a little, will it be detrimental to the environment? I've got heaters on controller, Temp is steady with ventilation on but wil be expensive in winter

RH too low in indoor grow. Solutions?
I'm having a issue with my grow - RH won't go above 20%. With a humidifier inside, full power. Temperatures are between 21 and 25c and I can only think the air extractor is taking too much air out of the grow, as in the night, with lights and fan off RH rise to +80%. Any ideas?

Question about ventilation
I have a 200cm tall tent with a carbon filter connected to an extracter fan/ duct leaving the top corner of my tent. I have no intake air fan connected, although the walls of the tent are bending inward- should I add an intake fan in the bottom of the tent?

2x2 Circulating Fan
What is the best circulating fan for a 2x2 tent available on the european market? I bought a Secret Jardin MO20 oscillating fan, and I highly regret it because I have read several reviews mentioning that it can catch fire. Is there any other good alternative for circulating air?

Temperature Probe. Where to place it?
I use a Vivosun exhaust and control hub. It comes with the temperature and humidity probe. I am curious, based on experienced growers here, where do I place this probe? On the floor or do I let it hang mid-way in the the plant itself?
