Auto flowers no, but the set up won't likely work for a photoperiod.

Throw out one plant?
Is it productive to kill one plant if the rest of the plants are filling out the room just fine and to promote ventilation and light penetration? I have one plant that is way shorter and behind the others due to genetic problems.

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!

Humidity
I’ve been seeing a lot of people have a much lower humidity. I’ve been keeping mine at 75-80 with around the same temps. Is that to high?

High humidity
Hello. 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.

currently using a 200mm inline exhaust fan that has 914 m3/h(537,9 cfm) max currently using it at its medium setting of 792 m3/h(466,15 cfm) and using a 125 mm inline intake fan with only 330 m3/h (194,23 cfm). Should I get anther intake fan or should I put the exhaust to low 680

Smelly room, with filter should I be able to smell flowering buds?
I have a 3x3 grow tent with a 4” fan and filter. The filter is in the tent and exhausts into the room. I taped the filter to the line and line to the fan so no pinhole leaks. The fan is rated for 198 cfm. I have it on low because when it’s high the smell is worse.

Best way to cool your tent/ growbox?
So I’ve built a custom growbox using an IKEA wardrobe, air vent for intake, two circulating fans, carbon extractor exhaust, and a 600W LED grow light. Temps average at 29 degree Celsius with the lights on full, is this too high? Best way to bring the temps down? Many thanks!

So has anybody used these cordless mini dehumidifiers in their grow rooms? They’re small units that u charge over night every so often when the silica changes colour? My grow room is very small so an electric dehumidifier wouldn’t fit and I’m struggling to keep humidity down

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
