Can RH be raised to 100% for short periods of time?

Hey, buddy! 👋😇 High humidity is good for the plant during the seedling stage or at the beginning of vegetative growth. During vegetative growth, humidity should be around 50-60%, but not higher, as the plant will absorb water from the air through its leaf pores, and it needs to drink water through its roots so that the substrate can dry out and the plant can successfully absorb nutrients! You can't turn off the airflow and ventilation! They should run 24/0! If the humidity is too high, it makes sense to get a special dehumidifier (price around $50 in electronics and home appliance stores) and set it up in the cultivation area or outside near the opening of the tent where the air enters! 👌 Good luck, bro! ✊😇
