THE RH WAR & THE PERILS OF FEEDING 'TIL RUN-OFF

(coco/perlite, 4x4 tent, various strains photoperiod, 3g fabric pots)

I have come to realize that my out of control humidity (~80%rh) issue is a symptom of watering the plants until run-off. Having been led to believe the 'little and often' method will result in salt build up and nutrient lock-out i had been watering thoroughly each time and testing the run-off ph and ppm levels. However now i am in the first weeks of switching to 12/12 light cycle and the plants are growing bigger i am considering changing tactics in an attempt to thwart my ever spiraling rh% by watering lightly each day. It has also been my experience that watering til runoff every day was much too much of a muchness and no doubt the reason why my humidity spiked in the first place. It also seems like letting the coco get almost completely dry fore feeding makes the plants happier although have heard multiple growers warn against this so am pretty unsure on what is right vs what is optimal vs what is more efficiet vs more work/effort, etc etc.

I should add that i am pretty entrenched in my 'won't buy a de-humidifier' position and not just because i already went waay over budget on this grow. I have read so many accounts of growers shelling out for machines which barely make a difference unless you go commercial grade or they're installed to work with an a.c. unit (no AC units in Ecosse anyway) and my tent is fit to burst with plants of slightly varying ages and sizes (why yes i am a moron, thanks for asking) so my thinking is a dozen water-logged trees sweating buckets in a tent will be an almost insurmountable for for any dehumidifier i could afford anyway.

tl dr - OP channels Sherlock Holmes & Cpt. Obvious to blame waterlogged plant pots for high humidity problem in grow tent. Clearly shilling for Big Humidity too with all the dehumidifier hate speech.
