Humidity

ive recently harvested my first of 4 plants and its been curing now for a few days its quite nice, a bit fluffy due to lack of a circulating fan and lumens for amount of plants but ive now addressed these issues and am overall very satisfied with my first grow so far, the problem that has plauged me through the entire grow is low humidity, it doesnt even register on the hygrometer, ive tried damp towels/ shallow bowls/trays of wet pebbles, and bought a humidifier about a month ago it takes forever to get the humidity up then if you dont refill and restart immediately the humidity just gets sucked straight back out, its only a slim growspace (D x 1', W x6', H x6') so i cant put it in there with all the electrics, how crucial is high humidity, and how would it of affected my plants so far and is the only solution to keep up this regime of damp towels etc?

a misting system maybe.........

the more sealed your room is the better it will be at holding in humidity.

do you have constant intake or exhaust?

there is a 4" in line fan with rhino filter attached directly to it then a 2' run of 4" ducting which exits directly through external wall no bends or restrictions and runs 24/7, i havent made any intake holes yet but have been tempted to recently though i thought it was drawing in enough air through gaps, also i wasnt sure how this would affect temps, may have to just drill a couple of holes and see what happens was worried about light leaks though.

what are your temps like when your not running your exhaust?

im not sure ive never turned it off since it was fitted for fear of smell, its always been a bit of a nightmare trying to measure the temp being such a small space if i put the gauge at very top of plants its like 80, but in the same place with a cardboard shade its 75 and on top of plant pot its 70,im just going on info found on the internet/forums but theres so much conflicting info its hard to know if im gettin it right or not.

just done a quick search on misting systems, was thinking i could prob knock up a diy version easily enough, still a bit worried about the water/electrics in such a tight space though what do you think?

if you bring in cooler air then the humidity should go up! so try putting a passive intake in. or you could try running your extracting fan less when lights go off, so put it on a timer to come on for say 20 mins every hour, your humidity is always higher when the lights go off.

right reding can be gotten at plant height not directly in the light. often in small rooms you have to wing it and tell by whether your plants are burning or not lol
