well. as far as i know its a fluke! its been up over 50% but not much more then like 5-10%. i have been told, and please do not quote me on this..."to water coco everyday" from a grower in which i honer his opinions. not everybody agrees though, and a part of me doesn't either. but!! i thought i would practice this method. i am only watering 1 32oz cup every morning (night in the plant time). basically at the end of the day before the lights go off. so, i know where the extra humidity is coming from, so i know how to counter it. i have a fan in the tent, so when the lights are off there is air movement. and when the lights are on i open the tent up from the front and the back and have all the air from the room flow around. i have a portable a/c in that room, room is sealed up about 90% the temp never goes above 79 (lights off) and when the lights are on it gets to 77. yes, the temp goes down!! i turn the exhaust on when the lights are on. and only when the lights are on. if i don't it makes the tent shrink inwards and it fucks up the frame. i should have got the GRO TENT, Instead i bought the Sun Hut XL. but the SHXL was a tad bit bigger and a tad bit cheaper. so yeah, no exhaust during lights out. i heard watering at night is the best time, so that is why i water at the end of the day, before the lights go out.
thanks for the response!!
