Morning Surprise

10/20 - struggling to keep humidity up for the seedlings. During light hours I'm running the light at 28"/50%, exhaust fan on low, circulating floor fan on medium and the humidifier on max. Going through a gallon of water in the humidifier and this isn't sustainable. Kept the DG & CDLC under a dome, but read that once in the seedling stage, the dome should be removed. So pulled the dome off these two and left it on the AA - still hoping it will pop. Read that a bucket with a rag (to wick?), in front of a fan, will help.

Decided to turn the exhaust fan off and see what the temperatures do. Prior to turning the exhaust fan off, the tent maintained 75F and about 54% RH. With the exhaust fan off, the temperatures went to 79F but the RH also increased to 75%.

10/21 - checked on the seedlings this morning and was pleasantly surprised to see that the AA seed had popped - all three are on their journey now. Very relieved to see the last seed pop. Tent environment looked great 78F and 73%RH, with the humidifier reservoir only down a bout 1/4. Pink milk crate is DG, green is CDLC and blue is AA.

Question - do you use a VPD chart at this stage? Can't really get a leaf temp. Thanks and advice/comments are welcomed!
