Second attemp, first grow ever

So, on the 4th day of my first attemp it went south! My seedling died to my error. I fought hard with humidity in my small tent as I believed it was a must to have 70-80 % as most googling telled me this during the early stages. I may also have overwatered slightly. It was later shown this was not the problem. My errors would kill the poor one. I then thought the seedling had gotten mold as a result humidity/watering problems, asked for help on another forum and got some vague and inexperienced answers had me panicking a bit! So I just removed the seedling and the top soil and popped another seed in a glass of water. Way too late I got the real answers I should have waited for, it was normal, just the white fuzz on the stem the seedling use for nutriets and protection or something like that. Normal in any case. Well, already too late as I mentioned. After all this I dropped the second seed in a glass of water at around 2 pm(4th Sep) September 11th ca 2 am and the new seed is showing its tap root. In she goes! This time I will settle with those 45-50% and just relax and see it as an experiment instead I misted the soil and used a bottle dome that I had poked holes in the top for air to get in. Hope someone may learn from my mistakes in the future. September 14th ca 2 am and my second girl popped out of the soil. Marvelous little wonder
