First Grow 00 Seeds Northern Lights

I am excited to start my first grow and to track my progress here! Being my first grow I am bound to make many mistakes so any advice or guidance will be much appreciated. Seeds were planted Dec-18 and the first signs of life showed on Dec-23. I have been keeping watering to small doses depending on the dryness of the soil. Speaking of soil I am using Fox Farms Ocean Forest and will use the FF Trio when it comes time to feed the girls. Day 7 brings the end of The first week of these plants lives. It also brings some realization that I need to find a fix for the low humidity, I am looking into humidifiers. Besides the humidity issue I have also purchased a small inline fan with some ducting to help ventilate the tent. Another small item I am planning to purchase is a small clip fan that will replace the desk fan currently in place. I chose the Northern Lights strain based on many reviews advocating it as an excellent beginner strain.
