Big Devil Auto

Seeds were planted in soil Thursday night and have been at about 50-60% humidity and between 70-80 degrees Fahrenheit. They are in a custom bureau gutted by myself and the actual grow area possible from the top of the pots to the top of the bureau is 2x2x3. I have this full wrapped with aluminum foil tape and have covered an holes. Also have a 4” desk fan with another on the water vented with a fiberglass air filter that will serve as my intake and I have a 4” inducter with 80CFM that I’ve been using as my intake. In the pots themselves are 100% Vermont grown organic compost soil. Bought at my local gardening shop. I have been lowering PH from about 7.5 down to 6.5 with just Tap water and will switch over to distilled once the plant can take nutrients. No sprouts yet, not sure how long this process normally takes as I planted the seeds directly in the medium? I have done the paper towel method before and that has taken 2-3 days for them to germinate. I also currently just have a cheapo 19W Feit light bar hanging about a foot above the soil. Doesn’t seem to be getting too warm underneath it and I’m using a meter to check light at the soil and it reads right in the middle. This is my first grow so any tips are greatly appreciated as I’m doing a micro grow with autos and am looking to increase my yields as much as possible. Thanks!!!
