My very first official grow!

Day 8 - things progressing as per the plan! But what do I know... this is my first grow lol Day 9 - seed coat still attached to one seedling. I'll put on the magnification glasses and see if I can resolve this. One dome off and one still on at this point. Seed coat coming off by itself. YAY. Changed light schedule from 20/4 to 18/6. Lights 30" above the babies. Day 10 - finally found the info i was searching for relating to my little germinated seeds. I know now that the lights I bought should be 18" above the tallest plant, set them for 25% intensity, and put them on a 18/6 schedule! So that's what I did... Day 12 - moved 2 of 6 babies into their 5 gal pots because of root growth in the dome. Will prob transplant 2 more tomorrow - I will check for roots coming out of the Rapid Rooter plugs. The remaining 2 are still kinda tiny and may be the runts of the litter. They look good tho... Rookie mistake - i brought in the soil from the garage which is colder. I did not let it come up to room temp. Installed the plugs with the substrate temp being 62. The warming mats are now on and bringing the temp up to 70. Going on the list of things to do better next time... Rookie mistake - another note to remind me that it might be better to plant the germinated seeds into the plugs while they are already in the soil? We will see how it goes and decide later. So i need to germinate in the rapid rooter plugs and NOT germinate them in paper towels and then move the seedlings, already germinated, into the plugs. Day 14 - have 2 tall, 2 medium, and 2 short little seedlings now growing in their 5 gallon pots. I think the difference was because of my germinating in paper towels and then over watering the plugs. My first grow so I'm not beating myself up at all. They all look fairly good. My understanding is that auto-flowers start their rapid growth around 20 days...
