First Timer Indoor Auto Grow

To start, I just want to say I've been planning this grow for a while and am super excited that they have been sprouting recently. 3 have popped out of the soil, but one Tyrone special is still making it's way up. I planted them almost a week ago after leaving them in a glass of water for almost 24 hours. I live in Maine, so it is legal to have these plants in the house. I'm using the only applicable space in the house, which my dad thought was best (he's been growing for years). It's pretty much a 2 1/2 foot wide, with more length and height than I need, so I closed it off using reflective styrofoam squares to make for a smaller, more efficient grow space. I usually have all walls enclosed, but for the pictures sake I took down one of my walls that I made to be moveable so I can access my plants. I put more styrofoam under the buckets to move them to be 24" away from the lights. I'm using two mars 300 lights, which with the reflectivity should definitely be enough for 4. I use organic soil, and when they're ready I'll be adding the Flora Trio nutes. I PH my water to 6.5, but I have not tested the runoff water. I think while they were germinating and sprouting I may have overwatered a bit, causing the leaves to curl down, but other than that I think they are going perfectly. Oh, also since it is pretty much still winter here and we're running the wood stove, the air is definitely dry. I'm not sure the exact percent, but I know it's not nearly as high as it should be. I soon will buy a hygrometer (or whatever it is that measures humidity) as well as a mini personal humidifier in hopes to better the situation. I also plan to use LST, but I'm not sure to how many of the four (I think it'd be interesting to compare a plant with LST, to one without). I'm afraid I may have forgotten something, if so I will add it later. So overall, any thoughts? Since this is my first time ever growing, I would love to hear any advice/criticisms that you may have. Thank you for reading! Cheers to a successful grow! 3/30 Update: After seeing my plants for the first time today (those pictures are from yesterday), they've basically doubled in size in less than 16 hours! A Tyrone and the blueberry are about 2 inches tall, and the chemdogging is following close behind. My other Tyrone has begun to sprout, but no sign of leaves yet. I think tomorrow will be day one! I've decided to try running the lights 24 hours a day just as they seem to be gaining a lot of size right now, even with the 20 hour light schedule. 4/2 Update: My second Tyrone is up and growing! I was a little worried that it wouldn't sprout correctly, as at one point I found the seed and the roots (at the time they were very small) completely above the soil, so I re buried it. Luckily it has sprouted and is chugging along with the rest of them, 3 days younger. All plants look very healthy with no signs of deficiencies or stress.
