First Grow: Barney's Purple Punch Auto

I'm going to be traveling for about 10 days over the holidays, but I didn't want to wait to plant seeds from Seed City by Barney's Farm. I didn't get original packaging, so nothing to see there. I accidentally made some pretty great soil in an outdoor garden box long before I began enjoying cannabis let alone growing it. I filled some 7 gallon cloth pots in August and some random wildflower seeds that never sprouted in the garden box began to grow. At that point, I knew cannabis would be next. I grew sunflowers to about 36" and I think there's a lot of similarities to cannabis. Anyway, I cleaned out everything from my tent on Wednesday, 11.20 due to lack of room and whiteflies. I scrubbed the tent and mixed in a fresh bag of organic potting soil into my 3 now empty cloth pots. On a whim, I dropped a Purple Punch Auto into the center of one about 3/4 an inch in and covered her up. I proceeded to get legitimately sick (strep maybe), and I found a lovely present Sunday (11.24) morning. I'd kept the area damp with a spray bottle and a plastic dome for some humidity. The seedling outgrew the dome in about 3-4 days (no pics). After day 1, just spritzed the little guy once or twice a day - very unscientific. Plan for the grow is to let it grow. I've never grown a cannabis plant, so i kind of want to get a feel for it. I'm expecting my travels to stress the plant but I've ordered some terra cotta plant feeders to hopefully prevent the plants from getting too dry. I know however many days they don't get fresh water and nutrients will affect yield, but I wanted to get it started. The other 3 pots will be getting fresh Purple Punch seeds after I get back Jan 1st-ish.
