Sativa-dominant auto's

My grow light finally arrived, and I didn't realize that the standard hanging equipment made it hang so low, so it is currently only about 12 inches or less from the tops of all the plants, which is probably too close. Going to tinker with it when I get the chance to find out if I can drill some new holes in the ceiling, relocate the mounts, and raise it higher. They're on a light schedule now of 18 hours on, 6 hours off. I was sick all weekend and also hurt my back badly, so lately unfortunately I haven't had the chance to give these plants the daily care they've needed. Have to say there has been some noticeable growth between last week and this week, so even though these plants are tiny they are still progressing. The amnesia haze grew from being 5 inches to 6 inches. I ordered 2-gallon fabric pots to be used INSTEAD of these 5-gallon pots, considering how damn small these plants are. When they arrive I might try transplanting them.
