Day 16 (3/21): No pictures today unless someone wants to see something specific. I made a co2 bottle thing with some yeast, sugar, and water. Maybe that will help fix my problem. I also gave all of them about quarter strength of some grow big. I know they are young, but I am out of ideas why they are not surviving. I also transplanted the biggest rhino it in a 2 liter pop bottle. Hopefully it takes a liking to that more then the solo cups. Plants are going to be left a couple days without watering, so that is why I watered so close in cycle. But they were all dry. I doubt they will last while I am gone.
