Some of it is potential aquarium/microorganism feed (I'm growing an algae stock for tardigrades...which are neat!) feed. Some is ""edible/nutritious"" (spirulina).
They're experiments that are confined to 1 gallon jugs/jars each. I enjoy it. If other people don't care or think it's silly... they're welcome to think so. To each his own.
