Can also look at the hydroponics shop for some plant food and microkill. Emergency Treatment: top 1. Hydrogen Peroxide root dunk -Remove each plant from system, snip off diseased roots. -Dip/swish each plant and container into a strong H2O2 solution, until diseased roots have been removed. Repeat as required. 2. Sterilize equipment All equipment should be disinfected (including hoses and pots, etc) with bleach solution or 10% h2o2 solution before plants are reintroduced into the system. Rinse well. 3. Add root rot medication. Add anti-pythium additives, Vitamin B1, and fresh nutrients to a sterilized reservoir at a lower strength, at cooler temps. Reduce light levels. After a week or so, after new roots appear, add some root boost additives. (taken from: https://tokecity.com/forums/showthread.php4?p=2598)

A spore print is like the reproductive bits of a mushroom. It is commonly used to identify the type of mushrooms or to grow new mushrooms. Don't eat them. Look at them under a microscope, study them, trade them or if you're clever (and it's not illegal) grow them.
