Mold on Rapid Rooters
I've got nine, 3 week old plants (tomatoes, habaneros, and beans) in an ebb- and- grow system in a 4x4x6.5 greenhouse. I started them in rapid rooter plugs and then transplanted the plugs into net pot bucket lids with water- wicking rocks as growing medium. There is ample airflow, and the humidity stays around 50%
I have now noticed some gray and light green mold on the rapid rooters, especially affecting the tomato plants. (They seem to be dying.) I have heard that adding 3% hydrogen peroxide to the reservoir should help kill the mold, but I want to be sure it wont harm the plants, and if not, how much should I use??
Any other troubleshooting suggestions are welcome as well.
