Hey all! Can someone with experience running a sterile system (hydroponics) using H202 please advise me how soon I can start dosing H202? Can it be used from day one (post germination) or do I need to wait for the plants to reach a certain point in their growth? Yes, I know bennies or pool shock are both great alternatives to H202 but I already have a jug of medical grade H202 on hand so I plan to use it for this run.
