I just ordered a quart of Hydroguard and am thinking of adding some to the reservoir to prevent root rot. My temps run between 72 F & 84 F (inside of the unit - not sure about water temp) so I figured I be proactive. I’ll be on Day 5 of germination when the Hydroguard arrives in the mail tomorrow.
Should I go ahead and add the Hydroguard to the reservoir right away? Or should I wait til my next drain/fill cycle?
