Ya I'm not hydro too. That's why I can only remember bits and pieces.I don’t m ow much about hydro but z7 or hydrogaurd is a must from my understanding!
70-72’F is optimal for Oxygen rich water but also right on the boarder of bacterial growth and fungus. Using an enzyme cleaner like z7 or hydrogaurd will help stabilize and maintain a healthy root zone in the hydro pots!
If I’m wrong I hope a hydro guy will yell at me lol! But from my understanding this is accurate! Lol
