Questions about flushing before harvest

Hello @dbrn32, @latewood, @Myfriendis410, This is my first grow and I’m preparing for harvest. Growing in RDWC system in a tent. When flushing, do I add Florakleen and/or Hydroguard to the water? How long should I flush? Any other tips? Many thanks!

Tagging some others for advise…

I run R/O with Florakleen and monitor the TDS of the solution. Change daily (if TDS climbs) and I ran 4 or 5 days. My TDS at harvest was around 100 ppm.


Can’t be of much help, I don’t grow hydroponics or use any of those product. Sorry!
