Doing RDWC for a couple of years now, always using tea and last 4-5 grows always got a nasty root rot mid flower and lost most of my crop.
So I decided to go with sterile, using pool shock and ORP controller (ORP basically says, mow much free chlorine you have in your solution).
My findings so far:
- It works, mid flower now, all looks fine (except som K def)
- Some people say, 1ppm wont hurt your plants...NOPE, 1ppm constantly will kill them, that is around 750mV at ph6, which killed all my seedlings in a day.
-So far it seems, that good ORP level is around 420mV (less than 0,1ppm) runing constantly
- everything above 500mV resulted in stunted growth
Dosing basically looks like this:
I have a 20l tank with pool shock solution and orp controllers, that open washing machine valves, when Orp level falls below preset value.
Just a question, if somebody can help me: I developed misterious K deficency. Does anybody knows, if it can be related to Chlorine somehow? If not, must be VPD, as it is hot and AC lowers RH to 40% at 29-30C
Any questions, just ask...
Thank you!
