Clorox bleach, regular, no additives, not the no-spill kind. So yeah, these are new plants with new roots that are just poking out of the rooter plug and descending toward the water line, approx 1-2 inches below. They look great, amazing. Then they just stop right before the water surface like...

So no more sterile for you? Can I ask why? I could use a reason to bail on it.

Did you ever test to see what your ppm was? Were you growing from seed and your youngish roots hit the water no problem?

With a standard pool kit. It's a visual test so there is some room for error but not much. My tap water measured less than 0.5ppm but you can see that there was some reaction from the test. Whereas my RODI water tested zero, no reaction whatsoever. A pool is like 3-4ppm chlorine. My cooler was...

Thanks for the answer. So help me understand something. If UC Roots is the same thing as diluted bleach/shock, what accounts for the difference in the rez? I'm diluting it almost to zero. It's baffling to me. If you were to chlorine test your rez after a UC Roots dose, would it read less than...

Yeah, for now I'm just running bennies instead. Just tough to believe that a tiny bit of sodium vs calcium makes all the difference. Just for my sanity, you run sterile the entire time? And your roots descend into the water no probem?

Def the bleach because like I said, I can redo the rez without beach and everything is fine. It could be the difference between bleach and shock but shock is tough to get and expensive nowadays. And Ive seen people saying they are doing sterile rez with bleach and they don't have this issue...

I can not get this to work for the life of me. I understand chlorine can be dicey on plants and I saw that people were saying cannabis can handle up to 4-5ppm chlorine just fine in a sterile rez. I tried 2-4ppms. No luck. The roots refused to submerge. This is from seed with a rapid rooter. So I...

You need to test their strengths before you start because they could be degraded. I just tested some brand new bleach and it was around half the strength on the label. I know a lot of sterile growers use powdered pool shock but I don't know if that degrades over time. Bleach definitely does. I...

My tap water tests very high (650-750 ppm) and I'm looking for a RODI that can handle a 17 gallon reservoir with that tap water to work with. Will cheap RO buddy cartridges be able to handle that? It's my first grow so I thought I would start small but what do you recommend?
