I have a blue dream that is about 3 weeks from harvest and she developed a pythium infection. I can already see the plant begin to eat itself as its nutrient uptake from the root zone diminishes. I know how I caught the stuff. It’s going to require a full operational reset on my 2 booth perpetual grow setup. I just want to limp this gal over the finish line if possible. Because if not, I’m gonna be boned for like 4 months. I’m running hydroponic DWC single buckets per plant, with independent chillers on each. Water temps are 68° but the pythium still showed up. I’ve been using hydro guard per suggested ratios every week of its flowering cycle. Im feeding advanced nutrients sensi-grow/bloom at their master level nutrient recipe. The plant is about 15 weeks from seed.
I’m thankful for any and all input.
Did you try going sterile?
Swap out your nutrient rez for a mild peroxide/water solution or use something like Florakleen and run for several hours, then drain and refill rez with nutes. That’s about all you can do at this point.
I don’t understand what you are asking me.
Thank you. H2O2 is accessible nearby. Anything else requires a couple hrs to town and back. Any ideas as to nominal ratio? And define “several hours” for me, please
Make it ata 40:1 ratio and run for 12 hours as an example
Peroxide will break down quickly so there’s not much benefit to running for more than a couple of hours, unless you replenish the peroxide as it gasses off. I would run something like 1 cup per gallon of 3% for four hours max. You also, unless water becomes turbid, can simply mix fresh nutes into that same solution as the peroxide will be gone. If you have access to R/O I would definitely use that.
If you have any really nasty bits of root you can also carefully clip that out and discard.
Thank you, immensely.
I will be trying that later today.
Peroxide would be running sterile res. It’s just not the only way to do it.
I use uc roots in my cloners is this something that could be benificial in a dwc or rdwc setup? @HappyHydroGrower runs great hydro grows with awsome results and has probably experienced this.
