Does anyone recall the name of the product that was discussed a few weeks ago which facilitated the breakdown of algae and fungi when added to irrigation water? I think it started with an H. Someone asked if it caused the potting moss to break down faster, and someone else said no, it didn't. Thanks!
PS Not Physan or other fungicide...it was something that speeded up decay.

Hygrozyme... or Orchid Champion from Sipco are the same thing. (http://www.sipcobio.com). Slippertalk just had a thread about this referencing your very question.

Thanks very much Tony, that was fast! Were people happy with it?

Hard to say... I tried it last spring. I gave it a good try, but it is expensive and I found other tweaks provided more immediate and discernible benefits. But my evaluation was hardly scientific.

I don't know others reaction to using it.

What other tweaks did you do, Tony?

My interest is in keeping down the cyanobacteria mats that are piling up on my sphagnum moss, especially on plants that are mounted. I bet this will eliminate that build-up of goo. I've noticed that my plants make a burst of growth when first mounted, and then slow down, more or less when the medium starts to get full of junk. Not sure if this is cause-effect or just correlation, but I want to experiment with this.

Well...

Last spring I starting using Orchiata in earnest. I also started a few plants in straight sphagnum in baskets and got good results and used Peat Lite (close to MSU) at 100-125 ppm N every 3 out of 4 weeks.

Recently (Early December 2011) after flushing the K (Potassium) out of my pots for a couple of weeks, I started using a fert lower in K (as in NPK) (See the multiple K lite threads on Slippertalk) , and started to add farfard type potting soil to my orchiata at 10%. I have been potting plants in 40% Orchiata, 40% similar sized perlite, 10% charcoal and 10% farfad. My GH faces SE and gets no direct light after 2 pm at this time of year, yet I am see more growth over the winter than I have seen in the past few years.

Give me another year or two to see if I stand by these statements. :) :) :)

Lou, have you tried something like Zerotol? http://www.biosafesystems.com/Product-HORT-ZeroTol.asp It is just concentrated H2O2.

Tony, won't H2O2 damage the roots over time?

Not at the effective %, I am thinking close to 3%. I have been using it for a few months, no damage to the roots or plants. It does kill algae though. It takes a few applications, but it will kill the algae.

Do you mean that you water with 3% H2O2, or do you dilute it in your irrigation water? If so, what dilution do you use, and how often do you use it? I could try that, but I am guessing the enzymes in "Orchid Champion" might do better.

Tony, what are your temps like this winter compared to previous years?

I keep things above 63 at night in the winter. Daytimes temps go up a few degrees to 10 degrees during sunny days. I have a tough time in Nov/early Dec - cool enough so the vent does not open, yet warm enough so the heater does not kick on - so it gets a little stagnant. I was a little preoccupied this year so I was not on top of this as I should have been. My greenhouse is pretty small, it is a little tougher to manage than larger ones.

Lou, I am thinking it is about 3% in the diluted form? What I understand peroxide does not damage plants/roots at these low concentrations. I have applied it liberally to the greenhouse walls and plants about 5-6 times (two RTS bottles) - every other week since mid December when I was trying to overcome a general funk in the GH. After a couple applications, most of the algae growing on the glass was dead. First Rays is now carrying a RTU (Ready to use) spray version - Oxidate.

Thanks Tony. Unfortunately H2O2 is a semi-controlled substance here, impossible to get in large quantities because it is used in the processing of cocaine.
