how to sterilize properly after Pythium Wilt

Hello everyone,

I recently lost a plant due to Pythium Wilt. It was in a GH Waterfarm drip system with clay pebbles.

From what I read around the nets those Pythium spores seem to be extremely tough bastards. I'll be building a new grow room soon and don't want to infect it... so what is the best way to sterilize my equipment? Would any of the following help

* boil the pebbles
* soak them with isopropyl alcohol and set them on fire
* put the bucket and tubing in the dishwasher

Or is it best to buy new pebbles? Or just buy a whole new system? Obviously I want to save money, but more importantly I want to make sure no more plants die.

Thanks in advance!

Soak them in bleach and hot water for a long time.......

i soaked mine in bleach twice over night, its coming back, i would suggest a h202 mix

Try soaking it in a fungicide. After the hurricanes down here 5 years ago.... Pythium was rampant. It took 2 years and many cross fungicides to get rid of "most" of it.

One of the very best fungicides for Pythium is called SUBDUE MAXX. It isn't cheap, but it is effective.

I also cross fungicide my soils with AGRI-FOS. It usually takes two different fungi's used in tandem to defeat Pythium.

Ummm buy new ones
