Understood and thank you for the info. It does seem the safest option after disinfection is just to simply toss everything and not try to take cuttings. I have already accepted every plant we have is a loss, but was going to try to preserve some of the genetics. Is probably just going to be a waste of time however and the logical decisive option seems to be destroy everything.

Another interesting article about high air flow activating plants SAR innoculated with fusarium, and inhibiting the fusarium colonies substantially

Just for clarification Chris what symptoms were your plants showing? Was it the wilt variety of fusarium, where when lights were on all the branches and leaves would fold down? Or the root variety where the plant was obviously unhealthy, but limped along.

Forgive me if memory is a little faint, as this was almost 15 years ago. It was root fursarium. Plant looked somewhat ok in veg, a little pale, small root mass, stunted growth. During flower, plant would just start to yellow, drop leaves, and slowly die. If you were able to finish, pathetic small buds, no flavor or smell. This was on a strain that you could pull at 7 weeks, large yielder, beautiful flowers. If it was something that went 10 weeks, you would never make it, it would be dead.
Yes I would cut my losses and start over.

Did you ever try sterilizing your cuttings Chris? I read articles where 14 ppm bleach killed 100% of fusarium spores in 6 mins. The lab tech I spoke to was very certain that fusarium root and crown rot should not be in the growing shoots as it's very site specific. He said any contamination would be carried over from airborne spores resting on surface of leaves. Being a long time ago I'm not sure if you remember sterilizing the cuttings to that extent but just curious?

No, never tried sterilizing, never knew it was an option at the time. Had already invested to much time in trying to recover (almost 2 years), so I just baled out . Sorry I can't help more.

Your a brave man. Good luck. Update this thread if you can, I'd be interested in hearing if it works for you.

Its considered standard procedure for alot of greenhouses, hard part is finding the right concentration that eliminates all surface pathogens but causes no phytotoxicity or delay in root initiation. I'm hoping 20 PPM is not too much, tested it on 50 cuttings and they still perky, its still too early to see if it affects root initiation however. Of course this is all pointless if this fusarium is a true systemic however. Will definitely update.

Spent all day repainting clone room with Zinsky's anti mold paint. As soon as ozone generator arrives going to run that all day. 10 G Per hour output, I read that 20 mg/l killed 99.9% of fusarium within 20 minutes. Unfortunately in a 10X10 room I think I will only get it up to 15 mg/l. Might run it for 24 hours, just in case going to spray entire room down with 200 PPM Bleach solution, and then heat room up to 150 F for a few hours. Adding a UV filter to RO unit, footbath with disinfectant in doorway, 6 inch HEPA filter constantly on, rapid rooters will have a massive amount of beneficial microbes innoculated, long story short if these root and test positive for fusarium again, the only source could be from the mothers and that it's truly systemic.
