Is it possible to oven bake coco with perlite in it to sterilize? I have pots that have more roots then medium. I just harvested and would love to reuse this stuff. Only used it for one grow. Also I have heard there is a controversy over this method. I know all about beneficial bacteria being killed by doing it this way, I don't care. I have most of the roots out, I just want the remaining roots some how killed and destroyed and out of the coco as much as possible and I want this stuff sterilized and ready as easy as possible. It seems that the oven method is best. Please someone confirm this. Finally what is the best oven method to use?

I have heard of so many oven methods I'm scared to dedicate to myself to wasting time trying them all. Any one aware of the best method out there?

Look in the organic section.

There is something called no-till organics, where people cut the stalk of a finished plant then plant a new plant right next to the old stalk.

Look it up, it might suit your fancy

Put it in a pressure cooker

or a microwave slightly moist for a good while

But why reuse, it will cost you more in electric than buying new

I have done this once many years ago, I promiser you
...you will regret this ...lol
the stink will blow your mind

and if you do it inside the house will never be the same again
for you there is a chem called callazine?? or similar for removing roots to decompose them quick,

but you need not worry, see the roots for what they are
little cookies of nute for you plants to much on while waiting for you to feed them ..lol
as you said above, they were rootbound consider a larger pot and work it so you get
1 gallon of space in the pot for each month the plant is with you or 1 liter per week

boiling water should do it. will really fuk those remnant roots up.don't know how long you have time wise but for future re-dux you could try spreading old soil out and cover with thick black plastic. it cooks from sun, blocks light, and starves from oxygen.couple of weeks should do it.i like the boiling water idea tho.depending on amount that needs to be sterilized.do several pours.

I've used the same coco for 5 years
This is what I do:
I use cannazym regularly and double it during the last watering.
After the plants are harvested the coco sits for a month or more with the rootball intact in the pot. All of the small roots decompose and I am left with a stem and a small root ball which is easily pulled out.
The pot is emptied over a 3/8 inch screen to separate the larger roots still in the coco. The remaining mix is then poured over a smaller screen (actually a window screen) to remove the "fines".
It can then be rinsed if you want. You can rinse it with tap water but you will have to replace the calmag and enzymes. I usually don't rinse because then I have to dry before I store it and it is not necessary if you can manage your nutrient levels.
I still have to buy a bag or two every so often to replenish
I have never thrown away coco except for what I sift out. Coco costs me almost $40 a bag. I don't really want to buy it every 3 months. Doesn't look good to the neighbors either to have all those bags delivered to my house on a regular basis. just another opinion;-)
