reusing perlite

[El_Badass]

I have perlite left over from my very first grow. and I really want to reuse the grow media. I've done some googling and all I got was that it's a good idea to sift and to use waterd down peroxide to sterilise. I'm not sure if reusing is something that's widely done by other members here but if anyone can shed some light on this for me it would be greatly appreciated.

[loylty gets u nothing]

im sure there is a thread pinned evn on cleaning and reusing coco,perlite,geolite etc

havent got a link cause im computer dumb

but do a quick search on site

i think it was done by eikiel maybe

all the best

personally i prefer to use fresh medium every grow

Thts right Billo .. I thought it was Eikels thread too .. But was Hanky ..

Here's the Link

 

Doesn't say too much about cleaning it , I would presume just rinsing with clean water would be fine .. But there would still be some salts buildup ..

 

But I'm with Billo , fresh medium is the way to go if you can ... Perlite isn't really very expensive ..

And the old medium needn't be wasted .. An outdoor garden loves perlite mixed in with the soil Improves the soil permanantly ..

 

Not too sure on sterilization .. I know garden soil can be sterilized in a microwave () .. not sure about perlite tho

(DOn't blame me if ya do it and blow up your kitchen) heheh

 

I'll be interested to see what other ideas there are ..

I've reused the same perlite for 3 grows so far with no adverse effects

just gave it a good rinse and mixed it around and got out most of the old roots

If you add vermiculite you will need to mix it well because it tends to sink to the bottom

 

Stay cool

if you use a coliseum you've no choice. mine's been running for 3 years now without change. you'll never get all the old root out so use SensiZym or CannaZym to dissolve them into something the plant can use or it may just rot into something lethal to the plants. you can disinfect with H2O2 if you want but i use mycorrhizal fungi so i don't do that and the medium stays sweet and productive.

i rinse for the last 2 weeks of flowering anyway so nutrient buildup isn't an issue.

thanks for the input guys. I wondered about using domestos to sterilize but there's a big difference between using it to serilise an old fish tank and a growing medium.
