Re-using Coco?

[Deezy]

Hi all,
Whats the opinion on reusing coco for 2nd and 3rd grows?

From what i've read some say its better!
Some say it causes issues?

I had an initial fungus gnat problem which seems to have gone now, they never bother me too much and seem to strike no matter what i do, even though its indoors and I sterilised everything!! I think its the CannaCoco to be honest...

should I flush the pre-used coco before re-using? Leave it as it is or just chuck away and start fresh?

thanks all,
Deezy

hey Deezy I reuse my coco all the time and yes I pre rinse it to remove any left over nutes. I only use new when Im transplanting seedlings or clones into it for the first time. when I'm transplanting into the final 5 gallon pot its into the recycled they go. My thoughts are that its a grow medium,it does not contain any nutrients at all so why not reuse it

Yeh that makes total sense... so just fill a bucket with the coco leave it in PH'd + calmagic water over night then drain it off and go again? Will that work? Just store it in a sealed trash can?

I'm with oldjarhead, I re-use my coco on a rolling basis, mixing recycled coir/perlite into fresh coir mix. The only rinsing I do is the flush week I do at the end of each plant's lifecycle. I sift out old root matter by hand and use cannazym which supposedly helps the breakdown of old plant matter.

I was gana say the exact same thing except I dnt have cannazym

cannazym???? is this part of the canna line, has it worked to help break down the root system. I still find root balls from 2 years ago in the compost pile ,I stopped putting them in the compost cause they just don't break down have to try it thanks Beach

Hey Jarhead, yeah part of the Canna line. It's an enzyme product specifically for breaking down dead root matter and turning into sugars and micro nutrients. It also purportedly avoids the development of root rot and mold that could develop on dead root matter.

Does it do what it says on the box? I've never done a side by side so it's hard for me to say. I can say I've never had any root zone issues in the 2+ years I've been using it.
