Backyard Aquaponics
A place to discuss aquaponics

THat is why I ask... I was strongly advised against using coconut coir - the shop owner was concerened that it stays TOO wet for a continious flow system... and also enquired as to wether it would be PH balanced and be low in salt/s..., as that can be a problem!

Mmm...that makes it difficult.
I guess that shreaded cane would go mouldy.

I just dont want Jaymie to go purchase stuff which could be 'harmful' to here system!,...
THe store owner had not used the it in a system like this before, but advised that from his experience that it would NOT be his medium of choice - but then again the proof of the pudding is in the tasteing!

fair call AM.

I won't be eating the coconut fibre! have enough fibre in my diet already!
We have just been reading a bit on the coco coir, they reckon it will absorb 8-9 times its weight in water. On of the mobs that is ffloggging it on ebay is a hydropon. supplier.

that was part of the argument put across to me today - it stays VERY wet for a LONG time... roots could/would perhaps beging to rot! I add the stuff to my potting mix to help retain water for longer, so I understood what he was on about...

hmmmmmm, that is a very good point.

Ok so we pretty much say no to coco, do we go with gravel, or maybe perlite?. any advice?

okay, the hydro shop owner said try perlite way before coco... I have used gravel and it worked very well... and expanded clay balls would work well too (as well as be MUCH lighter than gravel!)

thanx! I owe you a beer!

Isn't muzza using it?

I'd say its fine for F&D as its always being "re-wet" by oxygenated water.

But you have a valid point for cont. flow

WooHoo

We need a report back from muzza then...

on a completely separate subject... its possible we might just get our first rain for the season sometime in the early morning (please Huey)

keeping my fingers crossed!
