perlite alternatives


Recommended Posts

what can I use instead of that blasted white rubbish? I hate perlite, it gets everywhere washes out of substrates after a while and is a general pain in the posterior to use :ireful2:

Horticultural charcoal ? I'm going to try some of this stuff on a few test plants. Has anyone else tried this ?

 

I've added charcoal to Cephalotus mixes in the past - though I have no experience with that particular brand. Coincidentally, I ordered some orchid mix from them a couple of days ago. I see that they use rice husks as an alternative to perlite in some of their mixes.

You've just jogged my memory ! I've recognised the seller now and i ordered a small bag of their Nepenthes mix to test last year, and 3 of my Neps are sitting in it doing great. It contains cocopeat, coconut husk charcoal, and rice husks, but i added my own sphagnum into it as i found it a little on the fine side by itself due to the rice husks. I already buy individual supplies of sphagnum, orchid bark, and perlite for making my own mixes, so i think i'm definately going to drop the perlite in favour of charcoal from now on. No more breathing perlite dust for me :smile:

So yeah Sam, i'd recommend it.

I have also added charcoal to Ceph mixes in the past as they are naturally exposed to periodic burning of overhead shrubs and lower vegetation such as sedges. I suspect that it naturally forms part of the soil that they grow in.

Just make sure it's the horticultural grade stuff not the quick lighting stuff soaked in paraffin. CPs wouldn't like that at all. I'm now going to seek out bulkier bags of hort charcoal as I had bought small boxes before and there must be a seller out there on the interweb!

That's the same product I was looking at on Amazon and similar prices too. I am guessing that will be a 20-40 litre sack (having googled the density at 240-480kg/m3).

Is there any risk of salt in coco-based charcoal as has been mentioned with the coir threads before?

Cheers,

Steve

Aparently not. This blurb is taken from their Nep mix......

"Our cocopeat has been matured for two years before processing. The first step is to remove excess fibres and then to wash it with FRESH WATER to reduce salt levels to below commercially accepted levels. Ours has an EC of <0.5 mS/cm which will stand any professional scrutiny. pH range is 5.8 to 6.5."
