are you saying that general organic potting mix is no good to sprout chillies in? i just bought some general veggie and plant potting mix from bunnings.
Unfortunately most of the commercial stuff in Australia is crap. Some of Debco's products are probably the better of the lot if you can find them (and surprise, surprise... Bunnings no longer stock any of it).
It seems like Bunnings are only sourcing the cheapest of the cheap now (at least that's how it looks). The cheaper they can get the product, the bigger the markup they can put on it? Just a theory.
You use jiffy pellets right (or fothergills versions)?
Why not reuse the netting from them?
If I was using jiffies I'd be saving the netting for seed isolation and anti fruit fly netting.
That's an idea but probably too small I reckon. The thing with fruit fly exclusion is you don't want any fruit touching the sides of the bag. Apparently grubby fruit fly will still get their stingers in.
Mum went and bought me a few metres of tulle netting today anyway. Bless her heart.
