Look for coco coir (fibre de coco). I live in a large agricultural area. I buy it from the big agriculture/veterinary stores, I pay around 6$ for a 5kg block.
The other really good thing to look for here is rice hulls (grana de arroz). Its a great perlite substitute! It comes from a industrial waste stream instead of a mine, it's biodegradable, and it's high in silica. What more could you ask for really?
A lot of sugar is produced in my area, so they are practically giving molasses (mollasse) away. It's so cheap they spray it on dirt roads to keep the dust down during the dry season. I bought a gallon jug for 1.50 and later learned that I could have brought my own jug and saved a dollar!
Some other things I've been able to source locally... English (Spanish)
Horse manure (caca de caballo)
Cow manure (caca de vaca)
Chicken manure (caca de pollo)
Sheep manure (caca de oveja)
Goat manure (caca de cabra)
Cricket frass (caca de grillos)
River sand (arena de rio)
Agricultural lime (cal agrícola)
Good luck, if you need any help let me know!
