Here's what we can help with:
- Dosage: hard to pin down exactly. Every cactus is a natural product with varying concentrations. Start low.
- Soil: use a well-draining cactus mix. You can find ready-made options at garden centres, or mix your own with sand, perlite, and regular potting soil.
- Black or brown spots: usually harmless fungal spots. They dry out on their own.
- Strongest variety: Peyote (Lophophora Williamsii) is the most potent, but grows very slowly. For a faster-growing option, try the Bolivian Torch.
Anything else? Just ask.
