WHY LUPIN OVER SOY
Built for mushrooms. Not for horses.
Soy hull pellets are manufactured as horse feed. The binding process uses oil as a binder – great for animals, but not what your substrate needs. Our Lupin Hull Pellets are different from the ground up.
We use steam to bind lupin hulls into pellet form with zero oil. After pressing, they go through a dehydrator to remove all residual moisture — a clean, dry, purpose-built substrate supplement with no added oils and no additives.

HOW TO PREPARE
Masters Mix preparation guide (3kg block)
- 1Weigh out 525g hardwood sawdust pellets and 525g Lupin Hull Pellets into a large mixing container.
- 2Add approximately 2 litres of water and mix thoroughly until combined. Boiling water speeds this up significantly.
- 3Allow to sit for 30–60 minutes so pellets fully absorb and break down evenly.
- 4Check field capacity — squeeze a firm handful and only 1–2 drops should come out. Not a stream, not bone dry.
- 5Pack into an autoclavable mushroom grow bag. This ratio yields approximately a 3kg block.
- 6Pressure sterilise at 15 PSI for 2.5 hours.
- 7Cool completely before inoculating.
If substituting hardwood pellets with raw sawdust, water requirements will differ. Start with less water and adjust to reach field capacity. The 2 litre figure is a starting point for pellets only.Adjust the ratio according to the amount of bags you want to produce.
SPECIES GUIDE
Which species grow best in Rootlab's Lupin Hulls Masters Mix?
These four species prefer a leaner substrate and don't perform as well with heavy supplementation. This applies equally to soy and lupin hull Masters Mix.
