The Sinclair Horticultural Perlite is designed for gardeners and plant enthusiasts seeking to improve soil structure and plant health. Its primary benefit is enhancing soil aeration, drainage, and water retention, leading to stronger root development and healthier plants. A potential caveat is that its lightweight nature can cause it to float to the surface when overwatered. This 100L bag of medium-sized perlite (2mm - 5mm) is a natural, sterile, and pH-neutral volcanic mineral that has been expanded by heat. It effectively prevents soil compaction, insulates roots from temperature extremes, and is suitable for seed starting, potting mixes, hydroponics, and as a soil amendment.

Sinclair Horticultural Perlite is made from a naturally occurring volcanic mineral called perlite, which is expanded by heating it to high temperatures.
Horticultural grade means the perlite has been processed and sized specifically for use in gardening and horticulture, offering optimal aeration and drainage properties for plant growth.
Yes, this perlite is excellent for seed starting. Mixing it with seed-starting mix improves aeration and drainage, creating an ideal environment for germination and early root development.
A common ratio is 1 part perlite to 2 or 3 parts potting soil. The exact amount depends on the plant's needs; plants that prefer drier conditions benefit from a higher perlite ratio.
Yes, perlite is a natural mineral and is considered safe for use in organic gardening practices as it is inert and does not add chemicals to the soil.
No, perlite is inert and does not contain or add nutrients to the soil. Its primary function is to improve soil structure, aeration, and drainage.
Store unused perlite in a dry, cool place, preferably in its original packaging or a sealed container, to keep it free from moisture and contaminants.
This is a natural characteristic of perlite. Ensure proper drainage by using pots with drainage holes. Avoid overwatering; allow the soil surface to dry slightly between waterings. If it becomes a significant issue, consider mixing the perlite more thoroughly into the soil or using a finer grade if available for other applications.
Wear a dust mask and gloves when handling dry perlite, especially when mixing large quantities. Work in a well-ventilated area. Lightly misting the perlite before mixing can help reduce dust.
Adjust the ratio of perlite to soil. If the mix is too airy, reduce the amount of perlite and increase the amount of compost or potting soil. Ensure thorough mixing so the perlite is evenly distributed.
Wind can easily move lightweight perlite. If used as a top dressing, consider using a slightly heavier mulch or ensuring containers are placed in sheltered locations. Mixing it lightly into the top layer of soil can also help keep it in place.
Setup: No setup is required for Sinclair Horticultural Perlite. It is ready to be mixed with soil or used as a standalone medium. When mixing with soil, aim for a ratio that suits your plant's needs; a common starting point is 1 part perlite to 2 or 3 parts potting soil.
Compatibility: This perlite is compatible with all standard potting soils, composts, coco coir, and other growing mediums. It is safe to use with all types of plants, including vegetables, herbs, flowers, houseplants, and trees. It is also suitable for use in both containers and in-ground gardens.
Care: Perlite itself does not require care. However, when used in potting mixes, monitor soil moisture closely. Due to its porous nature, it helps retain water, so adjust watering schedules accordingly to prevent overwatering. Store unused perlite in a dry place, preferably in its original bag or a sealed container, to prevent moisture absorption and contamination.
