Swiftair Perlite 100L Bag for Horticultural and Organic Gardening 2-5mm Perlite

This product is brilliant. Aeriates the soil, stores water, helps growth, great for the health of the soil. It has helped my allotment soil to breakdown the clumps and let it breath. Definitely worth it. Apply liberally mix in well.

This huge bag has lasted all year. It's been put in indoor planting, outdoor planting - can't believe how little goes a long way. And I can't believe the difference in price here compared to buying in local garden centres. It would cost £100 for the same amount if I bought it in the local shops in small bags. Repotting swiss cheese plants using a perlite and soil mix has improved their root drainage massively and makes shifting the plant around a lot easier as the container is now half the weight, as perlite is super light. Outdoor veg and flower troughs are now less hassle to move around too and the perlite means roots get a great chance to spread fast and drain easily - which is a bonus in windy, rainy Scotland. I've also been adding it to areas of soil the garden which house plants best grown in grit and they seem to be thriving even though the sun was WEFfing stolen from us this Summer for a month and a half the day after solstice. Giant bag of great quality perlite. Easy to store, even though it's big, because it's so easy to shift around. Absolute bargain. Going to order next year's bag now. About to buy next year's bag.

It can be a bit dusty, however, for the amount you're getting at the price it's a bargain! Personally I figure the finer dust can help with drainage and keep medium from clumping.

If you use a lot of perlite this is much more economical than buying the small bags from the garden centres. The granule size is variable (as described), with the largest granules probably a little bigger than those in the garden centre bags, but all very usable and I was able to mix it with compost easily to create a well-aerated mix. Inevitably there’s some dust, but so far no worse than any other perlite I’ve used (may get dustier as I work down the bag). The perlite sack was delivered inside a bin bag as noted by others and some buyers have commented on the bags splitting. So far I’ve had no problems, but the bag doesn’t seem particularly robust, so retaining the outer (bin) bag or putting it in another container is probably sensible. Based on experience to date, I’ll be ordering again when this has been used up.

Really great quantity for the price. Seems like great quality as well. Have used it in a variety of plants and no problems! Very easy to use as so light. Will definitely becoming back for more when this does eventually run out.

Great for potting seeds

Good quality and needed a large bag to mix with homegrown compost

Exactly what you’d expect, purchased 3 times now and it’s been consistent, good value for money as well, true to size, I recommend
