Vermiculite

Vermiculite is a brownish coloured, spongey particulate that can hold 3-4 times its own weight in water. While still retaining great drainage and air content, it helps to improve the water holding capacity of a substrate, reduce compaction and improve the overall conditions in a variety of situations. Due to it's makeup, it acts as a natural source of silicon for your plants too. Vermiculite is something that is often compared to perlite, but it's properties are actually quite different to its pearly white cousin. Although it is made in a similar way, the resulting physical properties are quite different and can be highly advantageous for a variety of hydroponic grow rooms. It actually works best when combined with perlite to form a high performance, often under-rated hydroponic medium!

How To Use Vermiculite

Vermiculite comes ready to use, simply open the bag and pour it out and use it! No pre-treatment is needed of any kind, so no extra work involved other than a quick mix into the substrate. As a standalone product it retains quite a large amount of water, and so is usually best to use as part of a peat or coco mix to aid with the overall water holding capacity. It is most commonly used in combination with perlite at ratios of anything up to 50:50. Depending on your overall circumstance the ratio can be tailored to your exact needs, depending on plant type and of course environmental conditions in your grow room. A mix of 50:50 vermiculite to perlite is a common method used as a substrate in propagation when rooting cuttings. The mix makes an effective rooting media through the combination of the two distinct properties of the substrates. Try it, you won't be disappointed!

Vermiculite is available in 100L bags.
