The short answer is no, don't bother with it. Vermiculite will keep the soil wetter, which you don't want. Perlite on the other hand is great to mix into the soil, it helps with drainage and airation.

thanx for that mate.... in the bin it go's lol

if you're using soil i like to mix some in with perlite as well. a ratio of 70:20:10, soil to perlite to verm. just my $.02. If you need to raise humidity fill a cup with verm and water. You can grow in verm only but you wont water as often, which ultimately means less nutes. so it's your call. If this is going to be your only medium I wouldn't use it

I called my local hydro shop and Home Depot, here in the states about Vermiculite. They both had the same answers about it. They said that they have all but stop producing it and have pulled the product they had because of the carcinogens contained in it. Just a friendly word of warning.
