Hi Ya, I use Jacks Magic. Having tried several different ones I find that the best and most consistant. I have tried the peat free but found they dried out to quick and took a lot of re hydrating, not for me I'm afraid also some of the stuff in the ones I tried was a bit dubious. I have used ASDA's when I need to bulk something up as Jacks is to good for general use. I also find that some of the so called on offer composts aren't all that good when you get them home. You gets what you pay for I suppose.
