I am relatively new to gardening, and being disabled and on a tight budget, tend to read any reviews of stuff before I buy - you gardeners seem a very honest and passionate (about gardening!) bunch. If you look at the most recent reviews on both the B&Q and Wickes websites, all of the RECENT reviews say what complete rubbish this is.
Like I said, I am fairly new to gardening, and trying to raise a lot of things from seed to save money (flowers as well as veggies). The best results I've had so far are with the Jiffy plugs, where this is a bit of compressed stuff that you add water to, then sow the seed, great in my opinion, as I know when I can see roots, I need to pot these on. However, the potting on has been a bit hit & miss, the first bag of potting on compost I got was ASDA's own, which was good, the next 3 bags I bought were not as good though. Next I've gone on to a massive bag of Levington's, which I thought I'd be OK with, but I wouldn't even TRY to sow seeds in this, there are big bits of wire and fairly big twigs in there. It's OK for potting on, but too coarse for seeds (not that I really know what I'm talking about).
If I hadn't read about how rubbish the b&q and Wickes stuff is, I would have bought it, had everything die, and probably been put off gardening for life. If anyone wants to start a 'grow your own compost' thread, I'd be really interested.
