I’ve invested in some Westland seed sowing compost. It was on a deal at my local Tesco a while back, so got 4. You will have to shop around to get the best current deal as I think it is back up to £4.99 a bag.
So far just peppers, chillies, toms and a couple of floral bits sown in it, but I think a worthwhile investment for expensive or picky seeds.
For everyday I have come to the conclusion that all the peat frees are pretty awful unless you pay a premium, so have found my own mix. I know not everyone wants to pre-mix, but it’s affordable for me and so far working well. I got a couple of B&Q own brand 100l bags, which look’s exactly the same as Andy’s Miracle Grow, some cheap small coir blocks from EBay, some John Innes no 2 and just basic Growmore. 50/50 peat-free and re-hydrated coir, a few good handfuls of JI no 2 until it feels like it has a bit of body but not too heavy and a handful of fertiliser if I am potting on and want to get plants growing well.
First toms sown were a mini variety designed to grow indoors if need be. They are now in larger pots in my mix and I have a couple of fruits forming
If they are any good to eat they are on my list to save for the seed circle
