Any recommendations for a compost to pot-on tomatoes that is not too heavy,

I've usually used J Arthur Bowers 'seed and potting', but it's difficult to
get locally and necessitates a 25 mile round trip to the nearest place to
buy, whereas I have about three or four garden centres, a B&Q & a Homebase
within a 10 mile trip to buy an alternative. I tried one different one a
couple of years ago when I couldn't find the JAB, and the water just ran
through (can't remember what it was called unfortunately).

I've wasted the best part of a bag of JAB having potted on most of the
tomatoes which developed mosaic virus so have had a good clean out and
disinfectant of the greenhouse. I've now got later ones coming on in my
conservatory which I will put out in the greenhouse and hope! I've put a
good sized test replacement from my neighbour in the disinfected greenhouse
and watching for any signs of the virus before I put the others out there.
Any advise or experience of this virus will be very welcome.

Mosaic virus isn't caused by potting compost but most likely
transmitted by aphids or even yourself having been in contact with an
infected plant.To wet compost I fill a small pot with it dry, then
slowly pour some waster on it while stirring with a dibber which works
for me.
