I have grown tomatoes, cucumbers and melons for the first time in pots with
Bowers peat-free compost. As the Bowers dries out quickly, I have installed
timed irrigation from rainwater butts. This has had limited success as the
water seems to take the path of least resistance straight down through the
Bowers. Even using a ring of micro-soaker hose in the pot, water is running
out the bottom before the compost is full soaked.

I have potted vines in John Innes compost watered by the same method without
problems.

Has anyone experience of any other peat-free composts?
Would a blended mixture of Bowers and John Innes work?
