Now, the ground is not the best, so I would be building a raised bed
inside the greenhouse and filling it with potting mix, compost and
manure.

Sounds like a good choice -- plants usually grow best in bigger containers
than most pots.


The potting soil I've used most in greenhouses is equal parts good
topsoil,
chopped sphagnum or coir and sharp (builder's) sand, all steamed. Add
lime as needed to correct
the pH. Just about anything grows pretty well in it. Amend as needed
to meet your growing conditions when you've got more experience.



Steamed? Why and how? What if he needs an quantity we might describe as
"five bath tubs full"?
