Am about to put up a new greenhouse on a base of railway sleepers. I have a long plastic planting trough that is about 1.5 feet deep and would take up one whole side of the greenhouse. Because of it's height, it would bring the level of the soil above the sleepers.
Apart from the fact that I may need to water more often, ( and fertilize/renew the soil in the pot ) are there any other advantages or disadvantages of growing greenhouse veg in pots as opposed to straight in the ground that I might not have thought of?
I was planning on growing tomatoes, melons, squash ... maybe a grapevine...
