So far, buying the greenhouse has been a bit of an extravagance. As well as the greenhouse itself, there was the cost of building a concrete base, and paying someone to assemble it.
But from now on it's going to be re-use and recycle - in other words, a return to my usual cheapskate style.
So instead of buying shelves from the Greenhouse People, from whom I bought the greenhouse (although I must admit they look rather good), I made some myself from leftovers.
Now I'm starting to get an idea of how much I'm going to be able to fit into the greenhouse. My son says he wants to see every cubic centimetre filled with biomass. I'd rather aim for a kind of scenic grotto with enough room for a human being to visit comfortably, or maybe even to sit and read in pleasant surroundings.
