I only have a 8x6 greenhouse, so I have to pack it in there. It is my place to grow toms and peppers; as well as my propagation and cutting area, and I also overwinter things in there so it has to be multifunctional.
This is how I grow cucumbers I have a large old recycling container, sat on a large flat tray. I have 7 cukes in there, and all climb up twine to the roof. As the cukes grow, I trim off the lower leaves, and will hand pollinate 1 or 2 fruits from each once they are in full swing.....which means very careful bagging and poking as cuke flowers are very small and tricky to handle.
I also grow on 2 levels; so I have big trays on the floor with toms in big pots. These are trained up behind the staging and onto twine up to the roof. The staging has peppers at the front, and a few toms at the back in smaller pots, again trained up twine. All leaves are taken off as they grow so that I can fit more plants in.
These are my spare peppers and toms. The toms are all from armpits from my main toms, and will either go to schools/community growing areas that I am working in or will go under my main tom frame at the lottie - they can grow lower to the ground as they are armpits and as I have mulched the ground under my tom frame at the lottie with straw, the toms can just go wild under there and grow almost like strawberries. The peppers, will all go into spare pots around the garden or get given away.
