Last summer I gave a short presentation regarding my greenhouse set up and while I was compiling photographs to illustrate my presentation it soon became clear, my green house was becoming a mess. I had to retake photos avoiding all the detritus which had built up over time. I was well overdue to clean up the house. The dirt on the floor became slippery and a hazard but also reduced the reflective light. The algae on the poly-carbonate also reduced the light levels. Pots were squashed precariously on pebble trays. Due to the limited space many of the larger Oncidiums are hung from the roof giving them plenty of light, air movement and drainage but this makes it difficult to reach many of the plants below them. In this section the orchids mainly sit in gravel trays which is not ideal and I will need to place layer of mesh between the gravel and the pots
