One of the more interesting greenhouse chores each year is my early spring cleanout of the panel bottoms on my hfgh. The panels on the roof always end up with a kind of green slimy mold at the bottom, and I scrub them out and sanitize them each year. Today was the day.

I detached the panels which are screwed into the frames, undo the clips, spray the bottom and sides with Tilex mold and mildew remover (or with dilute Physan), and use a toothbrush or tiny screwdriver to clean out each tube. I then wash down the inside of the tubes with water, and reassemble the panels on the frame. I'll then wash down the inside of the greenhouse with Physan (next weekend) and be ready to plant.

What do you do to sanitize your greenhouse? Jim
