Everything survived another week except one spinach plant. An insect,(I'm betting a caterpillar), chewed off the main stem right at the level of the Hydroton. Everything also actually grew like crazy in spite of the heat.
I have just been draping the 40% shade cloth from the back of the unit to a couple of ropes just enough to keep it off the plants. Going to come up with a more permanent solution this coming week because it seems to be working, even for the lettuce:
In fact the lettuce did so well the misses chopped it back right after the pics above and we have enough for a salad tonight:
Will be interesting to see how much it grows out this coming week since it is cut completely back to the level of the Hydroton.
