Step 6: Fill the trays with water and put your plants inside
Fill the trays with water and put your plants inside. Duckweed on the top of the water reflects heat and helps prevent evaporation, and looks nice too...
Step 2: Saw the pallet in half
Pretty self-explanatory - cut off half of the pallet. I picked the nicest half to keep, and cut off the more broken side. I kept the 2x4 in the middle so that the tray would have extra stability if I had to move it around.
