The cover came out nice and neat. Looks like it will work great.I put cardboard covers over the soil in both SIPs. Thinking this may reduce evaporation - it will be getting hot here next few days. I took a bucket lid and drew a circle on cardboard, then cut out the disk about a half inch inside the line I drew. Cut the piece in half and notched the center where it meats the stalk, and also notched where the fill pipe is. Easy to remove if desired.
Found this tiny praying mantis - hope he is eating good.
I topped 4 of the ladies again today - left Watermelon on Critical Kush as they were (topped only once).
