Rain, plumbing issues, and peas, Oh My!

So we had a few issues with our newly filled grow bed. The Bell Siphon valve jammed closed, which resulted in the bed almost overflowing. The valve triggered just in time (no pics alas). In a separate event, last Wednesday, we noticed the bottom tank was leaking, and in response we turned off the pump to avoid the pump running dry. The next morning we turned the pump back on, alarmed that the plants seemed to have suffered considerably overnight from the lack of water. The rain over that night seemed to have done practically nothing to help the plants, and may have even harmed them (see the picture below of the abrasion on the stem). To end this post on an up note, The peas we planted a few weeks ago seem to be doing fairly well!

Current state of the grow bed

These abrasions may be related to the rain we've been having lately

Surprisingly the wind hasn't damaged the peas

Sad tomatoes
