I broke a month old WW auto. About 95% broken, just a little bit hanging on, and broke it just above the second node! I stood it up, tied it with yarn and a little electrical tape. She healed in three days, but there was no growth for about 25 days. THEN, she exploded. I had two plants, the unbroken one have me 30 grams. The broken one? 168 grams! DRY!
Wish I still had the pics!
