I have seen multiple posts on this list about using smoke water to stimulate germination of certain species. Does anyone use it to enhance growth after germination? I recently came across an interesting article in which commercial onion seedlings were watered regularly with smoke water. It had an impressive effect on growth, compared to plants that did not receive smoke water. After 175 days, the plants receiving smoke water had more than twice the bulb mass of the controls. If this response is common among geophytes, it would be quite a benefit. Have any of you tried this? The article citation is Kulkarni et al, Effect of smoke-water and a smoke-isolated butenolide on the growth and genotoxicity of commercial onion, Scientia Horticulturae, Volume 124, Issue 4, 1 May 2010, Pages 434-439. BTW, I am a new member of PBS. So far I don't grow any bulbs that are particularly interesting or difficult - mostly just easily purchased things. Bill -- William A.
