I saw that Dan Carlson on one of the HGTV shows last week, and looked him up on the web. Very interesting. It makes sense about the stoma or whatever being open in the morning... but I can whistle myself. I'm not saying that it won't work... heck, I've still got some Spray and Grow around somewhere, and last year I bought something 'totally natural'that turned out to be oil field chemical that killed one of my gardens. This time I think I'll wait until somebody tells me it worked for them.

Hi

this response is two years later!

I have used Spray and Grow for years - and I was completely skeptical until I tried it. But I tell you, it sure does work! Plants that have just sat there and done little, will immediately within a few days put out new growth and the blooms you get are far better than without. And now they have a sea mix foliar spray you can use with it.

I know what they say sounds like snake oil --- but I and everyfbody I've shared it with think very very effective. I think they have a web site.
