Hi to all. Here is a link to the Product that I am using http://www.wormsway.com/detail.asp?sku=BIS700 The nicotine is a very interesting idea, does it discolor or leave any taste? I gave my plants another spraying last night and tonight I will pull them out and give them a good lookover! I noticed on the worm way advertising of this product that they say it can be applied up to the day of harvest?????? I am still concerned about having to rinse. It is starting to get cold and rinsing in February might be challenging Thanks Kindprincess for the great info......G
