I use iodophor (more or less, I use iodine solution for sanitizing (yodogen plus) ) and I do use it for anything around the house once the color has gone due to exposure to air (as in an open bucket)... I have added it to tomato plants and the plants appear to enjoy it (no negative effects). If you have solution with a tint of color, covering it with a sealed lid will allow it to maintain it's effectiveness in destroying contaminants.... it loses effectiveness when exposed to UV or Air. It keeps it's power when sealed from both. I am sure it can inhibit microbes and components in the soil, however it does become much less effective with time exposed to air and UV. I will continue to use it to water plants because I trust that it doesn't damage anything once the concentration is less than visible (<10ppm) in my case. I also use my trub, diluted with water.... to give nutrients to bushes and plants. so far.. the fruit bushes I have placed the diluted trub onto... appear to really flourish. my opinion, my usage... but if it is something very important to you (the fruit or veggie).. than I may be a little more careful.
This is very helpful, thank you! How big are your batches, and how much do you dilute your trub with? Do you notice an increase in slug/snails with the yeast and hop residue on the soil surface?
my batches are 12 to 14 gallons, the trub is not significant as I use a hop screen for the hops, which are contained, the remainder of the trub is diluted with only about a gallon of water, just to rinse the kettles prior to cleaning. I just add water, swirl and toss onto my fruit bushes... I had not noticed any more slugs/snails than what is normal prior to using these solutions. same with the fermenters, I add water, swirl and toss.... so the trub and yeast water mixture reaches the base of the plants. I have blueberries, golden berries and a lot of additional local fruits bushes which I don't have english translations for. all the plants flourish nicely with the additional nutrients.
Naaa. I used to do that with my last dog...of course that was back when I only drank from the conveyor belt. I don't think I'd do it with an IPA but as Hawkbox says, it's the concentrated stuff like the pellets or the green overflow from the kettle after you add the hop addition that are harmful.
