Fyi, Was thinking about growing some hydroponic tomatoes this year and took a trip over to a local hydroponic supplier. Hand't realized how big an industry this is these days. But I am sure its not for tomatoes. Well, there on the shelf nex to the Super Bud Juice and the Earth Gold Super Grow nutrients were quarts of 27% peroxide. I didn't see the price and then forgot to ask. Didn't have etching suplies in mind at the time. Craig [Non-text portions of this message have been removed]
