Alright, I think most of you know that I am a full-time FF on the side of my business. Well, I asked my partner to spray the remaining fertilizer out of the tank on his own lawn and I would clean it out the next day, today. He called me this morning to ask how to turn on the sprayer, he is a silent partner and I do all the work, so apparently the fert has been in the tank for a few days. We will now know what kind of effect this will have on the lawn, whether it will kill it or not, and we now know what the "film" looks like when you let the ICT stay too long. So, right now, because I have to get a new batch going, I am going to clean it with ammonia and then go on with my day. I hope this is the right move. Any who, any thoughts on what is happening, the consequences, what it is going to do to the lawn... so on and so on?
