Hi, welcome to worm farming. I've been doing it for about a year now. Questions are good, and lead to learning more. Hope we can help out. 1. They like it best at 70, but thats not to say you can't keep them in a place that is hotter or colder. I have a bin outside, were it is 100+ during the summer and as low as 0 during the winter, and it is very active. 2. Thats a big bin. How many worms do you have? I would worry about how much air they get if you have the doors on. You would want it covered, but the fridge is made to hold air in, so if you keep the lid on, give it plenty of holes for fresh air flow. 3. Grass clippings are fine, but they can heat up. I would use in moderation. I will bag mine up every now and then, and use in my regular compost pile. Leaves, newspaper, veggie scraps make up most of my worms food and bedding. 4. As stated with the grass clippings, they heat up, so your worms could be escaping the heat. when things cool off they may find their way back. Don't let any mistakes now make you think twice about what you are trying to do. This is a great thing to do, you'll make mistakes and learn from them. Once you get it down, it is easy. You just have to learn what works best for you.

I can only answer from a man's point of view so Im sure there will be many differing opinions about the faucet difference but I would not want a faucet that just poured water straight down the drain. There might be a splash factor but when I think of rinsing dishes, as an example, the water pouring into the sink is rinsing the sink and other dishes as it runs. Additionally if you are filling the sink to wash a few dishes or other items, the water aimed at the sink will start the dilution of your soap more readily of it is playing off the sink bottom as opposed to the drain. Before I mention names of online suppliers that offer free shipping I feel it necessary, because of a recent accusation, to say that I am reasonably well known for a blogsite I maintain that is sponsored by National Builder Supply. I am not an employee, do not own it (I wish I did) nor am I paid (the owner is a good friend and I give him credit on the blog site because he does a great job and Im a satisfied customer). I am disabled retired accountant with parkinsons and I pass my days by writing the blog and reading and participating in over 30 discussion groups such as Garden Web and just enjoy helping folks. With that said there are many sites that give free shipping on merchandise, including NBS, but most have a requirement for a certain purchase amount usually $100 to $199. Watch the sights carefully because the prices can seem low but by the time you get done with your shopping the freight if not free at some level can make the price exorbitant. Now so that it will be obvious that I am not prejudiced to just NBS, my experience level and the retailers that I hear the most good about that have these free shipping policies are NBS, FaucetDirect, E Faucets. Im sure there are many more and you will probably be swamped with other suggestions but I believe reputation wise those 3 are the best. And no I also am not employed nor own any of the other 2 either...LOL

It would help to know in what context the word judgment was used.

Not an electrician: I believe the NEC prohibits using ducting as a wireway (conduit) because it is not approved for the application. There are also requirements on cables and conduit when in an air plenum, such as a ceiling used as an air plenum. Truly abandoned ducting is just metal surrounding a cable or conduit run. If the duct is greasy, then any conduit in the abandoned ducting should be sealed, and in my view incapable of supporting a fire, such as thinwall, IMC, or rigid. Flex might allow grease to intrude upon the conductors. UG cable might be OK. PVC conduit might be allowed. I have never noticed this particular case addressed in the NEC. For electrical questions, I argue that it is better to ask permission than forgiveness. See your Code Enforcement officer for advice. You may have to tear out some part of the ducting at each end for it to qualify as abandoned. I think it is a good idea, pending approval, if the duct is buried and the path needed is otherwise inaccessible without trenching under the building.
