I go up to Canada every year for a few weeks or more!!! and upon returning from my first trip north to find my very large 6ft prickley pear laying across the patio and my aspg ferns looking like hanging straw I have learned to just let go ...and head straight to the nearest nursery. we lived in a apt then I could not believe it !!! I asked my husband (who was suppose to be watering things)why he did not water ?? ...he said "But it rained!!" Oh I'm sure it rained but these plants were UNDER a patio!!! what part of ..plant lying on ground...looks like it got water!!!SHEEESH the next year we had a house and not that I didn't trust my sweetheart but by this time I had some really nice plants sssoooo I loaded up my truck and took them over to a good green thumb friend. they all survived.I did that for a couple of years. now that I have almost everything on drip or they are established enough to take some stress I can leave them all here and most survive But there are always a few casualties. I take stock and .....head straight to the local nursery. Its the circle of life....and the only time my husband does not say anything when I arrive with a bunch of new plants!!!!HEEHEE

Ima or Denise. Personally I forget to sign my name and it isnt anything personal. Well if being lazy is personal then maybe so LOL. I also don't have time to respond to everyone nor would everyone want to hear what I have to say for that matter but I know what you mean and am sure I too have taken over a few posts. Some forums are HORRIBLE about that. I use to go to one forum that the same two individuals would always be the first to answer and then the conversation became a discussion with THEM and my question went out the window. There are also a few who are darn right mean. I hate to say it but the more organic and earthy ones are so opinionated they get really UGLY because they all think THEY are RIGHT and I just sign out. This forum and garden junk seem to be the friendliest in my opinion. Regarding your not getting a response. I posted on the gallery side of Trash to Treasures and i think it has been there several months with no response. Also I finally responded to some poor sole on Farm and Garden about his duck because no one had answered him,,,,it was from JULY!!!!!! The other thing is that our minds wander,,,, some more than others and I feel that often you will see some of that personality in a post. Like right now I am rambling and off topic and if we were here in person i would ramble and get off topic too!Wait, is that a heron outside????LOL What I really hate is when someone answers with,,, i don't have an answer but I'm sure someone else can help you. Well, why did you write?HMMMMMM I Love everyones garden names and imagine what that person must be like and why they chose that name.Afterall,we don't get to choose our birth name but in this forum we get to choose our own name.How cool is that?????? But, to those enquiring minds who want to know ,sign me Tanya

Dave -- I didn't expect sympathy. I made it clear in my initial post that I was looking for an answer from professional landscape/nursery people as to why they thought the owner I called did not want to be interviewed and featured in a magazine story. Believe me, I learned a great deal from the answers. As you say, nearly all of them were negative. Many of the posters question the value of local news coverage of their business, especially re print media. Some of them, as you noted, seem angry. They want to chew me out for either shortcomings they perceive in me or what I perceive to be a general dislike of writers/print media people, usually based on one negative experience they had with a local publication or a telemarketer disguised as a writer. I find this extremely interesting. If I used the same criteria in judging nursery owners I would never set foot in a garden center again! (By the way, I feel like I do have a hands-on understanding of what running a nursery is all about. I have worked in them, and I have done lots of dirty grunt work in the plant world, and I have been certified in a horticultural program in my region. I know plants and I know plant people.) It is also educational for me to read the sentiment posted by several respondents that they don't think I'm deferential enough, that I need to realize that I'm looking for a favor from the people I contact. When writing about individuals who own beautiful gardens, or designers whose work is outstanding, this is certainly true. But it is certainly not true for stories which are what I call 'round-up' format -- when you're looking for several business owners in a particular niche market, i.e. fitness center franchisees, doggy dare care businesses, restaurant owners, or nursery owners -- who are willing to be included in a regional look at that consumer industry. If you don't like writers or don't like the publication I write for or don't like the sound of my voice or are pissed off that I didn't drive 80 miles and stand at your counter waiting to ask you for two paragraph's worth of copy and you tell me so -- then guess what? I go to the next guy on the list. That's not arrogance -- it's reality. I have a deadline, and I don't get paid unless I meet it. And so this next guy gets his copy, and his photo, and his address and phone number are printed up in nice bold font. And maybe it doesn't get him thousands of dollars in extra sales. But for the exposure it did bring him, was it worth giving me five minutes on the phone? I think anyone would agree that it probably was. I don't have a problem with being dumped on in this thread -- it's clear that in doing so I'm filling a need for a lot of businessmen/women who need to vent. My skin is thick, and like I say, I've learned a lot from the responses. But instead of getting mad, some of you should be asking why this topic seems to irritate you so. And then also ask yourself -- is that kind of attitude helping my business? Or hurting it?

I am curious about how the actual flow rate was measured. Typically, a door opening is utilized as an instrumented flow path. At the door, one could measure by the pressure drop through a calibrated venturi, but in that case there would be a pressure drop and not only would that cut the actual flow rate of the hood, but there would be some house leakage not measured. Alternatively, if there were also a fan in the path keeping the house pressure at zero to the outside, while also measuring the flow through the fan (by whatever means), then the flow rate measured should be the static value for the entire hood system. Of course, without the test fan providing zero differential, the actual flow will be less depending on where the MUA is sourced. No magic is involved. kas Correction: In an early message above, I asserted: "A fan at the hood can more easily overcome flow resistance between the hood and the outdoors, but normally this resistance is small, a few tenths of an inch w.g., so attic and roof mount fans work fine when properly sized." I now doubt that it matters much whether the restriction is before or after the fan, as most fans have fan curves that are based on total pressure drop around the path and do not differentiate between pushing and pulling. Differences could result from turbulence interacting with structures on one side or the other of the fan, and in such cases the actual flow might differ slightly for the same fan. I don't know how VAH squirrel-cage blowers might behave in this respect.
