I think the take-home messages might be these: that it's good you've noticed the relative tackiness of so many mass-produced/imported garden and home products that are readily available; that they are relatively inexpensive and don't require much labor by the homeowner--that's why they're so popular--and the alternative is either custom-build or higher-end "kit"; that such a product can still work well. That it might be a drawback in selling a home, but not necessarily for you while you are living there, so you can change that later if you need to. It might also help focus you on what you like and don't like. For example, it lets you see how you like the change in lighting and temperature created by this structure next to your house; did you only need the screen/shade function, or did you want a 4 season room; do you have trees growing that will eventually shade the area and you won't need the structure eventually--stuff like that. Meaning, if you WERE to build something, or even buy something "grander", how would you want it to be like, or different from, your Target thingy? Relative cost and delayed gratification is a common struggle for homeowners--in this case, the $200 does not appear to be holding you back were you to decide to upgrade to something else, and it's very functional for you right now; whereas, to me a common mistake is for someone to spend $500 one year for an improvement that's tacky, when $1000 would have resulted in a super look--for that, one might try to learn to save up and wait. It's also a marketing thing in which so many "things" are waved in our faces; we could afford to have one or 2 really good items or designed and built in a marvelous way, but if we want a dozen or more items--a water feature, a screen house, a patio, lots of outdoor furniture, multiple walkways, a fence, a hedge, etc, etc,--and want them all NOW, then each one will have to be the cheapest possible. And then there is the problem that so little $$ and effort is put into the outdoor features in the construction of most homes--all the things that you really need to enjoy your yard --and we buy as much "house" as we can and then only later try to think about the outside. Well, that last was a rant... You might also try to avoid continually buying the next best screen thingy--at some point, they may all share certain "temporary", or even tacky, features and a more costly one might not really be worth the extra $$, not to mention sending the first to the landfill (unless you can find a buyer). So just enjoy your current product, and give some thought to whether you might eventually want to have some much more permanent, classic structure built, or whether there's something else you need more.

Hi guys! I'm only using the greenhouse from right now until I have no worries of spring frost's...so up till Mother's Day. I too was a bit concerned about the turning over of air but in all reality, I'm only using this fan on the thermostat device so it will be running at times and at other times not. You know, it's basically just to help a little. I also have shade cloth, my new screen door which I can attach in seconds, a new wireless thermostat I ordered with an alarm feature, and also another clip-on fan. I'll admit I'm here for help and am no expert which I certainly believe Weebus is, Stressbaby, and others which I just haven't had much conversation with as of yet. I do agree now that Chris has a good point about bringing air in but unfortunately at the time I dreamed all this up I didn't have the expertise or knowlege at my disposal. I'll try what I've already done and if it doesn't work well, I'll turn the inductor fan around and bring air in instead. Currently, I bought some real nice stuff besides the fan which is a tapered unit that keeps outside rain, snow, etc from entering to the fan. It's actually really nice...I'll go take a photo and show you right now. You guys have to realize also that in my mind when you spoke about exhaust I of course thought of air leaving the greenhouse. Here's the photos: This is the outside piece that I just silicone-caulked this afternoon. There are two identical pieces of painted wood on both sides of the panel that were silicone-caulked yesterday. Today we used a hole saw to create our hole to do the work. Then a photo of how this piece has a 'flap' that opens and closes depending of if the fan is running...it's feather-light. Then lastly the inside of greenhouse where the outside piece comes in and where tomorrow after the silicone dries, I'll place the fan into which will be screwed to this 'duct piece' and then plugged into the same thermostat device that I have programmed to turn my other fan on at 46.5 degrees F. Now even though Chris may be correct, which I don't deny, I would have had to put the inline-duct fan in the middle of the hole between the two painted boards, caulked it, and put (2) of the above photo pieces (Photo 1) on both sides of it...which now leads me to think I may still do that now...ahh, better slow down here a little before I get in over my head again. Anyways, as you guys see, The hole will always be there and I can always turn the inline fan around if I need to, but I still think I may be ok. Well, start telling me what you guys think again. As you see, I made it this far with your help, and I can always change some things around as well. I'm always open to suggestions and good advice. I think I mentioned this but...the fan will be installed tomorrow after the silicone has dried. And I just remembered something else that I'd like to mention (if I still have your attention); Even though I'm sure the humididty will naturally always be there from having flats of other stuff like seedlings and cuttings in the greenhouse as well as the grafted material, the grafting material itself (the conifers) will be buried in sand to compensate me having to spray the walls down all the time to increase the humidity. What else can I say...I'm trying, I'm learning, and I'm as I mentioned willing to change anything else and to continue learning. ...Dax

As an example, CFM of 7778 will effectiveky cool a 20x20 outdoor area and it‘s suggested to hang at 9 feet. May want to look for different speeds. Wayfair for example includes the CFM info in their product details and also advises the size of the space the model is recommended for.
