If any of you are following the Indoor Temp thread you may know that I've been documenting my Greenhouses average temperatures over the past year, along with my backyard. For reference I live in the Cascade foothills of Pierce County in Washington state at 775 ft elevation, about 24 miles from the peak of Mt. Rainer as the crow files and my greenhouse is (25ft(L)x9ft(W)x9ft(H)). cdweather.boards.net/post/271799/threadI ended up making climate tables for the predicted 20 year average for my greenhouse as well as my backyard using the official recorded data at SeaTac airport of that same month and finding the difference and then adding that difference onto the 20 year average of the airport. I don't have any data for rainfall as i don't have a rain gage, but I do have the humidity stats, but I just used the humidity of the past year, I didn't really bother with trying to extrapolate the 20 year average. As far as projected rainfall, well for SeaTac you would obviously use the official statistic (39.4 in) and for my backyard, it will probably be similar to something like Issaquah which gets 62.19 inhces. en.wikipedia.org/wiki/Seattle#Climateen.wikipedia.org/wiki/Issaquah,_Washington#Climate So how do you rate the climate tables below and which one do you prefer?  |

Nice thread idea. I'm gonna go with the greenhouse. Seems like it gets a lot of fake heat had it been an outdoor climate, but I'll take it for the warm daily highs.

Back yard, cool thread idea. What do you use the greenhouse for?

Why are the means for the greenhouse so far off from (high+low)/2? Also what's going on with the September high?
I choose the greenhouse if it's an outdoor climate that gets rain.

Back yard, cool thread idea. What do you use the greenhouse for? I use it mainly for growing for growing tomato starts, but also grow cucumbers and peppers during the summer in there, it's my first year so still experimenting what I can actually do there. For example I tried to grow a few tomatoes there in the summer and stops producing, but does well in the spring and fall months. I also tried to grow cantaloupes and watermelons in there, but my fertilization rate is very low, I think it's because pollen becomes sterile at temperatures over 90F? |

(high+low)/2 gives you the median, not the true average. I have timestamps for every minute, so when I calculate the actual average, it's significantly lower, for example here is a chart for July 1st. Also if you notice mornings are relatively cool in the greenhouse, it only starts to heat up around 11am.  As for why September is so high? There are multiple factors, one has to do with the sun angles. The roof of my greenhouse is made of white plastic which blocks out about 50% of the sun. The south wall is made of a clear plastic, so as the sun angle gets lower in the fall more sun light comes through the side wall. Another factor which I think is the main one, is that in late summer/early fall I started to switch tactics and would try to hold off venting as much as possible, otherwise the humidity would plumet to bone dry conditions and I figured the plants could tolerate humid heat better than bone dry heat. For example here is the hottest day recorded, September 15th at 116F.  and here are the actual averages recorded for the past month.  |

Backyard, based off my not completely fluent grasp of Fahrenheit

Seattle is def. the best.
I do find greenhouse climates interesting mind you, but not fit for living in. I am thinking of getting my own greenhouse next year, and measuring the temperatures in it, to see what I record.

I think you all know what my answer is, lol.

Backyard for having wider diurnals than the airport.
Having a whole month without dropping below 84% RH is a foreign idea to me...wait, is that daily mean or the lowest hour/minute value? Looking at it they must be daily mean. Surely you get some humidity readings below 30-40% in summer afternoons during heatwaves.
