Low Temp + High Temp = 100 deg F
Comments (11)Interesting Stuff...thanks for the responses Here is what I am facing (in Western Oregon) Yesterday... LOW 29 HIGH 45 OK, to me neither the soil temp or the air temp would be conducive to plant growth...even a cool weather crop, such as peas. Under these conditions, it was not raining but the sun didn't appear until late afternoon so things never warmed up. I have been gardening for (only) six years so my experience is limited, but my observation is that peas planted at this time do not germinate well...therefore I went to starting them in cell trays. They are my unheated greenhouse now and are growing some there. I would say yesterday's range in there was (like) 34 to 65. I don't want to go to "analysis paralysis" ...but there might be a useful quantitative number that I might use...any other thoughts welcomed...See MoreHigh temps and humidity?
Comments (5)Solar GH is sort of right. A simultaneous temp of 125 with 97% RH is almost unheardof. This translates to a dew point of 124F. That is not sustainable. Is the monitor working? Could it be in the sun? Near a heater? Solar GH has it backwards when s/he said, "the higher the temp the less the air has the ability to hold water." Actually, the ability of the air to hold water goes up as the temps go up. However, the absolute amount of water vapor in the air doesn't change that fast, and this means that when the temps go up, the RH goes down. Your 125F, 97%RH, assuming those numbers are right, is not sustainable because as soon as the sun goes down, the temp will drop below the dew point of 124 and all of that water vapor will condense out. By morning, the absolute amount of water will be much lower and as the temps rise again, the RH will be much lower. High temps will increase the transpirational stream, and that is necessary for cooling. But high humidity will decrease the transpirational stream, limiting the plant's ability to cool and eventually resulting in nutritional issues. This thread by greenhouser contains a little essay I wrote for another forum (pasted in about 1/2 or 2/3 down the thread) on GH humidity and you might find it helpful.

Comments (2)Cilantro and other 'herbs', just too numerous to mention here without going into a very lengthy answer.. Suggest you FIRST decide what you like as to an herb. There literally hundreds of THOUSANDS to choose from, and many have specfic requirements. Sugest you get a good book on he subject too. Keep in mind your same question is posted here by many people and soem know what they want to grow, as opposed to wanting to knw what grows well or not. Good luck! Oh, another help, once YOU decide on what YOU like, and want to grow, use the SEARCH window at the bottom of the herbs pages for gathering further info....See MoreNeed help troubleshooting a/c- temp ok, humid too high
Comments (7)"Also have checked the drain lines - no clogs, and in fact, the drain pan has been dry." " So when I say there is not water in the pan, I was referring to the overflow pan. There is water in the pan inside the unit under the coils." Did I mention , you are overlooking, omitting or mis-stating some fact(s). ??? And there she is plain and simple. With that straightened out I'll stick by my initial knee jerk,leaking return. Useing a sensitive and accurate thermometer,record air temp at intake GRILL and then record temp immediatly before air enters blower. If you find more than 1 deg differential,investigate for return leak and/or poorly insulated return. You will get advice about load calculations and such more suited to trained pros but do the simple things that better fit your wheelhouse before getting that deep. There's a recent trend of pulling all the stops regardless what the complaint is. Here's something to consider. It is plenty hot and humid in Houston Tx where many systems are intentionly oversized. It's hard to find people complaining because their ac is too large. Until you reach about 30% oversized,the biggest difference is increased operating cost. If your place call's for 3.5 tons cooling you will not complain about being uncomfortable with a 4.5. If it were so simple anyone could tell you the problem, techs wouldn't have to come out in person to figure these things out....See Moreelgrillo
