Often times people report there is a significant difference between front and back soil. This could be due to excavation from the home being piled in one or the other and then spread or topsoil turcked in for the front but not the back, or in larger yards it could be natural occuring differences from historic deposits. Use observations to help you decide. If you do not see significant soil type differences and you have not seen differences in the same turf grass between the yards (for instance yellowing KBG in the front but not the back), one test should be fine from samples from both yards mixed together. Next year, if you are seeing significant differences in the front and back turf, you can get separrate tests. I initially used only one test and it worked fine for me. If I had seen differences between my turf after the first year, I had planned on going to two tests. There is a government geological site that maps soil types and in some instances mapping them to allotment level. Sorry but I can't seem to find the link in my bookmarks, but I'm sure if you google soil profile mapping you'll find it. Soil type is only one variable to consider though.

Hi All, These two photos are from my flickr account. Would anyone who use flickr please tell me what private setting I need to set so that the viewers on this forum, when double-click on the photos, can only see these two photos but not all photos in my flickr account? Thanks J.N

Hi All, I need some assistance with IAQ installation. I called Honeywell and setup the R jumper to the DHM1 and DHM2 to BK on the A/H board. We turned off Comfort-R for now on jumpers 5 and 6. I pulled out my hand dandy multimeter and measured V at DHM1 and DHM2. I'm measuring 23.x V from DHM1 like I would espect? Also, I would think that I should be measuring lower V at DHM2 when the system is trying to lower humidity, but I don't seem to be. Still measuring in the 23.x range. I have the Stat set for 1 on 370 and 379. I set the humidity lower on the stat as well, but I don't see any voltage drops on the EIM to signify the stat controlling fan speed. What gives? Anything else I can check or I could be doing wrong? I noticed there was no jumper between R and BK on my A/H board already and nothing hooked into BK at all. So I ran the DHM2 wire to the BK connection on the AH board. I've checked for posts in history and it seems I'm doing everything right. I understand the IAQ only lowers fan speed 80% and it doesn't lower voltage that much? I think at one point I did see it at 22V, but I'm not sure now. 80% doesn't seem like very much. Makes me wonder if the IAQ DOD is really better then Comfort ramp up schedule. thanks all, Dale

It was my understand that a subject title had to be at least 15 characters....not that it was limited to that. And 15 characters seems very arbitrary ;-) Another little Houzz annoyance.
