That means extra watering when it is really needed, what was suggested in earlier posts. If the allowed depletion level is considered ‘zero’, then Rachio should track the water deficiency in the zone, and replenish the deficiency the next time the zone is watered. If this transpiration is not accounted for, then over time, the zone will always be in a water deficit. This can happen if the forecast on a watering day underestimates the Et before the next allowed watering day. In reality, even after you hit the allowed depletion level, the zone is still losing moisture via transpiration that needs to be replenished the next time watering is allowed. The biggest flaw that I see about daily flex, is that the allowed depletion level is considered the ‘absolute zero’ moisture level for the zone. And additionally training the roots to grow deeper to get water instead of being shallow.
#RACHIO CHANGE COLOR DRIPS SCHEDULE FULL#
Rachio will increase the frequency of watering, not the duration - as once the root zone water table is full adding more water is not efficient. Let me know if I didn’t answer the question as I do believe Flex Daily does incorporate auto changes. One suggestion is to start out with one or two zones on Flex Daily to get the system dialed in and then move the other zones over to Flex. Rachio is very sensitive to GIGO, so make sure the soil type, precipitation rate and plant type are correct before going on a 2 week vacay. I believe the Flex Monthly uses 30 year averages that are recalculated every 10 years. Likewise, if abnormally cooler or wetter weather occurs or is forecast Rachio will push out the watering. So, if abnormally hot or dry weather occurs or is forecast Rachio will water when it is allowed to. Thanks for your response in - I believe the Flex Daily option uses observed and forecasted evapotranspiration and precipitation to determine when to water. In this last case i would return this new unit to Costco… Otherwise I will have stick to my current system which DOES have this feature and forgo all the other goodies the Rachio has to offer that really do like. So I need to know now if you are working on incorporating a temp based auto increase/decrease watering time function in the 2 FLEX choices ? And can this be implemented in the V3 firmware/software ? if so I may be able to wait for this functionality. Also past years history for monthly flex setup means nothing here In Socal… Last year for instance June was abnormally cool when july jumped to ridiculous temps of 116 degrees
We have a 3 day water restriction, so flex daily set to 3 day could end up to be problematic during a sudden 2 week extreme heatwave ( this all of course while I am away on vacay and dont notice the grass dying).
#RACHIO CHANGE COLOR DRIPS SCHEDULE INSTALL#
HOWEVER, after install and complete setup, I now found out that the both “flex” schedules do not have a way to incorporate auto changes in daily watering times based on fluctuation of temperature. Just bought the V3 unit at Costco and was initially very impressed with the features and functionality and flow meter stuff !
