@leeowen, good morning, sorry we couldn't connect yesterday.
As @Norm mentioned, the IFTTT recipe to water every hour for sod could be used for your new seed. I'd be happy to help you create your own recipe if you'd like the settings to be different.
Getting back to your nozzles and precip rates, are you using these nozzles? If so, I'm concerned we might have the wrong precip rate as I believed you mentioned you were using rotors that are set to .36 in per hour, but the 6 nozzle will output .57 to .84 in per hour depending on your system's pressure (PSI), flow (GPM), and the head's radius (ft). Output .57 to .84 in per hour assumes a flow of 4 to 7 GPM, which shouldn't interfere with your well or AM shower. The best way to find the exact precip rate is to perform a catch cup test and then create a custom nozzle to match.
Is this a custom blend, or did you purchase pre-mixed from a lawn and garden store? I only ask as I'm curious if you have a 50/50 blend, 80/20 blend, etc.
Remember to do the following if you haven't already:
Mulch with a weed-free straw, such as wheat straw. As an alternative, you can use a seed starter mat or seed blanket to help keep the seed and loose soil from washing or blowing away.
Water frequently to keep the seeds moist (don't saturate). Cut watering back to once a day when the grass reaches about 1 inch in height.
- Mow when the grass reaches 2 1/2 inches - 3 inches.
In general, with seed, you need to keep your soil moist for two to three weeks. Re-water when soil looks dry on top in mornings. Do not allow water to pool or it can create dead spots. It is best to water for short periods of time while establishing, keep moisture on the upper level of the soil where the seed is planted. After the seedlings emerge you can start to reduce your watering and let the soil start to dry a little more so the roots will grow deeper in the soil as the plants get more established.
Let me know your thoughts on the precip rate and well as your current watering schedule for the seed.
