Best RAINPOINT settings for early growth?

All good. I also had to do this recently, I had 20 days. I set up automatic watering to water every 2 days. But to know the necessary water continuity, I set the watering system to work and timed how long it takes to water the pot until it drips at the bottom, just a few drops, no runoff. This way, I was able to get an idea of the watering time and also the amount of water. I hope this helps, happy growing!
