Those will work, just set them up right and you will be good. There is a lot of info on mixing soil. A good soil mix and straight water is a great way to go with blumats because the lines are small and will clog with any buildup. Also you don’t want your reservoir to ever get dry or you will get air in the lines so put it on a float valve and a timer to fill. I used blumats for a couple years, 10 years ago, and they work but to me nothing beats cycle timed feedings especially now that you can adjust them remotely with a phone.
