i would avoid relying on the blumat system you cant imagine what a disaster it is if you get a leak or overwatering, usually it will overwater the plants, i use it only when i need to travel for like 2 weeks or more , but most of the time it fails. i had some success with bottom feeding, but the best for fast growth has been top watering as nature intended. Just a bit of my personal experience ! Hope this helps ! 🚀
