Assembling an automatic watering system for indoor plants, a question?

Hello!
Summer is coming, the season of holidays, barbecues, recreation! Well, how soon, after 4 months)
And therefore I want to assemble an automatic watering system for several indoor plants, and use a soil moisture sensor for each flower.
But! There is one caveat, the flowers will be different, in different pots, and therefore they need different amounts of water. How to make it so that you don’t have to connect several pumps, but connect one pump to each and every flower to give the amount it needs.
How to do it all for one flower, I know, but how to do it for several, also with different amounts of water, this raises questions ...

if there is 1 pump and a collector, then a different amount of water can be provided only with different hose diameters. And you can’t water one, but you won’t be able to water the rest. Although there is an alternative - to put valves. I haven’t seen controlled ones on small tubes, you can farm with servos.
so I would still do it with separate pumps - good, it’s not expensive
, well, and 1 more argument FOR. if the pump dies, only 1 flower will die.

Нужно использовать коллектор с отходящими шлангами.
Можно попробовать подобрать диаметры трубок к каждому горшку отдельно.
Или диаметры пусть будут одинаковые, но необходимые трубки пережать или другим способом уменьшить сечение.

Самопальный циркуляционный насос из маленького вентилятора 12В (например такой). время до лета еще есть, можешь собрать на каждый цветок по насосику

причем для каждого цветка использовать датчик влажности почвы

У вас неправильная постановка задачи. Что делать, если в одном горшке влажно, а в другом сухо?
