Hand watering is precise, cheap to start, and forces you to look at every plant. It also scales badly. Somewhere between 15 and 25 containers, most growers find that watering is eating the day and consistency is slipping. That is the point where drip irrigation earns its cost.
What drip gives you
Every plant gets the same volume at the same time, on a schedule you set. Fertigation becomes repeatable, runoff can be measured, and the room does not depend on someone being there at 6 a.m. For commercial rooms it is not optional.
The parts, in order
A reservoir and pump, a main line, a manifold, drip lines to each container, and emitters or drip stakes. Add a filter before the manifold so emitters do not clog, and a pressure regulator if the pump runs high. Pressure compensating emitters keep flow even across a long run.
Where hand watering still makes sense
Propagation, mother plants, and mixed containers with different water needs. Many rooms run drip on the flowering tables and hand water everything else.
Sizing a pump and choosing emitter flow rates depends on container count, media, and run length. Contact us with your layout and we will spec it.
