No worries buddy. It's pretty simple
The bottle:
The cap:
The parts:
The general idea:

It's not connected in that picture. The hose just goes through a hole in the wall and is connected to the bottle cap.

Splitting the feed twice is unnecessary I've found. A single T piece and two outlets is fine. You can also just put the hose through the hole the plant grows through and place the outlets on the surface of the medium.

I've been watering every fourth day about 2.5 litres each time. I would not recommend doing this and I'd suggest watering every second day, I suspect my recent problems are related. Letting the waste evaporate is fine but the drip trays get pretty filthy. I usually actually drain the trays with a 150ml syringe and dump it on a potted plant in the garden.
