It can be kind of tricky to get just the right tightness. Are you using the bottles inserted directly into the soil? I believe the leaking water can mud up the soil around the cap which then seals the cap and prevents more water from dripping out. If the only flow rate you can get is one bottle per hour, that's actually still not too bad of a system, because it applies the water directly into the soil instead of pouring it from a container (which can wash away soil at the spot you pour it) or spraying from a hose which wets the entire plant and which can cause sun burn or other issues with the leaves and stems.
It took me a bit to fiddle with each bottle to get a consistent drip that didn't clog up and stop too quickly or that didn't just drain the bottles too fast.
