00:00When it rains continuously for three days during the monsoon, how will the drainage system work? The water is constantly falling.
00:06So, even if water drains out of the drainage hole, new water will quickly take its place.
00:12So it is still in the water.
00:13And this question reveals the most interesting science behind this entire process. Drainage simply means removing the uneaten money.
00:21It's not packaging. Well, what else is it? It's basically an active aeration mechanism. When gravity
00:29Or gravity pulling the water downwards
00:32When the water flows out of the drainage hole, the water sliding down creates a negative pressure or vacuum inside the soil.
00:41is created. And that vacuum draws fresh air from the surface into the soil. This is its entire
00:48That's great. As the water flows out the bottom, it fills the empty space behind it.
00:53It draws fresh oxygen in from above. This means that every time the water is drained, the soil literally becomes a new
01:02She takes a deep breath. If the water remains stagnant, this vacuum will never form. It's like a mechanical lung.
01:09It's working like a water drain. Absolutely. I mean, drainage isn't something passive, that just...
01:14Water is seeping out. This is an active pumping system that keeps the roots alive. This is why the monsoon
01:19It is most important to have a brown soil with good drainage. If the water drainage is proper, then whether
01:26No matter how heavy the rain, the process of water flowing down rapidly
01:30It will continuously deliver fresh oxygen to the roots. Absolutely right. So, this entire discussion has completely changed the way we look at gardening.
01:38It changes. Watering isn't just hydration; water loss is a form of breathing.
01:44Yes, of course, there is respiration.
