How much would I need to water a 22 litre pot

What you need to learn about watering will come with practice. Here are the basic rules: Never let the soil dry out. Soil and or coco can become hydrophobic if allowed to dry. This means it repels water. This in turn will create dry pockets in the soil and the roots and microbes will die there. If your soil - coco have accidentally dried out use a surfactant to help re-wet it. I like yucca powder. Don't let soil remain soggy by watering too much too often. Root rot, damping off, molds, fungus gnats and other problems start in soggy soil. When you do water water the entire pot. How to learn when to water starts before you plant the seed. Fill your container with fresh soil/coco and weigh it (heft it) this is the lightest weight and consider it a dry pot. Now slowly water until the soil/coco will no longer absorb the water and run-off begins; weigh the pot (heft it) this is the maximum water, the wettest the pot can get. The difference between wettest and driest is the maximum water weight, for ease of explanation lets just say the water weighs 20 pounds. When the pot loses 10 pounds (half of the water weight) it is time to water again. There is an art to watering.

I used a three way soil meter to guide me as a ballpark to when the pot was getting dry. Helped me understand the logistics of everything. Then I was able to gauge it based off the rule of sticking a finger into the soil and if it’s dry up to second knuckle it needs water. My knowledge increased as I went and now I’ve graduated to picking up the pot and judging based off weight. My 5 gallon dries out in about three days but sometimes 2 if she’s thirsty, and I’m running about 1.5 gallons thru it to get 10% runoff. There’s so many variables that can change fertigation frequency so you have to find what works in your application. Man’o’green knows what’s up for sure as usual
