Cloth pots and watering

I found fabric pot are best i would concentrate of giving them same amount of water every other day like 1-2L depends on size and stage ,and then roots will just suck it up in no time ,hope thats help

A few factors at play with your watering frequency. Type of substrate and it's consistency play a role. Environment matters, aka a dry environment increases evaporation. The size and demands of the plant matter too. As others have said, watering in more slowly helps with escape from the sides. If growing in coco, increasing watering frequency helps too. Coco absorbs and moves water better when it's still wet and becomes hydrophobic if it dries too much.

More about size of plant and it's rate of drinking... You'll get slightly more evaporation with a cloth pot, but it shouldn't be too signficant. is it too fluffy/airy? You can go too far. High water capacity substrate only needs 50% perlite or similar. Coco only needs 33%. If you have too much, it increases frequency of fertigation unnecessarily. Well, not all the time.. it's a way to dial in frequent fertigation methods to ensure enough dryback can occur to warrant 3-4x/day fertigation. I've never had an issue with water coming out the sides. If that's happening, water more slowly. Let it absorb without creating a pool of standing water on top. Next time tamp it down a bit more and that can help with even water absorption, too. When i fill my pots for a transplant, it's on the dry side so it's impossible to compress it. I just make sure there are no gaps and evenly tamped down. Water will take path of least resistance if it exists. A quick getaway out the side could be as simple as that... a crevice that exists or after the fact eroded to exist. Also are you fully watering or just giving some volume you whimsically choose. Always ensure tthe entire volume is saturated. Dry pockets are the devil!

12-15ltr pots with a half decent sized plant will use 2ltr every other day which is what mine get in 15lts,4 gal.They say its best to do it every other day as opposed to 1ltr daily as the dry periods encourage the roots to explore.

Same advice as Hashy. Till plant leaves didn't touched verged of pot - amounts should be adequate for plant to last 3-4 days. Water outer circle around plant and a bit under stemp. Divide amount into 4-5 parts, give 5-10 mins before adding next part. Wet/dry cycle is a must in soil. Ph is essential in soil. Collect run off and throw it out, font let pot to reabsorb it back...

Try watering in smaller increments with a gap between, that way the water has time to be absorbed by the grow medium. You will find then that the whole pot gets filled rather then running out the sides and bottom straight away.
