Iv been using Airpots now for 2 years, and iv found they work best with pure coco, as coco has that sponge like texture. You have to take you time slowly watering at first but as the plants get bigger and have bigger root systems, feed will be absorbed instantly, you to over excess feed to get a run off, you don't get feed pissing out of the holes, I pore my feed into a 2L jug and then into a small 1L plastic watering can, nice and slow feed.
For me coco and Airpots are the perfect coco, 3L are fantastic at getting small plants root systems goings, ideal to transplant straight into a 10L or 15L for indoor.
