Thanks DH, I tend to use coco in the same fashion you do. When I first used it I treated it much the way I had soil, but over time, I moved to methods more in line with hydroponic principles, eg) continuous access to nutrient solution and feeding with greater frequency to maintain moisture levels.

I aim to feed daily, I do have a foursome flowering in 6 litre (1.5 Gal) pots that are feeding twice daily, but even for me, that is a bit time consuming and I may pot them up to reduce feeding frequency.

The daily feed of fresh nutrients resets the nutrient concentration, pH, oxygen levels and temperature. The only thing I do differently for coco than rockwool or straight perlite is ignore runoff pH. Coco runoff does not give a good indication of the pH of the media. You need to core sample if you want to accurately establish the pH of coco.

That said, coco, watered daily with a consistent strength of nutrients, maintains a pH close to that of the original solution. For simplicity I pay the extra and use Canna, but not the whole line, just A+B and PK 13/14. I use one home made extra which is basically 1:1:1 seaweed, water and fermented molasses, sparingly during veg and regularly during flowering. It's also good for watering old coco that is up for recycling... helps breakdown the old roots.

The OP asked about pots... I like pots that have the whole bottom perforated rather than one that just have drain holes around the edge. I've managed to (mainly) scavenge a collection of pots that I use just for ganja. I tend to work with clones, if they are going to veg outdoors they end up in the big tubs, like the skunk clone pictured. If not, they flower in the 9L (2.4Gal).

I wont be going back to soil anytime soon.
