thanks for all of your knowledge aquaman.Looks great man.
I think your seeing slower than expected results for a couple reasons.
1. Coco loco is more of a soil contrary to the name.
It's claimed to hold more water than it's own weight where as coco coir holds about 60%. Coco has a much higher air to water ratio and far more drainage so it can be watered extremely frequently and is hard to over water unlike coco loco.
Personal opinion only is that it will make a great soil but would never come close to comparing to a coco husk media in terms of growth rates under equal conditions. I also have a sneaking suspicion that it may contain coco coir pith in part or whole as the form of coco used.
2. The pot size will further reduce the speed of growth and time to dry back which is directly related to o2 exchange and air holding capacity.
You would likely see a better result using this in taller skinnier pots that would improve the air water ratio.
Same goes for smaller pots and transplanting up would likely see faster growth.
3. The organic amendments in it also increase the water over air volume.
I'd say what your seeing is about par for the course in the media being used for the pot and plants size.
I think you will see better results using a good wet dry cycle and starting in smaller pots, transplanting as you go.
