I can say this much for my experiments: they are all shit. Coco is not at all that great for creating roots. I believe there must be some plant science involved here that I am only just now grasping. My theory is because coco is so very good at holding moisture, the sprouts or cuttings have no reason to grow new roots since whatever roots they do have is obviously enough to allow for a constant supply of water. I have been afraid to to let the coco dry out in each of my experiments but I am almost wondering now if that's not exactly what I should be doing. This would force the plant to seek new water and thus grow new roots. I'm thinking coco in general is not what I need to be using at the begging stages of growth. I have been using it with some more mature clones that are vegging and they too seem to be held back slightly because of root growth. I think their beginning to over catch up at this point, but I'm pretty sure I could root faster in another medium. At least for the first month or so of vegging. Then transplant to coco for the final week of veg and then off to flower.

Also, I'm finding the coco I used, to be too fine. Apparently the premium type coco is not all that great for hydroponic situations. The coco begins to pack, not nearly as badly as dirt, but because it does this, it tends to hold water too long for recirculating systems. I believe the finer coco should be used in replace of soil, but it shouldn't have replaced my hydroton. I think I needed to get the husks or chunks if you will, which are a large particle and tend to dry out much quicker, thus allowing for faster cycles.

The spouts all seem to be taking their sweet ass time growing because literally the coco bed I made for them never drys out, not enough anyway to encourage root growth. Bummer.
