Hi guys if you don't mind me asking but why do people say you need a lot of water with coco?
Coco (coco peat, coco coir) = peat moss basically right? Which retains water?
It's not that it doesn't retain water...it's about how much it retains.
If you think of it as a spectrum as far as water retention, one end is DWC..then Hydroton...then soilless and or coco...followed by soil, that may be helpful.
Coco can't go as LONG without watering as straight soil. It retains water and nutrients, but only so much. Plus it's fairly "airy" so a pot of coco might weigh half as much as a pot of soil (wild guesstimate).
So if you've got say 100 gal's of straight coco, it may beable to retain 10 gallons of solution...whereas the same 100 gal's of soil maybe 20. (random numbers)
