| A method of growing plants without soil. Instead a practically inert wicking medium transports water and fertilizer to the roots by capillary action. Medium contains a multitude of free air spaces and thus delivers oxygen to the roots.
I have read that hyd.culture Orchids can be planted in any container (not glass) with no drainage holes at the bottom but a few extra holes 3-5 cm up at the sides of the pot. The idea is to provide a water reservoir at the bottom of the container from which the medium wicks moisture to the roots.
But I think a lot will depend on the medium used. Maybe different mediums mean different wicking rates with the possibility of the roots becoming too moist. I would like to read opinions from the senior members. Bill |
