Why do virtually all experts water their CPs from the bottom up?
To me, this defies logic. *
Mother Nature doesn't routinely ooze and bubble up H2O from the bowels of the earth and furthermore; based on everything I have learned, CPs require good aeration.
Would not watering from above provide the requisite oxygenation these plants so desperately need to thrive?
Watering from below is nothing but wicking and I just don't think the capillary action would provide any added oxygen. Well, come to think of it watering from below would increase the relative humidity around the plant but a decent sized pea gravel tray filled with water does the same thing.
Which brings me to the next question. What does it matter what type of water goes into the pea gravel tray underneath the plants? We've all been using only distilled water to fill the trays but I question this practice when somebody has to lug all that bottled water up 3 flights of stairs into that classroom. So far the somebody lugging up all that water has been me. *
I do exclusively use either rain water or distilled water to water my plants and the school does too. This I understand and am not contesting.
