Im not closed minded to it and im not sure how you got that from my post. No i do not need to have bottom watered to understand how all these mechanics work and how they will effect various factors. I just understand the mechanics and implications it creates, thus this thread. I have grown many different ways in many different media ane dont feel its for me. If something works for someone they should embrace it and there is no 1 best method to growing… The best is the one that works for you.What is the challenge from watering below? lmo Roots exploding in res.
To answer your question on the challenges i need more info in the type of bottom watering because they are not all the same.
Is it a flood and drain style?
height of the flood in relation to the pot height?
organic (actual organic amendments) or synthetic?
type of containers used?
fresh nutrients or recirculated?
these and more all play a role in what challenges you may face.
