[APD] Re: Heating Cables

["Phil Edwards" <biotypical at hotmail_com>]

In reviewing some of the discussion that Dupla espouses regarding the 
benefits of cables I am having a difficult time understanding any benefit. 
It would seem based on their logic that adding additional __flow__ of any 
kind would be detrimental, not benefitial.


I was thinking about that on the way out to Dallas and figured the long term 
benefit of cables is mostly due to the laterite/gravel type of substrate 
used at that time.  My thinking being that all the material that binds the 
nutrients is at the bottom of an otherwise inert substrate.  The cables then 
create a flow of water to bring the nutrients into that "rich zone" where 
chemicals can be sequestered.

Since the advent of "complete" substrates such as Flourite, our plants have 
been growing in a substrate composed entirely of bindable material.  As 
such, there is no practical benefit gained from current creating cables.  
Root draw action should be sufficient to replenish the sequestered nutrients 
throughout the entire substrate zone, maintaining a nutritious environment 
for our plants.

Just my thoughts.  I'd be interested in hearing yours,
Phil
