Out of curiousity I did a search on this horticultural charcoal and
happened onto Paghat's website. I was a little surprised to find that
horticultural charcoal has absolutely none of the properties I thought
it had. I was going to put a layer on the bottom of the tank, covered
with a layer of weed fabric, then some pea gravel mixed with sand,
covered that with more fabric, then on top of that the promix. I want
to grow a number of things, all needing similar conditions, low light,
and dwarf. In one area I'm putting in a little zen area with raked
sand and some miniatures, etc.
So, is it my understanding I can eliminate the charcoal? Do you have
any recommendations regarding what mix ratio, etc? One last, can I
assume if only one fluorescent tube full spectrum 4' light would be
considered a low light situation if the tube is more than 24 inches
above plants. Is this a correct assumption?
Anyone with experience or knowledge is welcomed to give some advice. I
somehow think Paghat knows more than most people on the Internet...or
it looks to be so.
