FullD..
You are testing my theory before i can
Love it.
Fingers Crossed...but seeing how your oxygenated water works..it has to be worth a shot.
Probably different to the thread you watched..but...
a Mossy K.I.S.S.
I have the air-stone in the top 1/3rd of the pot....
....
I want the oxygen for the tap root..to give it the oomph to dive to the bottom 2/3rds.
I have one of the flat long air stones....
so I put a 1/2 inch layer of perlite right across the top of the compo.
Bedded the stone there..Upside down..thinking the watered compo coming from above might clog it up..
so face down.
Then another thin layer of perlite above..
then the compo top.
I have it right in the middle and I have sown two rows of seed either side.
I Think that the lighter perlite surrounded by wet compo May make an oxygen pocket..
because it will be harder for the air to escape into the compo.
Line of least resistance.
If it works..I may add more air stones...
But hey..Test first eh...
If it fails..I have lost a few ALF#3..no hardship...
