Funny this post popped up ....
Here something a bit different and surprisingly good.
I jumped off the FFOF train a couple months back and followed a grow by
@CptNemo ,
His grow was my inspiration to try . It is a CRF mix ( controlled release fertilizer ) and started from rapid rooter to present on WATER ONLY.
Fantastic growth - very aerated and no drama.
Original mix : 50/50 mix of both in lower half or third of your container then topped remainder with the garden soil .
My Mix : 50/50 mix as listed but added 25-30% chunky perlite - for more drainage and aeration.
I chose a layered mix - first the bottom " super " soil mix with perlite then 1/2 cup Light Warrior with Myco. Then topped with final Garden Soil mix with a bit of perlite.
You can leave the light warrior out , i used because i got bags of that stuff.
So far so good ... It is not very expensive and from LOWE's .
I added NOTHING to the soil for feeding and am on tap water only.
BTW i'm following your Quantum board thread and pulled the trigger on some.
