The commercial grower of 9 years.....
We mix in fresh bags of our soiless mix into the composted mix....
We toss our composted matts with a 40hp John Deer Tractor....
Adding the fresh bags of chemical free Farfard Custom mix with plenty of perlite for airation makes it easier to handled when refilling the trays.
Also we add Food Grade Sea Kelp MEAL,,,,,From Canada!


Happy growing.
