1 drop of triple-ammonium per 5 gallons of water.
I will not be planting directly in the horticultural sand (1/8 to 1/4 inch silicate). Its only purpose is to distribute heat laterally. Any cuttings or plants will be placed in 4 inch pots, which sit in 4 x 4 ring-flats. For rootings, I will likely use 50% coir + 50% perlite.
