Heavy 16 Bud A 4-0-2 Flowering Base
A two-part base keeps calcium away from phosphate and sulfate until both hit the reservoir, and this bottle is the calcium side. The guaranteed analysis is 4.0% nitrogen, 0% phosphate and 2.0% soluble potash. Almost all of that nitrogen is nitrate, with only a trace of ammoniacal nitrogen. Calcium comes in at 4.2%, drawn from four forms for steady availability. Those sources are calcium nitrate, calcium acetate, calcium gluconate and calcium chloride. Iron is supplied at 0.10% as both DTPA and EDDHA chelates. The EDDHA form keeps iron available as root zone pH climbs. A trace of molybdenum from sodium molybdate rounds out the formula. Potassium nitrate supplies the potash. It works in hydroponics, coco, soil and deep water culture. Field 16, the company behind Heavy 16, makes it in Signal Hill, California. The partner bottle carries the phosphorus, magnesium and sulfur.
Feeding a Bloom Base Nutrient in Equal Parts
Shake the bottle well, since natural settling is normal. Fill the reservoir with water first. Measure Bud A and add it to the tank. Rinse the measuring cup before dosing the partner bottle. Add an equal amount of Bud B. The label calls for 8 to 10 mL per gallon in early bloom. Step up to 10 to 12 mL in mid bloom and 12 to 15 mL late in the cycle. On the feed chart for soil, coco and hydro, each part runs at 10 mL for weeks one through six. It then drops to 6 mL in week seven and 4 mL in week eight. Deep water culture starts lower, at 8 mL for the first two weeks. Heavy 16 doses by mL per gallon rather than EC targets. With the brand's pH product in the mix, a starting range of 5.5 to 6.5 needs no adjustment. Aim for about 10% runoff per irrigation.
