Rock Resinator Is a Late-Flower Phosphorus and Potassium Push
Bloom boosters are mostly phosphorus and potassium, and the useful ones say so plainly. This one runs a guaranteed analysis of 0-7-8. There is no nitrogen in it, which is the point during flower. Rock Nutrients state that the formula contains no plant growth regulators. The California Department of Food and Agriculture reviewed it and reported a positive influence on essential oil and resin production. Dose at 6 mL per gallon for a mild solution. Push to 10 mL per gallon when you want it stronger. Start in the second week of flower and run it through to harvest. It suits any medium and any system, from soil to recirculating hydro. Shake the bottle before every measure, because the formulation settles.
Where a 0-7-8 Bloom Booster Fits in a Feed Schedule
An additive is not a base nutrient and will not carry a crop on its own. Run it alongside whatever line you already use, in the same reservoir, at the stated rate. Because there is no nitrogen, it will not push green growth late in flower. Watch your EC when you add it, since it does contribute to total salts. Growers running coco or rockwool usually notice the change sooner than soil growers do. Three sizes are listed here: one litre, five litres and twenty litres. Small rooms rarely finish a five litre in a season. Commercial sites tend to skip straight to the largest container. Keep it sealed and out of sunlight and it holds for a long while.
