Product description
Aptus Super PK 1 L – PK bloom stimulator for every flowering run
If Super PK has earned a permanent spot in your bloom schedule, or you're filling bigger tanks, the litre bottle is the better buy at a lower price per litre than 500 ml.
What's inside
Aptus Super PK is a highly concentrated, organo-mineral PK bloom stimulator with 20% phosphorus and 23% potassium, plus L-amino acids and bloom-stimulating vitamins. The high P and K push flower formation and give a firm, compact end product. It's fully water-soluble with no residue, so it's at home in hydro and drip systems. With a pH of 8.5–9 it nudges your nutrient solution's pH up slightly.
Yield of 1 L
The dose is 2.5–5 ml per 10 L of water in flower; start at half the standard dose, and with sensitive plants begin only in week 4 or 5. One litre covers about 2,000 to 4,000 L of water. For an 80 L reservoir you add 20–40 ml.
Working with a reservoir
Because Super PK has a pH of 8.5–9, add it after your base nutrient and correct the pH only at the end, once everything is in. In recirculating tanks, check pH daily during the weeks you run it. The soluble formula leaves nothing behind in pumps or drippers. Store the bottle closed and frost-free.
